Security you can rely on

Your files are yours. We design every part of Cumulo to keep them that way.

Encryption everywhere

Files are encrypted while they travel between your device and our servers, and again while they are stored.

Two‑factor sign‑in

Protect your account with an authenticator app or a hardware key. We will alert you about new sign‑ins.

Reliable infrastructure

Data is replicated across multiple data centres. Backups are tested regularly so that restores are boring.

You stay in control

Review connected devices, revoke shared links, and delete your data whenever you like.
