Lullacraft — Terms of Use

Effective Date: 2026-06-04.

These Terms of Use (the “Terms”) form a binding agreement between you (“you”, “your”) and Sanva Independent Developer (the “Operator”, “we”, “us”, “our”) governing your access to and use of the Lullacraft mobile applications, the website at sleepwise.sanva.tk, and any related services (collectively, the “Service”). By creating an account or using the Service, you agree to these Terms.

1. Service Description

Lullacraft is a wellness utility app that helps you wind down before bed. It provides AI-guided meditation scripts, breathing animations, and a local sleep journal. Each session is composed fresh around your goal, what’s keeping you up, and your mood. The Service relies on a third-party AI gateway to generate guidance text.

Lullacraft is not a medical device and does not offer diagnosis, treatment, prescription, or psychotherapy services. We may update, modify, or discontinue features at any time. Material changes affecting paid users will be communicated as described in Section 13.

2. Eligibility

You must be at least 13 years old (or 16 if you are in the European Economic Area, or the minimum age set by your local law) to use the Service. By using the Service, you represent and warrant that you meet this age requirement and have the legal capacity to enter into these Terms.

3. Your Account

You are responsible for:

  • Maintaining the confidentiality of your sign-in method (Sign in with Apple, or email magic link).
  • All activity that occurs under your account.
  • Notifying us at privacy@sanva.tk if you suspect unauthorized use.

We may suspend or terminate accounts that violate these Terms, applicable law, or that we reasonably believe pose a risk to the Service.

4. Acceptable Use

You agree not to:

  • (a) violate any applicable law or regulation, or any third party’s rights;
  • (b) attempt to reverse-engineer, decompile, or extract our or our processors’ models, prompts, or systems;
  • (c) probe, scan, or test the vulnerability of the Service, or breach security or authentication measures;
  • (d) interfere with the Service, our infrastructure, or other users’ use of it;
  • (e) use the Service to generate, store, or share unlawful or harmful content.

5. Your Content and Data

Your practice records, sleep journal entries, and preferences are stored on your device by default. When generating an AI script, only the non-identifying fields needed for personalization (your goal, blocker, mood, and recent practice signals) are sent to the AI gateway. See the Privacy Policy for details.

You retain all rights in the journal entries and preferences you create. We do not claim ownership of them, and we do not use your content to train any AI model.

6. Health Notice

Lullacraft is intended for relaxation and general wellbeing only. AI-generated guidance:

  • May be inaccurate, incomplete, or unsuitable for your specific situation;
  • Is not medical, psychological, or professional advice;
  • Should not be used to diagnose, treat, or manage any health condition.

If you experience persistent insomnia, anxiety, or related health concerns, please consult a qualified medical professional.

7. Subscriptions, Trials & Billing

The Service offers a free tier and paid Lullacraft Pro plans (weekly, monthly, and yearly), each including a free trial. Pricing, billing cycles, and cancellation details are set out on our Subscription Terms page, which is incorporated into these Terms by reference.

  • Subscriptions are sold and billed by Apple (App Store) or Google (Google Play), not directly by us.
  • Subscriptions auto-renew unless cancelled at least 24 hours before the end of the current period.
  • Cancelling during the free trial avoids any charge.
  • Refund policies follow Apple’s and Google’s respective rules.
  • We do not see your payment-card data.

8. Intellectual Property

All rights in the Lullacraft software, brand, logos, designs, documentation, and underlying technology are owned by the Operator or its licensors. Nothing in these Terms grants you any right to our trademarks or branding without our prior written permission. Third-party libraries and services used by the Service are governed by their own licenses.

9. Feedback

If you send us feedback, suggestions, or ideas, you grant us a perpetual, irrevocable, royalty-free, worldwide license to use them without obligation to you.

10. Disclaimer of Warranties

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE”, WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND ANY WARRANTIES ARISING FROM COURSE OF DEALING OR USAGE OF TRADE. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE, ERROR-FREE, OR THAT ANY AI-GENERATED GUIDANCE WILL BE ACCURATE OR SUITABLE.

Some jurisdictions do not allow the exclusion of certain warranties; in those jurisdictions the above disclaimers apply to the maximum extent permitted by law.

11. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL THE OPERATOR, ITS AFFILIATES, OR ITS LICENSORS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR EXEMPLARY DAMAGES, INCLUDING DAMAGES FOR LOST PROFITS, GOODWILL, USE, DATA, OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF THE SERVICE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

OUR TOTAL CUMULATIVE LIABILITY FOR ANY CLAIM ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE TOTAL FEES YOU PAID TO US (VIA APPLE OR GOOGLE) FOR THE SERVICE IN THE 12 MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) US$50.

Some jurisdictions do not allow the limitation of liability for certain damages; in those jurisdictions our liability is limited to the maximum extent permitted by law.

12. Indemnification

You agree to indemnify, defend, and hold harmless the Operator and its officers, employees, and agents from and against any claims, damages, losses, liabilities, costs, and expenses (including reasonable attorneys’ fees) arising out of or related to (a) your use of the Service, or (b) your violation of these Terms or applicable law.

13. Changes to These Terms

We may update these Terms from time to time. For material changes, we will update the Effective Date at the top of this document and notify you in-app before the change takes effect. Continued use of the Service after the Effective Date constitutes acceptance of the updated Terms.

14. Termination

You may stop using the Service and delete your account at any time from Settings. We may suspend or terminate your access if you breach these Terms, if required by law, or if continued operation becomes commercially unreasonable. Sections that by their nature should survive termination (including ownership, disclaimers, limitations of liability, indemnification, and dispute resolution) will survive.

15. Governing Law

These Terms are governed by the laws of the Hong Kong Special Administrative Region, without regard to its conflict-of-laws rules. The U.N. Convention on Contracts for the International Sale of Goods does not apply.

16. Dispute Resolution

16.1 Informal resolution

Before filing a formal dispute, please email legal@sanva.tk with a description of the issue so we can try to resolve it informally within 30 days.

16.2 Arbitration

Any dispute that cannot be resolved informally will be finally resolved by binding arbitration administered by the Hong Kong International Arbitration Centre (HKIAC) under its Administered Arbitration Rules in force at the time of submission. The seat of arbitration shall be Hong Kong; the arbitration shall be conducted by a sole arbitrator in English.

16.3 Class waiver

To the maximum extent permitted by law, you and we agree to bring claims against each other only in an individual capacity, not as part of any class or representative proceeding.

16.4 Local exceptions

If you are a consumer resident in a jurisdiction whose mandatory consumer-protection laws override the above (for example, certain EU member states), those laws apply to the extent they do, and the courts of your place of habitual residence retain jurisdiction.

17. Miscellaneous

  • Entire agreement — These Terms (together with the Privacy Policy, Subscription Terms, and EULA) constitute the entire agreement between you and us.
  • Severability — If any provision is held unenforceable, the remaining provisions remain in effect.
  • No waiver — Our failure to enforce a provision is not a waiver.
  • Assignment — You may not assign these Terms without our consent. We may assign them to an affiliate or a successor.
  • Force majeure — Neither party is liable for failure to perform due to events beyond reasonable control.
