Frequently asked questions
How is Premium activated?
After Stripe confirms payment, Premium access is unlocked for the same Google Account used at checkout. There's no key to copy or enter.
Why do I need to sign in first?
This ensures the purchase is tied to the correct account and reduces fraudulent payment attempts. Sign-in uses Google and reCAPTCHA.
Are local payment methods guaranteed?
No. Availability is shown by Stripe during checkout and depends on payment configuration, currency and region.
