Privacy Policy
Last updated:
Calcistry ("we", "us") operates a set of free personal-finance calculators. This policy explains what data is and isn't collected when you use the site.
The numbers you enter stay on your device
Every calculator on Calcistry runs entirely in your browser using client-side JavaScript. The figures you type — balances, income, rates, goals — are never sent to us or stored on any server. We do not have accounts, logins, or forms that transmit your financial inputs.
Information collected automatically
- Basic analytics & server logs. Like most websites, our host may record standard technical data (IP address, browser type, pages visited) to keep the site secure and understand aggregate usage.
- Cookies. We and our partners may use cookies and similar technologies for analytics and advertising, as described below.
Advertising
We may display ads served by third-party advertising partners, including Google. These partners may use cookies and device identifiers to show ads based on your prior visits to this and other websites.
- Google's use of advertising cookies enables it and its partners to serve ads based on your visits here and elsewhere. You can opt out of personalized advertising by visiting Google Ads Settings.
- You can also opt out of third-party vendor cookies at aboutads.info.
- Visitors in the EEA/UK will be asked for consent to personalized advertising and analytics cookies where required.
How we use information
Aggregate, non-identifying data is used only to operate, secure, and improve the site and to fund it through advertising. We do not sell your personal information.
Children
Calcistry is intended for a general adult audience and is not directed at children under 13. We do not knowingly collect data from children.
Your choices
You can block or delete cookies in your browser settings, use the ad-personalization opt-outs above, or use private/incognito browsing. Disabling cookies will not stop the calculators from working, since they run locally.
Changes
We may update this policy; the "last updated" date above reflects the latest version.
