Terms of Use

These terms govern your use of the Kravion website and the Kravion app for iOS. Please read them carefully; they describe what Kravion offers and what we can and cannot promise.

Last updated: 11 August 2026

1. Operator and scope

Kravion is operated by Stefan Radic, trading as Scailara Labs, Graf von Stauffenberg Allee 14, 60438 Frankfurt am Main, Germany (“we”). Full provider details are in the Impressum. These terms apply to the website and to the iOS app. For the app, Apple's App Store terms and Apple's licensing rules apply in addition; where they conflict for the app itself, Apple's terms prevail for the matters they govern.

2. Use of the service

Kravion is provided for your personal, lawful use. You are responsible for keeping your account credentials, sign-in codes and devices secure, and for activity carried out through your account. Do not interfere with the service, circumvent access controls, scrape it at scale, or use it in a way that harms other users or our infrastructure.

3. Editorial content

Book pages contain Kravion's own editorial interpretations and summaries. They are not reproductions of the original works, they may be incomplete or contain errors, and they do not replace reading the book. Nothing on Kravion is professional medical, legal, financial or psychological advice.

4. AI features

AI-generated output is produced automatically and can be inaccurate, outdated or misleading. Verify anything important before relying on it. AI output is not medical, legal, financial or psychological advice and creates no professional relationship.

5. Your contributions

You are responsible for the comments and replies you publish. Contributions must be plain text, on topic, and free of unlawful, abusive, harassing, discriminatory, infringing, deceptive or spam content, and must not disclose other people's personal data.

We may remove contributions, restrict publication or restrict an account where there is a justified reason, in particular a breach of these terms or of applicable law. Your statutory rights remain unaffected.

By publishing a contribution you grant us a simple, non-exclusive, free licence, limited to what is necessary to operate the discussion, to store, reproduce and display that contribution on the relevant book page. The licence ends when the contribution is deleted, except for copies retained in routine backups or where retention is legally required.

6. Intellectual property

The Kravion software, editorial texts, design, brand and other content are protected by law and remain ours or our licensors'. You may not copy, distribute, publicly make available, modify, decompile or reverse engineer them beyond what mandatory law expressly permits.

7. Premium subscriptions

Premium is purchased inside the iOS app through the Apple App Store. Billing, renewal, cancellation, restoring purchases and refunds are handled by Apple under your Apple account settings and Apple's terms; we do not process your payment data. Current prices and any trial conditions are shown at the point of purchase. Mandatory consumer rights, including statutory withdrawal rights where they apply, remain unaffected.

8. Availability and changes

Kravion is an evolving product. We may change, extend or discontinue features, and availability may be interrupted by maintenance, technical faults or events outside our control. You may stop using the service and delete your account at any time. We may terminate or suspend access for good cause, in particular serious or repeated breaches of these terms.

9. Liability

We are liable without limitation for intent and gross negligence, for injury to life, body or health, under any guarantee we have expressly given, and under the German Product Liability Act (Produkthaftungsgesetz).

In cases of slight negligence we are liable only for the breach of an essential contractual duty — a duty whose fulfilment makes proper performance of the contract possible in the first place and on whose observance you may regularly rely — and in that case only for the foreseeable damage typical for this type of contract. Any further liability is excluded. Mandatory statutory consumer rights remain unaffected.

10. Governing law and venue

German law applies. If you are a consumer with habitual residence in another EU member state, you additionally keep the protection of the mandatory provisions of the law of that state. Statutory rules on jurisdiction and venue apply.

We are not willing or obliged to participate in dispute resolution proceedings before a consumer arbitration board.

11. Changes to these terms

We may adapt these terms where there is a valid reason, for example changes to the product, to our infrastructure or to the legal framework. Where a change requires your agreement, we will inform you in an appropriate way and you may end your use of the service instead.

12. Severability and contact

Should a provision be or become invalid, the remaining provisions stay in force; the invalid provision is replaced by the applicable statutory rules. Questions about these terms: stefan@scailara.com. See also the Privacy Policy.
