Using the tools
You may use the four tools for a plain white field, manual visual comparisons and approximate screen lighting. There are no visitor accounts, purchases or subscriptions. Do not attack or disrupt the service, evade access controls, obtain private files or misuse it against others.
Visual aids and their limits
These are manual visual aids, not automated hardware diagnostics, repair software, calibrated instruments, professional colour measurement or certification. Results depend on your display, device/browser settings, viewing angle and surroundings. A clear-looking field or your own observation summary is not a guarantee of display condition.
Comfort and device care
Use comfortable brightness and viewing conditions; stop or take a break if uncomfortable. Avoid prolonged static bright images. Do not press, rub, clean or attempt to repair a powered display based on these tools. Follow your exact device manufacturer’s instructions. Choose fullscreen only when wanted; Escape, tap or keyboard return controls allow you to leave, with a full-window fallback where necessary.
Availability and updates
Browser/fullscreen support varies. We may update the tools and cannot promise uninterrupted availability, compatibility with every device or error-free operation. No medical, repair, warranty or calibrated-measurement guarantee is offered.
Ownership and external material
Original site code, presentation and content belong to their applicable owners or licensors; ordinary use of the tools is permitted. This does not claim ownership of your notes or observations, or of third-party material. External websites have their own terms and privacy practices; TechneKaizen does not control them.
Responsibility and your legal rights
Use the visual aids with their stated limitations. Nothing in these terms excludes or limits liability for fraud, death or personal injury caused by negligence, or any responsibility or consumer right that cannot lawfully be excluded or limited. These terms do not waive statutory protections or impose an exclusive court/forum clause. Seek appropriate professional/manufacturer advice for a physical display concern.
Privacy and analytics choices
The Privacy & Cookies Policy explains optional GA4, necessary preference storage and hosting logs. Using this website or agreeing to these terms does not grant consent to analytics. You may decline and continue using the tools; Cookie Settings is in every footer.
Contact and changes
Contact info@technekaizen.com about these terms. The revision date changes when the terms materially change. No claim of lawyer approval or legal certification is made.
