General notes regarding privacy, our site and Third-Parties

This website uses Google Analytics, a web analytics service provided by Google, Inc. ("Google"). Google Analytics uses "cookies", which are text files placed on your computer, to help the website analyze how users use the site. The information generated by the cookie about your use of the website (including your IP address) will be transmitted to and stored by Google on servers in the United States. Google will use this information for the purpose of evaluating your use of the website, compiling reports on website activity for website operators and providing other services relating to website activity and internet usage. Google may also transfer this information to third parties where required to do so by law, or where such third parties process the information on Google's behalf. Google will not associate your IP address with any other data held by Google. You may refuse the use of cookies by selecting the appropriate settings on your browser, however please note that if you do this you may not be able to use the full functionality of this website. By using this website, you consent to the processing of data about you by Google in the manner and for the purposes set out above.

We implement some Google Analytics features including remarketing (to advertise online), Google Display Network Impression Reporting, the DoubleClick Campaign Manager integration, and/or Google Analytics Demographics and Interest Reporting. Users can opt-out of Google Analytics for Display Advertising and customize Google Display Network ads using the Ads Settings. WhatIsMyBrowser.com and third-party vendors, including Google, use first-party cookies (such as the Google Analytics cookie) and third-party cookies (such as the DoubleClick cookie) together to inform, optimize, and serve ads based on someone’s past visits to the Site.

The data and insights gathered from Google Analytics Demographics and Interest Reporting is used to optimize the ads and types of ads used on this site, as well has how the site is designed and marketed. We do not facilitate the merging of personally-identifiable information with non-personally identifiable information previously collected from Display Advertising features that is based on the DoubleClick cookie unless you have robust notice of, and your prior affirmative (i.e., opt-in) consent to, that merger.

Notes regarding Privacy and our own systems

When you access this site, this site may record the user agent, headers, detected addons, IP address and other data. This is done either as a part of the requirements of the functionality (eg the Unique Browser Url feature needs to record details of your setup, so that it can re-display them when the unique url is visited), or as a part of the maintenance, development and monitoring of the site.

Any time you provide your name, email (or the name, ticket number and email of your tech support), we will record it for monitoring, security and development purposes but promise to never sell, give, loan, rent or otherwise provide it to any companies.

Terms and Conditions regarding particular functionality on the site

User Agent Parsing

Our user agent parsing software - used on the homepage, the iframe page, the custom parser page, unique browser code page, API and other places - is provided "AS IS", with no guarantee that it is correct or complete. It is our best attempt at decoding the user agents provided to it.

Like all functionality and content on this site; it is hoped that it is helpful, but no guarantees at all are given and it should be used simply as a guide.

The information provided by it (and thus in all the places on the site - homepage, API, custom parser etc) is subject to change without warning or notice to you or anyone.

It is custom software we have written ourselves over the course of many years. If you want to integrate your software with it; please consider using our API.

Collection and further development

The user agent parsing software we use on the site and in the API is developed in-house, we do not simply repackage an existing library - we build it ourselves. In order to develop it further, we will collect and store any user agents we receive either on the website or via the API (including extra information such as HTTP Headers). These user agents are then prioritised and used to further develop the user agent parser.

If you do not want us to collect and store a user agent or HTTP header, do not transmit it to the site.

Don't scrape the detection

You are not allowed to "scrape" detection results from WhatIsMyBrowser.com. In other words, you can't write software to send HTTP requests with the User Agent you want to detect and then scrape the resulting page that WhatIsMyBrowser.com returns - on either the homepage, the user agent parsing page, the iFrame or any other page. We have an API which will give you far easier and more powerful access to this information. Use that instead. By using the API, you'll also be helping by supporting the project.

When our systems detect you scraping our site, you will be blocked from accessing the website.

Version checking and security

One of the features provided by WhatIsMyBrowser.com and the WhatIsMyBrowser.com API is the ability to get an indication if a web browser or some plug ins (Adobe's Flash and Oracle's Java) appear up to date. By using this site, you understand and agree that these are rough indications, not any sort of guarantee that your software is actually up to date. Is is provided as a helpful feature, but guarantees nothing, including whether or not this information is actually correct at all.

Due to the nature of the system, there will be a lag in time between a new version of a software package being released and our version checking data being updated accordingly. During this time our software would report that the browser or plugin appeared up to date when technically it was no longer up to date. By using this website you accept this and will not hold us liable for any confusion, security problems or any other problems or issues which may arise from these facts.

In some cases, the browser version check (checking if the user's browser is up to date) only looks at the major release version number, not the minute point release, and as such may not give an "out of date" for minor point or revision release differences. This is particularly true of Firefox which now only accurately reports the "main" version number and will in-fact give the wrong "point release" number (eg reporting "50.0" when it's actually "50.1". As such, for Firefox we can only check the "main" version number and warn if it is out of date.

