There is no free trial. Instead, every purchase, single apps and All Apps alike, can be refunded within 15 days, with no questions asked.
How to ask
Write to us from the email address you bought with. Polar sends the money back to the card you paid with.
After a refund
The license is ended, and the app returns to its unlicensed state on your computers.
50% back
The 50% back program is separate from the refund window and has its own rules.
