Privacy Policy

Information we collect

We collect minimal information necessary to provide the service. This includes:

• Data you enter into calculators (weights, reps, exercise selection) — stored only in your browser unless you explicitly save it.
• Technical information such as browser type, device, and basic telemetry for analytics and debugging.
• Cookies and similar technologies used to preserve session state and preferences.

How we use information

We use collected information to:

• Provide and improve the calculators and user experience.
• Analyze usage patterns to fix bugs and make product decisions.
• Persist user preferences (when you opt in to saving data).

Third-party services

We may use third-party providers for analytics and hosting (for example Vercel, Google Analytics, or similar). These providers have their own privacy policies. We do not sell personal data to third parties.

Cookies

Cookies are small files placed on your device to help the site remember information about your visit. You can control cookie settings in your browser. Disabling cookies may affect functionality.

Security

We take reasonable technical and organizational measures to protect data under our control. However no method of transmission over the internet or storage is 100% secure — we cannot guarantee absolute security.

Your choices and rights

You can choose not to provide certain information, use browser settings to clear cookies, and opt out of analytics where available. If you ask us to remove saved account data (when that feature exists) we will delete it in accordance with our data retention practices.
