We collect minimal data, never store your calculations, and never sell your information.

Last updated: 2025

1. Introduction

We are committed to protecting your privacy. This policy explains how we collect, use, and protect information when you visit casiocalculator.online. Our core principle is simple: your calculations are private. We do not store, track, or analyse your mathematical operations.

2. Information We Do Not Collect

We want to be clear about what we never collect:

  • Your calculation inputs, results, or operations
  • Personal identification information
  • Financial data
  • Location data
  • Device identifiers

3. Information We May Collect

We may collect limited non-personal data to improve the service, including:

  • Page views
  • Browser type
  • Device type (mobile or desktop)
  • General geographic region (country level only)
  • Referral source

This data is anonymised and is never linked to individual users.

4. How We Use Information

The limited data we collect is used solely for:

  • Service improvement — improving performance, compatibility, and fixing bugs
  • Website analytics — understanding traffic patterns and popular features

We never use data for advertising, marketing, or selling to third parties.

5. Cookies

We use minimal cookies:

  • Essential cookies — session only, required for basic functionality
  • Analytics cookies — 30-day lifespan, anonymised, optional
  • Preference cookies — 1 year, used to remember your settings

You can control or disable cookies through your browser settings at any time.

6. Data Security

We take reasonable steps to protect your information:

  • HTTPS encryption on all pages
  • Industry-standard server security practices
  • Limited access to any collected data
  • Regular security updates

7. Your Rights

You have the right to access, correct, delete, and port any data we hold about you. Because we collect very little, exercising these rights is straightforward. To make a request, contact [email protected].

8. Children's Privacy

Our service is suitable for all ages. We do not knowingly collect personal information from children under 13. Because we don't store calculations, there are minimal privacy concerns for student use.

9. Third-Party Services

We may use anonymised analytics services such as Google Analytics. These services cannot identify individual users. External links on our site are not covered by this privacy policy.

10. Changes to This Policy

We may update this policy from time to time and will post any changes on this page with an updated date. Significant changes will be highlighted prominently so you are always informed.
