jwang changed the visibility from "Public (No Login Required)" to "All Users".

@jwang: Hi, was this view policy change intentional? Asking as it makes no sense, given our setup that anyone can create an account anyway. :)

Approved by Legal.

@APalmer_WMF , Thanks.

To make it more clear, I added the description of the kept columns in the proposal.

@JFishback_WMF, please let me know if you have any concern.

Hello @jwang thanks for reaching out. Is the purpose just to track usage long-term? Also, if you don't need high-precision time, I would remove dt from the schema as well. It looks like you can still track hourly precision without that field? Other than that, this looks fine to me.

For future reference if you'd like to request a privacy review from Security you can use this process (specifically step 2). That form helps to give me background on the ask. As a bonus, I run these reviews by WMF-Legal as well, so it's like a 2-for-1 deal! (Although I see you already reached out to @APalmer_WMF on this task.)

@JFishback_WMF, thanks for the review and suggestions. Right, when I started the review conversation, the process is unclear to me. Will follow your suggestion next time.

As for dt, it will be kept by default when we add schema to whitelist. And it's easier to extract date data with such data format. Let me know if you have further concern regarding it. If yes, I need to discuss with analytics team about how to opt it out technically.

Pending final review from @JFishback_WMF

Generally, the best practice is to minimize the data that is collected - especially high resolution data. That said, this data appears to be LOW risk, and per @jwang there is a countervailing interest in collecting the high resolution data in order to retain sequencing and other analytical uses.
