If the user modifies/accesses the same item on multiple desktop profiles, it could be possible to link them, but an event involving that item has to be generated on each client first. One of the product questions we care most about is cross-device (mostly mobile + desktop) access of the same credentials. Note that the mobile lockwise apps are stand-alone and have unique client_ids (i.e. are not the same as firefox android/ firefox ios). For the mobile apps, I believe we have legal approval to to do this sort of cross-device analysis. Sandy can you confirm this, I think it was michael feldman? However I get that we are in desktop realm now so things may be different. > Is this part of the collection required in order to answer the data collection review's questions? Could we instead use a different (perhaps client-local) id for the items? See above, yes product management cares very much about cross-device access. Sorry Chris, I could have been more explicit about this to begin with.
