It can be used for interactive blog posts and embedded animations etc as well.
It also has a built in animation editor / timeline.
Still a WIP, but it should be working well on Linux, Android and macOS. Give it a go if you want to support Anna's Archive.
However, there was one case that lead me to thinking about ditching grapheneos to this day. I installed Uber on my phone and I was able to successfully create an account and use it. When it came to booking a ride, the app crashed and I had to log in again. Once I did that, I was told that my account has been suspended for violating the terms of services. All I did to that point was creating an account and booking a ride. I was able to resolve the issue luckily after a few days and going back and fourth a couple of times with the Uber support, however, the risk of getting banned on any such platform is still risky, and thus I'm not sure if grapheneos is usable if you need to use such services.
So far I have experimented with NetShield from ProtonVPN and https://nextdns.io/ with varying results. There are also features baked into certain browsers like the cookie blocker with DuckDuckGo which works extremely well, and UnTrap for Safari on iOS which allows for heavy Youtube web customisation.
Also, shout out to Playlet on Roku. A privacy focused YouTube proxy for the TV which blocks ads and even can identify sponsors, filler and credit segments and allow you to skip these.
I am not involved in any of these projects, I just think they're cool.
