Privacy Policy

Last updated: April 15, 2026

The short version: Convexy does not collect, store, transmit, or share any of your data. Your files never leave your device. There is no server. There is no analytics. There is nothing to hack.

What Data We Collect

None. Convexy does not collect any personal data, usage data, analytics, diagnostics, or telemetry of any kind.

How Your Files Are Processed

All file conversions happen entirely on your device using the operating system's built-in frameworks (CoreImage / AVFoundation / PDFKit on iOS; BitmapFactory / Media3 / PDFBox on Android). Your files are:

Read from where you selected them (Photos / Gallery, Files, or another app)
Copied to a temporary working directory on your device
Converted locally using on-device processing
Saved to the location you choose (Photos / Gallery, or Files)
Temporary copies are deleted immediately after conversion

At no point are your files uploaded to any server, cloud service, or third party. The app works fully offline.

Network Access

Convexy makes no network requests except for:

Apple StoreKit (iOS) / Google Play Billing (Android): To verify your purchase status and process the one-time in-app purchase. This communication is between your device and the App Store / Google Play, handled entirely by the operating system. Convexy has no server of its own.

The app functions fully without an internet connection. You can enable Airplane Mode and every feature works normally (except purchasing).

Accounts and Authentication

Convexy does not require or support user accounts, logins, email addresses, or any form of authentication. You open the app and use it.

Third-Party Services

Convexy uses no analytics services, crash reporters, ad networks, or tracking tools. The app uses only the platform's native frameworks plus a small number of open-source libraries for specific conversions (e.g., Media3, PDFBox, FFmpegKit on Android). None of these contact any server.

Trial and Purchase Data

When you first open Convexy, a trial start date is saved locally on your device (in the iOS Keychain on iOS, or in local preferences with Auto Backup on Android). This date is used solely to calculate how many days remain in your 14-day free trial. It is never transmitted anywhere.

Purchase status is managed by the platform's StoreKit (iOS) or Google Play Billing (Android) on your device. Convexy does not operate any server to track purchases.

Children's Privacy

Convexy does not collect data from anyone, including children. The app contains no social features, no user-generated content, and no communication capabilities.

Changes to This Policy

If this policy changes, the updated version will be posted at this URL with a new "Last updated" date. Since Convexy collects no data, meaningful changes are unlikely.
