How Your Data Works

When you use PoolMath Pro calculators:

1. You enter your data (pool dimensions, test results, etc.) into the calculator form
2. JavaScript calculates results in your browser - nothing is sent to our servers
3. Results are saved locally using IndexedDB (browser storage) so you can access them later
4. You control your data - clear your browser storage to delete all saved information

What We Do Collect

We use analytics to understand how visitors use PoolMath Pro:

• Page Views: Which calculators are most popular
• Browser Type: To ensure compatibility (Chrome, Safari, Firefox, etc.)
• Device Type: To optimize for mobile, tablet, and desktop
• Referral Source: How you found PoolMath Pro (search, link, direct)

This analytics data is anonymous and aggregated. We cannot identify individual users.

Cookies

PoolMath Pro may use minimal cookies for:

• Preferences: Remembering unit system (imperial/metric)
• Analytics: Anonymous usage tracking (see above)

You can disable cookies in your browser settings, but some features may not work properly.

Third-Party Services

PoolMath Pro may use:

• Analytics Services: To track anonymous usage statistics
• Hosting Providers: To serve the website (Vercel, Cloudflare, etc.)

These services have their own privacy policies. We choose providers with strong privacy practices.

Your Rights

Since we don't collect personal data, there's nothing to request, delete, or export. Your pool data lives in your browser only:

• To delete your data: Clear your browser's local storage and cookies
• To export your data: Use your browser's developer tools to access IndexedDB
• To stop analytics: Use browser extensions like uBlock Origin or Privacy Badger

Children's Privacy

PoolMath Pro does not knowingly collect information from children under 13. Since we don't collect personal information from anyone, this isn't a concern.

We may update this privacy policy occasionally. The "Last Updated" date at the top will reflect changes. Continued use of PoolMath Pro after changes constitutes acceptance of the updated policy.
