In plain English — Signal

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.

In plain English — Proton

Proton collects as little as technically possible, can't read your encrypted content even if asked, is governed by strict Swiss law, and gives you real control — the rare case where the privacy policy matches the privacy pitch.
