Pubky.app requires zero personal data of any kind, you are a liar.

All apps require terms of service, including Nostr apps. In fact, relays should be providing them too. (some Terms protect users, all terms are to clarify the relationship between the provider and user)

The Pubky Ring app is open source and available for sideloading if you dont trust Google/Apple. You also can use pubky.app without Ring at all.
