Privacy Policy

Last updated: May 2026

1. What Data We Collect

MolesToGrams Calculator does not collect any personally identifiable information (PII). We do not require registration, accounts, or email addresses to use any calculator on this site.

2. Local Storage

Some calculators store your recent calculation history in your browser's localStorage. This data is stored only on your device and is never transmitted to our servers. You can clear it at any time by clearing your browser's site data.

3. Theme Preference

Your dark/light theme preference is saved in localStorage under the key mmc_theme. This data never leaves your device.

4. Cookies

We do not currently use cookies for tracking or analytics. If we add analytics in the future, this policy will be updated and a consent mechanism will be added.

5. Third-Party Services

Social sharing buttons (Facebook, Twitter, LinkedIn, WhatsApp, Email) are implemented using standard share URLs and do not load third-party scripts. Clicking a share button opens the respective platform in a new tab; their privacy policies apply from that point.

6. Children's Privacy

This site is intended for general educational use. We do not knowingly collect data from children under 13. As no personal data is collected at all, there is no risk of inadvertent collection.

7. Your Rights (GDPR / CCPA)

Because we collect no personal data, there is nothing to access, correct, or delete on our end. You can delete any localStorage data held on your own device through your browser settings.

8. Changes to This Policy

We may update this Privacy Policy to reflect changes in our practices. The "Last updated" date at the top of this page will reflect any changes.
