Terms of Service

(1) These Terms apply to all contracts between the Provider (full legal disclosures see Imprint) and its customers (“Tenant Owner” or “Customer”) regarding the SaaS services available at zeptix.io and its subdomains.

(2) Conflicting terms of the Customer apply only if the Provider expressly accepts them in writing.

(3) These Terms apply to both consumers (§ 13 BGB — natural persons acting for purposes predominantly outside their trade, business or profession) and businesses (§ 14 BGB — natural or legal persons acting within their commercial or self-employed professional activity, including sole traders, freelancers, partnerships and corporations). Statutory consumer protections apply only where the Customer is a consumer within the meaning of § 13 BGB; they are expressly identified below.

(4) Conclusion of the contract requires the Customer to be of legal age and to have full legal capacity, or, in the case of legal entities, to be validly represented. By placing the order, the Customer confirms that it meets these requirements.

(1) Zeptix provides a multi-tenant platform for AI-powered chatbots. The Customer can configure a chatbot (name, logo, colors, system prompt), upload its own knowledge-base documents (PDF) which are used via Retrieval-Augmented Generation (“RAG”), and make the chatbot available to its end-users via a subdomain (<slug>.zeptix.io).

(2) The platform uses AI language models to deliver the service. Details on third-party service providers used, data categories and transfers are set out in the Privacy Policy.

(3) Note on AI behavior: Chatbot responses are generated by AI models and may contain factually incorrect, incomplete or inappropriate content (“hallucinations”). The Customer is responsible for the substantive review of bot responses and for informing its end-users about the AI nature of the service.

(4) Zeptix does not owe any specific outcome of bot responses. What is owed is the technical provisioning of the platform with the features and quotas described in the booked plan.

(5) Roles under the EU AI Act: To deliver the service, Zeptix uses general-purpose AI models of third parties and thereby acts as a deployer within the meaning of Regulation (EU) 2024/1689. The Customer is the deployer of its specific chatbot. The transparency obligations under Art. 50 AI Act (notice of the AI nature towards end-users from 2 August 2026; machine-readable marking of synthetic content from 2 December 2026) are supported at platform level (including the AI-disclosure modal and end-user terms). The Customer ensures that, where it designs the bot itself or embeds it in its own interfaces, it complies with the transparency obligations applicable to it.

(1) The Customer retains all rights in the content it provides (knowledge-base documents, inputs, configuration, logo, text).

(2) The Customer grants Zeptix a simple, non-exclusive license, limited to the contract term and serving solely the provision of the service, to store, process, split into chunks, embed (RAG) and — where necessary to generate a response — transmit such content to the AI providers used. No use beyond this takes place.

(3) No AI training: Zeptix does not use Customer content, end-user inputs or bot outputs to train its own or third-party AI models. Details are governed by the privacy policy.

(4) Bot outputs: As between the parties, the responses generated by the chatbot are available to the Customer for contractual use. Zeptix claims no own rights in the outputs, apart from the processing necessary for service delivery and for compliance with legal obligations (e.g. security, moderation).

(5) No warranty of protectability: AI-generated outputs may not be protectable by copyright, or only to a limited extent, and are not necessarily unique — identical or similar outputs may also arise for other customers. Zeptix gives no warranty as to the protectability, originality or non-infringement of individual outputs. The Customer reviews outputs on its own responsibility before any commercial use (see also § 2 (3), § 9 (5)).

(1) Zeptix may offer a time-limited free trial (“Self-Serve Trial”) that lets interested users register without providing a payment method and without selecting a plan beforehand and create and test their own chatbot. The trial currently runs for 14 days from activation and provides Starter-level features with reduced quotas (in particular one chatbot and a limited credit allowance).

(2) The trial is a voluntary, non-binding offer. There is no entitlement to its grant, availability or continuation. Zeptix may — in particular during the launch/soft-launch phase and subject to available capacity — limit the number of trials, change their scope, duration and conditions at any time, or discontinue them entirely. Trials already activated are generally not shortened retroactively.

(3) As a rule, one trial is granted per account and person. Abusive multiple use (e.g. via several accounts) is not permitted.

