# Request for data collection review form

**All questions are mandatory. You must receive review from a data steward peer on your responses to these questions before shipping new data collection.**

1) What questions will you answer with this data?

What version on Firefox is sending the data?

2) Why does Mozilla need to answer these questions?  Are there benefits for users? Do we need this information to address product or business requirements? Some example responses:

* Establish baselines or measure changes in product or platform quality or performance.

* Provide information essential for advancing a business objective such as supporting OKRs.

* Determine whether a product or platform change has an effect on user or browser behavior.

3) What alternative methods did you consider to answer these questions? Why were they not sufficient?

The Glean SDK does not currently send a meaningful value for the OS version, when using the Rust Language Bindings.

4) Can current instrumentation answer these questions?

No.

5) List all proposed measurements and indicate the category of data collection for each measurement, using the [Firefox data collection categories](https://wiki.mozilla.org/Firefox/Data_Collection) found on the Mozilla wiki.   

**Note that the data steward reviewing your request will characterize your data collection based on the highest (and most sensitive) category.**

<table>
  <tr>
    <td>Measurement Description</td>
    <td>Data Collection Category</td>

  </tr>
  <tr>

6) Please provide a link to the documentation for this data collection which describes the ultimate data set in a public, complete, and accurate way.

Documentation will be automatically generated by Glean from the metrics.yaml file.

9) If this data collection is default on, what is the opt-out mechanism for users?

The data collection preferences in Firefox.

10) Please provide a general description of how you will analyze this data.

By querying the reported Firefox version data to understand the distribution of OS versions running Firefox.

11) Where do you intend to share the results of your analysis?

Internally.

12) Is there a third-party tool (i.e. not Telemetry) that you are proposing to use for this data collection? If so:

This is going through using the Glean SDK, no third parties.

Removed.