In some cases, it is not possible to determine if a browser is fully patched, despite appearing up to date. In some cases (for example Internet Explorer), when a new version is released but the older version is still most popular and still actively maintained by the vendor, this may be considered the "latest" version. Browser security and remaining up to date is the responsibility of the Manufacturer and the individual computer user. We absolutely will not accept any responsibility for wrong, erroneous, misleading or vague information that this feature provides or the resulting decisions by the user thereof.

Just because the messaging on this website or the API may claim that your web browser (or your customer/client's web browser) is up to date does not guarantee that it is actually up to date, fully patched, or that it is secure. This feature should be used as a rough guide only. It is not any sort of guide, guarantee, promise (or otherwise) that your web browser is up to date or that you are using the internet safely or securely.

IFrame feature

You can only embed the WhatIsMyBrowser.com iFrame feature on your site provided that:

  • You agree that all the standard Terms and Conditions of using WhatIsMyBrowser.com (which you are now reading) apply to using the Iframe.
  • You will not intentionally obscure the link back to WhatIsMyBrowser.com in the bottom of the iframe, and thus:
  • It remains clear to all your users that the web browser detection is being done by WhatIsMyBrowser.com and they can click back to this site if they want.
  • You understand that this is a new feature of the site which is still in development. The way that it works, including its configuration options and output may change without notice as other websites start to use it and I modify and improve its behaviour.

Custom User Agent Parser

We provide a system which allows you to insert any user agent you want us to parse and receive our parse result for it.

The same user agent parser which we built, that powers the website and the API is used for this.

We log access to this tool and we may decide (at our discretion) to rate-limit or block abusive access to it, at any time, without warning or notice to you. Please do not abuse the system.

Send to Developer email feature

One of the features on this site is the ability to email a browser detection report to your tech support or your web developer. While the Privacy & Cookies section above hopefully explains our policy on privacy (namely that we are very supportive of your right to be anonymous, private, spam-free and safe on the internet) since the Send to Developer feature specifically asks you for two email addresses, it's worth taking a second to be perfectly clear about it.

We will never use your details for nefarious purposes. We will never send the email addresses spam or anything else other than the one email that using that system initiates. We will not give, sell or otherwise make available your details to any third party so that they can spam you either.

When you use the Send to Developer email feature, the contents of the email that is sent, including the name, to and from fields are stored in our database. However this is only done to prevent abuse and to ensure that the system is working.

Be aware though; we use Postmark to send these emails; so their systems will necessarily receive a copy of this data as their systems send the email.

By agreeing to use this site and this feature, you accept and acknowledge that all email is a fundamentally insecure transmission medium. You should not consider email to be private or secure at all.

Tor Exit Node Detection

The detection which tries to determine if you are coming from within the Tor Network/From a Tor Exit Node is provided without any guarantee of its correctness, or of your privacy, anonymity, untraceability, or anything else like that. Use it only as a rough guide and make sure you know what you're doing before you use Tor.

Minimum System Requirements feature

We provide a system which allows you to link to a service on our website which helps your users determine if their system meets your minimum requirements for using your website.

This system (like everything on this website) is intended as a rough guide only. It/We provide absolutely no guarantee that if it decides that your user's system should be able to use your website (eg that it meets the minimum requirements you have detailed) that it actually can or will be able to use your website (or that it won't).

When you provide us your logo to include on your custom-branded page, you assert that you own the right to use the logo and we all agree that obviously it remains your property, not ours.

If you use the IFrame embed option, you will not intentionally obscure the link back to WhatIsMyBrowser.com in the bottom of the IFrame, and thus, it remains clear to all your users that the web browser detection is being done by WhatIsMyBrowser.com and they can click back to this site if they want.

Unique Browser Codes

Every time the homepage of whatismybrowser.com is loaded, a unique "browser code" is generated for that page request. It stores the IP address, user agent and other information contained in the HTTP request. If Javascript is enabled in your browser, it will also record a list of your detected frontend capabilities.

This is done so that you can be provided with a unique url which describes your browsing set up at the time that you requested the homepage. This unique url is shown near the top of the page; just under the larger blue section of the page.

Each of these unique URLs will show anyone who views it a copy of the browser report associated with it; including the browser, user agent, frontend capabilities and other various bits of information. Only the first two octets of the IP Address are shown, to increase privacy (as some people share their urls on Twitter or other public forums).

If you do not wish for your browser report to be shared with anyone, do not give them your unique url.

Contacting us

We provide a contact form, allowing customers/users of the site to contact us with questions, commments and feedback.

We ask for your name and email so that we can reply to you if appropriate. We will never spam these email addresses or sell/give them to anyone who will.

When you use this feature, we record your browser's user agent, frontend capabilities (similar to what gets shown on the homepage/send in the email tool etc), HTTP headers and ip address so that we can better respond to your enquiry and help prevent abuse of the system.

When you send us a message, a copy of it is kept in our database and a copy is sent through to our main email address so that we are aware of your message to us. Please understand that email is an inherently insecure communication medium; do not send us sensitive information via this form/email. We provide our GPG key if you wish to send us encrypted email: WhatIsMyBrowser-info.asc.


If you do not agree to any or all of the above terms, you may not use whatismybrowser.com.
