The short version: we collect no personal data. There are no accounts. The only data collection happens via Google AdMob, which serves ads to free users.

1. Data We Do Not Collect

No name, email, location, device identifiers, or behavioural data is collected by FiHub. No user profiles. Nothing to sell.

2. Data Stored on Your Device

Your calculator inputs (balance, rate, duration, contributions) and currency preference are stored locally via iOS UserDefaults. None of this leaves your device. Deleting the app deletes this data.

3. Advertising (AdMob)

Free users see ads served by Google AdMob. Google may collect device identifiers and usage data to serve relevant ads. You will be asked for permission via Apple's App Tracking Transparency prompt. Declining limits ad personalisation but does not affect app functionality.

For more, see Google's Privacy Policy.

4. Removing Ads

Purchase "Remove Ads" to disable all advertising and all AdMob data collection within the app.

5. Purchases

All payments processed by Apple via StoreKit. FiHub never sees your card details, billing address, or Apple ID.

6. Managing Subscriptions

Pro subscriptions are auto-renewable. Manage or cancel at any time via Settings → Apple ID → Subscriptions. Cancellation takes effect at the end of the current billing period.

7. Third-Party Services

• Google AdMob: Ad delivery for free users. Governed by Google's Privacy Policy.
• Apple StoreKit: Handles all payments. Governed by Apple's Privacy Policy.

8. Data Retention

FiHub holds no personal data. On-device data persists until you delete the app.
