Privacy

What this server keeps

The email address you give Stripe at checkout, the Stripe customer and subscription ids, a hash of your license key, and — once you activate — a machine id and an optional machine name you chose.

The license key itself is stored only as a hash. It is re-derived when you need it shown, and it is kept out of the server logs.

What it never sees

Card numbers. Those go directly to Stripe Checkout, which is also where invoices and refunds live. Stripe's privacy policy governs payment data.

Removal

Cancel in the billing portal and ask for deletion; the customer row, the license, and the machine binding go with it.
