Do I need an account to use the calculators?
No. Every calculator works fully without signing in. An account only adds saved history, and a membership only removes ads.
What exactly does a membership change?
Advertising disappears across the whole site, pages load lighter, and your calculation history is kept longer. The calculations themselves are identical.
Can I cancel?
Yes, any time from your dashboard. Cancelling stops future renewals; you keep ad-free access until the period you already paid for ends.
Is my payment information stored here?
No. Payments are handled by the gateway. We store only the plan, the amount and the gateway's reference number — never card details.
