Common questions

Is it really free to use?

Yes. Every calculator and generator works on screen without an account or a card. You pay only if you want to keep the result: download a PDF, CSV or Word file, save your work, or share it.

What does the one-time unlock include?

$15 unlocks the paid features of one tool for good. There is no renewal.

What is All-Access?

$29 a month unlocks every tool, including new ones as they are added. Cancel any time from your dashboard and keep access until the end of the period you paid for.

Do the tools use AI?

No. Every result comes from fixed formulas and rules, so the same inputs always give the same answer, and nothing you enter is sent to an AI service.

What happens to my data?

Calculations run in your browser. Your work is stored only if you choose to save it to your account, and you can delete it whenever you like. We do not sell data.

Can I get a refund?

Yes. If a one-time unlock or an All-Access monthly charge is not what you needed, ask within 14 days and it is refunded.
