Which payment methods can I use?

Card payments (via Stripe) are a subscription: billed monthly and renewed automatically until you cancel.

PayPal and cryptocurrency buy a single access period (30 days for a monthly plan, 365 days for a yearly plan) and do not renew by themselves. To continue, pay again before the period ends.

Crypto transfers cannot be reversed on the blockchain, so check the currency, address and amount carefully. In the mobile apps, purchases go through the app store only.
