# Request for data collection review form 1) What questions will you answer with this data? To support top-line 2019 KPIs we will need to measure Telemetry about our products (Firefox, Fennec, Lockbox, …) from the point-of-view of our cross-product product Firefox Accounts. This will include questions like: * When someone creates a firefox account for sync, does their general browsing behavior change? * When someone connects a new app to their existing account, how do their overall usage patterns change? * When someone connects another device to their account, how does retention change on all of their devices? 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: To enable cross-product analysis of key engagement data from before and after a user logs in to Firefox Accounts. 3) What alternative methods did you consider to answer these questions? Why were they not sufficient? We currently don't have other methods to answer these questions across products. 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) 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.**