(4) During the trial the chatbot remains private; publishing it (making it publicly live) is only possible with a paid plan.

(5) As there is no payment obligation, the trial does not create a paid continuing-obligation contract; there is no automatic conversion into a paid plan and no automatic charge. If the customer does not choose a paid plan within the trial period, the chatbot is deactivated after expiry. Configuration, knowledge base and chatbot data are retained for 30 days after the trial ends so that reactivation via plan selection or a data export remains possible; thereafter they are deleted unless statutory retention obligations apply (cf. § 6(5)).

(6) If the customer subsequently concludes a paid plan, these Terms apply to it, including the provisions on conclusion of contract (§ 3), plans and prices (§ 4), term and termination (§ 6) and the right of withdrawal for consumers (§ 12).

(1) The presentation of plans on zeptix.io does not constitute a binding offer, but an invitation to the Customer to submit an offer.

(2) The Customer makes its offer by completing the order process. By clicking “Order with obligation to pay”, the Customer submits a binding offer.

(3) The contract is concluded once Zeptix accepts the offer by confirmation e-mail or activates the account.

(4) The contract text is stored electronically; access is provided via the tenant dashboard. Consumers are provided with confirmation of the contract, including these Terms, on a durable medium (§ 312f BGB), as a rule by e-mail, within a reasonable period after conclusion of the contract.

(1) The plans, prices and quotas displayed on zeptix.io at the time of order apply. An overview of the current plans (in particular Starter, Pro, Business and any special or promotional plans) is available at zeptix.io/pricing. Upon ordering, the plan conditions displayed there (number of bots, document quota, message limits, token quota, price, billing period) become part of the individual contract. The order confirmation or invoice documents the conditions booked in the specific case.

(2) All displayed prices are gross final prices in Euro including the statutory VAT, where applicable (§ 1 (1) PAngV). As a sole trader, the small-business scheme under § 19 UStG may apply — in this case the invoice does not show VAT, but the displayed gross price remains unchanged. Should the small-business scheme cease to apply in the future, the VAT will be calculated out of the displayed gross price — no price increase will result from this. Towards businesses, any applicable VAT is shown separately on the invoice.

(3) Launch and Early Bird conditions remain locked in for existing subscribers as long as the respective subscription stays continuously active. New subscriptions may later start at regular prices.

(4) Definitions:

• “Free visitor message” means a successfully answered request of an end-user, as long as the Customer has not activated a visitor paywall or as long as the individual end-user has not yet triggered a paywall. Failed calls do not count.
• “End-user plan limit” means a message quota configured by the Customer for an end-user and a billing or reset period. It does not create any entitlement of the end-user against Zeptix to permanent free use.
• “Free credits” are voluntary, non-cash usage units granted by the Customer to end-users. They have no cash value, are non-transferable and may be granted once or periodically depending on the Customer's configuration.
• “Owner test token” means input and output tokens consumed by the LLM in owner-initiated test chats (dashboard, setup, prompt tuning) — including all knowledge-base excerpts injected via RAG and the conversation history sent. A typical cycle consumes approx. 1,900 tokens.
• “Knowledge-base document” means a file uploaded by the Customer (PDF) that is split into chunks, embedded locally, and indexed for RAG retrieval. Storage and embedding are included in the plan.

(5) Daily limit (spike protection): When the daily limit of free visitor messages is reached, the chatbot will respond to new free visitor requests with a notice instead of an AI response, until 00:00 (Europe/Berlin) of the following day. Daily counting is tenant-wide across all bots of the Customer. Once the visitor paywall is available and activated by the Customer, end-users will pay per message via the credit system after their free quota is exhausted (or directly).

(6) Monthly owner-token quota (fair use): When the owner test token quota is reached, further owner-initiated test chats are no longer possible until the start of the next billing month. Visitor messages paid for by end-users via an active paywall are not affected. The Customer can switch to a higher plan or book a token booster at any time. Excess usage is not credited against the following month.

(7) Advance notification: Upon reaching 80% of the daily or monthly limit, Zeptix will, where possible, notify the Customer via e-mail or dashboard banner. There is no entitlement to such notification — the Customer remains responsible for monitoring its own usage.

