Quick navigation
1. Information we collect
The information collected depends on how you use the site.
Information you provide
- Contact details you submit, such as name, email address, subject, and message.
- Feedback, calculator requests, support questions, and any files or examples you choose to share.
- Saved calculation data if you choose to use save features. The current saved-calculation feature stores this data in your browser local storage.
Information collected automatically
- Device and browser details, such as browser type, operating system, screen size, and approximate region.
- Usage data, such as pages visited, referring pages, search terms, feature interactions, and error events.
- Cookie identifiers or similar technologies used for analytics, security, preferences, or advertising where enabled.
2. How we use information
- Operate, maintain, secure, and improve the website and calculators.
- Respond to support messages, calculator requests, and policy questions.
- Understand which calculators and pages are useful so we can prioritize improvements.
- Detect abuse, troubleshoot technical issues, and protect site availability.
- Show ads or measure ad performance if advertising services are enabled.
- Comply with legal obligations and enforce our terms when necessary.
5. Security and retention
We use reasonable technical and organizational measures to protect information. No website, browser storage system, or internet transmission is completely secure, so sensitive decisions should not depend on this site as a secure vault.
We keep information only as long as needed for the purposes described in this policy, unless a longer period is required for legal, security, or operational reasons. Browser-stored saved calculations remain on your device until you delete them, clear site data, or use the site controls that remove them.
6. Your choices
- You can avoid submitting contact information by not using the contact form or email links.
- You can clear saved calculations through site controls or by clearing browser storage for this site.
- You can block or delete cookies through your browser settings.
- You can request access, correction, or deletion of personal information you have submitted, subject to legal and operational limits.
- You can opt out of some advertising personalization through browser, device, and advertising network controls.
7. Children privacy
Do The Calculation is not directed to children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided personal information, contact us so we can review and remove it where appropriate.
8. International visitors
The website may be accessed from different countries, and service providers may process information in countries other than your own. Where required, we use appropriate safeguards for such processing.
9. Changes to this policy
We may update this Privacy Policy as the website, legal requirements, or service providers change. The updated date on this page will reflect the latest revision.
