HUFFINGTON POST - Sep 10 - The privacy and security of location-based apps has become a major concern for smartphone users around the globe. Grindr security glitch exposes gay users in regions that criminalize homosexuality. Any app that shows relative distance between members can be used to pinpoint the location. It is called "trilateration". When a user elects to hide his distance on SCRUFF, the app not only remove the information from his profile, but they also randomize his location on their servers. In addition, SCRUFF partnered with ILGA, a non-profit that publishes an annual report of gay and lesbian rights worldwide. Coming soon, when a user travels to a country included in the ILGA report and launches SCRUFF, he will see an alert informing him of the presence of local laws criminalizing homosexual activity.
