Brazil's authoritarian age verification law became active this month. It won't be implemented by GrapheneOS. Complying would require integrating a mandatory process for each user where a third party service checks government identification and confirms a match using the camera.
It doesn't stop there. It would require keeping data for auditing and providing a token for connecting age verification checks by apps and websites to the data. The law is a privacy disaster and exposes minors to being exploited by leaking their age bracket to apps and websites.
