You cannot officially designate anything to be "off the record". That's just not a thing that the legal system recognises - the closest thing might be attorney-client privilege, and that's not relevant here, so none of your analysis applies.
> Let's assume technology-wise, there are indeed no records kept, everything is ephemeral. Should the court order then apply to those chats?
No, there is no record to be kept.
> Now assume that the programmer of the app made an error, and accidentally records are kept for 24 hours. Should the court order now apply to those records?
Yes, the court order applies indiscriminately to all records no matter why or how they were made.
> Now assume that the programmer of the app made an error, and accidentally DATA is kept for 24 hours. As part of the error, the DATA is also automatically deleted after 24 hours.
What now?
You want there to be some kind of big tricky debate to be had about what kind of data is or isn’t a record. There is none. People know what a record is and when they encounter one. If you are storing something for a time, you have a record of it. It really is that simple.
Maybe the world is just more complicated than you'd like to admit.
No, it’s not at all what I’m saying.
What I’m saying is that if you are keeping records of what’s said for a time like most chat apps do then these records are indeed records and no amount of hypothetical distorting regarding RAM or amount of time or what not will change the fact that they are records and you will have to keep them if the court tell you to do so.
If you were using a P2P messaging app where no storage was done at all at any point then you would have no record. It’s not that complicated honestly. Just don’t keep records if you don’t want there to be records.
But ... its not that simple any more.
A lot of the time, apps will be hibernated/suspended to disk, and then restored from disk. So talking about ram and storage in context of devices its kind of hard. Even some browsers now "suspend" your tabs to ssd, and then resume when you click back to them. So it's kind of hard to say if something was never on the disk or not.
I guess you could go with intent, that either app intentionally stored something or not, but then again you also design apps with suspend in mind so not sure how this one would play out.
There's a massive difference in deleting records that did exists vs. records that never existed in the first place.
The former is deleting data, the second case isn't.
Let's give you a concrete exemple we have had rulings on without any computer involved, which are almost a 1:1 situation: you are on litigation hold, and aren't allowed to destroy any records. You do an oral meeting, with no plans to put it on paper.
Unknown to you, someone took notes during the meeting, say your secretary because she didn't feel well that day and wanted to be sure to remember it the next day.
Although those notes were not planned to exist, once they do destroying them is destroying records, and you're in violation of the litigation hold.
You may not notice her take note, and then see her pull the notes our of her bag the next day and at that point it's illegal for you to ask her to destroy them.
There is the whole situation of people asking to switch to the no history mode, but that's not retroactively applied and it's really no different than sending an email that says "let's talk about this over the phone".
The real open question is whether Chats can have a temporary nature to them as they are inherently a written record. But there's also other situations where you can have a written record, for example, if someone uses auto-captions on a video call. They're very short-lived, but they did exist for some duration.
I am not sure why you are making this distinction when it doesn't exists.
Litigation hold also means stop all software automation that would result in destruction of record, doesn't matter how many people know about it. Case in point: that is what happens to their 30 days old chat. This is the same thing if you trigger a litigation hold on your office365 account or whatever.
And for the rest of your point: not only does the law not accept the "oh but I didn't know", for the obvious reason that then it's an easy out, but even if they did tolerate extreme exemple of it Google cannot in good faith claim lack of knowledge about THEIR OWN system, the litigation hold was not for those specific people who may or may not know it, it was for the company who is then in charge of ensuring their IT team does what the court ordered.
The real debate is about whether "off the record" text can exist at all, and if so, under what conditions/duration? Are captions on a video call a text record? Do those need to be retained?
> The real debate is about whether "off the record" text can exist at all, and if so, under what conditions/duration
This question makes no sense, as you what you are asking is "can i not make a record, when i make a record of something to transmit it to someone else"
> Are captions on a video call a text record? Do those need to be retained?
Yes and yes, of course. It's legally a record. Again, this questions makes very little sense legally.
