This isn’t just a great option for Facebook, of course. While many messaging apps, including WhatsApp and Signal, strip (but don’t save) metadata, iMessage and email attachments retain embedded data, as do photos added to shared albums.

If you’re sharing photos, there are many reasons you might not want to share the exact location. Putting safety aside, many a person has been caught out by inadvertently revealing where they are (and where they are not) via this invisible metadata.

I have warned on this Facebook and Instagram loophole before, and when I have asked Facebook about this, it has confirmed that the platform “collects and processes” such data. When asked if this is used for advertising, “regardless of the privacy settings selected by a user,” I was told it was fine to proceed with those assumptions.

Facebook has enough of your data. This is a great example of where you can hold something back without any detrimental impact to you whatsoever. If you’ve taken the trouble to stop Facebook capturing your location, make sure it’s doing as it’s told.
