Privacy Policy

BlinkCalc is designed with privacy at its core. We do not collect, store, or transmit any personal data you enter into our tools.

All calculations, conversions, and tool outputs happen entirely within your browser. The data you type, whether it is a number, a piece of text, or an uploaded file, never leaves your device.

We do not require you to create an account, provide an email address, or share any personal information to use BlinkCalc.

We use only the minimum information needed to run BlinkCalc reliably and improve it over time.

Aggregated, non-identifying usage information helps us understand which tools are popular, where pages can load faster, and where explanations can be clearer.

We do not sell personal information, and we do not build advertising profiles from your tool inputs.

BlinkCalc uses a small number of essential cookies to make the site work correctly. These include cookies that remember your theme preference (light or dark mode).

Optional analytics and advertising cookies are off by default until you save your choices on the Cookie Settings page in browsers where this preference system is available.

Where legally required, including for visitors in the UK, EEA, and Switzerland, optional analytics and advertising cookies are used only after consent is given.

We do not sell cookie data to third parties. You can manage or disable cookies in your browser settings at any time, or visit the Cookie Settings page linked below to update BlinkCalc preferences.

BlinkCalc may use analytics tools, such as Google Analytics, after analytics cookies are enabled to understand how visitors use the website, identify popular tools, monitor performance, and improve content.

Analytics data is generally aggregated and does not require users to create an account. It may include information such as page URLs visited, approximate location at country or region level, device type, browser, and referring source.

We use analytics only to improve the website and the usefulness of its calculators and articles.

When advertising cookies are enabled, third-party vendors, including Google, may use cookies to serve ads based on a user's prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to BlinkCalc visitors based on their visits to BlinkCalc or other sites on the Internet.

Third-party vendors may place and read cookies, use web beacons, or use IP addresses as part of ad serving, fraud prevention, frequency capping, reporting, and measurement.

Users can opt out of personalised advertising by visiting Google's Ads Settings, and can opt out of a third-party vendor's use of cookies for personalised advertising by visiting www.aboutads.info.

Where available, advertising-related cookies can also be reviewed via our Cookie Settings page.

BlinkCalc does not require accounts and does not intentionally store calculator inputs as personal profiles.

Technical logs (such as server access logs), analytics data, and support messages you send us may be retained for a limited period as needed for security, troubleshooting, legal compliance, and site improvement.

We aim to keep retention periods proportionate, no longer than is necessary for the purpose for which the data was collected.

Because BlinkCalc does not collect or store personal data from tool inputs, there is no database of user information to protect.

The site is served over HTTPS, which encrypts the connection between your browser and our servers.

We take reasonable technical measures to keep the platform secure and to address any vulnerabilities we become aware of.

You can clear or block cookies through your browser settings at any time.

You can opt out of personalised advertising via Google's Ads Settings or aboutads.info.

You can adjust optional cookie categories on the Cookie Settings page.

BlinkCalc is intended for general audiences and does not knowingly collect personal data from children under 13. If you believe a child has submitted personal information through our site, please contact us and we will remove it promptly.

We may update this Privacy Policy from time to time. When we do, we will update the 'Last updated' date at the top of this page.

We encourage you to review this policy periodically. Continued use of BlinkCalc after any changes indicates your acceptance of the updated policy.
