Pricing FAQs
- Are the calculators free?
- Yes. Every calculator is free to run, with no sign-up wall. Sign-in is optional and only matters if you want to save scenarios across devices.
- What happens to a Free scenario after 7 days?
- It’s locked, not deleted. You see it in your list with a lock icon. Open it to upgrade to Plus and the scenario unlocks instantly — your data is preserved throughout.
- Why annual, not monthly?
- $30/year ($2.50/month) keeps the price honest and the billing predictable. We’d rather price the suite at a fair annual fee than nickel-and-dime with subscriptions you forget to cancel.
- Can I cancel?
- Yes. Cancel any time — your subscription stays active through the end of the period you paid for, then drops back to Free (with a 7-day rolling window for re-edits).
