Last updated: 5 November 2026

The tools, calculators and guides on CodeBySDE (https://codebysde.in) are provided for general information and convenience. Please read the notes below before you rely on them.

Provided as is

We work to keep the tools correct and the guides accurate, but we do not guarantee that every result is complete, current or free of errors. Tools are provided as is and as available, without warranties of any kind. Always check important output yourself, especially before using it in production systems, contracts, filings or anything that is hard to undo.

Not professional advice

• Security: the password, hash, JWT and encoding tools and guides explain concepts and help with everyday tasks. They are not a security audit. Decoding a token does not verify it, and encoding is not encryption.
• Marketing and business: calculators such as A/B test significance, ROAS, LTV and CAC give estimates from the numbers you enter. Real results depend on your data, your market and how a test was run. They are not financial or business advice.
• Network and system settings: examples for chmod, cron and CIDR are explained for learning. Test changes in a safe environment before applying them to a live server or network.
• SEO: search engines do not publish their ranking rules. Suggestions about titles, descriptions and redirects are good practice, not a promise of ranking or traffic.

Your input and your responsibility

Most tools run in your browser and do not send what you enter to us, but a few, such as the Redirection Checker, make a request from our server. Do not enter passwords, private keys or other secrets into any online tool unless you need to. You are responsible for the data you enter and for how you use the output. See our Privacy Policy for details.

External links and third-party services

Some pages link to other websites or use third-party services, such as Google Analytics, Google AdSense, Google Fonts and Cloudflare. We do not control those sites or services and are not responsible for their content or practices. Our Cookie Policy explains the cookies involved.

Advertising and support

CodeBySDE is free to use. It shows ads from Google AdSense and accepts optional support through Buy Me a Coffee to help cover hosting and development. Ads and support do not change how the tools work or what the guides say.

Limitation of liability

To the extent allowed by law, CodeBySDE and its author are not liable for any loss or damage that comes from using, or being unable to use, the tools, guides or any information on this site. This does not limit any rights you have under the law that cannot be excluded. The Terms and Conditions set out the full terms of use.
