Clamly offers three plans so you can choose the level of access that suits your study goals. Payments are processed securely through Stripe — Clamly never sees or stores your card details. You can upgrade, downgrade, or cancel at any time from the Billing page.

​

Cancelling your subscription does not delete your account or any of your study data. Everything you’ve created in Clamly stays intact on the Free plan.

​
Payment Security

Clamly uses Stripe to handle all payment processing. Stripe is a PCI-DSS Level 1 certified payment provider — the highest level of certification available.
No. Your card number, CVV, and other payment credentials are entered directly into Stripe’s secure, encrypted checkout page. Clamly never sees, receives, or stores your card details at any point.
Clamly stores only your Stripe customer ID and subscription status — the information needed to know which plan you’re on. No card data of any kind is held on Clamly’s servers.
Refunds are handled in accordance with applicable consumer protection law. If you believe you are entitled to a refund, contact support@clamly.app with your request and order details.
