Hi Beatrice,

There is an option for cancellation:
If you purchased your subscription on iTunes: https://support.apple.com/en-il/HT202039
If you purchased your subscription on Andoid: https :// support. Google. Com/googleplay/answer/7018481? Co=GENIE. Platform%3DAndroid&hl=en
If you purchased your subscription on the OnlinePianist website: https://www.onlinepianist.com/account

There is an option in the settings page once you login to your account on the website. Alternatively, you can email OnlinePianist at onlinepianist.com with a request to cancel. The timing of the cancellation will be counted as the timing of your message to them if you choose the latter option.
