# Can I stop the app from uploading files over mobile data?

On Android, yes. Open Settings > ID & Sync and turn on "Files on wifi only". Your notes keep syncing on any connection, because text is tiny. Only images and attachments wait, and they go up the moment wifi comes back rather than sitting out the next retry.

Android is where the switch lives, because Android is the one platform whose app view reports wifi against cellular reliably, and a switch that guesses is worse than no switch. On a metered connection anywhere else, ["Pause sync"](https://privacynotes.app/help/pause-sync/) does the same job with a bigger hammer and works everywhere.
