Cancellation
You can cancel at any time from your profile page. Cancel before the next renewal date and no further charges occur. After cancelling, paid features remain available until the end of the current period. If you purchased inside the iOS app, you can also cancel from your profile’s “Manage subscription” link or from Settings › Apple Account › Subscriptions on your iPhone.
Returns and refunds
Due to the nature of the service, no returns or pro-rated refunds are given after delivery. This does not limit any rights you have under applicable law. We do handle refunds individually for a double charge, and for any period the service was effectively unusable because of a failure on our side. Refunds for purchases made inside the iOS app are handled by Apple, under Apple’s terms.
System requirements
Latest versions of Safari / Chrome / Edge / Firefox, or the mekuru app for iOS
