How do I cancel my subscription?
Cancel through Google Play, where your subscription is billed. You can do it from the Play Store app on your phone (Menu → Subscriptions) or on the web at play.google.com/store/account/subscriptions. Tapping Manage plan in Lonzo takes you to the same place from either the app or the web app. Cancelling stops the next renewal; you keep access through the end of the current period.
After the period ends the account has no product access until you subscribe again — there is no free plan to fall back to. Your data is retained, not deleted, so re-subscribing restores your account. Cancelling doesn't cut short the access or the usage allowance you already have for the current period. If you only want to spend less, switching from Lonzo Assistant to Lonzo Agenda keeps the product running. See the Subscription & Billing Terms for the details.
