FAQ
Questions, answered
How does billing work?
Pick monthly or annual — it renews automatically at the end of each period and you can cancel anytime from Settings. Prefer no subscription? Choose the one-time 1-Year or Lifetime plan instead.
Is there a refund policy?
Yes. Every plan is covered by a 7-day money-back guarantee — if it is not for you, request a refund within 7 days.
What is regional pricing?
We offer purchasing-power-parity pricing for many regions. If your country qualifies, flip the “Regional pricing” toggle to apply the discount. The price you see is exactly what you are charged at checkout.
Can I pay once instead of subscribing?
Absolutely — open “Prefer to pay once?” to choose 1-Year access (12 months, no auto-renewal) or Lifetime (pay once, yours forever, including future questions).
How do I cancel?
Cancel in one click from Settings, or via the Dodo customer portal. You keep full access until the end of your paid period.
