Payroll files

The calculator reads your CSV files inside your browser tab and does all calculations there. The files and results are never sent to Box12TT or anyone else. Closing the tab discards them.

License keys

When you activate a season pass, the key you paste is sent to our license check, which asks our payment provider, Polar, whether it is valid. The key is then stored in your browser's local storage so you don't have to paste it again.

Purchases

Payments are handled by Polar (polar.sh) as merchant of record. Polar receives your name, email and payment details under its own privacy policy. We receive your email and order details so we can provide support and refunds.

Analytics

We count page views with cookie-free, aggregate analytics. We do not use advertising trackers.
