Who we are
- Netcraft owned websites (“sites”);
- Netcraft’s Report service (report.netcraft.com);
- Netcraft’s apps and extensions for browsers/mobiles and mail clients (“apps”).
If you have any queries or requests concerning your personal information, please contact us at email@example.com.
What information about you do we collect?
When you complete a contact form on our sites, you may provide the following information:
- Email address;
- Contact telephone number;
- Company name.
Your name and email address may also be shared with us when you install the apps through a store such as Google Play or Microsoft AppSource.
During use of the apps for browser/Android we will collect the following information from you:
- The website hostnames (not full URLs) you visit whilst browsing the web with protection enabled. These are used to identify malicious URLs (e.g. /fake-bank-login.html) that should be blocked within the hostname being visited. We do not collect details of the URLs that you are visiting, as these are only checked locally on your device. For example, if you visit “www.example.com/page/home", we will collect “www.example.com”. For the Android app, a list of supported apps installed on your device can be found under “Your supported apps” in the app’s settings;
- Some versions of the apps provide an SMS protection feature. These versions can be identified by a “SMS Protection” checklist item in the app’s home screen. These versions of the app collect hostnames (e.g. www.netcraft.com) contained within incoming SMS messages that you receive while the “Scan SMS messages” option is enabled. These are used to identify malicious URLs (e.g. /fake-bank-login.html) within the SMS message. These URLs are only checked locally on your device. If we detect a malicious URL within an SMS, then we will also collect the timestamp, caller-id of the sender, cryptographic hash of the message body (the message itself is not readable), and a list of the phishing URLs found.
Malicious Site Reports
When reporting a malicious site through the apps or on report.netcraft.com, the following information is provided to us:
- The URL of the site to report as malicious. These URLs may be visited by an automated process to check for malicious content and in some scenarios may visit sites that contain personal information. For instance the URL may contain your email address;
- If you opt to provide an email address, we will store it on your device. Whenever you submit a malicious URL via the app, this email address will be included in the report so that you can track your submissions.
Malicious Email Reports
When reporting a malicious email through the mail extensions or by forwarding to firstname.lastname@example.org, the following information is sent to us:
- Email address of the sender;
- Message content;
- Email address of the recipient(s).
Our sites use Google Analytics and Facebook Pixel to monitor the activity of users, so that we can make improvements to provide a better user experience. This information is not personally identifiable.
You can opt out of these analytics at any time by clicking the buttons below:
Analytics information is provided to us when an attempt to visit a URL is blocked by the Netcraft Browser Extension in versions 1.16.0 onwards. This is collected to improve the quality of the feed and aid in the identification of false positives. The following information is sent to us:
- The URL that was blocked
- The reason the site was blocked
- The version of the extension that you are using
- Country that the page was visited
- Information about your device, such as operating system and browser
We do not collect personal information which can identify the browsing habits of individual users. You can opt out by disabling “Allow analytics” in the options page of the extension.
Our sites use Facebook and Google analytics to generate audience lists for re-marketing adverts. This means that after visiting our site you might see our adverts on other sites in Facebook’s audience network or Google’s content network.
By opting out of analytics above you can exclude yourself from being added to our audience lists in future. You can also configure your Google or Facebook settings to prevent these adverts:

Why have we collected information?
Under the General Data Protection Regulation (GDPR), the lawful bases we rely on for processing this information are:
Some data collected is required by us to provide the service which you have requested, such as:
- Using a website hostname to detect whether malicious content is being hosted there;
- Responding to a query/request which you have submitted;
- Notifying you via email when new articles are posted on the mailing list;
- Providing you with information about a site.
We may share data with, if required, government bodies and law enforcement agencies.
We process some data for particular legitimate business purposes, such as:
- Monitoring how our services are used through logs, in order to determine their effectiveness and make improvements where necessary;
- Troubleshooting issues with and maintaining security of our services by using webserver logs;
- Aggregating hostname data from users of our apps in order to determine the busiest websites and other statistics, as well as using them as candidates for inclusion in our monthly Web Server Survey;
- Notifying you via email when the status of a malicious site submission has been updated. If you do not want to receive these updates, we provide an unsubscribe link in every email sent to you concerning your reports, which can be used to stop any further email updates regarding any and all of your reports.
How will we use your information?
Your data is used to allow us to provide our services. On occasion, we may share malicious mails that you forward to us with our customers, if the malicious content in the mail pertains to that customer. Otherwise, your personal data will never be shared with any third parties except successors in title to our business and, if required, government bodies and law enforcement agencies. We may aggregate data from our users to produce reports that may be shared; this data is anonymised and cannot be associated with specific users.
