Apps storing/selling personal data?

For those of you who use apps for self-tracking, do you feel like your data is secure? How do you feel about them storing and possibly sharing your personal data with third parties?

Hi Emma,

Among the many kinds of insecurity self-tracking apps expose their users to, among the worst, in my opinion, is data loss. Any long term self-research project that does not involve a personal copy of the record of observations is very likely to confront the disappointment of losing data.

I don’t mind provided I can make the informed decision to share my data or not.

Scary to thing the major hack that Garmin had last year!
