At breathometer.me, we take your privacy seriously. This privacy policy explains how we handle your information when you use our BAC calculator tool.
Local Storage Only: All your personal data (weight, gender, drinking session details) is stored locally in your browser using localStorage. We do not transmit this information to our servers or any third parties.
IP-Based Location: On your first visit, we may use your IP address to detect your country for setting default BAC legal limits. This is not stored or logged.
No Tracking: We do not use cookies, analytics, or any tracking mechanisms to monitor your behavior.
The information you enter (weight, drinks, timing, etc.) is used solely to calculate your estimated BAC. All calculations happen in your browser, and no data leaves your device.
Since all data is stored locally on your device, you have complete control over it. You can clear your data at any time by clearing your browser's localStorage or cache.
We do not share your data with any third-party services. This website does not integrate with external analytics, advertising, or tracking platforms.
You have the right to access, modify, or delete your data at any time by using your browser's developer tools or clearing your browser data.
We may update this privacy policy from time to time. Any changes will be posted on this page with an updated revision date.
If you have any questions about this privacy policy, please contact us through the information provided on our website.
