Terms of Service

Effective date: August 11, 2026

1. The service

Sentryn is a mobile application by Dawnward Labs ("we"). It runs entirely on your device; there is no account and no hosted service. These terms cover your use of the app and this website.

2. Eligibility

Sentryn is not directed to minors, and we do not knowingly collect information from them. To take on a paid subscription you must be at least 18, or have the consent of a parent or legal guardian where the age of majority differs. Indian law treats individuals under 18 as minors; where required, a parent or guardian must accept these terms on the user's behalf.

3. Trial

New installs include a 7-day trial with full functionality, no payment details required. After it ends, creating new commitments — and exporting your history as a CSV file — requires a subscription; reviewing and reflecting on your existing data in the app, and making an encrypted backup of it, stay available.

4. Subscription

The subscription is billed yearly through Google Play at the price shown before purchase ($19.99/year during the launch window; $39.99/year after). Billing is handled by Google Play, and subscription entitlements are managed by RevenueCat, our subscription-management provider (see RevenueCat's privacy policy); we never receive or store your payment details. Cancellation, refunds, and renewal are handled through Google Play under Google's terms.

5. Your data

Your data lives on your device and is yours. We have no copy and cannot restore it — backups are your responsibility, using the encrypted export in the app. A lost backup passphrase cannot be recovered by anyone, including us.

6. Intellectual property

Sentryn, its name, design, and content are the property of Dawnward Labs and are protected by applicable intellectual-property laws. We grant you a personal, non-exclusive, non-transferable, revocable licence to use the app for its intended purpose. You may not copy, modify, reverse-engineer, or redistribute the app except to the extent the law permits.

7. Acceptable use

Don't attempt to circumvent the subscription, redistribute the app, or use it in violation of applicable law.

8. Disclaimer

Sentryn is provided "as is", without warranties of any kind. To the maximum extent permitted by law, Dawnward Labs is not liable for indirect or consequential damages, including missed reminders — device manufacturers' battery management can delay or suppress notifications outside our control.

9. Governing law

These terms are governed by the laws of India. Disputes are subject to the courts of Pune, Maharashtra.

10. Changes

We may update these terms; material changes will be posted here with an updated effective date.
