An important omission is the data that Facebook collected on you using browser fingerprinting. Since a fingerprint is like a hash, it is theoretically impossible for Facebook to determine if the data really belongs to you, or to someone else who happened to have the same browser fingerprint. This means that if Facebook is legally obliged to offer a complete user data download, then the practice of fingerprinting is i…

That assumes that they collect such finger prints

One thing is clear. If they delete my data upon my request, they do not,for obvious reasons, delete it's contribution to any ML that was trained with it. Also, when deleting data, I wonder whether they delete any derived scores based on my data.

This is a very good point and one that I've been wondering but not seen much discussion of.

Yes. I'm waiting to delete my account until after the 25th because: * There's slightly more of a chance they'll actually delete my data * If they don't, I'll be entitled to be a part of any class-action.

Same, and I'll be encouraging others to do so.

What timezone are we using for this? Is it midnight Zulu on the 25th, the 26th?

Not covered here: it does not really export your social graph. Just a list of names. No way to easily import that into contacts etc. This is making quitting Facebook time-consuming, but I'm getting there. Similarly with birthdays, although it's quite easy to work around that via their calendar link.

Also, IIRC, all the photos are resized smaller and recompressed, while the full-res versions are still accessible through the Facebook website. This also makes it harder to quit if 1) you don't have the original photos and 2) don't want to live with the unnecessary sacrifice of quality.

Facebook really ought to include the best versions it has of the data you've uploaded, even if it makes the archive size enormous. The option to shrink things should be a non-default option only, since the download might be a prelude to an irreversible account deletion.

Will that be a possibility for people who are not from USA?

I had deleted (not deactivated) my account ~4 months ago and they were supposed to delete everything after 14 days but I have a feeling they didn't.

What do you mean not from USA? The legislation going into action May 25 is GDPR which applies to those in EU
