Plans, billing and cancellation

The free plan covers the core study tools with daily usage limits. Paid plans raise those limits and unlock the heavier tools. Current inclusions and prices are on the pricing page.

Payment

Payments are handled by our payment providers; we never see or store your full card details. Available methods depend on your region and are shown at checkout.

After paying

Plan activation is normally immediate. If your plan has not changed within a few minutes, reload the page — the entitlement is confirmed by the provider's webhook, which can lag briefly. If it is still wrong after fifteen minutes, contact support with the date and amount and we will reconcile it.

Invoices

Receipts are emailed at the time of payment and your billing history is available in account settings.

Changing or cancelling

• Upgrades take effect immediately.
• Cancellation stops future renewals; paid features remain available until the end of the current billing period.
• Refunds are governed by our refund policy — check it before requesting one.
