Privacy Policy

Effective date: March 13, 2026

sum.money is a free financial calculator platform. We believe your financial data is none of our business. This policy explains what we collect (almost nothing) and what we don't.

No cookies

sum.money does not set any cookies — no session cookies, no tracking cookies, no analytics cookies. Your browser's cookie jar stays empty.

No analytics or tracking

We do not use Google Analytics, Facebook Pixel, or any other third-party tracking service. We do not fingerprint your browser. We do not build user profiles. There is no retargeting.

No personal data collection

We do not collect your name, email address, IP address, or any other personal information. There are no accounts, no sign-ups, no newsletters, and no contact forms.

All calculations run in your browser

Every calculator on sum.money runs entirely in your browser using JavaScript. The numbers you enter never leave your device — they are not sent to any server. When you close the tab, the data is gone.

Shareable URLs

When you click "Share", your calculator inputs are encoded into the URL as query parameters (e.g., ?amount=10000&rate=5). This URL stays in your browser's address bar. We do not log, store, or process shared URLs on our servers. Anyone you share the link with can see the values in the URL.

Hosting

sum.money is hosted on Cloudflare Pages. Cloudflare may collect standard web server logs (IP address, user agent, request URL) as part of their infrastructure. We do not access or process these logs. See Cloudflare's Privacy Policy for details.

Third-party content

sum.money does not embed third-party scripts, ads, or social media widgets. No external requests are made from your browser when you use our calculators.

Children's privacy

sum.money does not knowingly collect any data from anyone, including children under 13. Since we collect no personal data at all, there is nothing to protect or delete.

Changes to this policy

If we change this policy, we will update the effective date at the top of this page. Since we don't have your email, we can't notify you — but there's not much to change when you collect nothing.
