# Secure, Developer-Blind iCloud Backups

You want your data backed up in case you lose your phone, but you don't want to use a corporate server. Dot uses Apple's private iCloud containers.

## Backup your data seamlessly without ever giving us the keys.

- Zero-Knowledge Sync: We cannot see, access, or retrieve your backups.
- Seamless Device Transfer: Move easily from an old iPhone to a new one.
- Apple-Grade Encryption: Backed by Apple's robust security infrastructure.

## Developer Servers vs. Private iCloud

When you sync with Dot, the data goes directly to your personal Apple iCloud account. The developers have absolutely zero access to this private container.

## Frequently asked questions

### Can I backup my period app without giving data to the developer?
