What does “no history” actually mean?
Pages you visit aren’t written to a history list, and what you type in the search box isn’t kept to be suggested back to you. Close all tabs and the cookies, cache and open sessions go too, so the next time you open the browser it starts from a clean page.
How does the ad blocker work?
It checks each request against a public blocklist of ad and tracker domains, refreshed every week, and stops the ones that match. The counter on the start page shows how many it stopped today.
Bookmarks, behind your lock
Some pages you do want to keep. Bookmarks are saved inside AppLock Master, so opening them takes the same PIN, pattern or fingerprint as your locked apps.
