What we handle

Your FPL Team ID. When you enter it, our server fetches your public team from the FPL API and keeps it in memory for about two minutes, so repeat requests are fast. We do not store it in a database. Your browser remembers the last ID you used (local storage) so you do not have to type it again. You can clear that in your browser.

The calculation runs on your own device. Your team is not sent anywhere else.

Deadline reminders (only if you sign up). If you ask for reminder emails, we store your email address, your FPL Team ID and the time you confirmed. We use them only to email your planned transfers before each FPL deadline. You confirm by clicking a link (double opt-in), and every email has an unsubscribe link that deletes your address at once. The emails are sent through Resend (Resend Inc., USA, under the EU Standard Contractual Clauses). Legal basis: your consent.

Payments. Pro is sold through Stripe (Link), which acts as merchant of record and handles payment details and VAT. We never see your card. We keep the Stripe customer reference that your Pro key is made from.

Visitor statistics come from Plausible Analytics (EU-hosted, no cookies, no personal data).

Sub-processors: Railway (hosting, EU West), Cloudflare (DNS and network), Plausible (statistics), Stripe (payments), Resend (reminder emails).

No accounts, no passwords

We never ask for your FPL login.

Your rights

Write to contact@addonnordic.dk with any question about your data. You can complain to Datatilsynet (the Danish Data Protection Agency).
