Privacy Policy

What we collect

Cost Ripple does not require an account and does not transmit the expense names or amounts you enter. All calculations run locally in your browser.

Local storage

We store a single preference — your light or dark theme choice — in your browser's local storage. Clearing site data removes it.

Shared links

If you create a share link, the calculator settings you chose are encoded in the URL. Anyone with that link can see those settings, so only share it when you are comfortable doing so.

Analytics

Cost Ripple uses privacy-conscious, aggregate analytics such as page views and anonymous feature usage. Analytics events never include your expense name or amounts.

Advertising

This site displays advertising served by Google AdSense. Google and its advertising partners use cookies (such as the DoubleClick cookie) to serve ads based on your prior visits to this site and other websites, and to measure ad performance. Third-party vendors and ad networks may also serve ads on this site.

You can opt out of personalised advertising at Google Ads Settings, and opt out of third-party vendor cookies at aboutads.info/choices. Learn how Google uses information from sites that use its services at Google’s partner-sites policy.

Cookies

Cost Ripple itself only stores your theme preference. Advertising cookies are set by Google and its partners as described above — see the cookie policy for the full list and controls.

Changes

If this policy changes materially, the updated version will be published on this page.
