UnitFlow Privacy Policy

Last updated: June 16, 2026

UnitFlow ("the App") is a unit and currency converter for Android. This policy explains what data the App handles and, just as importantly, what it does not.

1. Data we do not collect

UnitFlow does not require an account, and does not collect, store, or transmit any personally identifiable information (name, email, phone number, location, contacts, photos, etc.). The App contains no analytics SDKs, advertising SDKs, or crash-reporting SDKs.

2. Data stored on your device

The App stores the following data locally on your device only, using Android's DataStore. This data is never transmitted to us or to any third party:

• Your selected display language (English or Thai)
• The most recently fetched currency exchange rates, cached for offline use

Uninstalling the App removes this data.

3. Third-party services

To show up-to-date currency exchange rates, the App connects directly to the European Central Bank's public reference rate feed (ecb.europa.eu). This request does not include any information that identifies you personally — it simply downloads the current published rates. No other third-party service is contacted by the App.

4. Permissions

The App requests only the INTERNET permission, used exclusively to download the exchange-rate feed described above. The App does not request access to your camera, microphone, location, contacts, storage, or any other sensitive permission.

5. Children's privacy

The App does not knowingly collect any data from anyone, including children, because it does not collect personal data from any user.

6. Changes to this policy

If this policy changes, the updated version will be posted at this same address with a revised "Last updated" date.

7. Contact
