Any device permission OpEvol asks for is used only on your device, to power the feature you’re using. Nothing is recorded or transmitted by us, except in content you choose to save or export. You can grant or revoke each permission at any time in your device’s Settings under OpEvol — if a feature isn’t working, that’s the first place to check.
Anything you export is written where you choose to save it — typically your photo library or Files. If an export doesn’t appear, confirm OpEvol has the matching access enabled in Settings.
OpEvol renders on the GPU, so sustained use will warm the device and draw on the battery. If things slow down, close other apps, and plug in when you’re running it for a long stretch.
If something looks wrong or doesn’t behave the way you expect, email us with your device model, your iOS version, and what you were doing when it happened. Feature requests are welcome too.
OpEvol does not collect, store, or transmit personal data. There are no accounts, no analytics, and no tracking. Full details are in our Privacy Policy.
OpEvol is free to download and offers optional paid features through an auto-renewable subscription. It’s handled by Apple through in-app purchase and tied to your Apple ID — there’s no separate account or login. The exact price and billing period are shown in the app before you confirm, and vary by region.
