Here are the main points of my personal data policy as it stands today:
Never share my current location publicly. I’m going to be certain my habits do not share my current location in a public way. I’m also going to audit any app or service that attempts to use my location data to be certain it does not share my current location publicly.
Download and remove all of my data from services that I haven’t used in over a year. I’ve got quiet an online trail that I’ve blazed over the last several decades. While I’m nostalgic for many of these services, and I hate dead URLs, I think it is best if I remove any of that data if I’m no longer using the service.
Evaluate each app on my mobile devices that use location data and read their privacy policies. In other words, make a more informed decision about what apps I share my location data with.
Delete any app that I do not use on my mobile devices that could use location or audio data. Believe it or not, many of the small utility apps that exist for free (like, doing fun image editing) have tons of third-party ad network code in them. I have dozens of these but I rarely use them.
I really like your approach Colin. I must admit that I have become more mindful of late, however I have a lot of work to do in making some of my practices more rigid.
