The CEO of fitness tracking app Strava has responded to security concerns raised this week regarding the publicly-available details of secret military bases. In a blog post, James Quarles addressed the sensitive nature of information readily available on the app's heatmap feature and said the team is "taking the matter seriously". Strava is "committed to working with military and government officials" to address the issue, he said, adding that the team is reviewing features that were originally designed for "athlete motivation and inspiration" to make sure they can't be used nefariously.
