How We Protect Your Browser Data

Lumensic enforces strict browser security flags on all server-issued cookies. Sensitive session identifiers are configured with HttpOnly, Secure, and SameSite=Lax attributes to prevent unauthorized cross-site access and JavaScript injection vulnerabilities.

  • Zero Third-Party Advertising: Lumensic does not sell user tracking cookies to third-party ad networks or data brokers.
  • Local Storage Encryption: Resume draft AST cache items stored in local storage are scoped strictly to your authenticated session token.
  • Instant Revocation: You can clear your consent or delete all stored Lumensic cookies anytime via the preference manager or your browser controls.
