Don’t use tiktok, it’s really bad for your privacy, a super addictive app. The main point is to just watch recommended videos rather than searching, which makes it more like TV. It also censors content, and most of what you’ll find there is actually bad. The app is proprietary, therefore making a different client is hard. (Newpipe for example doesn’t recommend videos to you that aren’t in your list, but tiktok’s recommendation algorithm can’t be done this way. Anyway, better not to get started, it will just waste your time.
Yes but it’s not good enough for privacy for many users, as it requires a phone number to set up an account.
