1. Who we are
ChemistryCalculators.net (“we”, “us”, “our”) provides free and premium chemistry calculation tools for educational and professional use. You can reach us through the contact page.
2. Data we collect
Important: We do NOT store, collect, or retain any calculation inputs, formulas, or results that you enter into our calculators. All calculations are performed locally in your browser, and we have no access to your input data.
- Usage analytics: Anonymous metrics (page views, device type, browser type) may be collected through third-party analytics services to help us prioritize improvements. We never collect formula inputs or calculation results.
- Error logs: When a calculator fails, we may capture the browser type and timestamp to troubleshoot technical issues. No calculation data is included in these logs.
- Voluntary submissions: Emails you send to us, or form data you submit through contact forms, include the personal details you choose to provide.
3. Cookies & local storage
We use essential cookies and local storage to remember interface preferences (dark mode, unit selections) and to ensure calculators perform as expected. These preferences are stored locally on your device and are not transmitted to our servers.
Third-party services: We use Google Analytics and Google Ads. These services use cookies and similar technologies to collect information about your use of our website. Google Analytics collects information such as how often users visit our site, what pages they visit, and what other sites they used prior to coming to our site. Google Ads uses cookies to serve ads based on your prior visits to our website or other websites.
You can opt out of Google Analytics by installing the Google Analytics Opt-out Browser Add-on. You can also manage your ad preferences through Google's Ad Settings.
4. How we use your information
- Operate, maintain, and secure the calculators.
- Respond to support requests, feature suggestions, or partnership inquiries.
- Comply with legal obligations and enforce our Terms of Service.
5. Data retention
We do NOT store personal data. As stated throughout this policy, we do not maintain databases, servers, or storage systems that retain your personal information, calculation inputs, or results.
Any emails or contact form submissions you send to us may remain in our email inbox for reference purposes, but we do not systematically store, archive, or retain this information in any organized database. We do not collect or store aggregated analytics ourselves—any analytics data would be collected and stored by third-party services (such as Google Analytics) according to their own retention policies, which we do not control.
6. Your rights
Important: As stated in Section 2, we do NOT store, collect, or retain any calculation inputs, formulas, or results. We do not maintain databases of user personal information.
If you are in a jurisdiction that provides privacy rights (such as GDPR or CCPA), please note:
- Voluntary submissions: If you have contacted us via email or contact forms, you may request access, correction, or deletion of that correspondence through the contact page. We verify identity before granting access.
- Third-party data: Any data collected through third-party services (such as Google Analytics or Google Ads) is managed by those third parties according to their own privacy policies. We do not have access to or control over this data. To exercise your rights regarding third-party data, you must contact those services directly:
- For Google Analytics: Use the Google Analytics Opt-out Browser Add-on or contact Google directly
- For Google Ads: Manage your preferences through Google's Ad Settings
Since we do not store personal data ourselves, there is typically no personal data in our possession that can be accessed, corrected, or deleted beyond any voluntary communications you may have sent to us.
7. Third-party services
We rely on secure infrastructure providers (hosting, CDN) and use third-party analytics and advertising services, including but not limited to Google Analytics and Google Ads. These third-party services have their own privacy policies governing the collection and use of your information.
Google Analytics: We use Google Analytics. It collects information about your use of our website. Google's ability to use and share information collected by Google Analytics about your visits to our site is restricted by the Google Analytics Terms of Service and the Google Privacy Policy.
Google Ads: We use Google Ads. Google uses cookies to serve ads based on your prior visits to our website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to our site and/or other sites on the Internet. You may opt out of personalized advertising by visiting Google's Ads Settings.
We do not have control over these third-party services' data collection practices. We encourage you to review their privacy policies to understand how they handle your information.
8. Updates to this policy
We may modify, update, or change this Privacy Policy at any time without prior notice. It is your responsibility to review this Privacy Policy periodically. The "Last updated" date indicates the latest revision. Your continued use of the Service after any changes to this Privacy Policy constitutes your acceptance of those changes. If you do not agree to any changes, you must discontinue use of the Service immediately.
9. No responsibility disclaimer
ChemistryCalculators.net assumes NO responsibility or liability whatsoever for:
- Any errors, inaccuracies, or omissions in calculator results or outputs
