Privacy Policy

Last updated: 20 April 2026

Short version: the tests themselves run locally in your browser. We do not require an account, and we do not ask you to upload photos, screenshots or diagnostic files to use the site. The main personal-data touchpoints are Cloudflare/security and hosting logs, external asset requests, Google Analytics 4, Google AdSense / Funding Choices, and any third-party sites you choose to click through to, including Amazon affiliate links.

1. Who we are

ScreenTester.uk is operated by INLine Computers. If you have privacy questions, contact [email protected].

2. What the site does locally in your browser

Most of the site's functionality is rendered client-side using standard browser APIs such as HTML5 Canvas, pointer/touch events, fullscreen APIs and limited device capability checks. Your drawings, touch activity and screen checks stay on your device unless you deliberately export something locally, such as a CSV from the refresh-rate test.

3. What information may be processed

Cloudflare / security and delivery data: ScreenTester.uk uses Cloudflare as a reverse proxy, CDN and security provider. Cloudflare may process IP address, traffic routing data, user agent, requested URL, referrer, status code and other request metadata to cache content, route traffic and protect the site from malicious or abusive traffic.
Basic origin-hosting logs: our hosting provider may also record technical request information such as IP address, user agent, time, requested URL, referrer and status code for security, troubleshooting and abuse prevention.
External asset requests: pages request fonts or CSS from providers such as Google Fonts and jsDelivr. Those providers can see technical request data such as your IP address, browser and the page requesting the asset.
Analytics data: we use Google Analytics 4 to understand which pages and tests are useful. Google states that Analytics does not log or store individual IP addresses from EU users and uses EU-user IP data only for coarse geo-location derivation before discarding it.
Advertising and consent data: we use Google AdSense together with Google Privacy & messaging / Funding Choices and Consent Mode v2. When Google services load, your browser may automatically send information such as the page URL and IP address to Google, and Google may set or read cookies and similar technologies depending on the service and your consent choices.
Affiliate links: some pages include affiliate links, including Amazon links. If you click one, the destination site receives your request directly and may use cookies, identifiers or other attribution technologies under its own privacy and cookie notices. If you buy something after clicking a qualifying affiliate link, we may receive a commission at no extra cost to you.
Correspondence data: if you email us, we receive the contact details and message content you choose to send so that we can respond.

4. Cookies, consent and privacy controls

For visitors in the UK, EEA and Switzerland, ScreenTester.uk uses Google Privacy & messaging / Funding Choices together with Consent Mode v2. Ad-related and analytics-related consent defaults are denied in those regions until Google records the visitor's choice.

If you refuse consent, Google services should remain in a restricted mode for the affected consent types. Outside those regions, Google services may run without the same consent prompt, depending on local law and product settings.

Cloudflare may also set strictly necessary security or traffic-management cookies when its protection or traffic-management features require them. Those cookies are used to help deliver and secure the site rather than for advertising or optional analytics.

You can also review the relevant third-party notices here:

5. Why we use information and our lawful bases

Legitimate interests: to secure the site, prevent abuse, keep the service available, diagnose faults, and understand broad product performance where this does not rely on consent.
Consent: for analytics storage, ad storage, ad user data and ad personalisation where consent is required by applicable law.

6. Who data may be shared with

Cloudflare, which we use for CDN, proxying and security.
Google services that we use, such as Google Analytics 4, Google AdSense and Google Privacy & messaging / Funding Choices.
Infrastructure and asset providers such as our hosting provider, Google Fonts and jsDelivr.
External services that you choose to click through to, such as Amazon or other linked sites.

7. International transfers

Some third-party services we use may process technical data outside the UK, including in the United States or other countries where they operate. For example, Cloudflare states that by default certain cookie data may be processed in the United States, and Google and Amazon may also process data internationally. Where this happens, those providers are responsible for the transfer mechanisms and safeguards described in their own privacy documentation.

8. Retention

We aim to keep operational logs only for as long as necessary for security and troubleshooting. Cloudflare and our hosting provider apply their own operational logging settings. For Google Analytics 4, retention is controlled within that product's account settings and policies. Third-party destinations such as Amazon apply their own retention periods under their own notices. We do not operate user accounts, private dashboards or uploaded-file storage on ScreenTester.uk.

9. Your rights and choices

Use the consent prompt or the Privacy & cookie settings link to review or change consent choices where the Google message applies.
Use your browser settings to block or clear cookies and site data.
Use private browsing or close the tab to end the local test session.
Use Google Ads Settings, Google My Ad Center or Amazon's own privacy / cookie settings if you want to change how those services use your data.
If UK GDPR applies, you may have rights such as access, rectification, erasure, restriction, objection and complaint to the ICO.

10. Complaints and contact

If you have a privacy question or believe something on the site is inaccurate, email [email protected]. If you are in the UK and believe your data has been handled unlawfully, you can also complain to the Information Commissioner's Office (ICO).
