Security

Built so your work stays yours

Security is not a page we wrote once. It is the shape of the product: private storage, database-enforced permissions, revocable links and keys, and no data resale — ever.

  • Encrypted end to end of the pipe

    Every byte travels over TLS 1.3 and is written to encrypted storage at rest. Nothing is served from an unencrypted origin.

  • Row-level access control

    Your files, chats, keys and receipts are locked to your account at the database layer, not just in the interface. A leaked link cannot read another account's rows.

  • Private by default

    New uploads land in a private bucket. A file becomes reachable only when you explicitly create a share link, and you can revoke it instantly.

  • Hardened partner API

    Partner requests are authenticated with a key id plus a hashed secret and a short-lived authorization code, scoped per key and rate limited per plan.

  • Auditable activity

    Key usage, API requests, payments and account changes are logged so you can see exactly what happened and when.

  • Email privacy

    We never expose one user's email address to another. Where an address must be shown it is masked, and administrator addresses are never displayed at all.

Account protection

What you control from inside your account.

  • Strong password enforcement with breached-password checking
  • Password reset links that expire and can only be used once
  • Sign in with Google, or email and password — your choice
  • Share links with expiry dates and optional passwords
  • One-click revocation for any share link or API key
  • Full export and permanent deletion of your data on request
