Privacy Policy

Mind in Chain / Tripdivefly

Last updated: 13 September 2026

1. Data Controller

The data controller for the Mind in Chain application is Hugo Ruiz Ogando (Tripdivefly).

2. Data stored on your device

The application stores data only on your device (browser or app local storage):

• Name or nickname that you choose when starting (optional), to display on app screens.
• App progress: unlocked blocks and current block, so you don't lose your progress.
• App version viewed, to check for updates.
• Purchase / unlock flags for in-app purchases (store-specific), stored locally.

Nickname and progress stay on your device unless you clear app data or uninstall. They are not used for advertising.

On Android, if device backup is enabled, this local data may be included in your system backup according to your device settings.

3. Usage telemetry (our servers)

To operate and improve the service, the app may send limited technical usage events from our script humano.js to our APIs on tripdiveflyes.com and mind.tripdivefly.com (for example: app open, screen/language path, training progress events).

Those events include a pseudonymous session ID created in the app, coarse device class derived from the User-Agent, and technical request metadata. Our server may read your IP address, store it in masked form (for example a.b.c.x), and derive an approximate country/city for operational statistics.

We do not require accounts or login for the training content, we do not show ads, and we do not sell personal data.

4. Third-party services and links

The app loads content mainly from tripdiveflyes.com. For technical reasons it may also contact third-party services. Those providers process network requests (typically IP address and User-Agent) under their own policies:

• ipwho.is — used by our backend (and optionally by the language hub) to obtain approximate country/city from IP for language suggestion and operational stats.
• Google Fonts (fonts.googleapis.com / fonts.gstatic.com) — typography.
• CDN / image hosts — for example assets.zyrosite.com (backgrounds) and flagcdn.com (language flags).

In-app purchases (when available) are processed by the store (Google Play, AppGallery, Microsoft Store, ONE Store, etc.). Payment and account data for those purchases are handled by the store under its own privacy policy; we receive purchase/entitlement status needed to unlock content.

The app may open store or external pages (for example book purchase links) in your browser. Those sites have their own privacy policies.

5. What we do not do

We do not sell personal data. We do not use advertising SDKs or advertising IDs in the Mind in Chain apps. We do not collect email addresses inside the training app for marketing.

6. Changes

Any relevant change to this policy will be reflected on this page, with an update to the date indicated at the beginning.

7. Contact

For questions about privacy or this policy, you can contact the developer email associated with the app listing.
