Disclaimer

Last updated 15 October 2026. Back to the home page.

This disclaimer applies to this website and to every other site in the same network linked in the footer, including all pages, articles, code, tools, data and downloads on them (together, "the site"). By using the site you accept these terms. If you don't accept them, please don't use the site.

Information and education only

Everything on the site is published for general information and education. It may be incomplete, out of date, or wrong, and it may change or be removed at any time without notice.

No warranty

The site and everything on it are provided "as is" and "as available", without any warranty of any kind, express or implied, including warranties of accuracy, completeness, merchantability, fitness for a particular purpose, title, and non-infringement. Code and configuration examples are untested for your situation; review them yourself before running them, and use them at your own risk.

Limitation of liability

To the fullest extent the law allows, the site's owner and contributors are not liable for any loss or damage of any kind arising from or connected with your use of, or reliance on, the site. That includes direct, indirect, incidental, special, consequential and punitive damages, lost data, lost profits, downtime, hardware damage and legal costs, even if we were told such damage was possible. Where the law does not allow a limit this broad, our liability is limited to the smallest amount the law permits.

Not professional advice

Nothing on the site is legal, financial, tax, medical, engineering, security or other professional advice, and reading it does not create any professional or client relationship. For decisions that matter, consult a qualified professional who knows your circumstances.

Security and radio research: authorized, lawful, defensive use only

Material about security, hacking, scanning, vulnerabilities, radio reception, signal decoding and similar subjects is shared to help people understand and defend their own systems. Use it only on systems, networks, devices and signals you own or have explicit written permission to test or monitor, and only where doing so is lawful.

We do not condone and are not responsible for any misuse of the material.

You are responsible for following the law

You are solely responsible for how you use the site and for complying with all laws and regulations that apply to you, including computer misuse, privacy, wiretap and communications, radio licensing, export control and intellectual property laws, wherever you are.

Third-party links and content

Links to other websites, services, products or projects are provided for convenience. We don't control them, don't endorse them by linking, and aren't responsible for their content, security, availability or practices. Trademarks and product names belong to their owners and are used only to identify them.

Personal views

Opinions on the site are the author's own personal views. They do not represent any employer, client, customer or other organization, and they may change.

Privacy

Visits are logged as described in the note at the bottom of each page.

Changes and severability

This disclaimer may be updated at any time; the date at the top shows the latest version. If any part of it is found unenforceable, that part is limited to the minimum extent necessary and the rest stays in effect.

Provided as is, for information only, with no warranty and no liability. Not legal or professional advice. Security and radio material is for authorized, lawful use only. Full disclaimer.

Visits are logged on our own server: IP address, browser and device details, and pages viewed. We use them to understand traffic and spot attacks, and never share or sell them.
