Tips
- Test before adding protection. Run the plan on Unlocked first to make sure the allow list covers everything you need, then raise the protection once you are confident.
- Allow list entries take priority. If a site is both blocked and allowed, the allow list wins. FocusMe tells you when an entry is already on the other list and offers Move to allow list or Move to block list.
- Similarity protection (in the Advanced panel) stops near copies of blocked sites from being waved through on the allow list. If a legitimate allow entry is rejected with a Blocked: message, lower the level.
- Pair with app blocking. Blocking every website does not stop desktop apps that use the internet (Spotify, email clients and so on). Add those on the Applications tab if needed.
