Agreement To These Terms

These Terms of Use ("Terms") are an agreement between you and Screen Tester ("we", "us" or "our"), the operator of screentester.co. They apply whenever you visit the site or use any of its screen tests, tools, guides or contact form (together, the "Service").

By using the Service, you agree to these Terms. If you do not agree, please do not use the Service.

You must be at least 13 years old to use the Service. If you are under the age of majority where you live, please use it with the involvement of a parent or guardian.

Using Our Tools

Subject to these Terms, we give you a free, personal, non-exclusive, non-transferable and revocable permission to use the Service. In practice, that means you can:

  • Use any test or tool on your own screens and devices, for personal or business purposes
  • Use the tools in a shop, office, school or repair workshop to check devices for customers or colleagues
  • Take screenshots and photos of results, and keep or share the reports and images you download
  • Link to any page on screentester.co from your website, social media or messages

The Service is free and requires no account. We may limit or end access for anyone who breaks these Terms.

What You Must Not Do

To keep the Service free, safe and working for everyone, you agree not to:

  • Copy, scrape, mirror or republish the site, its tools, code, test patterns or written content, or offer them as part of another product or service
  • Embed our pages in frames or apps in a way that hides our branding or presents the tools as your own
  • Sell, rent or charge others for access to the Service
  • Use bots, scripts or automated requests that place an unreasonable load on our servers
  • Try to hack, probe, disrupt or bypass the security of the Service, or upload malware
  • Remove or change any copyright, trademark or other notice on the site
  • Present our test results as a certified laboratory measurement, or use them to mislead buyers, sellers or manufacturers
  • Use the Service for anything unlawful, or to harm, harass or deceive anyone

If you would like to use our content or tools in a way not allowed here, for example in a publication or a commercial product, please contact us first.

Health And Safety Warnings

Some tools show rapidly flashing colors, bright full screen light or loud sounds. Use them with care, and stop if you feel unwell.

  • Photosensitive epilepsy: the Stuck Pixel Fixer and some motion and flicker tests flash rapidly. Do not use them if you, or anyone who can see the screen, has photosensitive epilepsy or is sensitive to flashing light. Use the gentle, no-flash options where offered.
  • Eye comfort: bright white or full screen patterns in a dark room can cause glare and eye strain. Lower the brightness and take breaks.
  • Hearing: start speaker and audio tests at a low volume, especially with headphones, and raise it gradually.
  • Your device: never press, rub or open a screen because of a test result. Physical "fixes" can crack the panel and void the warranty.

You use the tools at your own risk and are responsible for using them safely.

Test Results And Accuracy

Our tests are designed to make screen faults easy to see, and we work hard to keep our guides accurate. However:

  • Results are a visual guide, not a certified laboratory measurement made with professional equipment.
  • What you see depends on your device, browser, operating system, settings, room lighting and eyesight.
  • Measured values, such as refresh rate or frame rate, come from your browser and may differ from the hardware specification.
  • We do not guarantee that a seller, retailer or manufacturer will accept our results for a return, exchange or warranty claim. Their own policies decide that.
  • Screen Tester is independent and is not affiliated with, or endorsed by, any screen, device or software maker mentioned on the site.

Decisions you make based on our tests or guides, such as keeping, returning or repairing a device, are your own. See our Disclaimer for more.

Your Messages And Feedback

  • When you send us a message, you confirm that the information is yours to share and does not break anyone else's rights.
  • We use your message to reply to you and to improve the Service, as described in our Privacy Policy.
  • If you send ideas, suggestions or feedback, such as a tool request, we may use them freely to improve the Service, without any obligation or payment to you.
  • Please do not send confidential information, passwords or payment details through the contact form.

Intellectual Property

The Service and everything on it, including the text, guides, tools, code, test patterns, designs, graphics, logos and the Screen Tester name, are owned by Screen Tester or its licensors and are protected by copyright, trademark and other laws.

  • You may quote short extracts of our guides with clear credit to Screen Tester and a link to the original page.
  • All other use, including copying whole pages, tools or patterns, needs our written permission.
  • Other brand names, product names and trademarks mentioned on the site belong to their owners and are used only to identify those products.

Availability And Changes To The Service

We aim to keep the Service available and working well, but we do not promise that it will always be available, uninterrupted, error-free or compatible with every device and browser. We may add, change, suspend or remove any tool, page or feature at any time, with or without notice.

Disclaimer Of Warranties

The Service is provided free of charge, "as is" and "as available", without warranties of any kind, whether express or implied.

To the fullest extent allowed by law, we disclaim all warranties, including implied warranties of merchantability, fitness for a particular purpose, accuracy and non-infringement. We do not warrant that the Service or its results will meet your needs or be free of errors, viruses or other harmful components.

Limitation Of Liability

To the fullest extent allowed by law, Screen Tester and its team will not be liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of profits, data, goodwill or use, arising from or related to your use of, or inability to use, the Service. This includes decisions made based on test results and any effect on your device.

Because the Service is free, our total liability for any claim relating to the Service is limited to 100 US dollars (USD 100).

Some places do not allow certain warranties to be excluded or liability to be limited. In those places, these limits apply only as far as the law allows, and nothing in these Terms affects rights you have that cannot be waived by contract.

Indemnity

You agree to defend, indemnify and hold harmless Screen Tester and its team from any claims, losses, damages and costs, including reasonable legal fees, arising from your misuse of the Service or your breach of these Terms.

Governing Law And Disputes

  • These Terms are governed by the laws of the State of California, United States, without regard to its conflict of law rules.
  • If you have a concern, please contact us first. We will try to resolve it informally within 30 days.
  • If a dispute cannot be resolved informally, it will be handled by the state or federal courts located in Los Angeles County, California, and you and we agree to their jurisdiction.
  • If you are a consumer living in the EEA, the UK or another country with mandatory consumer protection laws, you keep the protections of those laws and may bring claims in your local courts.

Changes To These Terms

We may update these Terms from time to time. When we do, we will change the Last updated date at the top of this page, and for important changes we will add a clear notice on the site. If you keep using the Service after changes take effect, you accept the updated Terms.

General Terms

  • Entire agreement: these Terms and the policies linked above are the whole agreement between you and us about the Service.
  • Severability: if any part of these Terms is found unenforceable, the rest stays in effect.
  • No waiver: if we do not enforce a term straight away, we can still enforce it later.
  • Assignment: you may not transfer your rights under these Terms. We may transfer ours, for example if Screen Tester is reorganized or sold.
  • Headings are for convenience only and do not change the meaning of the Terms.
