Signal is a nonprofit that genuinely cannot read your messages or listen to your calls — the encryption is architectural, not a promise — but it requires a real phone number to register, is subject to US law, and its privacy policy is conspicuously sparse: it hasn't been substantively updated since 2018 and lacks the specific retention periods, GDPR rights, or DPO contact that more thorough policies provide.

The privacy story is split: strong on AI and content use, weaker on employer surveillance and ad-tech.
