My Studio Tracker is one plan: the first month free, then £9.99 a month, cancel any time. Everything about it is on the Billing page, which stays open even when the rest of the app is locked.
Your free month
Every new account gets 30 days free with no card. The Billing page shows the end date, and a banner appears in the app during the last week. When the free month ends without a subscription the app locks: you are sent to Billing whenever you open it. Nothing is deleted; your students' pay links and calendar feeds keep working, and everything is there when you subscribe.
Subscribe
Press Subscribe, £9.99 a month. You enter your card on Stripe's checkout page (this is My Studio Tracker's own Stripe account, separate from any Stripe account you connect for your students' payments). If you subscribe during your free month, the card is not charged until the free month ends. Payment is taken monthly from then on, on the same date each month.
Change your card or see past payments
Manage subscription opens Stripe's billing portal, where you can change the card, see and download past payments and receipts, update your billing address, or cancel. It is the same portal regardless of how you signed in to StudioTracker.
If a payment fails
If a monthly payment fails (an expired card, an insufficient balance), the app shows Your last payment failed and Billing offers Update your card. Stripe retries the payment for a few days; if none succeeds the subscription is cancelled and the app locks until you subscribe again. Updating the card in time keeps everything running.
Cancel
Cancel from Manage subscription. Billing stops immediately, you keep access to the end of the month you have paid for, and the Billing page shows the date. After that the app locks, but as with the free month nothing is deleted: pay links keep working so students can settle up, and subscribing again picks up where you left off. To have your data removed as well, see Delete your account.
Vouchers
If you have a voucher code, enter it in Have a voucher? on Billing. It gives free access until a date shown on the page, with no card needed. When it runs out, subscribe as normal.
Refer a teacher
Your Billing page has a personal link. When another teacher creates an account through it, they get two free months instead of one, and you get a month: added to your free time if you have not subscribed yet, or taken off your next payment if you have. Up to twelve months can be earned. The page lists who joined and which month it made free. The teacher who joined can see on their own Billing page that the extra month came from your referral. The dashboard offers the same link once your first payment lands, and it is repeated in the monthly email that sums up what you were paid; both can be ignored or, for the dashboard card, hidden.
My Studio Tracker itself emails you a handful of times: a few short set-up tips during your free month, a reminder before it ends, and a monthly summary of what you collected. A tip whose job you have already done is never sent, and every one of these emails has a link at the bottom that turns them off in one click without touching your invoices or reminders. There is more on this under Emails we send you.
