💳 Billing & cancellation

  • All payments are final and non-refundable — subscriptions and the one-time Lifetime purchase alike.
  • Cancel anytime. Cancelling simply stops the next renewal — there's no penalty and no questions asked.
  • You keep what you paid for. After you cancel, Premium stays active until the end of the period you've already paid for. Cancel a monthly plan and Premium runs to the end of that month; an annual plan, to the end of that year. It does not renew after that.
  • Lifetime is a single one-time purchase — yours forever, and likewise non-refundable.
  • Payments and subscription management are handled securely by our payment provider. Full details are in our Terms of Service.
