Does dq mean dequeue? Ironically, Grammarly would automatically expand your in-house abbreviations to make your writing more clear.
I’m sure the subject of a confidential investigation that could result in losing custody of their children would appreciate that Grammarly simplified that jargon in some attorney’s report. No problem at all that it’s stored in the cloud somewhere, monetized, or reviewed by some contractor somewhere.
I thought it meant "Dairy Queen[0]." Yummy[1], yummy Dairy Queen!
Using shortened/abbreviated forms without explanation is a recipe for misunderstanding.
Generally, writing out whatever will be abbreviated/shortened and noting the abbreviation/shortening is preferred, as it removes the ambiguity of just using an abbreviation.
For example, If I say that I'm going to "The Met," that could mean I'm going to the Metropolitan Museum of Art[2], the Metropolitan Opera[3] or The Metropolitan Police[4]. Which institution is implied may be clear from the context, but could be confusing.
Many years ago, I shared a taxi with a couple on my way to work at American Express. When I said I was going to "Amex," they assumed I was going to the American Stock Exchange and since their offices were quite close to that organization's offices, we decided to travel together.
Fortunately, the offices of American Express and the American Stock Exchange were both in the World Financial Center[5] (albeit at opposite ends), there wasn't an issue.
That said, clearly identifying shortened forms is extremely important, especially in writing, as you can't correct a reader's assumptions as to what you're going on about.
This applies to "dq" above, as well as many other acronyms and abbreviations. This article[6] discusses the issue at some length:
Most abbreviations do require a definition. In
any case where readers might be confused by TLAs
three letter abbreviations), it's important that
they be defined in the text or in a Table of
Abbreviations. A research proposal or article
with complicated and confusing abbreviations is
one that will quickly face rejection. The problem
is that authors become so familiar with
abbreviations that they forget to define them.

[6] I'm using "abbreviations" here to mean abbreviations (e.g., Amex for American Express), acronyms (e.g. NAFTA for North Amerian Free Trade Agreement) and initialisms (e.g., TCP for Transmission Control Protocol, FBI for Federal Bureau of Investigation).
