User counting
How eyeo protects privacy while counting users.
To improve eyeo's understanding of cross-platform usage and versioning, the eyeo Browser Ad-Filtering Solution collects some user data.
Because one of eyeo's driving principles is to respect user privacy, no requests sent to data collection services contain any personally identifiable information (PII).
This page contains information on how and why eyeo implements user counting in its ad-filtering solutions.
Why eyeo count users
eyeo count users who have both ad-filtering and Acceptable Ads scheme enabled, as well as those who only have ad-filtering enabled. eyeo does this for the following reasons:
Understanding user distribution across Chromium and Solution versions helps eyeo decide which versions to maintain and which to deprecate.
Understanding user distribution across operating systems and platforms helps eyeo prioritize quality assurance and automation efforts on the most popular platforms and OS versions.
Understanding how users perceive Acceptable Ads, which eyeo determines from user opt-out rate. eyeo wants to ensure that ads that users see don't negatively impact user experience.
Establishing the basis of payouts to partners who monetize their Acceptable Ads users.
How user counting works
A ping request is sent automatically by the Solution to eyeo's dedicated service at least twice per day, if the browser is in use (including in the background) and ad-filtering is enabled. These contain no personally identifiable information.
Ping request payload
To track active clients while maintaining user privacy, the server combines the values of ping timestamps with a randomly-generated tag. Dates are truncated to further protect privacy.
The following table outlines the parameters sent with the ping:
Parameter | Type | Description |
---|---|---|
| string | Number only used once, one of the algorithms that might be used to generate nonce is UUID4. This helps to anonymously distinguish between several ping requests with the same values for the rest of the parameters. |
| string | Identifier of the Solution. Example: |
| string | Version of the Solution, corresponding to |
| string | Name of the application. Used for attributing users to a specific product. Example: |
| string | Current version of the application. Often follows the underlying Chromium version. Example: |
| string | Timestamp of the first ping sent by the client and acknowledged by the server (as measured by the server), extracted from the first 2xx response body. Example: |
| string | Timestamp of the last ping sent by the client and acknowledged by the server (as measured by the server), extracted from 2xx response body. Example: |
| string | Number generated by the client using UUID4 when it receives a response with a |
| string | Timestamp of the previous to last ping sent by the client and acknowledged by the server (as measured by the server), copied from the last request. Example: |
| bool | Whether the client opted into Acceptable Ads. |
| string | Client operating system. Example: |
| string | Respective version corresponding to the OS. Example: |
