Your keys.
Not ours.
Automated, end-to-end encrypted backup for Mac and Windows. Files are encrypted on your device with AES-256-GCM before they ever leave — so we store data we genuinely cannot read.

Encryption you don't have to trust us on
Your passphrase derives an encryption key on your device. It's stored in the Secure Enclave (macOS) or Windows Hello — never transmitted, never on our servers. If we're breached, attackers get ciphertext and nothing else.

One backup, ten clouds
Bring your own storage. Back up to several providers at once — a backup succeeds if any destination succeeds.
Fast, frugal, and hands-off
Incremental transfer
After the first run, only changed files move — up to 94% faster and a fraction of the bandwidth.
Block-level dedup
Content-defined chunking stores identical blocks once, across files and backups — 40–70% savings.
Compression
LZFSE and GZip shrink data another 30–70% before it leaves your machine.
Versioning & retention
Keep point-in-time versions with retention policies and restore-anywhere recovery.
Smart scheduling
Daily, weekly or custom schedules that sync across all your devices.
Connection-aware
Auto-throttles on metered or cellular, respects peak hours, and adapts to network quality.
Mac and Windows. Full parity.
Native apps on both platforms with the same features, the same encryption, and cross-device restore — start a backup on your Mac, recover it on your PC.
