GDPR: the right to be forgotten



GDPR: the right to be forgotten
The EU’s General Data Protection Regulation (GDPR), effective May 25, 2018, regulates how businesses can collect and process the personal data of EU citizens. Any business—even one based outside the EU—that has EU users must be in compliance with the GDPR. The regulation affords EU citizens certain rights over their personal data, for example:
  • The right to access: upon request, the business must send the user a digital copy of their processed personal data
  • The right to be forgotten: the business must delete all the personal data they have on an EU citizen upon request
In accordance with article 17 of the GDPR, you must notify Adjust when a user has exercised their right to to be forgotten. You can inform Adjust of a user’s decision through a call to our GDPR API endpoint or using the Adjust SDK. 

Once Adjust has been notified: 
  • we will permanently delete all of the user’s historical personal data from our internal system;
  • we will no longer receive the user’s information from the Adjust SDK; and
  • the device’s data will no longer appear anywhere in the Adjust Dashboard.
Requirements for GDPR API integration, instructions for Adjust SDK configuration, and real-time callback setup can be found below.

Important note for testing: Please exercise extreme caution when testing the API endpoint or SDK method using a personal device ID. When Adjust is notified of a user’s request to be forgotten, the subsequent process is permanent and cannot be reversed. Adjust will never be able to reinstate the device’s data or receive requests from that device for any reason.

GDPR API requirements

To integrate with the Adjust GDPR API, you will need to configure your servers to send a set of mandatory parameters (listed below) to Adjust through an HTTP GET request to our designated endpoint URL found below.

429Too many requests; you have exceeded the request rate limit set to protect against abuse and will have to resend the request later

Adjust SDK requirements

To notify Adjust of a user’s request to be forgotten through the Adjust SDK, you will need to ensure that you have integrated the Android, iOS, or Windows Adjust SDK version 4.13 or later.

Your developer can configure the Adjust SDK to send us the required information by following the instructions in our GitHub READMEs: Android, iOS and Windows.

How to receive right-to-be-forgotten activity from Adjust

When Adjust receives a request to be forgotten, you can be notified via Adjust’s real-time callbacks and our Amazon S3 bucket integration

Enter a callback URL for the erased users (GDPR) real-time callback or include the erased users (GDPR) event type in your Amazon S3 bucket upload. If you want to receive right-to-be-forgotten information through your global callback, make sure you include the {activity_kind} placeholder, which will be filled with gdpr_forget_device when the callback is fired for a right-to-be-forgotten request.
