Status: RESOLVED FIXED

(Firefox for Android Graveyard :: Web Apps (PWAs), enhancement)

Description

[Petru-Mugurel Lingurar [:petru]]

Currently, regarding PWAs we only track user actions in regards to the dialog for adding a PWA [1].

This ticket is for adding telemetry tracking for "launching web apps from the Home Screen".

Request for data collection review


1) What questions will you answer with this data?
When the user opens a previously saved Progressive Web Application from the homescreen.

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? 
Provide Product with insights about usages of the Progressive Web Application.
    
3) What alternative methods did you consider to answer these questions? Why were they not sufficient?
The proposed implementation is the only way to get the needed info.

4) Can current instrumentation answer these questions?
There already exists telemetry for some events regarding PWAs but none that would offer this newly needed data.

5) List all proposed measurements and indicate the category of data collection for each measurement, using the Firefox data collection categories on the Mozilla wiki.
 - Measurement Description: We only need to know when a PWA is launched from the homescreen<br />
 - Data Collection Category: Category 2 “Interaction data”  	
 - Tracking Bug #1490670
		
6) How long will this data be collected?
I want to permanently monitor this data. (Andreas Bovens)

7) What populations will you measure?
Firefox for Android users which have added a PWA to the homescreen and have telemetry enabled.
 - Which release channels?: All
 - Which countries?: All
 - Which locales?: All

8) If this data collection is default on, what is the opt-out mechanism for users?
Data collection is by default on for Nightly and Beta users and by default off (Telemetry is by default disabled) for the Release applications.
Users can opt-out by turning off telemetry from Settings -> Privacy.

9) Please provide a general description of how you will analyze this data.
Data will be used to better understand the usage of Progressive Web Applications.

10) Where do you intend to share the results of your analysis?
Data will be available only to specific persons within Mozilla.

:petru, can you also update the telemetry docs with this? Please update this file in-tree: https://searchfox.org/mozilla-central/source/mobile/android/docs/uitelemetry.rst and then flag me for re-review.

Thank you, :petru!

1) Is there or will there be **documentation** that describes the schema for the ultimate data set available publicly, complete and accurate?

Yes, added in uitelemetry.rst

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, Firefox for Android telemetry controls

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

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?  **
Type 2, user interaction

5) Is the data collection request for default-on or default-off?
Default off for release, on for beta/nightly

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? (Yes/No) (If yes, set a todo reminder or file a bug if appropriate)**
No, collecting basic usage information for a feature
