Status: RESOLVED FIXED

(Core :: MathML, task)

Description

[Frédéric Wang (:fredw)]

Discussion happens here but it is currently blocked on collecting statistics to determine how important they are: https://github.com/mathml-refresh/mathml/issues/29

So we can introduce a runtime flag / counter to help with that.

# Data Review Form 

1) Is there or will there be **documentation** that describes the schema for the ultimate data set in a public, complete, and accurate way? 

This will be documented in the [probe dictionary](https://telemetry.mozilla.org/probe-dictionary/).

2) Is there a control mechanism that allows the user to turn the data collection on and off? (Note, for data collection not needed for security purposes, Mozilla provides such a control mechanism) Provide details as to the control mechanism available.

Yes, users can toggled this off by disabling Telemetry in the Firefox Preferences.

3) If the request is for permanent data collection, is there someone who will monitor the data over time?

:fredw will monitor this data, however collection is only proposed for 6 months initially.

4) Using the **[category system of data types](https://wiki.mozilla.org/Firefox/Data_Collection)** on the Mozilla wiki, what collection type of data do the requested measurements fall under?

Category 1: Technical Data

5) Is the data collection request for default-on or default-off?

default-on

6) Does the instrumentation include the addition of **any *new* identifiers** (whether anonymous or otherwise; e.g., username, random IDs, etc.  See the appendix for more details)?

No.

7) Is the data collection covered by the existing Firefox privacy notice? **If unsure: escalate to legal if:**

Yes.

8) Does there need to be a check-in in the future to determine whether to renew the data?

No.

9) Does the data collection use a third-party collection tool? **If yes, escalate to legal.**

No.
