Your encryption key

When you enable sync, Vetroscope generates an encryption key — 16 characters in four groups, like AXKF-M29P-TNVL-8QWG. It’s what encrypts your sensitive data before it leaves each device, and what unlocks that data on a new one.

Caution

The in-app warning means exactly what it says: “If you lose it and all your devices, your cloud data cannot be recovered.” Not by support, not by anyone — that’s what makes the encryption real. Store the key in a password manager the moment you see it.

What it protects

App names, window titles, breakdown and project names, event labels, and similar content are encrypted with this key on your device before upload. The server — Vetroscope Cloud or your own Home Sync box — only ever stores the encrypted form. Your account password is separate and can be reset; the encryption key cannot, because no server has it.

Using it on a new device

Sign in on the new device and it shows “Encryption key required to sync” with an Unlock button. Enter your key; the device can then read and contribute to your synced data. Until you do, sync waits.

Viewing, verifying, regenerating

In Settings → Sync:

• Encryption key — view it again (to store it properly this time).
• Verify encryption key — check a key you have written down is the right one.
• Regenerating creates a fresh key and re-encrypts going forward — the option to reach for if you believe the key leaked.

If you’ve lost it

• Still signed in on at least one device? That device holds the key — open Settings → Sync → Encryption key and save it now.
• No devices left? The synced copy is unrecoverable. Your local data on any machine is unaffected — use Reset cloud data, generate a new key, and push again from the device that has your history.

One key covers all your sync targets — Cloud and Home Sync use the same one.
