Terms of use

CZNull offers browser pages for hashing, encoding, JSON, identifiers, passwords, calculators, and GPU tests. You may use them for your own work, learning, and troubleshooting, subject to this page and the disclaimer.

We may change, add, or remove pages without notice. A URL you bookmarked may move; where we know the old path, we try to send you to the new one.

You are responsible for what you paste, generate, and copy onward. Do not paste secrets you are not willing to have on that device. Tool and test work runs in your browser. You still decide where a result goes next.

If a checksum, encoding, UUID, password, or figure does not match another system, check settings on the page (encoding, HMAC, UUID version, rounding) before treating either side as wrong. Published results are informational. See the disclaimer.

GPU tests can raise temperature, fan speed, and battery use. You choose whether to start a run, which preset to use, and when to stop. You are responsible for following workplace, school, or warranty rules about stressing hardware.

Do not run a heavy test unattended on a device that cannot shed heat. Stop if the machine is uncomfortably hot. We are not liable for hardware damage, data loss, or downtime from a test you started.

Do not try to disrupt the site, scrape it in a way that harms other visitors, or use the pages to break the law. Do not use generated passwords or encodings to attack accounts or systems you do not own or are not allowed to test.

Automated access that ignores load or repeats GPU tests against the public site in a way that interferes with others is not allowed.

Text, layout, branding, and other material on CZNull belong to CZNull or to licensors, except where a page states otherwise or the law allows reuse (for example, quoting a short passage). Algorithms such as MD5 or SHA-256 are public standards; naming them does not mean those designers endorse CZNull.

You may not copy the site as a competing catalog or strip pages of attribution and republish them as your own product.

Pages are provided as they are. We do not warrant that a hash will match a third-party checksum you did not fully specify, that a GPU figure is repeatable, or that the site will be available at every moment. The disclaimer states the limits in plain language.

To the extent the law allows, CZNull is not liable for lost data, lost profits, device damage, or other losses from using or being unable to use the site, including GPU tests you ran and values you copied into other systems.

Some places do not allow certain limitations. In those places, our liability is limited to what the law requires.

We may update these terms. The date at the top will change. If you keep using the site after an update, the new terms apply to later use.
