Questions
Before you buy
Can I try it before paying?
Yes. The Free plan has no time limit and needs no card. Upgrade from inside the app whenever you need more.
What if Premium isn't right for me?
Every paid plan has a 14-day money-back guarantee: email us within 14 days and we refund the full amount. After that, we refund the unused part of your period.
Can I switch plans later?
Anytime, from Plans & billing in the app. Unused time on your current plan is credited: upgrading costs only the difference, and a downgrade refunds it to your PayPal.
What happens if I cancel?
Renewal stops right away, and you keep your paid features until the end of the period you paid for. After that your account moves to Free and your saved data stays in it.
How do I pay?
Through PayPal's secure checkout, with a PayPal account or a debit or credit card. Prices are in US dollars, and we never see your card details.
Do unused AI questions roll over?
No. Your AI advisor allowance resets at the start of each month.
