Privacy Policy
Last updated 2026-10-24.
Keys & Cents (“we”) respects your privacy. This policy explains what we collect and why.
Calculators
Our calculators run entirely in your browser. The numbers you enter are not sent to us or stored on our servers. On some pages your inputs appear in the page address (URL) so you can bookmark or share a scenario; that stays on your device unless you share it.
Newsletter
If you subscribe, we collect your email address to send the newsletter. Our email service provider processes it on our behalf. Every email has an unsubscribe link, and you can ask us to delete your address at any time.
Purchases
Payments are processed by Stripe. We receive your name, email and purchase details to deliver your product and provide support. We never see or store your full card number. See Stripe’s privacy policy.
Analytics & cookies
We may use privacy-friendly, cookieless analytics to count page views and improve the site. We do not use advertising cookies or sell personal information. If we add any cookie-based tools, we will update this page first.
Affiliate links
When you click an affiliate link, the partner may use cookies to credit us for a referral. Their privacy policies apply on their sites.
Your rights
Depending on where you live (for example California or the EU/UK), you may have rights to access, correct or delete your personal information. Email hello@keysandcents.com and we’ll help.
Children
Our site is not directed to children under 13, and we do not knowingly collect their information.
