It is not a mobile app. You export your data from Google (thanks GDPR!), and filter out personally identifiable data points before submitting. We also let you know exactly who is about to use your donated data (we only allow academic researchers to have access), and give you advance notice so you can delete it if you don’t want your data to be used in a particular project.
We are MIT licensed and are figuring out how to make data donation safe via UX and engineering. We need all the help we can get - even if it’s just feedback. Feel reach out! Nessup@gmail.com
