• Messages: Any feedback or questions you send us

6. Cookies and Browser Storage

We use browser storage to keep you signed in and preserve essential account preferences. On the production website, Google Analytics loads after you interact with the site and may use analytics cookies to help us understand page and feature usage. You can control cookies and stored website data through your browser settings.

7. Data Security

We implement appropriate security measures to protect your information. However, no internet transmission is 100% secure, and we cannot guarantee absolute security. You provide your information and use the Service at your own discretion and risk, and to the maximum extent permitted by law we are not liable for unauthorized access to, or alteration or loss of, your data resulting from events beyond our reasonable control.

8. Children's Privacy

ChemWhiz accounts are intended for users aged 13 and older, and creating an account requires confirming that you are at least 13. We do not knowingly collect personal information from children under 13. If you believe a child under 13 has provided us personal information, contact us and we will delete it. If you are under the age of majority where you live, you may use ChemWhiz only with the involvement and consent of a parent or legal guardian. Browsing the free content does not require an account and does not involve providing personal information to us.

9. Your Rights

Depending on your location, you may have the right to:

• Access the personal information we hold about you
• Request correction of inaccurate information
• Request deletion of your information
• Opt out of marketing communications

To exercise these rights, contact us at the email below.
