Privacy Policy
Your privacy is our priority
Privacy First Approach
At SM Calculator, we believe in a simple principle: your data belongs to you. We don't collect, store, or analyze any of your personal information or calculation data.
No Data Collection
SM Calculator operates entirely client-side. This means:
- No personal information is collected
- No calculation data is sent to our servers
- No usage analytics or tracking
- No cookies for tracking purposes
Local Processing
All calculations performed on SM Calculator happen directly in your web browser. Your data never leaves your device. We use:
Local Storage
Optional history features use your browser's local storage, which only you can access.
Session Storage
Temporary data during your session, cleared when you close the browser.
Third-Party Services
We use minimal third-party services that respect privacy:
- Hosting services that don't track user activity
- CDN services for loading fonts and libraries
These services may collect anonymized technical data (like IP addresses) as part of normal web operations, but this data is not linked to your usage of our tools.
Your Control
You have complete control over your data:
Clear History
All tools with history features include clear/delete options in the interface.
Browser Controls
You can clear browser storage at any time through your browser settings.
Children's Privacy
SM Calculator is safe for users of all ages. Since we don't collect any personal information, we don't have specific data about our users' ages. Our tools are designed to be family-friendly and educational.
Policy Updates
We may update this privacy policy from time to time. Any changes will be posted on this page with an updated revision date.
