What is Ghostery?

Ghostery is a browser tool available for Firefox, Chrome, Safari, Opera and Internet Explorer. It scans the page for scripts, pixels, and other elements and notifies the user of the companies whose code is present on the page. These page elements aren't otherwise visible to the user, and often not detailed in the page source code. Ghostery allows users to learn more about these companies and their practices, and block the page elements from loading if the user chooses.

Will Ghostery affect my browser performance?

Ghostery initiates a scan and decision for several types of page elements, and in some cases, this scan may represent a slight increase in page load times. However, if users choose to block page scripts, our lab research suggests that pages load faster on average.

Ghostery is owned by Evidon, Inc. What is Evidon?

Evidon is a new type of company that brings trust to online advertising by working as an intermediary between consumers, advertisers, industry self-regulatory programs, and government. Evidon helps consumers protect their privacy and keep quality content ad-supported and free. Neither Evidon nor any third party on their behalf is involved in the collection or sale of any data, behavioral or otherwise, for use in ad targeting. Evidon is not an advertising network or behavioral data collection service.

Evidon provides technology that allows the online advertising industry to be more transparent in how they collect and use consumer data. In turn, they give consumers more control over their privacy online. We strongly believe that making disclosure more transparent will raise the quality of the entire online advertising industry by enabling advertisers to grow and innovate.

We realize that this is an ambitious mission. There's going to be an acclimation period as people discover our service in the market and come to understand what we represent. We are a group of individuals from the privacy and technology fields, who believe very strongly that while advertising is here to stay - it powers the vast network of free information consumers rely on - it should not come at the price of an individual's right to privacy.

Ghostery is a free plug in. Is that going to change?

Ghostery will remain a free, non-commerical service. There are no plans to create a version of Ghostery that requires user payment.

How will Evidon's acquisition of Ghostery benefit Ghostery users?

With the help of the Ghostery community, we can create the web's most capable and comprehensive user privacy tool.

Is my data safe? What is Evidon going to do with it?

Ghostery users are anonymous. If you elect to download the Ghostery plug in, you'll note there are no registrations or sign ups required. The Ghostery plug-in does not place session cookies into your browser. Neither the Ghostery application nor Evidon receives any data from Ghostery users unless the user opts-in to participate in GhostRank. In that case, data is collected in aggregate form and without any personal information, for research and industry monitoring purposes (more on GhostRank below). GhostRank data is never used for advertising targeting purposes. GhostRank is a true opt-in feature - all the other features of Ghostery are fully available whether or not GhostRank is enabled.

Ghostery's dedication to user privacy is capture in the Ghostery Browser Tool Privacy Policy.

What data does Evidon receive from users who opt-in to GhostRank?

When a user opts-in to GhostRank, we have access to the following information:

• Bugs identified by Ghostery
• Bugs blocked by Ghostery
• Number of times the bug has been identified
• Domains identified as serving bugs
• Advertisements served at particular domains, including companies associated with each ad
• Information about the type of notice associated with each ad
• The browser in which Ghostery has been installed
• Ghostery version information

What does Evidon do with GhostRank information?

GhostRank data will never be used target advertising. Evidon uses the data from GhostRank to discover new trackers on the internet, view specific performance and use statistics, and follow industry compliance with privacy and choice standards for behavioral advertising. The data also helps us understand where advertisements are served, who is associated with these ads, and whether these ads are compliant with industry self-regulatory programs. We may also use GhostRank data (on an aggregate and anonymous basis) to help us understand how advertisers and their vendors are honoring opt-out requests.

What other services does Evidon provide?

Evidon is something totally new to the online world -- a privacy assurance platform. We put tools for transparency and data use control directly in the hands of consumers, advertisers and the companies who provide the technology to get ads to consumers (advertising agencies, advertising networks, advertising exchanges and publishers). Our focus is to make the interactive advertising industry more transparent and to enable consumers to make informed judgments about the use of their data.

In addition to supporting Ghostery as a consumer service, Evidon provides services to the online advertising industry. Evidon's technology will power industry self-regulatory programs. We provide online advertisers and their partners (advertising agencies, networks, exchanges and publishers) with services to simplify their compliance with the Federal Trade Commission's Principles for Online Behavioral Advertising and the Cross-Industry Coalition's Self-Regulatory Program for Online Behavioral Advertising. The Evidon platform is built from the ground up with privacy in mind. It provides advertisers tools to disclose to users what information they're collecting and tracking. Furthermore, the platform helps advertisers give consumers the ability to opt out.

The Evidon platform is currently in beta launch across the web.
