Would you participate in a survey that requires you to download an app that monitors your data?

I've been making money by using LifePoints and Panelbase, where you fill in surveys. Recently I've had 2/3 opportunities to make money where they ask you to download an app so they can monitor your data for a month or so.

During this cost of living crisis, I could really do with the money. However, everyone I've asked has advised I don't participate in these ones..

What do you think?
