The short version: TinniCalm has no accounts and no servers of its own. Your sounds, presets, settings and listening history stay on your device. We use Meta's advertising-measurement SDK to learn which ads lead to installs and purchases; it receives your device's advertising ID and app events, never your health information.
This policy covers TinniCalm for Android on Google Play. On iPhone the app is called Quiet Again: Tinnitus Relief and has its own privacy policy.
1. Information We Collect
We do not collect your name, email, phone number, location, health or medical information, audio, or anything you set up in the app. The only data that leaves your device is what the services in section 3 need to work:
- Purchase status (whether you have unlocked premium), handled by RevenueCat and Google Play
- Your device's advertising ID and app events (install, app open, purchase and its price), shared with Meta to measure our ads
2. Data Storage
All app data — including your sound preferences, custom presets, and settings — is stored exclusively on your device using local storage. This data never leaves your device and is not accessible to us or any third party.
3. Third-Party Services
- Google Play Billing — processes payments. We never see your payment details.
- RevenueCat — keeps track of whether your purchase is active, using an anonymous app user ID.
- Meta (Facebook) SDK — install and purchase events with the advertising ID, to measure and optimise our ads on Facebook and Instagram. Meta Privacy Policy.
TinniCalm versions up to 1.2.28 also sent install and purchase events with the advertising ID to TikTok, through its Business SDK, to measure our TikTok ads. Later versions do not start that SDK and send nothing to TikTok. TikTok Privacy Policy.
You can reset or delete your advertising ID at any time in your Android settings (Settings → Privacy → Ads), which stops these services from linking events to you.
4. Accounts & Authentication
TinniCalm does not require or offer user accounts. There is no sign-up, login, or authentication of any kind.
5. In-App Purchases
TinniCalm offers an optional one-time premium unlock. The transaction is processed entirely by Google Play. We do not receive, store, or have access to any payment information; the store's own privacy policy governs that transaction.
6. Children's Privacy
TinniCalm is not directed at children under 13, and we do not knowingly collect information from children.
7. International Users
The services in section 3 may process data outside your country under their own safeguards. You can ask us about your data or request deletion at contact@heldiglab.com.
8. Changes to This Policy
If we change this privacy policy, we will update the "Last updated" date at the top of this page.
