Terms of use

Last updated: October 2026. Plain language; have it reviewed before you sell subscriptions.

What RUFFIN is. A planning calculator. It arranges the numbers you give it and projects them forward using the assumptions you set. It is not financial, tax or legal advice, and it is not a bank or a lender.

Your numbers, your decisions. Results are only as good as what you type. Check important decisions (loans, payoffs, insurance, leaving a job) with a qualified professional.

Accounts. Keep your password private. You are responsible for activity under your login.

Pro subscription. Billed by Stripe at the price shown at checkout. Cancel any time; access continues to the end of the paid period. Refunds within 14 days of a first purchase on request.

Availability. We aim to keep RUFFIN up but do not guarantee it. Export a backup regularly (Settings → Export).

Limits of liability. To the extent the law allows, RUFFIN is provided "as is" and we are not liable for financial decisions made using it.

Changes. We may update these terms; the date above changes when we do.
