Account storage

This portal uses necessary, host-only cookies for sign-in, request protection and account setup. The encrypted sign-in cookie expires within one hour; a request-protection cookie expires after 30 minutes. No optional analytics or advertising cookies are used.

Single-use app handoff grants are encrypted and expire after 60 seconds; expired grants and request-limit records are removed every ten minutes. Product apps manage their own sessions and access.

Optional LEVRTEK marketing choices are stored in Cloudflare D1 with your provider account ID, email address, the exact consent text/version, source and time. Choices await email verification and expire after seven days if unconfirmed. Confirmed consent evidence is kept while active and for two years after withdrawal or account closure, then purged. Sign in to manage or withdraw the preference under Marketing email preference; product subscriptions remain separate.

Authentication is provided by Supabase; hosting, consent evidence and temporary handoff storage use Cloudflare. See the privacy notice for rights and contact details.
