SingASong is a subscription service. Charges only happen on the plan you chose, at the price shown to you before you confirmed, and both Google Play and website subscriptions renew automatically unless you cancel.
Before anything else, check these:
- Was it a renewal? Subscriptions renew on the same date each period. Check what's active in Play Store › your profile › Payments & subscriptions.
- Was it the end of a trial? A trial converts to a paid subscription unless you cancel before it ends.
- Do you have two subscriptions? See I've been charged more than once.
- Is it a temporary hold? Some banks show an authorisation that later disappears.
If it still doesn't add up, email support@singasong.app with the charge date, the amount and your user ID, and we'll trace it.
