Accessibility Permission, Clearly Explained
Universal Undo uses Android Accessibility only to detect text changes in focused input fields so undo/redo can work system-wide.
- Used only for text-change events required for undo history.
- No Internet permission in app manifest, so text is not uploaded.
- Password and sensitive fields are ignored automatically.
- You can exclude apps anytime with blacklist controls.

Frequently Asked Questions
Does Universal Undo work in all Android apps?
It works in most apps with editable text fields, including messaging, notes, and email apps.
Why is Accessibility permission required?
Android requires Accessibility events for cross-app text change detection. That is how undo/redo can work globally.
Is my text uploaded to servers?
No. The app does not request Internet permission, and text history stays on your phone.
Can I disable tracking in specific apps?
Yes. Use app blacklist controls to exclude any app you do not want monitored.
How quickly can I recover text after deleting it?
Recovery is immediate inside active sessions. Timeline restore helps recover earlier states before app or device reset.
