Account Information

To provide subscription services, we collect and store:

  • Email address
  • Hashed password (using bcrypt)
  • Name (optional)
  • Subscription status and billing information
  • Feature-set version entitlements (e.g. Lifetime Beta access to the 2025 validator suite)

This information is used solely for account management, determining which validator features you can access, and service delivery. We do not share it with third parties except payment processors (Stripe).

Lifetime Beta Communications

If you purchase the Lifetime Beta licence, we will record that entitlement and may contact you about maintenance updates to the covered validator set, opportunities to provide feedback, or optional upgrade paths when future validator families launch. These messages are limited to product notices relevant to your licence and you can opt out at any time.
