Last updated: 9 October 2026

downcheck.io is a free, on-demand reachability checker. You enter a web address, our server makes an ordinary HTTP request to it, and we report what came back. This page explains the rules for using the service and what happens to the data involved. It describes what this specific service actually does — not a generic template.

Terms of Service

1.Using the service

By using downcheck.io you agree to these terms. If you do not agree with them, please do not use the site.

2.What the service does

Each check makes up to three ordinary HTTP GET requests from our server to the address you entered, with a short pause in between, and reports the HTTP status, the response time and any redirects. It is a snapshot, not a monitoring service: there are no accounts, no schedules, no alerts and no long-term history.

3.Acceptable use

Use this to find out whether a public website is reachable. Do not use it to attack, overload or stress-test anything, to scan networks or ports, to probe systems you do not have permission to look at, or as part of an automated scraping pipeline. We refuse internal and private addresses ourselves and we rate-limit per visitor. If the service is abused we may block a visitor or an address range.

4.No warranty

The service is provided “as is”. A result is what our single server observed at that moment. Firewalls, bot protection, geo-blocking, rate limits on the target side and temporary network problems can all change the outcome. Do not treat a result as proof that a site is up or down, and do not rely on it as the only source for a decision that matters.

5.Limitation of liability

To the extent permitted by law, we are not liable for any damage arising from the use of this service or from reliance on a result it produced.

6.Advertising and third parties

The site may display advertising — for example Google AdSense — and may link to third-party websites. We do not control those parties, and their own terms and privacy policies apply to them. Advertising is currently disabled; when it is active you will see an “Advertisement” label above the ad units.

7.Changes

We may update these terms. When we do, the “last updated” date at the top of this page changes. Continuing to use the site after a change means you accept the new version.

Privacy Policy

What we process

The address you enter is used to perform the check. It is never written to a database.
To keep the “Recently checked” list fair and to enforce rate limits, the server holds in memory: the domain names of the last ten checks, and a salted one-way hash of the visitor. Never the IP address itself, and the salt is random for each run of the server.
The moment a check finishes, the full URL — including the path and any query string — is discarded. Only a domain name can appear in the list.
When something unexpected happens, the server writes an error message to its system log so we can fix it. Such an entry can contain the address involved in the check.
If you use the contact form, we process your name, your email address, the subject and your message in order to reply to you.

What we do not do

No accounts, no tracking pixels, no analytics, no advertising profiles of our own.
We do not download page content: we read the response headers and discard the body immediately.
We do not sell your data or share it with third parties.

How long we keep it

The “Recently checked” list lives only in memory and is gone the moment the server restarts — including after every deployment.
The system log is kept by the operating system on the server and rotated there, so it does not grow without bound.
A contact message stays in the recipient’s mailbox until it is no longer needed.

Legal basis and your rights (GDPR)

For visitors in the EU/EEA our legal basis is legitimate interest: keeping the service available and free of abuse by enforcing rate limits. When you send us a message, the basis is that we are answering a request you made. You can ask what we hold about you, ask for a correction or deletion, or object to processing — use the contact page. In practice the only thing that could identify you is a message you sent, or a domain name in an in-memory list that disappears at the next restart.

Cookies

We set no cookies ourselves. If advertising is enabled, Google and its partners may set cookies and process data; where the law requires it, we will ask for your consent before that happens.
