Privacy Policy
Last updated: June 11, 2026
Also see our Terms of Use.
1. Overview
CalculatorsPlus ("we", "our", "us") operates calculators.plus, a free website offering online calculators for finance, health, math, date & time, construction, and unit conversion. This Privacy Policy explains how we handle information when you visit or use our site.
We are committed to minimizing data collection. Our calculators are designed so that your inputs and results are processed locally in your browser — not on our servers.
2. Your calculations stay private
When you use any calculator on CalculatorsPlus, the numbers you enter (loan amounts, health metrics, dates, measurements, etc.) are processed entirely within your web browser using client-side JavaScript. We do not transmit, store, or have access to your calculator inputs or results.
Your data never leaves your device unless you explicitly copy, share, or screenshot a result yourself. We do not require accounts, logins, or personal profiles to use our tools.
3. Information we may collect
We may collect limited, non-personal information automatically when you visit our site:
- Usage data: pages visited, time on page, referral source, and general traffic patterns
- Device data: browser type, operating system, screen resolution, and approximate geographic region (country/city level)
- Contact form data: if you use our contact page, we receive the name, email, and message you submit
We do not sell, rent, or trade your personal information to third parties for marketing purposes.
5. Third-party services
Our site may include links to external websites or embed third-party fonts and scripts (e.g., Google Fonts, analytics providers). These third parties have their own privacy policies governing how they handle data. We are not responsible for the privacy practices of external sites.
We do not integrate social login, payment processing, or advertising networks that track you across other websites.
6. Children's privacy
CalculatorsPlus is a general-audience site. We do not knowingly collect personal information from children under 13 years of age (or 16 in the EEA). If you believe a child has submitted personal information through our contact form, please contact us and we will promptly delete it.
7. Your rights
Depending on your location, you may have the following rights regarding your data:
- Access: request a copy of personal data we hold about you
- Correction: request correction of inaccurate data
- Deletion: request deletion of personal data we hold
- Objection: object to processing based on legitimate interests
- Portability: receive your data in a structured, machine-readable format (GDPR)
Because calculator inputs are not stored on our servers, most requests will relate to contact form submissions or analytics data. To exercise your rights, contact us via the contact page.
8. Data retention
Contact form messages are retained only as long as needed to respond and resolve your inquiry, then deleted unless we are required to keep them for legal purposes. Analytics data is retained according to our analytics provider's default retention settings (typically 14–26 months).
9. Changes to this policy
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last updated" date. Continued use of the site after changes constitutes acceptance of the revised policy.
