To cancel your 0patch subscription (i.e, disable auto-renewal), do the following:
- Login to 0patch Central
- Open the Subscriptions tab on the Account page
- Locate your subscription and click on it to open its details
- Click on "CANCEL SUBSCRIPTION AT END TERM" and press "Confirm" on the confirmation popup
And don't worry: you can change your mind later and re-enable subscription renewal in the same place by clicking "AUTO-RENEW ON", or "RENEW FOR ONE TERM" to renew just one more time.
