A double charge in the app is usually one of:
- Two subscriptions (e.g. one in the app and one on our website — different billing systems).
- Two Google accounts on the same phone, each with its own subscription.
- A bank-side duplicate.
Check Google Play → Payments & subscriptions → Subscriptions for extra subscriptions and cancel the duplicate. For a Google Play double charge, request a refund through Google (see Refunds for Google Play purchases (Android)). Still stuck? Email support@whoisthis.io.
