Privacy Policy.

1. Overview & Data Philosophy

At CalorieBlueprint, we prioritize user privacy above all else. We believe that your health, weight, and fitness metrics should remain entirely private. Unlike many traditional online calculators, CalorieBlueprint does not sell user data, track your identity across external websites, or force account registration to calculate your nutrition targets.

2. Information We Collect

When you use our metabolic tools (including the TDEE Calculator, BMR Calculator, BMI Calculator, and Macro Splitter), all calculations are performed locally in your web browser.

• Metabolic Inputs: Age, biological gender, height, weight, activity level, and body fat percentage entered into form fields are used solely to compute mathematical formulas.
• Browser Storage: We use browser localStorage exclusively to save your interface preferences (such as dark/light theme preference and Metric/Imperial unit selection) for convenience across sessions.
• Technical Analytics: We may collect non-identifying server log data (such as user-agent strings and IP addresses) for system security, anti-abuse monitoring, and load balancing.

3. Cookies & Local Storage

CalorieBlueprint utilizes minimal cookies and local storage tokens strictly required for site functionality. We do not use third-party advertising cookies or cross-site tracking pixels.

4. Third-Party Services

Our application is hosted on secure global cloud infrastructure. Our hosting providers may maintain standard access logs to protect against DDoS attacks and maintain system stability. No personal health information is transmitted to third-party data brokers.
