These Terms of Service (“Terms”) govern access to and use of the Service. By creating an account, placing an order, or otherwise using the Service, the user (“User”) accepts these Terms in the version in force at the time of use.
Conflicting or supplemental terms proposed by the User do not apply, even where Kairos Alpha GmbH has not expressly objected.

The User is liable for activity conducted under the account until notice of unauthorised access is given to Kairos Alpha GmbH. Accounts may not be transferred.

The contract for payment is concluded between the User and Polar; the contract for use of the Service is concluded between the User and Kairos Alpha GmbH. Invoices, refunds, and tax matters are handled by Polar in accordance with Polar’s terms.
Subscription fees, billing cycles, and currencies are as stated at checkout. Renewal is automatic unless cancelled before the end of the current term.
5. Right of withdrawal for consumers (Widerrufsbelehrung, §312g BGB)
Consumerswithin the meaning of §13 BGB have the right to withdraw from this contract within fourteen (14) days without giving any reason. The withdrawal period expires fourteen days after the day of conclusion of the contract.
To exercise the right of withdrawal, the User must inform Kairos Alpha GmbH (info@re-nterprises.com, Curschmannstr. 31, 20251 Hamburg, Germany) of the decision to withdraw by an unequivocal statement (e.g., a letter or email). The model withdrawal form set out in Annex 1 to Art. 246a EGBGB may be used but is not mandatory.
Loss of right of withdrawal for digital content (§356 V BGB): where the Service consists of digital content not supplied on a tangible medium, the right of withdrawal expires if performance has begun after the User (i) has given express prior consent to performance before the end of the withdrawal period and (ii) has acknowledged that this consent results in loss of the right of withdrawal. Such consent is obtained at checkout.

6. Intellectual property and licence
All rights, title, and interest in the Service, including software, design, trademarks, and documentation, remain with Kairos Alpha GmbH or its licensors. The User is granted a non-exclusive, non-transferable, revocable licence to use the Service for the duration of the subscription, subject to these Terms.
The User retains ownership of content uploaded to the Service (“User Content”) and grants Kairos Alpha GmbH a worldwide, royalty-free, sub-licensable licence to host, store, reproduce, and process User Content solely to the extent necessary to provide and improve the Service.
7. Acceptable use
The User must not (a) reverse engineer the Service except as permitted by §69e UrhG; (b) upload content infringing third-party rights or violating applicable law; (c) interfere with the technical operation of the Service; (d) use the Service to send unsolicited communications.
8. Availability and changes
Kairos Alpha GmbH endeavours to keep the Service available but does not guarantee uninterrupted operation. Scheduled maintenance and updates may temporarily restrict access. Kairos Alpha GmbH may modify features of the Service provided the contractual purpose is preserved. Beyond changes necessary to keep the digital product in conformity with the contract, Kairos Alpha GmbH may modify the digital product only for a valid reason, at no additional cost to the User, and with advance notice. Where such a modification more than insignificantly impairs the User’s access to or use of the digital product, the User may terminate the contract free of charge within thirty (30) days of being notified of the modification, or of the modification taking effect, whichever is later (§ 327r BGB).
9. Term and termination
The contract runs for the chosen subscription term and renews automatically. The User may terminate at any time with effect from the end of the current billing period through the account settings or by notice to info@re-nterprises.com. Kairos Alpha GmbH may terminate for cause, in particular for material breach of these Terms, with or without prior notice as proportionate. Statutory rights of termination for good cause (§314 BGB) remain unaffected.
10. Liability
Kairos Alpha GmbH is liable without limitation for damages caused intentionally (Vorsatz) or by gross negligence (grobe Fahrlässigkeit), for injury to life, body, or health, under any guarantee expressly assumed, and under mandatory product-liability legislation (Produkthaftungsgesetz).
For slight negligence, Kairos Alpha GmbH is liable only where an essential contractual obligation has been breached — that is, an obligation whose fulfilment makes the proper performance of the contract possible in the first place and on whose observance the User may regularly rely. In that case liability is limited to the foreseeable damage typical for this type of contract. Any further liability for slight negligence is excluded.
As between business users (B2B), the aggregate liability of Kairos Alpha GmbH for damages arising under or in connection with the contract is capped at the total fees paid by the User in the twelve (12) months preceding the event giving rise to liability. This cap does not apply to the cases of unlimited liability set out above (intent, gross negligence, injury to life, body, or health, assumed guarantees, and statutory product liability).
Mandatory statutory rights of consumers (B2C) remain unaffected. None of the limitations in this section applies where, or to the extent that, the law prohibits their limitation (§307 BGB in conjunction with §309 Nr. 7 BGB).
11. Data protection
Processing of personal data is described in the Privacy Policy. B2B controllers may enter into the Data Processing Addendumwhere Kairos Alpha GmbH processes personal data on the User’s behalf.
12. Dispute resolution
The EU Online Dispute Resolution platform was discontinued on 20 July 2025 and is no longer available. Kairos Alpha GmbH is neither obliged nor willing to participate in dispute resolution proceedings before a consumer arbitration board (Verbraucherschlichtungsstelle) within the meaning of §36 VSBG.
13. Governing law and venue
These Terms are governed by the laws of the Federal Republic of Germany, excluding the UN Convention on Contracts for the International Sale of Goods. For consumers habitually resident in another EU member state, mandatory protective provisions of that state remain unaffected.
Exclusive venue for disputes with merchants, legal persons under public law, or special public-law estates is Hamburg.
14. Final provisions
Amendments require text form (§126b BGB). Should any provision be invalid, the validity of the remaining provisions is unaffected; the invalid provision is replaced by a provision approximating the economic intent of the parties.