(8) Boost add-ons: Additional features (e.g. token booster, web search tool, voice output, multi-language pack) will be released gradually and can be booked across plans. The applicable conditions will be displayed at the time of booking in the dashboard. Features marked as “beta” or “early access” are provided “as is” without warranty of uninterrupted availability or specific characteristics and may be changed or discontinued at any time.

(9) End-user billing, free plan and credits: Depending on the enabled feature set, the Customer may configure whether end-users chat via plan messages, credits, a combination of both, or without visible end-user quotas. Free plan values and free credits are technical usage limits or goodwill quotas; they are not a means of payment, have no cash value, are non-transferable and do not create any entitlement to a specific number of future answers. The Customer is responsible for not misleading end-users about free quotas, reset dates, upgrades or voluntary credit top-ups. Purchased end-user credits are kept for the respective bot or tenant only, unless the checkout states otherwise.

(9a) Credits are not a wallet / not e-money: Credits — whether owner-pool credits of the Customer or end-user credits — are purely technical usage units for AI responses inside the respective chatbot or tenant. In particular, they are non-redeemable for cash, not transferable (neither between bots nor between accounts or persons), not tradable (no peer-to-peer, no swap), not a wallet, not an account and not a payment instrument within the meaning of the German Payment Services Supervision Act (ZAG). Credits are not electronic money within the meaning of § 1a (3) ZAG because they are issued solely in consideration of the specific AI answering service in the respective chatbot (analogous to the “limited network” exemption under § 1a (5) ZAG). They are not a cryptocurrency, token or NFT and not an investment product. The Customer undertakes never to advertise or present credits to end-users as a wallet, account, investment product, crypto-asset or tradable good.

(9b) No earnings guarantee: Where the Customer uses Mode B or Business Direct, Zeptix does not guarantee any particular level of revenue, turnover, reach or share. Specific euro amounts on marketing pages, in the dashboard or in example calculators do not constitute a promise; they serve illustrative purposes only. Actual earnings depend on factors controlled solely by the Customer (traffic, conversion rate, pricing, chosen AI tier, refund / chargeback rate). The Customer must not make any income or return promises to end-users or third parties that conflict with this clause.

(10) Visitor paywall / end-user monetisation — separate agreement: If the Customer activates end-user monetisation in the so-called Zeptix-first mode (platform Stripe / Mode B) via the dashboard, Zeptix acts as the seller (Merchant of Record) of credits and visitor subscriptions to the end-users. Activation requires the explicit, individual acceptance of the Owner Revenue Share & Platform Stripe Agreement inside the dashboard. That agreement governs the seller role, owner share, payouts, refund and chargeback handling and termination in a binding way and takes precedence over these terms in case of conflict. Until that acceptance is recorded, the mode cannot be technically enabled. If the Customer instead switches to Business Direct (own Stripe Connect account, Business plan), the Customer is the contractual partner of the end-users; Zeptix then receives an agreed platform fee and all consumer-law obligations vis-à-vis the end-users lie with the Customer.

(11) Price changes for recurring fees will be announced at least 30 days before they take effect via e-mail. The Customer has a special right of termination at the time the new price takes effect.

(1) Principle. The free-visitor messages provided in free-visitor mode (§ 4) are economically subsidised by Zeptix, as Zeptix bears the inference costs. The Customer may not use them to offer access to the chatbot to end-users for a fee and thereby circumvent the official visitor-paywall / credit system (§ 4).

(2) Definition of „bot-access fee". A bot-access fee exists where the Customer directly or indirectly charges end-users a separate or additional fee whose essential consideration is access to the chatbot or the use of its answers — for example a paywall, a login or a subscription that specifically unlocks the chatbot, or a per-message or usage-based fee for bot answers.

(3) Prohibition of circumvention. As long as a bot is operated in free-visitor mode, charging a bot-access fee outside the official visitor-paywall / credit system is prohibited. Prohibited in particular are hiding the bot behind the Customer’s own bot-specific paywall, reselling, renting or sublicensing bot access, as well as technical arrangements with the same economic result. Anyone who wishes to serve end-users for a fee must activate the visitor paywall or switch to a suitable plan.

