Security & Privacy
Your data is yours. Full stop.
A backup app earns its keep on trust. Here's exactly how Back That Data Up protects yours, no fine print.
Local-first by design
Backing up your Mac's drives happens entirely on your Mac. There's no account, no server that holds your local backups, and nothing of yours on our infrastructure. We can't see your files because they never come to us.
Encryption you control
Drives encrypt with APFS, unlocked by Touch ID or a hardware security key, the keys live in your Mac's Secure Enclave or your physical key, never with us. Cloud Vault encrypts every file before it uploads; your cloud stores ciphertext only.
No telemetry
BTDU doesn't phone home with analytics about what you back up. The activity log that records your runs is stored only on your Mac, and never shared with anyone, including us.
We only handle licensing
The one thing that touches our servers is verifying your purchase and delivering your key, and that never involves your files. Payments are processed by our merchant of record; we don't store card details.
Catches attacks in the act
BTDU profiles every backup as it runs and pauses the instant it spots the fingerprints of an attack, such as ransomware, so a compromised file can never overwrite the clean snapshots you'd restore from.
You decide what's protected
Exclude any file, folder, or file type, and choose exactly which folders sync to the cloud. Nothing you don't pick is ever copied or uploaded, privacy by what you leave out, not just how it's encrypted.
Real encryption has real consequences
If you lose your key, we can't get it back
Encryption we could bypass isn't encryption. If you lose your Cloud Vault key or your drive's unlock method, we can't recover your data, and neither can anyone else. That's the deal that keeps your files truly private. Keep your recovery key somewhere safe.
Private by default. Yours by design.
