How did advertisers track me?

Summary of Request
Hi I have used the Facebook data download tool, but failed to find the information I was looking for. My understanding is that advertisers have many tools to construct audiences. I can see at least: - hashed email address - pixel information - page likes - apps i have interacted with - companies where i have logged in on their site through Facebook - companies where i left a comment using my Facebook account - companies whose website i visited, which has a social plugin - some (hashed?) device identifier (?) - ??? The Facebook download tool certainly has information that goes in this direction, but I fail to retrieve this distinction on the means of tracking in the output of that tool. It is my understanding that "which tracking method was used" is part of the personal data I am entitled to get access to under all the relevant legal instruments. Therefore, please provide me with all the information held by Facebook on the topic of which tool was used to track me with each advertiser.

Dear Mr << Name removed >> , Thank you for your email in relation to how to access your Facebook data. We can confirm that we provide users with this access in a number of ways, only one of which is via the Download Your Info tool which you refer to. In particular, most of a users' data is available simply via logging into their Facebook account or by accessing their Activity Log. These specially designed self-service tools for users to access their data have been reviewed by our data protection regulator, the Irish Data Protection Commissioner, as our means for providing you access to your information. Further information on how to access your Facebook data can be found here: https://www.facebook.com/help/4051835... This link also provides a table setting out what categories of Facebook data are available to users and where these can be found. The information you are looking for should be available in this table. However, if we can be of further assistance, please let us know. On a separate topic, we understand that you have forwarded your request to Truste. As we have explained to you previously, Facebook Ireland is the data controller of the personal data of Facebook users who reside outside of the United States of America and Canada. It is the entity responsible for queries relating to data subject access requests (not Facebook, Inc. or any other entity within the Facebook family of companies). Facebook Ireland is subject to the jurisdiction of the Irish Data Protection Commissioner, not TRUSTe. We are nonetheless going to forward on this response to TRUSTe for their information.

Dear Facebook, Either you have misunderstood my question, or you have answered another question more purposefully. In any case, this is not an answer to my question, which I invite you to reread. Meanwhile, whatever recourse mechanism I have decided to use will keep its course.

Dear Mr << Name removed >> , Thank you for your email. We are sorry if you feel our previous response did not fully answer your questions. We are sincerely trying to give you the information you are looking for. Should it assist, we can break down our response to you using the specific line items included in your initial query: - "hashed email address" Advertisers do not give Facebook any user contact details. We only get such details in hashed form and they are, in any event, deleted within 48 hours. We are therefore not able to confirm what contact information an advertiser has for a particular user, or whether that may include an email address. However, a list of advertisers that have your contact information (which may include your email address) is provided via our DYI tool and also in your Ads Preferences. - "pixel information" You can find a list of adverts you currently have the potential to see as a result of the use of Facebook pixels on websites you've visited in the "Advertisers whose website or app you've used" section of Ads Preferences (found under "Advertisers you've interacted with"). - "page likes" You can find information about the pages you have liked in your Activity Log (using the filters "Likes" > "Pages and Interests"). - "apps i have interacted with" You can find information about the apps you have interacted with in your Activity Log (using the filter "All Apps"). - "companies where i have logged in on their site through Facebook" You can see apps where you are logged in through Facebook here: https://www.facebook.com/settings?tab... You can also find further information in your Ads Preferences: see "Advertisers you've interacted with" > "Whose website or app you've used" - "companies where i left a comment using my Facebook account" You can also find this information in your Activity Log (using the filter "Comments"). - "companies whose website i visited, which has a social plugin" Advertisers are not able to construct audiences through social plugin impressions data. When a user interacts with a social plug-in, such as by liking a certain third party website, this information is made available to the user in their timeline, and can subsequently be accessed via their Activity Log. - "some (hashed?) device identifier (?)" You can find information about, and controls for, advertising device identifiers through your mobile operating system's settings Regarding the separate matter of your continued reference of requests to Truste, as we have explained to you previously, Facebook Ireland Limited is the data controller regarding your use of the Facebook Service. As a result it is the entity which is responsible for responding to questions such as this. Your query is not directed to issues regarding data transfers to Facebook, Inc.; nor is this a matter that Facebook, Inc. would be in a position to assist you with, given it is not the data controller for the Facebook Service outside of the United States and Canada. Therefore, this is not a case which has any connection to the CH/US Safe Harbor scheme; and, correspondingly, Truste. As we have also explained previously, should you have any continuing concerns about this matter, you are entitled to contact Facebook Ireland's regulator with exclusive jurisdiction over issues such as this: the Office of the Irish Data Protection Commissioner, Canal House, Station Road, Portarlington, Co. Laois, Ireland. We will forward this response to Truste, for their information.
