Current site
The current static site does not require an account, store calculator inputs or use advertising cookies. Analytics and advertising scripts are omitted unless configured later.
Accounts
When membership is activated, the service stores an email address, plan, Stripe customer and subscription identifiers, hashed API keys, opaque sessions and daily usage counts. Magic-link and session records expire. Raw API keys are shown once and are not stored.
Service providers
Cloudflare hosts the site, account database and automated form verification. Resend delivers transactional email. Stripe handles checkout, subscriptions and billing records. The site does not receive full payment card numbers.
Deletion
The account page can cancel an active subscription and delete the user, sessions and API keys. Stripe may retain payment records that it is legally required to keep.
Third-party links
Source links lead to external sites with their own privacy practices.
