Terms
Generating, playing and sharing progressions is free. Chord progressions are not protected by copyright, so what you make is yours to use, including commercially.
Pro is sold by Lemon Squeezy as merchant of record; its terms of sale, refunds and tax handling apply to your purchase. Subscriptions renew until cancelled and can be cancelled any time from your Lemon Squeezy account; Pro stays active until the end of the paid period. A lifetime licence covers Pro features for as long as the service runs.
The service is provided as is. Contact: [add your contact email before launch].
