Privacy Policy

Your privacy matters. This policy explains what we collect and how we use it—in plain language.

Last updated: February 2026

In short: Our platform runs entirely in your browser. We do not collect or store any of your calculation inputs or results. If you create an account or sign in with Google, we only keep your email for our records—we do not use it for marketing or mailing.

1. Who We Are

Shawon Calculators (“we”, “our”) provides free online calculators. Our services are designed to run on your device (client-side). Your data stays with you.

2. Information We Do Not Collect

Because our tools work in your browser:

  • We do not collect, store, or see the numbers or data you enter into any calculator.
  • We do not store your calculation history or results.
  • We do not use your usage data for advertising or profiling.

3. Information We Collect (Account Only)

We only collect information when you choose to create an account or sign in with Google:

  • Email address — For account identification and recovery only. We do not use it for newsletters, marketing, or any mailing.
  • Name (optional) — If you provide it or it comes from Google, we use it only to personalize your experience (e.g. “Hi, [Name]”).

This information is kept for our records and to manage your account. It is not sold or shared with third parties for advertising.

4. Cookies & Local Storage

We use a minimal set of cookies and similar tech:

  • Session / login cookies — So you stay signed in.
  • Security (e.g. CSRF) — To protect your account.

We do not use cookies for advertising or cross-site tracking. For more detail, see our Cookie Policy.

5. Third-Party Services

We may use:

  • Google Sign-In — So you can log in with your Google account. Google’s privacy policy applies to that sign-in.
  • Google AdSense — To show ads. AdSense may use cookies and data per Google’s policy; we do not control that. You can manage ad preferences via Google’s settings.
  • Google Fonts — For typography; may involve requests to Google’s servers.

6. Data Security

We use HTTPS and follow good practices to protect account data. Because calculations run in your browser, your calculation data is never sent to our servers.

7. Your Rights

You can:

  • Use most tools without an account (no data collected).
  • Request access to or deletion of your account data by contacting us.
  • Use browser settings to manage or block cookies.

8. Children

Our service is not directed at children under 13. We do not knowingly collect personal data from children.

9. Changes to This Policy

We may update this Privacy Policy from time to time. The “Last updated” date at the top will change. We encourage you to review this page occasionally.
