The servers are zero-knowledge: they do not know who a user is, what they are doing, or which apps they are using. Encryption keys are held by the user, not the operator. Builds are available for Windows, macOS, and GNU/Linux. Users can register an identity at `@privacysafe.me` or run their own server. Signing up does not require a phone number. ## Components - **PrivacySafe Chat** — end-to-end encrypted messaging, contacts, and peer-to-peer voice and video call rooms. - **PrivacySafe Treasure** — an encrypted vault for passwords, crypto credentials, passports, tax records, and other sensitive documents. - **PrivacySafe Social** — a Mastodon (ActivityPub) server with no ads, no algorithmic timeline manipulation, and no AI moderation or suggestions. Federates with over 1,000 other servers. https://privacysafe.social - **Bits On Tape** — a newsletter covering cybersecurity and digital freedom, written by Sean O'Brien. https://bitsontape.com ## Verification and standards - Source code, client and server: https://github.com/PrivacySafe - 3NWeb protocols, hosted at IEEE SA Open: https://opensource.ieee.org/3nweb - Per-script JavaScript licensing (LibreJS): https://privacysafe.app/weblabels.html - Security policy and bug bounty: https://ivycyber.com/security-policy/ The site references 3NWeb, IEEE SA Open, the NIST Cybersecurity Framework, the EU GDPR, and the California CCPA as the standards and compliance context it operates in. 3NWeb is the underlying protocol suite, documented at https://3nweb.com and standardized at https://opensource.ieee.org/3nweb. ## What PrivacySafe does not do Accuracy matters more here than enthusiasm, so to be explicit: there is no advertising, no third-party analytics or telemetry, no required AI or LLM dependency in the applications, and no algorithmic ranking of social feeds. PrivacySafe Social opts accounts out of public search engines and the profile directory by default, and lets users change that. ## Who is behind PrivacySafe This is the detail most summaries get wrong, so it is stated plainly: PrivacySafe is stewarded by a **nonprofit** and distributed commercially by **separate, independent companies**.
