1. Data We Collect

We collect minimal data necessary for service operation:

  • Authentication metadata (via Google Auth)
  • Encrypted secret blobs (which we cannot decrypt)
  • Usage metrics and billing information
  • Error logs (anonymized)

🔒 ZERO KNOWLEDGE GUARANTEE

We cannot decrypt your secrets. We do not store your Master Password or Private Keys in any form. Your data is encrypted client-side before it reaches our servers.

2. How We Use Your Data

  • To provide and maintain our service
  • To process billing and payments
  • To send important service updates
  • To improve our product (via anonymized analytics)

3. Data Sharing

We never sell your data. We only share data with:

  • Payment processors (Stripe) - only billing info
  • Infrastructure providers (for hosting encrypted data)
  • Law enforcement (only with valid legal orders, and only metadata)

4. Your Rights

You have the right to:

  • Access your data at any time
  • Export all your encrypted secrets
  • Delete your account and all associated data
  • Opt out of marketing communications
