Terms of Use

Last updated: 10 November 2026

By using CRC Calculator at crc.runkodo.com ("the site") you agree to these terms. If you do not agree, please do not use the site.

The service

The site provides free online tools for calculating CRCs, checksums and hashes, together with reference material about them. No account is needed. We may change, add or remove tools at any time.

Accuracy and intended use

The calculators are tested against published check values, and we work to keep the reference material correct. Even so, the site is provided "as is", without warranty of any kind, express or implied, including fitness for a particular purpose.

Do not rely on the site as the only verification for safety-critical, medical, automotive, industrial-control or financial systems. Confirm results against the relevant standard, datasheet or a second independent implementation before using them in such systems.

CRCs and simple checksums detect accidental errors only. Nothing on this site should be taken as advice that they provide security against deliberate tampering.

Generated code and content

Source code produced by the calculators' code generators, and the short code samples shown on the pages, may be used, copied and modified freely in your own projects, including commercial ones, without attribution. It is provided without warranty.

The remaining text, design and layout of the site may not be republished in bulk without permission.

Acceptable use

Please do not attempt to disrupt the site, overload it with automated requests, or interfere with other people's use of it.

Advertising and external links

The site shows advertisements supplied by third parties and links to external websites. We do not control and are not responsible for the content of those advertisements or sites. How advertising cookies are used is described in the Privacy Policy.

Limitation of liability

To the fullest extent permitted by law, the operator of the site is not liable for any loss or damage arising from the use of, or inability to use, the site or the results and code it produces.

Changes to these terms

These terms may be updated from time to time. The date at the top of the page shows when they last changed; continuing to use the site after a change means you accept the updated terms.

Questions about these terms can be sent to support@runkodo.com.