(4) Expressly permitted — embedded ancillary function. The embedding of the chatbot as a non-independent auxiliary or ancillary function within a separately priced product, service or customer / member portal of the Customer remains permitted, provided that predominantly:

• the fee is charged for a product or service that has independent value even without the chatbot,
• the chatbot is not presented as the priced or advertised main service and is not priced separately, and
• the fee does not depend on the use of the chatbot (in particular not per message or question).

(5) Branding notice. In free-visitor and Starter mode the chatbot displays a „Powered by Zeptix" notice. Removing or concealing it is permitted only within the plans provided for this purpose (white-label from Business).

(6) Evidence and review. Where there is reasonable suspicion of circumvention, Zeptix is entitled to review the tenant-wide usage patterns (in particular volume and the embedding origin domains) and to request from the Customer a comprehensible explanation of the deployment scenario.

(7) Consequences. In the event of a breach, Zeptix will first notify the Customer of the circumvention and request remedy (activation of the visitor paywall or a plan change). If the circumvention is not stopped within a reasonable period, Zeptix is entitled to throttle or suspend the affected bot and to terminate the contract extraordinarily for good cause (§ 6 (3)). Further claims for damages remain unaffected.

(1) Payments are processed via Stripe Payments Europe, Limited (Dublin, Ireland). Stripe’s payment terms apply.

(2) Accepted payment methods: credit/debit cards, SEPA direct debit, and other methods supported by Stripe.

(3) Fees are due in advance at the start of the billing period.

(4) Payment default: If a payment fails and remains unpaid after a reminder with a reasonable deadline, Zeptix is entitled to suspend the account. Existing data is retained for 30 days.

(1) The contract is concluded for an indefinite term with a minimum term equal to the chosen billing period (1 month for monthly, 12 months for annual billing).

(2) Automatic renewal: After the minimum term ends, unless previously terminated, the contract automatically renews on a month-to-month basis (Fair Consumer Contracts Act / § 309 No. 9 BGB amended version). For annual billing, after the first 12 months the contract likewise renews monthly with a one-month notice period; a new 12-month commitment only arises if actively re-selected by the Customer.

(3) Termination in text form is possible at any time with effect at the end of the current billing period. Zeptix provides a cancellation button in line with § 312k BGB which is reachable without prior login. Alternatively, an e-mail to [email protected] or a click in the account area is sufficient. Receipt is confirmed electronically with a reference number.

(4) The right of extraordinary termination for cause remains unaffected — in particular for breach of § 7, circumvention of the monetisation system under § 4a (not remedied despite request), payment default of two monthly installments, or unlawful use. In case of a justified extraordinary termination by the consumer, Zeptix reimburses the unused portion of the fee on a pro-rata basis.

(5) Data export and chatbot retention: The Customer can export all content until termination takes effect. After contract end, the affected chatbot is deactivated and displays a corresponding notice to end-users. Configuration, knowledge base and chatbot data are retained for 60 days so that export, reactivation or support cases remain possible. After that period, the chatbot is automatically deleted unless statutory retention obligations or legitimate proof interests require otherwise. The export is provided in a common, structured and machine-readable format.

(1) Subscription fees are due at the start of each billing period and are generally non-refundable, unless mandatory statutory rights (withdrawal under § 12, defect rights under § 9, extraordinary termination under § 6 (4)) require otherwise.

(2) Credit packs / top-ups (Customer’s own use): one-off credit packages (owner-pool credits) are non-refundable after activation because the digital credits become immediately usable (cf. § 356 (5) BGB for consumers). Already credited balances are not paid out. For demonstrably unused credit packs within 14 days of purchase, Zeptix may, at its discretion, refund the gross purchase price less Stripe fees, provided the consumer did not explicitly consent to immediate performance.

(3) End-user purchase refunds (Zeptix-first / platform Stripe): In the event of an end-user purchase refund (e.g. via Stripe dispute or goodwill), the originally granted credits are clawed back from the end-user balance; any related Owner share is set to reversed. Details are governed by the Owner Revenue-Share Agreement.

