How We Use Information

Data Storage and Security
Local Processing
All calculations are performed locally in your web browser. Your input data never leaves your device and is not transmitted to our servers. When you enter values into our calculators, they are processed entirely on your device using JavaScript.
No Data Storage
We do not store any of your calculation inputs, results, or personal data on our servers. Each time you use a calculator, it's a fresh session with no memory of previous calculations.
Security Measures
- HTTPS encryption for all connections
- Regular security audits and updates
- Secure hosting infrastructure
- No third-party tracking scripts
Cookies and Tracking
What We Don't Use
- No tracking cookies
- No analytics cookies
- No advertising cookies
- No social media tracking pixels
- No third-party tracking services
Essential Functionality
We may use minimal local storage (localStorage) to remember your preferences like dark mode settings. This data stays on your device and is never transmitted to our servers.
Third-Party Services
We minimize the use of third-party services to protect your privacy. Currently, we may use:
Content Delivery Network (CDN)
We use a CDN to deliver our website faster globally. The CDN provider may log basic technical information like IP addresses for security purposes, but this data is not shared with us.
Hosting Provider
Our website is hosted on secure servers that may maintain basic server logs for security and performance monitoring. These logs are automatically deleted after 30 days.
Your Rights and Choices
Since we don't collect personal data, most traditional privacy rights don't apply. However, you have:
Complete Control
All your data stays on your device. You can clear your browser data anytime to remove any locally stored preferences.
No Account Required
Use all our services without creating an account or providing any personal information.
Transparency
This privacy policy clearly explains our practices. If you have questions, contact us anytime.
Open Source
Our calculator code is transparent and can be audited to verify our privacy claims.
Children's Privacy
Our service is safe for users of all ages, including children under 13. Since we don't collect any personal information, there are no special privacy concerns for younger users. Parents can feel confident letting their children use our educational calculators.
We comply with the Children's Online Privacy Protection Act (COPPA) by not collecting any personal information from users of any age.
International Users
Our service is available globally. Since we don't collect personal data, most international privacy regulations don't apply. However, we respect the privacy principles of:
- European Union General Data Protection Regulation (GDPR)
- California Consumer Privacy Act (CCPA)
- Canadian Personal Information Protection and Electronic Documents Act (PIPEDA)
- Other applicable privacy laws worldwide
Our privacy-first approach means we exceed the requirements of most privacy regulations by simply not collecting personal data in the first place.
