About Tuta
Tuta is an open source, end to end encrypted email, calendar and contacts service for individuals and teams who need private communication to work across every device they own.
About Peergos
Peergos is a peer to peer secure file storage system, social network, and application protocol built in Java under AGPL 3.0. It lives in the IPFS, IPLD, and libp2p ecosystem and supports a private web where users control their data, decide where it is stored, and determine who can see it. The project addresses centralized services that can track users, expose personal data, and observe relationships or file contents without cryptographic access control.
