Privacy Policy
Last updated: February 27, 2025
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 iPhone or iPad using Apple's built-in frameworks (CoreImage, AVFoundation, PDFKit, and others). Your files are:
- Read from where you selected them (Photos, 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 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: To verify your purchase status and process the one-time in-app purchase. This communication is between your device and Apple's servers, 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 third-party SDKs, analytics services, crash reporters, ad networks, or tracking tools. The app is built entirely with Apple's native frameworks.
Trial and Purchase Data
When you first open Convexy, a trial start date is saved locally on your device in the iOS Keychain. 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 Apple's StoreKit framework 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.
