Privacy Policy

Last updated: May 13, 2026

1. What Data We Collect

None. screenres.app is a 100% client-side application. All screen diagnostics — resolution detection, viewport measurement, DPR calculation, color depth analysis, and every other feature — are computed entirely within your web browser using standard JavaScript APIs.

We do not collect, store, transmit, or process any personal information, device information, or usage data. There is no server-side component involved in the diagnostic process.

2. Cookies & Local Storage

screenres.app does not set any first-party cookies. The only local storage used is for saving your theme preference (dark/light mode) so your preference persists between visits. This data:

• Never leaves your browser
• Contains no personal information
• Can be cleared at any time via your browser settings

Third-party advertising services (see Section 3) may set their own cookies. You can manage these through your browser settings or by visiting Google's Ads Settings.

3. Third-Party Services

Google Fonts

We load typefaces (Space Grotesk, DM Mono) from Google Fonts. When you visit our site, your browser makes a request to Google's font servers. Google's privacy policy applies to that request.

Google AdSense (Advertising)

This site may display advertisements served by Google AdSense, a third-party advertising service provided by Google LLC. Google AdSense may use cookies and web beacons to serve ads based on your prior visits to this website or other websites. You may opt out of personalized advertising by visiting Google's Ads Settings. For more information, visit Google's Privacy & Terms.

Analytics

screenres.app uses no analytics scripts (no Google Analytics, no Plausible, no Matomo, no Hotjar, nothing).

4. Data Sharing

We do not collect, sell, or share any personal data. Outside of third-party advertising cookies set by Google AdSense (which you may opt out of), there are no data processors, data brokers, or business partners who receive your information.

5. Children's Privacy

screenres.app does not knowingly collect any information from anyone, including children under the age of 13. Since no personal data is collected from any user, this tool is safe for use by all ages.

6. GDPR & CCPA Compliance

Because screenres.app collects no personal data:

• There is no data to access, rectify, delete, or port under GDPR
• There is no personal information sold or disclosed under CCPA

If you wish to opt out of third-party advertising cookies, visit Google's Ads Settings.

7. Security

All pages are served over HTTPS. We implement a Content Security Policy (CSP) header to prevent cross-site scripting attacks. The site contains no forms, no file uploads, and no user input that is transmitted to a server.

8. Changes to This Policy

If we ever change our data practices, we will update this page with a new "Last updated" date.
