Billing, cancellation and refunds
- Paid plans are monthly subscriptions in US dollars, paid by card through Stripe. New subscribers get a 3-day free trial.
- Cancel at any time in the app or by email; the plan stays active to the end of the paid month and is not charged again.
- Duplicate charges, charges after cancelling, and months the service was unavailable through our fault for more than 3 days in a row are refunded in full. Otherwise a month is not refunded part-way through.
- Questions about a charge: support@proven-decisions.ai.
During the beta the app is free for invited testers; paid plans open after the beta, and prices may change before then.
