Where Does 1Blocker Store Rules on iPhone and Mac?
Where 1Blocker keeps blocklists, rules and settings on iPhone and Mac for backup and moves.
Last updated
1Blocker keeps custom rules and settings in its app container with optional iCloud sync, while stock blocklists ship inside the app bundle. Safari loads compiled rules from the container on every launch.
Custom rules are the irreplaceable half; stock lists reinstall themselves. Sync carries customs between signed in devices. Reinstalls without sync wipe custom rules for good, so verify sync before removing the app.