(4) Marketplace knowledge packs: one-off purchased knowledge packs are digital content. Consumers lose their withdrawal right upon activation (consent to immediate performance at checkout). Up until activation, the purchase can be withdrawn within 14 days.

(5) Stripe chargebacks: in case of chargebacks, Zeptix reserves the right to temporarily suspend the affected account and to claw back granted credits until the matter is conclusively resolved. Unjustified chargebacks may constitute grounds for termination under § 6 (4).

(6) Refunds are issued exclusively to the same payment method used for the original purchase, unless mandatory legal reasons require a different procedure.

(1) The Customer undertakes not to use the service for unlawful purposes, in particular not for content infringing applicable law (criminal law, youth protection, competition law), violation of third-party rights, spam, phishing, distribution of malware, automated mass requests without prior agreement, or content that promotes hate, violence or discrimination.

(2) The Customer warrants that it holds all necessary rights to all uploaded, entered or training-AI-assisted content and that the content does not infringe third-party rights.

(3) The Customer is responsible for its access credentials. In case of suspected abuse, Zeptix shall be informed immediately.

(4) The Customer is obliged to comply with the joint controllership agreement (Art. 26 GDPR) concluded with Zeptix and in particular to inform its end-users in its own privacy policy about the use of the chatbot.

(5) Prohibited use cases — high-risk AI: The Customer undertakes NOT to use the service for high-risk AI applications within the meaning of Art. 6 in conjunction with Annex III of Regulation (EU) 2024/1689 (“EU AI Act”). This includes in particular: biometric remote identification; assessment of applicants or employees; assessment of educational performance or examinations; creditworthiness scoring; asylum, migration or visa decisions; law enforcement; management of critical infrastructure. A separate enterprise contract is required for such use.

(6) Prohibited use cases — special data categories: The Customer shall not process special categories of data under Art. 9 (1) GDPR in the chatbot (in particular health data, ethnic origin, political opinions, religious or philosophical beliefs, trade union membership, sexual orientation, biometric data for unique identification), unless the Customer has previously booked an extended plan (“Enterprise EU-Strict”) in writing and Zeptix has confirmed the necessary technical and organizational measures in writing.

(7) Prohibited use cases — professional secrets: The Customer shall not process data subject to professional or special confidentiality protection in the chatbot — in particular no client data of attorneys (§ 43a BRAO), no patient data (§ 203 StGB), no social data (§ 35 SGB I), no confessional or pastoral secrets. The Customer shall ensure through its own technical and organizational measures that such data cannot enter the chatbot.

(8) Consequences of breach: In case of breach of paragraphs (5), (6) or (7), Zeptix is entitled to extraordinary termination without notice. All resulting fines, damages claims or other third-party claims shall be borne exclusively by the Customer; the Customer shall fully indemnify Zeptix in this respect.

(9) The Customer indemnifies Zeptix against all third-party claims arising from breaches of the above obligations, including reasonable legal defense costs.

(10) API access and webhooks: Where the Customer uses read-only API access or webhooks, it keeps its API tokens confidential and is responsible for all access made via its tokens. It observes any usage and rate limits (fair use), does not circumvent technical protection or limitation mechanisms and does not reverse-engineer the service. The Customer is itself responsible for the processing of data transmitted to a webhook endpoint operated by the Customer.

(1) The Customer undertakes to review and process reported incidents concerning its chatbot — in particular end-user reports in the dashboard “Feedback” tab and automated platform safety triggers — within 48 hours of receipt.

(2) For reports of harmful content (violence, hate, self-harm) or legally problematic content (instructions for crimes, infringement of personality rights), the response deadline is reduced to 24 hours. In case of suspected child abuse, terrorism or acute danger to life or health, immediate response is required.

(3) “Processing” for the purposes of this § 7a covers at least: (a) review of the reported answer, (b) correction of the knowledge base, system prompt or bot personality if the report is justified, (c) suspension of the affected end-user in case of abusive inputs, (d) marking the report as “resolved” in the dashboard.

(4) If the Customer fails to respond in time, Zeptix is entitled to take the affected bot temporarily offline, restrict individual features (e.g. new end-user registrations) or — in case of repeated or severe violations — terminate the contract for cause (§ 6 (3), § 7 (8)).

