1. Privacy Summary

At Screen Sizes Calculator (screensizescalculator.com), your privacy is our primary engineering consideration. We designed our calculators to work completely inside your web browser. We do not require accounts, logins, email submissions, or personal details to use any tool on this site.

Key Takeaway

We do not collect, sell, lease, or monetize your personal data. We do not profile visitors across the web, nor do we run cross-site tracking pixels.

2. Client-Side Calculation Processing

All calculations performed on Screen Sizes Calculator—such as screen diagonals, aspect ratios, custom dimension inputs, viewing distances, room measurements, and pixel densities—are executed exclusively by your device's browser using client-side JavaScript.

No numbers, dimensions, or device preferences typed into our calculator inputs are ever transmitted over the network to our servers or third parties.

3. Cookies and Browser Local Storage

We do not use tracking cookies, advertising beacons, or profiling cookies.

We use browser localStorage solely for functional interface preferences:

  • Key: theme — Stores either "dark" or "light" so that your preferred visual theme persists between page visits and prevents screen flashing.

This key contains no personal or identifying information. You can clear this data at any time through your web browser's storage settings.

4. Server Logs and CDN Delivery

When you visit any website, standard automated log files are recorded by hosting providers and Content Delivery Networks (CDNs).

These logs may include:

  • Internet Protocol (IP) address (often anonymized or truncated)
  • Browser type and operating system user-agent
  • Date and timestamp of request
  • Referring / exit pages
  • HTTP status code and response size

This technical diagnostic data is processed strictly for infrastructure security, automated threat detection, DDoS defense, and ensuring network uptime. It is not joined with any personal identities.

5. Third-Party Services & Assets

To provide crisp typography and fast asset delivery, we utilize reliable public Content Delivery Networks:

  • jsDelivr CDN: We load the Geist typeface font files (WOFF2) via jsDelivr. When your browser requests font assets, jsDelivr receives the standard HTTP request header. For more details, consult the jsDelivr Privacy Policy.

6. GDPR, UK DPA & CCPA/CPRA Compliance

Depending on your location, data protection frameworks such as the General Data Protection Regulation (GDPR) and California Consumer Privacy Act (CCPA/CPRA) grant specific privacy rights:

  • Right to Know & Access: The right to confirm whether personal data is processed.
  • Right to Deletion: The right to request erasure of personal data.
  • Do Not Sell or Share My Personal Information: We do not sell, trade, or share personal information with data brokers or marketing affiliates.

Because we do not collect personal identifiers, emails, or user accounts, we generally hold no personal records tied to individual identities.

7. Children's Online Privacy Protection (COPPA)

Our calculators are general interest educational and utility tools suitable for all ages. We do not knowingly collect or solicit personal information from children under the age of 13. If you believe a child has provided us with personal information, please contact us immediately.

We may occasionally update this Privacy Policy to reflect technical adjustments or evolving legal requirements. Changes take effect upon posting to this URL.
