Terms of use
These apply when you subscribe to security alerts for a domain. They are short and specific, because this is what you read before agreeing.
Who may subscribe. You confirm that you have authority over the domain you subscribed — you run it, work on it, or are the vendor responsible for it — and that you may receive mail about its security. Subscribing someone else's domain is something we may refuse, cancel, or report to the party concerned.
What we do. We fetch the home page and the files that page already sends every visitor, the way a browser does, to read software version numbers. At most once a day, at least a few seconds apart. We do not log in, try passwords, fuzz parameters or paths, attempt exploitation, or read anything beyond public content.
What we send. Exactly three kinds: (1) a confirmation of the subscription, (2) an alert when we find a critical vulnerability in software the site runs, (3) one reminder after 14 days if there is no reply. No advertising, no newsletter, no selling or renting the list.
What we keep. The email address, the domain, when it was subscribed and confirmed, which version of these terms was agreed, and a salted hash of the IP address (never the address itself). The only purpose is sending alerts and proving consent. Data is kept until you cancel, and deleted within 72 hours of cancellation or of your request.
What we do not do. We do not publish your domain as a site with a vulnerability. We do not share the address with third parties beyond the mail host (to send) and authorities where the law requires it.
No warranty. This is a passive check based on public versions. It is not a penetration test, and it can miss vulnerabilities behind a firewall, behind a CDN, or in the site's own code. There is no guarantee of completeness or timing.
Cost and continuity. The service is free. We may stop or change it, and will say so in advance in writing if that affects an active subscription.
Cancellation. Every message carries a cancellation link. Once cancelled, we send nothing more to that address.
Governing law. These terms follow Vietnamese law. If a part is unenforceable, the rest stands.