(5) In cases of acute danger (in particular suicide indications, concrete violence threats, indications of child abuse), Zeptix is entitled to act directly — even without prior information of the Customer — to inform emergency services or law enforcement (Art. 6 (1) d GDPR). The Customer shall be informed without undue delay afterwards.

(6) This moderation duty supplements the Acceptable Use Policy and the joint controllership agreement (Art. 26 GDPR).

(7) Statement of Reasons (DSA Art. 17): If Zeptix restricts a bot or an account due to a violation, the affected Customer receives a written statement of reasons in text form, including (a) the specific measure, (b) the underlying facts and sources (e.g. end-user report, automated safety trigger, internal investigation), (c) the provisions of the Terms / AUP / law violated, (d) the option of internal appeal (e-mail to [email protected]) and (e) reference to the possibility of out-of-court dispute settlement or court proceedings.

(1) Zeptix endeavors to achieve an average annual availability of 99.5 %, measured over the calendar year and excluding planned maintenance windows.

(2) Planned maintenance windows will, where possible, be scheduled outside normal business hours (Mon–Fri, 9–18 CET/CEST) and announced at least 24 hours in advance.

(3) There is no contractually guaranteed SLA with penalties unless a separate enterprise contract provides otherwise.

(4) Third-party provider outages: If an external service provider used fails, Zeptix endeavors to perform automatic failover. If this is not possible, the outage may qualify as a circumstance not attributable to Zeptix.

(5) Force majeure: Zeptix is not liable for performance disruptions due to events of force majeure (in particular natural disasters, pandemics, war, strikes, large-scale power or internet outages, official measures or severe cyberattacks). For the duration of such events, the affected performance obligations are suspended.

(1) Statutory defect rights apply, subject to the following:

(2) Towards consumers, statutory warranty rights remain unaffected. The limitation period is two years from provision under § 327j BGB.

(3) Towards businesses, the limitation period is one year from provision. Defects must be reported in text form immediately upon discovery.

(4) The warranty does not extend to defects caused by improper use, third-party interference or configuration errors caused by the Customer, nor to substantive errors in knowledge-base documents uploaded by the Customer or in the system prompt set by the Customer.

(5) The warranty expressly does not extend to individual AI responses (“hallucinations”, see § 2 (3)).

(6) Updates (§ 327f BGB): During the provision period, Zeptix provides the updates necessary to maintain conformity, including security updates, and informs consumers thereof. As the service is provided as hosted software (SaaS), updates are generally applied server-side automatically without action by the Customer.

(1) Zeptix is liable without limitation for intent and gross negligence, injury to life/body/health, claims under the Product Liability Act, and fraudulently concealed defects.

(2) For simple negligence, Zeptix is liable only for breach of essential contractual obligations (“cardinal duties”) and limited in amount to typical, foreseeable damage.

(3) Essential contractual obligations are those whose fulfillment is necessary for the proper performance of the contract.

(4) Liability for simple negligence is limited in amount to the typical, foreseeable damage; as a monetary guideline, the fees paid in the last twelve months generally apply. Any liability beyond this for simple negligence is excluded, unless paragraph 1 mandatorily provides otherwise.

(5) Data loss: Liability is limited to the typical recovery effort assuming regular backup creation.

(6) Liability for lost profit, lost savings, indirect and consequential damages is excluded for simple negligence.

(7) The above limitations also apply to the personal liability of employees, representatives and vicarious agents.

(8) Indemnification by Zeptix: Zeptix indemnifies the Customer against justified third-party claims based on the fact that the contractual use of the platform itself — but not the content introduced by the Customer or its configuration — infringes third-party rights. This requires that the Customer informs Zeptix of the claims without undue delay, makes no admissions, and leaves the legal defense and settlement negotiations to Zeptix.

(1) The processing of personal data is governed by the separate privacy policy.

(2) Insofar as the Customer processes personal data of end-users with its chatbot, Zeptix and the Customer are joint controllers within the meaning of Art. 26 GDPR. The required agreement becomes effective between the parties upon contract conclusion.

