Privacy Policy

1. Information We Collect

BitKitTools does not directly collect personal information through our servers. However, the following types of information may be processed through your browser or third-party services to improve service quality and serve advertising.

• Cookies: Services such as Google AdSense (advertising), Google Analytics 4 (visit statistics), and Microsoft Clarity (user behavior analysis) use cookies. You can manage cookie consent through the consent banner displayed on our site.
• LocalStorage: We store recently used tools, favorites, and last-entered values in your browser's LocalStorage. This data remains on your device only and is never transmitted to our servers.

2. Sensitive Tool Input Data

Data you enter into sensitive tools — such as the BAC Calculator, Baby Growth Percentile Calculator, and Baby Sleep Schedule Calculator — including body weight, health information, and similar inputs, is processed entirely within your browser. This data is never transmitted to our servers or any third-party servers.

Input values in the BAC Calculator (sex, weight, alcohol intake) are not saved to LocalStorage due to their personally identifiable nature.

• Google AdSense: Personalized advertising — Google LLC
• Google Analytics 4 (GA4): Visitor statistics and analytics — Google LLC

4. Withdrawing Consent

You may change or withdraw your cookie consent at any time through the cookie consent banner displayed at the bottom of the page or in a corner of your screen. Withdrawing consent will stop the use of personalized advertising and analytics cookies.

You may also delete or block cookies directly through your browser settings. Note that blocking cookies may prevent some features from working correctly.
