Privacy Policy

Zilonex Unit Converter is a free offline unit conversion app built and published by Zilonex. This privacy policy explains what data the app collects, stores, and uses.

The short version: we collect nothing. The app works entirely on your device. No data is ever sent to our servers or any third party.

Zilonex Unit Converter does not require you to create an account, log in, or provide any personal information to use the app. There is no registration, no email, and no profile.

The app saves the following data locally on your device only using AsyncStorage:

• ✓Conversion history — Your recent conversions (up to 5 per category) so you can pick up where you left off.
• ✓Favourites — Unit pairs you have saved as favourites for quick access.
• ✓Theme preference — Your chosen display theme (Light, Dark, or System).

This data never leaves your device. It is not transmitted, synced, backed up to our servers, or shared with any third party.

We do not collect, store, or process any of the following:

• ✕Your name, email address, or any personal identifiers
• ✕Your location or GPS data
• ✕Device identifiers, advertising IDs, or IP addresses
• ✕Usage analytics or crash reports
• ✕Camera, microphone, or media access
• ✕Contacts, calendar, or any other device data

Zilonex Unit Converter is designed to work 100% offline. The app does not request or require an internet connection. All unit conversions are computed locally on your device.

The app's Android manifest explicitly blocks internet permission.

Zilonex Unit Converter does not integrate any third-party SDKs, analytics tools, advertising networks, or tracking services. There are no ads in the app.

This app does not collect any data from users of any age. It is safe for use by children. We do not knowingly collect personal information from anyone, including children under 13.

Since all data is stored locally on your device, you can delete it at any time:

• →Open the app → Settings → Clear History to delete conversion history.
• →Uninstalling the app permanently removes all locally stored data.

If we update this privacy policy, we will update the effective date at the top of this page. Since we do not collect your contact information, we cannot notify you directly — please check this page periodically if you wish to stay informed.

If you have any questions about this privacy policy or the app, please contact us:
