Currently autorenewal is enabled by an automatic Paypal payment from your side to us, upon which we renew your licence. This means that only you can enable or disable autorenewal.
To do so, please login at Paypal and disable your automatic payment to the PocketFMS Foundation there. Your subscription will then automatically expire and will not be renewed.
You will get an e-mail alert from us when your subscription is about to expire, with a reminder to renew.
