Privacy Policy.
Last updated: May 2026
1. Local-First Architecture
FINCALCU is built with a local-first architecture. Your financial inputs, calculations, and records are processed directly in your browser. No personal financial data is transmitted to or stored on external servers. Your numbers never leave your device.
2. Data Ownership
You retain full ownership of all data generated within the platform. You may remove all stored data at any time by clearing your browser storage or using the reset function inside the application. Once removed, data cannot be recovered by FINCALCU or any third party.
3. Advertising — Google AdSense
FINCALCU uses Google AdSense to display advertisements that help keep this platform free for all users. Google AdSense is a third-party advertising service provided by Google LLC.
To serve relevant ads, Google AdSense may use cookies and similar tracking technologies to collect anonymized information about your visits to this and other websites. This may include your device type, browser, IP address, and pages visited. Your financial inputs are never shared with Google or any advertiser.
Google's use of advertising cookies enables it and its partners to serve ads based on your prior visits to FINCALCU or other websites. You may opt out of personalized advertising at any time by visiting Google Ad Settings.
You can also opt out of third-party vendor cookies for personalized advertising by visiting aboutads.info or networkadvertising.org. For more information on how Google uses data, visit Google's Privacy Policy.
4. Cookies
FINCALCU itself does not set cookies for tracking or user identification. However, third-party services we use — including Google AdSense and analytics providers — may set cookies on your device. These cookies are governed by the respective third parties' privacy policies. You can control or disable cookies at any time through your browser settings.
5. Analytics
We may use analytics tools such as Google Analytics to understand how visitors use FINCALCU. This data is aggregated and anonymized — it tells us which calculators are most used and how people navigate the site. It does not include your financial inputs or any personally identifiable financial data.
6. Security Model
Since all financial data remains on your device, security depends on your local environment. We recommend using updated browsers and secure devices when handling sensitive financial planning. FINCALCU does not have access to any data stored in your browser's local storage.
7. Children's Privacy
FINCALCU is not directed at children under the age of 13. We do not knowingly collect any personal information from children. If you believe a child has submitted personal information through our contact form, please contact us so we can promptly remove it.
8. Changes to This Policy
We may update this Privacy Policy from time to time. Changes will be reflected by updating the "Last updated" date at the top of this page. Continued use of FINCALCU after any changes constitutes acceptance of the updated policy. We encourage you to review this page periodically.
