So browse in incognito mode?

That may mitigate the problem but it doesn't solve it especially when you didn't know it was occurring to begin with. The app is blatantly stealing your data. Would you accept that as a viable solution?

Always browse in incognito? Eff that, uninstall the offending app when you find out they are tracking everything you do online.

Browsing history is a very useful tool though.

Or just don't use proprietary garbage.

Doesn't Android block apps from reading each other's saved files?
