Cirrux Backup

Your Gmail, backed up
and encrypted

What if Google locked you out tomorrow? Cirrux Backup keeps a secure, encrypted copy of your inbox on European servers. You own your data—always accessible, completely private.

Why backup matters

Your data independence starts here

Peace of mind

Your emails are safe, even if something happens to your Google account. Sleep better knowing your data is protected.

You hold the keys

Only you can decrypt your emails. Not Google, not us—no one but you. Your private key stays on your device.

European servers

Your data lives on secure servers in Germany, protected by GDPR. No US jurisdiction, no surveillance overreach.