(3) The primary model is joint controllership under paragraph (2). Insofar as Zeptix exceptionally processes personal data exclusively on the Customer’s instructions, a processor relationship (Art. 28 GDPR) applies. The provisions required for this under Art. 28 (3) GDPR (subject matter, duration, nature and purpose of processing, categories of data, categories of data subjects, and the obligations and rights of the controller) are made available by Zeptix to the Customer on request as a separate data processing agreement; this must be concluded before any instruction-based processing.

(4) The TOMs (technical and organizational measures) under Art. 32 GDPR can be requested from the Provider.

Applies exclusively to consumers (§ 13 BGB). Businesses (§ 14 BGB) — i.e. sole traders, freelancers, partnerships, corporations and all persons using Zeptix in the course of their commercial or self-employed professional activity — have no statutory right of withdrawal.

Instructions on Withdrawal

You have the right to withdraw from this contract within fourteen days without giving any reason. The withdrawal period is fourteen days from the day of conclusion of the contract.

To exercise your right of withdrawal, you must inform us — Alexander Sadomsky (Zeptix), c/o IP-Management #42121, Ludwig-Erhard-Str. 18, 20459 Hamburg, e-mail [email protected] — by an unequivocal statement of your decision to withdraw. Sending the notice before the deadline is sufficient to meet the deadline.

Consequences of withdrawal. If you withdraw from this contract, we will reimburse all payments received from you without delay and at the latest within fourteen days from the receipt of the notice of withdrawal. For the reimbursement we will use the same means of payment as used for the original transaction.

Early expiry of the right of withdrawal (§ 356 (4) / (5) BGB): The right of withdrawal expires where the consumer has expressly consented in the order process to Zeptix commencing performance immediately after contract conclusion, and has simultaneously confirmed their knowledge that they lose the right of withdrawal upon commencement of performance. This consent is collected as a mandatory checkbox in the onboarding step “Legal acceptances” and stored with IP address, user agent and timestamp (Art. 7 (1) GDPR). Once the consumer ticks this checkbox, the right of withdrawal expires upon activation of the account.

For consumers who do not grant consent to immediate commencement: the 14-day withdrawal period runs from contract conclusion. During this period the service cannot be used. A dedicated withdrawal page is available at zeptix.io/widerruf.

Model withdrawal form

To: Alexander Sadomsky (Zeptix), c/o IP-Management #42121, Ludwig-Erhard-Str. 18, 20459 Hamburg, [email protected] I/We (*) hereby give notice that I/We (*) withdraw from my/our (*) contract for the provision of the following service (*): Ordered on (*) / received on (*): Name of consumer(s): Address of consumer(s): Signature of consumer(s) (only if this form is notified on paper): Date: (*) Delete as appropriate.

(1) Zeptix reserves the right to adjust these Terms where necessary for legal or technical reasons.

(2) Material changes will be communicated to the Customer at least 30 days before they take effect by e-mail. If the Customer does not object within this period, the changed Terms are deemed accepted. The Customer is separately informed of the right to object and the legal consequence of silence.

(3) In the event of an objection, Zeptix has the right to terminate the contract extraordinarily as of the date the changes take effect.

(1) Form requirement: Changes or additions to these Terms require text form (§ 126b BGB). This also applies to the change of this form requirement.

(2) Place of jurisdiction: If the Customer is a merchant, legal entity under public law or special fund under public law, Hamburg shall be the exclusive place of jurisdiction.

(3) Applicable law: German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. For consumers, mandatory consumer protection provisions of the country of habitual residence remain unaffected.

(4) Consumer dispute resolution: Zeptix is neither willing nor obliged to participate in dispute resolution proceedings before a consumer arbitration board.

(5) Severability clause: Should individual provisions be or become invalid, the validity of the remaining provisions shall not be affected.

(6) Assignment / transfer of contract: Zeptix is entitled to transfer the rights and obligations under this contract to a legal successor in the course of a restructuring or sale of the business. Consumers will be informed of this at least 30 days in advance and, in that case, have a special right of termination effective as of the transfer.

Current version: 05.06.2026
