TECH CRUNCH - May 15 - Tinder is developing a feature that tracks users location via its app, then shows potential matches where they've been. The idea is to allow people to come across their real-life missed connections, similar to how the dating app Happn works today. This feature will be opt-in. The way Tinder has implemented the location feature is concerning. Instead of allowing users to explicitly "check in" to a given place – like their favorite coffee shop or a cool restaurant or bar – Tinder continuously tracks users' location with its app, then makes a determination about which of their "places" it will show to potential matches. The company, at least, thought to remove things like doctors, dentists, banks, and the place where people live or work from this automated location-sharing option. It also won't add a place to the list until after they've left – though it doesn't say how long it waits to do so.
