Privacy Policy

This privacy policy explains how Dope Calculator ("we", "us", or "our") manages user information. Because we build our tools using client-side calculation models, our data practices are designed to protect your privacy fully.

1. No Input Data Retention

When you use any calculator on our website (such as mortgage, interest, BMI, or percentage calculators), all math calculations are performed locally in your web browser. We do not transmit your numeric inputs, parameters, or calculated outputs to our servers, nor do we store them in any database.

2. Anonymous Usage Counting

We maintain anonymous, aggregate counters of how many times each calculator page is visited. This helps us surface the most popular tools on our homepage. These counters contain no personal data, no identifiers, and are not linked to any individual user or session.

3. Cookies and Local Storage

Dope Calculator does not set advertising tracking cookies, nor do we build user profiles. We may use essential local browser storage only if necessary to save your preferences (e.g. toggles between metric and imperial units) for your future visits.

4. Log Files

Like most website servers, we collect basic web server log files (such as IP address, browser type, referral URL, and timestamp) solely for website maintenance, security monitoring, and server performance debugging. This data is not linked to individual calculation inputs.

5. Third-Party Links

Our website may contain links to external sites. We are not responsible for the privacy practices of those sites. We encourage you to review the privacy policies of any external websites you visit.
