Fitness apps that track data such as geolocation information can put users at risk of malicious actors accessing that information and using it for criminal or other unsavory purposes.
To stay safe, users should exercise caution when choosing, using and selecting the privacy setting on fitness apps.
First, users should carefully read through each app's privacy policy to learn what data is collected, for what purposes, what rights users have regarding their personal data, and what data might be shared with third parties.
It's also recommended to install at few different apps as possible as keeping fewer apps decreases the risk of data leaks.
Additionally, users should restrict which data fitness apps access, with the ultimate goal of limiting that access to only the data required for the app to work.
Users should also check to whom fitness apps share data and consider if the app is sharing data with individuals or parties they do not know.
Finally, users should routinely check their smartphone privacy and security settings to ensure apps do not have unnecessarily open access to their data.
It is important to note that privacy settings will not protect users if someone accesses their account with their password, as most popular running apps currently do not support two-factor authentication.
Some popular running apps that have specific guidelines about setting up privacy and protection are Strava, Nike Run Club, MapMyRun, adidas Running (formerly Runtastic), and ASICS Runkeeper.
