You can cancel at any time from the Account page inside the app, which opens the Stripe customer portal. Cancellation takes effect at the end of the period you have already paid for — you keep Pro until then, and you are not charged again.
If it is not what you expected, email us within 14 days of a monthly payment and we will refund it in full, no questions asked.
For the pay-as-you-go plan, we bill for time actually spent working in the app, measured on our server. If you believe you have been billed for time you did not use, tell us and we will look at the record and refund anything that is wrong.
Refunds are returned to the card that was charged, and usually appear within 5–10 business days depending on your bank.
If a payment fails, Stripe retries it over the following days. Your access continues during that time. If every retry fails, the subscription is cancelled and the account returns to the free plan. Nothing is lost — your saved setups stay where they are.
