Privacy Policy
Last updated: March 2025
1. Overview
Proteinary (“we”, “us”, or “our”) is a free, browser-based nutrition calculator. This Privacy Policy explains how we handle information when you use our website.
2. Information We Collect
Proteinary operates entirely in your browser. All calculations — including your body weight, age, and fitness goal — are processed locally on your device and are never transmitted to or stored on our servers.
We do not require you to create an account, provide an email address, or submit any personally identifiable information to use the service.
3. Cookies & Local Storage
We do not use tracking cookies or advertising cookies. We may use browser local storage solely to improve your experience (for example, remembering your last selected unit preference). No personal data is stored via these mechanisms.
4. Analytics
We may use privacy-respecting, anonymised analytics tools to understand aggregate usage patterns (such as page views and general geographic region). These tools do not track individual users or build personal profiles, and no personally identifiable information is collected.
5. Third-Party Services
Our website is hosted on third-party infrastructure (such as cloud hosting providers). These providers may process your IP address as part of standard web server operations. We do not share, sell, or otherwise disclose your data to any third parties for marketing or advertising purposes.
6. Children's Privacy
Proteinary is not directed at children under the age of 13. We do not knowingly collect any information from children. If you believe a child has provided information through our service, please contact us so we can address it promptly.
7. Changes to This Policy
We may update this Privacy Policy from time to time. Any changes will be reflected on this page with a revised “Last updated” date. Continued use of Proteinary after changes are posted constitutes your acceptance of the updated policy.
