Refund policy

Last updated 2 October 2026

Everything free on Hidden in π stays free. This page is about the paid extras, which are all digital.

The rule

Paid extras are digital and delivered straight away, so we don’t refund a purchase once you have downloaded or used it, unless it is faulty. If something you bought is faulty or never arrives, we’ll fix it or refund you in full.

This doesn’t affect any rights you have by law where you live.

Supporter pass

The pass renews once a year. Cancelling stops the next renewal; the pass keeps working until the end of the year you have paid for.

How to ask

Paddle, our reseller and merchant of record, handles payments and refunds. Find your order and ask for help at paddle.net, or contact us.

Purchases made inside the apps are refunded through Apple or Google, under their own rules.

Tips through Ko-fi are gifts rather than purchases; if you tipped by mistake, tell us.

Our contact address is being set up and will be listed here before the site launches.
