Zero knowledge

Document and file contents are encrypted on your device before they sync. The service stores ciphertext and wrapped keys, not plaintext content keys. The app derives who can receive keys from signed access records it verifies, not from server-provided lists.

Zero onboarding

On first open, Tearleads creates your identity keys on your device and, once you're online, registers their public keys with the service. Those keys sign you in, so there's no account form.

Recovery
24-word recovery phrase

Save your 24-word recovery phrase from Identity Manager when you're ready and keep it private: it restores your identity on any device. Web checkout for paid plans asks only for a billing email.

How it works

What's in Tearleads

Everything lives in one folder tree in Explorer.

All features

  • Notes

    Plain-text notes with attached files and image previews.

  • Contacts

    Names, nicknames, and profile photos. Add someone's identity link to link a contact to that person's identity.

  • Files

    Import images, PDFs, audio, and video into nested folders, download them again, and recover items from Trash.

  • Records

    Structured records such as driver's licenses and passports, each with its own fields and images.

  • Offline first

    Edits save on your device first and sync when you're back online.

  • Backups

    Export a password-protected backup file and restore from it.

How it works

  1. Open Tearleads

    Use the web app, or install the desktop app for macOS or Linux. Your identity is ready the moment it opens.

  2. Work on your device

    Notes, contacts, and files are stored encrypted on your device and stay editable offline. Export a password-protected backup anytime.

  3. Sync and share

    Your personal organization gets a 7-day free sync trial when the app registers your identity. After that, paid plans keep end-to-end encrypted sync across your devices; Team plans add folder sharing with your organization's users and groups.

Private by design

Your content is encrypted before it leaves your device, and access is backed by signatures the app checks itself.

How the security model works

  • Encrypted on your device

    Document and file contents, organization names, and custom group names are encrypted on your device before they sync. The service stores ciphertext and wrapped keys, not plaintext content keys.

    Details

  • Verified sharing

    The app decides who can receive a folder's keys from signed access records and group policies it verifies itself, not from the server's membership rows.

    Details

  • Atomic key rotation

    Removing group members rotates the group key and the affected folder keys in one atomic update.

    Details

  • Encrypted at rest

    Local data is encrypted under keys protected by a host wrapping key. You can add a PIN lock.

    Details

Post-quantum Public-key operations in the Tearleads keying protocol use ML-KEM-1024 for key delivery and ML-DSA-87 for signatures (NIST FIPS 203 and 204). Synced document and file contents are encrypted with AES-256-GCM.

Pricing

Free on your device. Paid plans add sync for one organization, priced by member capacity rather than per member.
