1
Review the plan you want
Open Pricing and choose monthly or yearly. Yearly is 20% off the monthly rate. Compare limits on Plans and limits.
2
Upgrade from Free
Choose Learner or Courses and complete Stripe Checkout. When payment succeeds, you return to Home. If checkout thinks you already have paid access, you are sent to Account → Billing instead of paying twice.
3
Manage an existing paid plan
On Billing, choose Manage Billing to open the Stripe customer portal. Use it for payment method, invoices, and portal-supported plan changes. To stop renewing, see Cancel a subscription. Access continues through the current period end.
Downgrading or cancelling does not delete your library. If a Free limit would be exceeded after a paid plan ends, new saves can be blocked until you are under the Free caps. Existing words stay. See What happens at a plan limit.
