Privacy Policy

1. Our Privacy-First Commitment

CaffeineCheck was built with a simple, ironclad premise: your health data belongs to you. We do not require accounts, we do not ask for your name or email to use the calculators, and we do not track your calculations.

2. Data Collection & Processing

When you log beverages, set your weight, age, or sensitivity profiles, all processing is performed in real time inside your browser. No data is sent to our servers.

We use standard web server logs solely for security monitoring and DDOS protection (collecting temporary network indicators like IP addresses), which are deleted automatically after 30 days. We do not link server logs to individual calculation parameters.

3. Local Storage

To allow you to save your daily logs without creating an account, CaffeineCheck uses your browser's Local Storage. This storage operates entirely on your physical machine. You can clear this data at any time by clearing your browser cache or using the reset options within the app settings.

4. Third-Party Analytics & Advertising

CaffeineCheck does not use third-party analytics trackers, behavioral advertising SDKs, or social media pixels. We do not sell, rent, or distribute user metrics to third-party data brokers or advertisement networks.

5. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted directly on this page with an updated revision date.
