Privacy-first Apps — End-to-end Encryption, Zero Knowledge
Apps that can't see your data even if they wanted to.
Privacy-first applications using end-to-end encryption, passkeys, and zero-knowledge architecture. Password management, passwordless sign-in, and time-locked encrypted messages — all on the Internet Computer.
- Cloak by Cloakencrypt — Encrypted credential storage where passwords are encrypted on your device before they ever leave it.
- Internet Identity by DFINITY Foundation — Passwordless sign-in for the Internet Computer — a passkey or a provider you already use, with no tracking and no personal data shared.
- capsl by Christopher Harrison — Write a message. Seal it. Open it in the future.
Frequently asked questions
- What is VetKeys, and why does it matter?
- VetKeys (Verifiable Encrypted Threshold Keys) is the Internet Computer's threshold key system. The encryption key for your data is split across nodes; no single party (including the developer) ever sees the full key. It's the foundation of true zero-knowledge apps.
- Are these apps end-to-end encrypted?
- Where it matters, yes. Cloak encrypts your vault on your device before upload. Capsl uses time-locked encryption. Internet Identity never reveals personal data to apps.
- Can the developer or DFINITY read my data?
- No, for apps that use VetKeys or end-to-end encryption properly (Cloak, Capsl). The Internet Computer subnets running the canisters never see plaintext.
- How do I verify privacy claims?
- Many listed apps are open source, so you can read the code, and Cloak and Internet Identity have public security audits. We link an app's source repository on its detail page wherever we could verify one, but we don't host audit reports, so check the app's own site for those.
