1434445 - MMA: User attribute - Total number of devices registered under Fx Account

Status: NEW

(Firefox for iOS :: General, enhancement, P4)

Description

[Jean Collings]

To improve our contextual hints for FxA, we need to get a little bit granular with understanding where are users are in the FxA sign up/in flow. 

Ask 1: We would like to track total # of devices registered under a user's FxA

This would allow us to send specific messages to users with only 1 device in this flow to sync their account with other devices. 

Ask 2: We would also need to drop an event that indicates that they've actually synced or added another device - so we can measure the success of this campaign.

The code looks good to me. 

This looks like it needs to go for Data Review. https://github.com/mozilla/data-review/blob/master/request.md

Thanks James, let me know if I need to tag Chenxia in this bug. Here are the responses:


What questions will you answer with this data?

This data will allow us to know which users have not synced their devices and send tailored messages to these users to encourage them to do so.

Why does Mozilla need to answer these questions? Are there benefits for users? Do we need this information to address product or business requirements?

We know that users who have a FxAccount and sync across multiple devices retain longer on the browser. And the user will benefit the full Sync services (passwords, bookmarks, Send Tab) only if they sync across multiple devices.


What alternative methods did you consider to answer these questions? Why were they not sufficient?
The alternative method is to not have this as an user attribute but without it, it would be difficult for us to understand if users are synced or not, therefore the ability to send tailored messages to encourage them to move to the next step in the Sync flow.

Can current instrumentation answer these questions?
Having this as an user attribute will help answer our question

List all proposed measurements and indicate the category of data collection for each measurement, using the Firefox data collection categories on the found on the Mozilla wiki.

Measurement Description     Data Collection Category     Tracking Bug #
Track total # of devices registered under a user's FxA 

This would allow us to send specific messages to users with only 1 device in this flow to sync their account with other devices. 

I think this is a Category 2.

2) We would also need to drop an event that indicates that they've actually synced or added another device - so we can measure the success of this campaign.

Also category 2.
     
I want this data to be collected for 6 months initially (potentially renewable).

What populations will you measure?
Firefox iOS release / FxA users
    
Which release channels?
Current release channel and future release channels

Which countries?
The countries/locales that Leanplum is currently connected to:

en_US, en_GB, en_CA, en_AU, en_HK, en_SG
de_DE
fr_FR
zh_TW
it_IT
id_ID
pt_BR
es_ES
es_MX
pl_PL
ru_RU


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

Please provide a general description of how you will analyze this data.
Take FxA users who have only 1 device and see if they have taken an action from our message to sync to 1 or more devices

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

This info is also already in the Sync Ping. For reference https://firefox-source-docs.mozilla.org/toolkit/components/telemetry/telemetry/data/sync-ping.html#syncs-devices
