Hi there
Strava is awesome - nothing to add to that.
However, I have certain security and privacy concerns with regards to the combination of location information (track) and the timing of said recorded track. The location information is an integral part of Strava and I feel that security and privacy concerns are appropriately addressed. I struggle with the time stamp of the activity though. Everybody who has access to my activity can see WHEN I move WHERE. Many people tend to do the favorite routes they do at similar times of the day (before work, lunch time, after work, etc.). It would be awesome to not just have a privacy filter around the start and end location of a run, but also around the start time. For example: no exact time stamp but only the date.
In short: remove the threat that runner X is passing by the dark corner of the park every evening at 8:42 pm.
Thank you. Happy to hear other voices on the topic.
