Threema Web

End-to-end encrypted email from Switzerland. Zero access to your messages — even Proton can't read them. Open-source, audited, used by journalists and activists worldwide. Messages between Proton accounts are encrypted end to end automatically, without either side configuring anything.

End-to-end encrypted office suite — docs, spreadsheets, kanban, code pads. No account needed for guest use. Hosted in France, GDPR-native. The privacy-first Google Docs alternative.

End-to-end encrypted note-taking app. Zero-knowledge sync across devices. Open-source and audited. The Evernote/Notion alternative that genuinely can't read your notes. Notes are encrypted on the device before they ever sync, so the server stores ciphertext it cannot open.

End-to-end encrypted multi-device chat built on the Nostr protocol. Messages only decrypt on your device. Open-source, no server-side data, fully auditable. Keys never leave the browser, which means losing the device means losing the history — by design.

Share files up to 10GB with end-to-end encryption. Files are never stored permanently — they vanish after download or 24 hours. No account, no tracking. Faster than WeTransfer.

Matrix-based secure messaging — the open-source Slack/Discord alternative. Decentralized, self-hostable, end-to-end encrypted. Your messages are never locked in a corporate server. Because Matrix is federated, two people on different servers can talk without either joining the other's platform.
