1. Summary

Rendia is a compound interest calculator. It does not require an account. Scenarios and preferences are stored on your device. Rendia does not send that data to the developer’s servers.

If the app shows ads or offers in-app purchases, Google Play and Google AdMob may collect data under their own policies.

2. Data stored on your device

Rendia may store locally on your phone or tablet only:

• Calculation scenarios (principal, rates, terms, contributions, withdrawals, etc.).
• Names and tags you assign to scenarios.
• App preferences (language, theme, number format, currency).
• Backups you export or import yourself.

This data is used to calculate, display results, and save your scenario library. It is not sold or shared with Nebulaz Apps through an app-owned server.

Rendia does not request your name, address, phone number, contacts, precise location, camera, microphone, or banking credentials.

3. Data third parties may collect

When the app uses the internet, these services may process data:

Google AdMob (if the app shows ads):

• Android advertising ID (you can reset or limit it in system settings).
• Device and app technical data (e.g. model, OS version, language).
• Ad interaction (impressions, clicks).
• Diagnostics and performance data (e.g. crashes, load times).
• Data used to serve ads, measure campaigns, and prevent fraud.

Google Play (if you make in-app purchases):

• Google processes payment and transaction data.
• Rendia does not store card numbers or full payment details.

4. Exporting or sharing files

You may export results as PDF, CSV, Excel, or JSON and share them with other apps (email, cloud, etc.). This is voluntary. Recipients handle data under their own policies.

5. Advertising

If the app shows ads, they may be personalized or not depending on your region, Android settings, and your Google account privacy options.

In the European Economic Area, UK, and Switzerland, Google requires consent through a CMP compatible with IAB TCF where required by law.

You can limit personalized ads in: Android Settings → Google → Ads, and in your Google account privacy settings.

6. Security

Reasonable measures are used to protect data on the device. No system is 100% secure. Protect your device, screen lock, and exported files.

7. Retention and deletion

To delete local Rendia data you can:

• Delete scenarios inside the app.
• Go to Settings → Apps → Rendia → Storage → Clear data.
• Uninstall the app (local data is lost unless you backed it up).

Data processed by AdMob or Google Play is governed by their tools and policies. Use Play Console and your Google account to manage purchases or ad privacy.

8. Children

Rendia is not directed at children under 13. If you are a minor, use the app only with a parent or guardian’s permission.

9. Changes

This policy may be updated if features, ads, purchases, or Google Play requirements change. The date at the top shows the current version. Continued use after a change means you accept the published version, as allowed by law.
