Terms & Privacy

How you may use this service, what we don’t guarantee, and how we handle data. This is plain-language information—not a substitute for legal advice.

This website and service are offered at perimeter-check.com (https://perimeter-check.com/).

Terms Of Use

By using Perimeter (“the service”), you agree to the following.

  • What the service is. A read-only tool that gathers publicly visible information about domain names and related infrastructure (for example DNS, TLS, HTTP headers, mail-related DNS, and high-level website signals). It produces reports and optional tools (such as Open Graph previews) for your own review.
  • What it is not. Not a penetration test, guaranteed security audit, or compliance certification. Outputs are informational and may be incomplete or out of date.
  • Authorized use only. Use the service only for domains and systems you own or are explicitly authorized to assess. Do not use it to harass others, overload third-party systems, or probe assets without permission.
  • No warranty. The service is provided “as is” without warranties of any kind. We do not guarantee accuracy, availability, or fitness for a particular purpose.
  • Limitation of liability. To the maximum extent permitted by law, we are not liable for any damages arising from your use of the service or reliance on its outputs.
  • Changes. We may update these terms or the product from time to time. Continued use after changes means you accept the updated terms. We’ll reflect material changes on this page.

Data Retention & Privacy

  • No accounts — you don’t need to sign up. We don’t keep a searchable history of every scan as a core product feature.
  • Session-scoped reports — your current report is tied to your browser session so you can open, refresh, and export it during your visit.
  • Short-lived server cache — we may write a temporary file so report links work reliably right after a scan. This is not a permanent archive.
  • Automatic expiry — we remove on-disk report data about 12 hours after scan completion. After that, the URL will show as unavailable.
  • When access ends — if your session ends, cookies are cleared, or the cache expires, the same link may stop working. Download PDF, JSON, or CSV while you still have access if you need to keep results.
  • Logs & abuse protection — we may keep minimal operational logs (for example rate limits, errors, or coarse scan metrics) to operate the service safely. We don’t sell personal data.

For definitions of technical terms in reports, see the Glossary.

UK GDPR (Personal Data)

Where the UK GDPR applies, we aim to process personal data lawfully, fairly, and transparently. Depending on how you use the service, we may process personal data such as: network identifiers (for example IP addresses in server logs), session identifiers, information you submit (such as a domain or URL to scan), and report content generated for you.

We may rely on lawful bases including: providing the service you request (the scan and report), legitimate interests in running and securing the service and preventing abuse (balanced against your rights), and where applicable legal obligations.

Under the UK GDPR you have rights including: access to your personal data, rectification, erasure in certain cases, restriction of processing, data portability where applicable, and objection in certain circumstances. You may also lodge a complaint with the UK Information Commissioner’s Office (ico.org.uk). How you can exercise these rights in practice depends on what data we hold and whether we can identify you (for example from logs); for questions about this service, use the information published on About or contact details listed on https://perimeter-check.com/. This summary is not legal advice.

Cookies & Browser Storage

Cookies are small pieces of data your browser stores and sends back to a site on later requests. We use them sparingly and only for our own site (first‑party)—not for advertising networks or cross‑site tracking.

  • Session cookie (name: __Secure-dss_sess). This lets the server maintain a PHP session so we can: protect forms with CSRF tokens, associate your scan and report with this browser visit, and support flows such as loading a report after a scan. It is not used to profile you across the web.
  • What we don’t do. We do not set third‑party advertising cookies, social “pixels,” or analytics cookies for tracking you across sites.
  • Theme (not a cookie). If you choose light or dark mode, we save that choice in your browser’s local storage under the key dss-theme. That stays on your device and is not sent to our server on every request like a cookie.
  • Dismissing the cookie notice. If you use “Got it” on the site notice, we remember that in local storage (dss-cookie-notice) so we don’t show the same banner again on this device.

Cookie & storage list

The table below lists first‑party cookies and similar browser storage we use. (ICO guidance often recommends a clear list alongside a short policy.)

Name Type Purpose Duration
__Secure-dss_sess HTTP cookie (first‑party) PHP session: CSRF protection, linking scans and reports to your visit Session (until you close the browser or clear cookies)
dss-theme Local storage Stores light or dark theme preference Until you clear site data for this origin
dss-cookie-notice Local storage Remembers that you dismissed the cookie notice Until you clear site data for this origin

In the UK, use of cookies and similar technologies is mainly governed by the Privacy and Electronic Communications Regulations (PECR), alongside the UK GDPR where personal data is involved. The ICO (Information Commissioner’s Office) distinguishes strictly necessary cookies—typically those essential to deliver a service you request here, such as security and session handling—from non‑essential cookies (for example many analytics or marketing cookies); consent requirements generally differ between those categories. EU countries apply similar principles under national implementations of the ePrivacy rules and the GDPR, but the details are not identical to the UK. We do not use non‑essential cookies for advertising or cross‑site analytics on this service. Laws in other countries vary. This page is for transparency, not legal advice; consult your own counsel if you need certainty for your situation.

You can clear cookies and site data in your browser settings; removing the session cookie may end the current visit’s session and require a new scan or fresh report link behavior until a new session is established.
