DataCamp's mobile subscriptions are mobile-only, and DataCamp's browser subscriptions enable access to both mobile and browser versions.
If you wish to cancel your mobile subscription, you can reach out to Google Play or Apple, depending on your OS.
If your mobile purchase was made through Google Play, you can also reach out to support@datacamp.com for additional assistance (Apple has authority over all transactions within their app store).
