Your fitness band or smartwatch collects a lot of important data about you, & communicates it to your smartphone. At each step, personal data is potentially open to interception by third parties.

Some health insures provide various incentives for policy holders to buy & use fitness trackers. Rationale is that fit policy holders are healthier & so cost the health insurer less. Some insurers require evidence, from the fitness tracker, that the user is reaching targets. This can create an incentive for the user to tamper with data.
