Please use the contact method provided on this page for corrections, bug reports, broken links, and tool requests.
When reporting a problem, please include the page name and a short description of what happened.
Good reasons to get in touch include:
- A tool gives an incorrect, confusing, or buggy result.
- An article, worked example, or historical detail contains a factual mistake.
- A cipher rule, formula, or glossary definition needs improving.
- A link is broken, or a page behaves strangely on mobile or desktop.
- You want to request a new cipher, encoding, or cryptography topic.
If you are reporting a tool problem, it helps to include the page name, what you typed in, what result you expected, and what result you actually got.
Privacy
This site is designed to ask as little from visitors as possible. You can use the tools and read the articles without creating an account, logging in, or submitting personal details.
Tool Input
Most interactive tools on this site run directly in your browser. The tools are designed to process ordinary input locally on your own device rather than sending your message away for processing.
Even so, you should never type sensitive real-world secrets, passwords, private keys, financial details, medical information, or confidential material into educational web tools.
Basic Website Information
Like almost all websites, the site or its hosting provider may process basic technical information needed to serve pages securely. This can include:
- IP address
- Browser type
- Device type
- Pages visited
- Time of access
- Referring page
This kind of information is used for security, reliability, diagnostics, and basic site operation.
Analytics, Cookies & Third-Party Services
If analytics are used, they are intended only to help us understand general site usage, such as which pages are useful and where improvements are needed. Analytics are not intended to collect the text you type into cipher or encoding tools.
Cookies, local storage, or similar technologies may be used by services such as analytics, advertising, donation platforms, sharing tools, or basic site preferences.
If advertising is used, providers may use cookies or similar technologies according to their own policies and the consent choices available on the site.
If you use an external service linked from this site, such as Ko-fi, its own privacy policy applies once you leave the site.
Donations
Donations are optional and are handled externally through Ko-fi. The tools are meant to remain free and useful whether or not someone contributes financially.
If you choose to donate, you will be taken to Ko-fi's website. Ko-fi and its payment providers handle the transaction. This site does not process or store card or payment details directly.
Donations help support the time spent building, testing, writing, improving, and maintaining the site. A donation does not create a paid support relationship or guarantee that a specific feature, article, or tool will be added.
Accuracy & Limitations
This site aims to be careful, readable, and technically honest. However, mistakes can happen.
Historical explanations may simplify complex stories. Worked examples may contain errors. Tools may have bugs or edge cases. Glossary definitions may need sharpening.
Corrections are welcome, especially for:
- Cipher rules
- Formulas
- Worked examples
- Historical details
- Glossary entries
- Tool behaviour
- Broken links
- Unclear explanations
- Layout or accessibility problems
If something looks wrong, unclear, or misleading, please report it. Corrections are genuinely useful and help improve the site for everyone who arrives later.
Educational Use & Security Warning
The tools and articles on this site are provided for learning, puzzles, experimentation, historical interest, and technical understanding.
Classical Ciphers Are Not Secure
Many of the classical ciphers covered here, including Caesar, Affine, Vigenere, Playfair, Rail Fence, ADFGX, ADFGVX, and Bacon's cipher, are not secure by modern standards. They are excellent for education and exploration, but they should never be used to protect sensitive real-world information.
Modern Cryptography
Modern cryptography demonstrations on this site should also be treated as educational unless a page clearly says otherwise. They are designed to explain ideas, not to replace professional security software, operational security guidance, legal advice, or compliance advice.
Terms of Use
Please use the site thoughtfully and responsibly. You should not use the tools or content for unlawful activity, harassment, abuse, deception, or attempts to compromise other people's systems or accounts.
The site is provided for education, experimentation, and general learning. It is not a substitute for professional security software, legal advice, compliance advice, or operational security guidance.
The site and its tools are provided as-is and without warranty. Although we aim to make the tools and explanations accurate, we cannot guarantee that every result, article, formula, historical note, or example is complete, current, or error-free.
You should verify important details independently, especially where accuracy matters for security, legal, educational, professional, or operational reasons.
Site Changes
The site is a living project. Tools, articles, layouts, policies, links, and features may be updated, removed, replaced, or reorganised over time.
External Links
Some pages link to external resources such as reference material, Ko-fi, documentation, or sharing services. Those websites are governed by their own terms, privacy policies, cookies, availability, and security practices.
A link is included because it may be useful, not because this site endorses or controls what happens after you leave it.
