In plain words
The free account is not a trial and does not run out; it is the first two nodes of every course, for as long as you want them. Accounts opened before September 13, 2026 at 00:30 UTC have all Family features until October 13, 2026 at 00:00 UTC; then Free limits apply unless you subscribe, and existing saved results are retained. The price you join at stays yours for as long as you keep the plan.
The plan renews on its own, monthly or yearly, and you can stop it any time from the account page; it runs to the end of the period already paid for. A yearly plan cancelled within the first fourteen days is refunded in full. Cards are handled by our payment provider; this site never sees the number.
