Just don’t. If you want TikTok content then look for YouTube compilations or reposts (do shorts work on Piped?)
TikTok is one of the most privacy-invasive apps ever created, and that’s before even considering the data they get from watching what videos you watch/like. They harvest literally everything they can from your phone.
I guess if you run it in a VM on an Android emulator with a VPN and strict vlan/firewall rules using an email address you created specifically for it, but even then it doesn’t seem worth it.
