I was planning to wait and see what Boost has to offer before deciding if I should pay $20 to remove ads on Sync, but seeing this has convinced me to delete the app for good. Even Reddit isn’t half as bad as Sync when it comes to trackers and shady ads.
If I click a link in Sync, and I have an account for that site, I log in for my view preferences, and to save something to read later.
You also don’t need to log in for a site to track who’s visiting it. It’s like website 101 now, that every site tracks how anyone interacts with it.
