1. Information We Collect

Calculator Usage Data

We do NOT collect your calculator inputs. All token calculations, model comparisons, and cost estimates are performed entirely in your browser using JavaScript. Your input values (token counts, API call volumes) are stored only in your browser's local storage and never transmitted to our servers.

Analytics Data

We use privacy-focused analytics to understand basic usage patterns:

• Page views and visit duration
• Approximate geographic location (country/region level)
• Browser type and device category
• Referral source (how you found us)

We do NOT track individual users across sessions or create user profiles.

2. How We Use Information

The limited analytics data we collect is used solely to:

• Understand which features are most valuable to users
• Identify technical issues or performance problems
• Make informed decisions about future improvements

We never sell, rent, or share your data with third parties for marketing purposes.

3. Cookies and Local Storage

We use browser local storage to save your calculator preferences (token counts, selected models) so they persist between visits. This data never leaves your device.

We may use minimal cookies for analytics purposes. You can disable cookies in your browser settings without affecting the calculator's functionality.

4. Third-Party Services

We use the following third-party services:

• Tailwind CSS CDN - For styling (no data collection)
• Google Fonts - For typography (minimal data collection by Google)
• Analytics Provider - For basic usage statistics (anonymized data only)

These services have their own privacy policies, which we encourage you to review.

5. Data Security

Since we don't collect your calculator data, there's no sensitive information to protect on our servers. All calculations happen in your browser, and your data stays under your control.

6. Your Rights

You have the right to:

• Clear your local storage data at any time through your browser settings
• Disable analytics tracking using browser extensions or privacy tools
• Request information about any data we may have collected
• Request deletion of any data associated with your usage

7. Children's Privacy

Our service is not directed to children under 13. We do not knowingly collect personal information from children.

8. Changes to This Policy

We may update this privacy policy from time to time. We will notify users of any material changes by updating the "Last updated" date at the top of this page.
