Terms of Use
These Terms of Use ("Terms") are an agreement between you and Luke Mckeever, an individual ("we", "us"), who runs ARACHNE (the "Service"). By creating an account or using the Service you agree to them. If you don't agree, don't use the Service.
1. What the Service is
ARACHNE is an indicator-of-compromise (IOC) scanner and open-source intelligence (OSINT) tool. You enter an indicator, such as an IP address, domain, URL, email address, username or file hash, and the Service asks third-party data sources about it and shows you their answers. The Service is provided free of charge.
2. Who can use it
- You must be at least 18 years old.
- Access is by approval. We can approve or refuse any request without giving a reason.
- If you use the Service for an organisation, you confirm you're allowed to accept these Terms for it, and "you" includes that organisation.
- Keep your password safe and don't share your account. Tell us straight away at info@arachne-app.site if you think someone else has used it. You're responsible for what happens under your account.
3. Acceptable use
You may use the Service only for lawful, legitimate purposes such as security research, threat intelligence, incident response, fraud prevention, and protecting your own systems, accounts or organisation. You must not use it to:
- break any law, including data protection law (such as the GDPR), computer misuse, anti-hacking, harassment and anti-stalking laws;
- stalk, harass, intimidate, dox, discriminate against, or otherwise harm any person, or build profiles of private individuals without a lawful basis;
- look up email addresses, usernames or other personal data of people in a way that would disadvantage them, or to market to or contact them based on the results;
- scan, probe or test systems, networks or websites you don't own or have permission to test (this matters most for active modules, which contact the target directly);
- attack, overload or disrupt the Service or any data source, get around usage limits or access controls, or use automated tools to make bulk requests beyond what the Service offers;
- use the Service or its results in breach of a data source's own terms, including sources that allow only non-commercial use (see Copyright and notices);
- resell, sublicense or provide the Service to others as a commercial product, or use results to build a competing database;
- upload or send anything malicious, unlawful, or that infringes someone else's rights.
Personal data you look up is your responsibility. When you search for indicators that relate to a person (such as an email address or username), you decide why and how that data is processed, so you are responsible for having a lawful basis and for complying with data protection law. Don't make decisions that significantly affect a person based only on results from the Service.
4. Your API keys
Some sources need your own API key. Keys are stored in your browser and sent to the Service only to make the lookup you asked for; the Service doesn't store them. You're responsible for your keys and for following each provider's terms and limits.
5. Results and third-party data
Results come from independent third parties and are shown "as is". They can be incomplete, out of date, wrong, or contain false positives. Verdicts and risk scores are automated indications, not facts or professional advice. Check important findings yourself before you rely on them. We don't control the data sources, aren't responsible for their content or availability, and aren't affiliated with or endorsed by them. Their content belongs to them and is covered by their own terms.
6. Our content and the software
The ARACHNE software is open source under the MIT licence (see Copyright and notices). The site's own content, branding and the compilation of the Service are © 2026 Luke Mckeever. Nothing in these Terms limits the rights the open-source licences give you.
7. Availability, limits and changes
The Service is free and offered on a best-effort basis. We may change, limit, suspend or stop the Service, or any feature or data source, at any time, and we may set usage limits. We aim to give notice of major changes where we reasonably can.
8. Suspension and termination
You can stop using the Service and delete your account at any time from your Account page. We may suspend or end your access at any time, including without notice if you breach these Terms, if we're required to by law, or to protect the Service, its users, data sources or third parties. Sections 5, 9, 10, 11 and 13 continue to apply after your access ends.
9. No warranty
To the fullest extent permitted by law, the Service is provided "as is" and "as available", without warranties of any kind, express or implied, including fitness for a particular purpose, accuracy, non-infringement, or that it will be uninterrupted, secure or error-free.
10. Limitation of liability
- To the fullest extent permitted by law, we are not liable for any indirect or consequential loss, or for any loss of profits, revenue, business, data, goodwill or opportunity, arising from or in connection with the Service.
- To the fullest extent permitted by law, our total liability to you for all claims in connection with the Service is limited to €100.
- Nothing in these Terms excludes or limits liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or any other liability that cannot be excluded or limited under applicable law.
- If you are a consumer, nothing in these Terms affects your statutory rights, and the limits above apply only as far as the law allows.
11. Indemnity
If you use the Service for business or professional purposes, you agree to indemnify us against claims, losses and costs (including reasonable legal fees) brought by third parties that arise from your breach of these Terms or your unlawful use of the Service or its results. This section doesn't apply to consumers.
12. Changes to these Terms
We may update these Terms. The version and date are shown at the top of this page. If we make a material change, we'll ask you to accept the new version the next time you sign in; if you don't accept it, you can stop using the Service and delete your account.
13. Governing law and disputes
These Terms are governed by the laws of Ireland, and the courts of Ireland have jurisdiction. If you are a consumer living elsewhere in the European Union, you also keep the protection of the mandatory laws of your country, and you can bring proceedings in your local courts.
14. General
If any part of these Terms is found invalid, the rest stays in force. If we don't enforce a right straight away, we haven't given it up. You can't transfer your rights under these Terms; we may transfer ours to someone who takes over the Service, without reducing your rights. These Terms, the Privacy Policy and the Cookies notice are the whole agreement between us about the Service.
