if you are worried about someone grabbing your phone while you are browsing something,
you cant protect your history like this.
(or atleast i am unaware of such a feature in vanadium, maybe another browser does, but i never saw it personally)
You can use private spaces tho, and use the browser inside it. Then you would use your fingerprint to unlock private spaces -> use the browser -> lock it when done.
(or profiles, but private spaces (or rather the one private space one can setup) is more convenient)
(edit: i feel like there should be an option to disable browsing history, like always incognito, but i cant find it)
