Common questions

Permissions

Diff needs Camera access to show and record the effect, Microphone access to record audio with your videos, and add-only Photos access to save your exports. You can manage these any time in iOS Settings → Diff. If you decline the microphone, recordings are saved without audio.

Recording

Tap the record button to start and stop. When you stop, your processed video appears for preview, where you can Save it to Photos or Share it.

Where are my videos saved?

Saved videos go to your Photos library.

Privacy

Diff runs entirely on your device and collects no data. See the Privacy Policy for details.
