Terms of Use

ScreenTail (screentail.com) is run by Vivek Kumar, personally, from New Delhi, India. There is no company behind it. Contact: contact@screentail.com.

These terms apply to your use of the site. By using it you accept them. If you do not, please stop using it: there is nothing to cancel and no account to close.

Every tool is free to use, for personal or commercial purposes, with no account and no payment. You may link to any page.

You agree not to:

• try to gain unauthorized access to the site or anything connected to it;
• deliberately overload it, or interfere with its availability for others;
• scrape it at a rate that amounts to an attack rather than a visit;
• copy the site or a substantial part of it and publish it as your own, or use it for anything unlawful;
• present anything on it as a certification, inspection or professional assessment of a display.

Each tool is a web page that shows colors, patterns or moving pictures, plays sounds, runs timers, reports what your browser says about your device, or makes a file on your device. A browser cannot measure light, color, brightness, contrast, response time or delay, and each tool page says what it can and cannot show you. Nothing on this site is a calibration, a measurement or a guarantee about your display, your computer or any other device.

Results depend on your screen, its settings, your graphics driver, your browser, the room you are in and where you are sitting. Two people running the same test can honestly see different things. Manufacturers apply their own thresholds for what counts as a fault, assessed on their equipment, not yours.

Sound. The noise, sound and timer tools play sound only after you press a button. The site has no way of knowing the volume actually reaching your ears; that depends on your system volume, your hardware and your headphones. Set your volume low before starting and raise it if you need to. No health, medical or therapeutic claim is made for any sound here.

Motion. One tool flashes on purpose: the Stuck Pixel Fixer, in a small square, only after a seizure warning you must accept, and you use it at your own risk. No other tool on this site is designed to flash or strobe. Moving screens start only when you press a button, and if your system asks for reduced motion they show a still picture instead. That is not a promise that every picture suits everyone: if anything on screen makes you uncomfortable, stop and look away.

The prank screens imitate screens such as updates, crash screens and a cracked display. They are pictures drawn in a web browser. They are not real, they change nothing on the device, they touch no files, and Esc, a click or a tap closes them.

What they are for: entertainment, and props for videos.

What is not permitted: using them to deceive anyone into an action that harms them, such as paying money, handing over passwords or buying a repair they do not need, or to impersonate a company for gain.

The design, text, code and original graphics of this site belong to Vivek Kumar, except where stated otherwise. You are welcome to use the tools, link to any page, and share what you make with them: an image you make with a wallpaper tool is yours, not this site's.

The typefaces are third-party fonts, and the natural sounds are third-party recordings, each used under its own license, which governs it rather than these terms. Trademarks and product names mentioned anywhere on the site belong to their owners and are used only to describe what a tool imitates or what a company publishes; no affiliation with, or endorsement by, any of them is claimed.

Where a page links to another website, for example a manufacturer's own documentation, that site is not under this site's control, and it is not responsible for that site's content, accuracy or privacy practices. A link is not an endorsement.

There is no advertising and there are no affiliate links on the site today. ScreenTail sets no cookies and counts page views with its own simple counter, and the Privacy Policy describes what the site collects.

What ScreenTail is, and is not. ScreenTail is a website that helps you check a screen and other devices, and identify issues you may want to look into. It does not diagnose, repair or certify any hardware, and it does not promise that anything can be repaired, replaced or covered by a warranty.

Your own risk. You use the site, its tools, its guides and anything they show you entirely at your own risk, and you are responsible for any decision you make based on them.

No warranty. The site is provided "as is" and "as available", free of charge, with no warranty of any kind, express or implied, including any warranty of accuracy, reliability, availability, fitness for a particular purpose or non-infringement. There is no guarantee that it will work on your device or browser, that it is free of errors, or that any result it shows is correct. It is run by one person and may change, be interrupted or be withdrawn at any time without notice.

No liability. To the fullest extent permitted by law, Vivek Kumar is not liable for any loss or damage of any kind arising from, or connected with, your use of the site or your reliance on anything it shows, whether direct, indirect, incidental or consequential. That includes damage to hardware, lost data, lost time, lost profits, the cost of repairs or replacements, and a warranty or return claim that is refused. Because the site is free, where any liability cannot be excluded, it is limited to the smallest amount the law allows.

Nothing in these terms excludes or limits any liability that cannot be excluded or limited under the law that applies to you.

These terms may change as the site changes. When they do, the effective date at the top changes with them. Continuing to use the site after a change means accepting the revised terms.

Governing law. These terms are governed by the laws of India.

If any part of these terms is found to be unenforceable, the rest still applies.
