How the encryption works
The key hierarchy, and an explicit list of what the server can still see.
What is encrypted
Nothing in that right-hand column is a secret we are keeping — it is published in the
security page because a threat model that lists only strengths is marketing.
What you can do with it
- Upload files up to 5 GB each, encrypted in 4 MiB chunks as they leave the browser.
- Organise into folders, rename, move, and recover from a trash that you empty yourself.
- Preview images, video, audio and text in the browser without downloading.
- Keep version history — 10 versions on Pro, 30 on Max, with restore.
- Share with a person by email address, as a viewer, commenter or editor.
- Share by link, optionally with a password, an expiry date and a download limit.
- Revoke either kind of access at any time.
