What stays free?
Every formula and glossary page, the descriptive-statistics calculators, the first learn module, the Sampling & CLT simulation, and a 20-question practice starter set are free forever - no account needed.
How is my access stored?
Purchases are handled by RevenueCat and Stripe. An anonymous purchase id is kept in this browser so StatRise recognises your Premium access on this device. Keep your receipt email for recovery.
Can I use Premium on another device?
Yes. Every subscriber gets an access code (shown above once you're Premium, and in your receipt email). Enter it on the restore page to unlock StatRise on any other browser or device.
Lost your access code?
Reply to your Premium receipt email from the address on file - it's linked to your subscription, so we can look up your access code and get you back in.
Can I cancel?
Yes. Subscriptions renew automatically and can be cancelled anytime from the link in your receipt email. Lifetime is a one-time payment.
