What FoxQuill holds, what leaves your computer, and what you can ask for.

Last updated October 13, 2026 · FoxQuill, Nebraska, USA

The short version#

Your writing stays on your computer. FoxQuill has no account, no cloud, and no telemetry. It never reports what you write, how long you write, or that you opened it.

The website, foxquill.studio, does count visits. See “The website” below.

Who is responsible#

FoxQuill, a sole proprietor based in Nebraska, in the United States. “We” and “us” below mean that business. Write to foxquillstudio@gmail.com.

What FoxQuill keeps, and where#

Everything FoxQuill knows is in one folder on your computer:

SystemFolder
Windows%APPDATA%\FoxQuill\data
Linux~/.config/FoxQuill/data
macOS~/Library/Application Support/FoxQuill/data

A copy installed before the app was called FoxQuill keeps the folder it made then.

We have no copy of it and no way to get one.

What ever leaves your computer#

Only these, and only when you use the matching feature.

Activating a license#

  • Goes to: Polar Software Inc., the shop.
  • Carries: your license key, the activation id, the app version, and the name of your computer, which is used as a label so you can tell your devices apart.
  • Why: to check the key is valid and to count your three devices.
  • Kept: by Polar, for as long as your license exists.

Starting a free trial#

  • Goes to: the FoxQuill trial service, a small Cloudflare Worker.
  • Carries: a one-way hash of your machine, which cannot be turned back into a name, plus the day the trial started and the day it ends.
  • Why: so a reinstall does not hand out a second trial.
  • Kept: until the trial has been over for a year.

Checking for updates#

  • Goes to: GitHub.
  • Carries: nothing about you. It asks a public page which version is newest. GitHub sees the request, as any web server sees any request.

Looking a word up#

  • Goes to: Wiktionary, or Datamuse, or a provider you added yourself.
  • Carries: the one word you looked up. Not the sentence, not the paragraph.
  • Kept: by them, under their own policies. FoxQuill caches the answer on your computer for thirty days so the same word is not asked twice.

Spell check in another language#

  • Goes to: Google, at redirector.gvt1.com, on Windows and Linux.
  • Carries: nothing about you or your writing. It asks for one dictionary file, the first time a language other than English is in use, whether you chose it or your computer is set to it. English comes with FoxQuill, and a Mac uses its own spell checker. Google sees the request, as any web server sees any request.

Sharing a link#

  • Goes to: the FoxQuill share service, a small Cloudflare Worker.
  • Carries: the chapter or book you chose, encrypted before it leaves your computer. The service cannot read it. The key travels only inside the link you send, in the part after the #, which browsers never send to servers. Also carried: what the link allows, when it stops working, and a hash of the password if you set one.
  • Also kept: any comment or suggestion a reader leaves, also encrypted, and the display name they typed for themselves.
  • Kept: until you revoke the link or it expires, and then deleted.

AI features#

Off by default. If you turn them on, FoxQuill sends only what the AI can read, and only to the server address you configured yourself. You set what it can read with “The AI can read this” on scenes, notes, and card fields, and with the AI choice on each card. The book’s description and style guide are always included. That may be a program on your own machine, in which case nothing leaves it at all. We run no AI server and see nothing.

What FoxQuill does not do#

  • The program sends no telemetry, no usage statistics, and no crash reports.
  • No advertising and no advertising identifiers.
  • No selling or sharing of anything, because there is nothing to sell.
  • No account, so no email address unless you buy, and then Polar holds it, not FoxQuill.

The website#

The website, foxquill.studio, is hosted by Lovable. Lovable adds a visitor counter to every page. The counter belongs to the website, not to the FoxQuill program.

  • Sets: no cookie of its own. It gives each visit a random number, not a name, so the pages of one visit count as one visit.
  • Carries: the page you opened, that random number, and how fast the page loaded.
  • Why: so FoxQuill can see how many people visit, and which pages they read.
  • Kept: by Lovable, under its own privacy policy. Lovable also sees each request, as any web server does, including your IP address, your browser, and the page that sent you there.

The host sets two cookies of its own on the website, and nothing else sets one. Neither holds your name.

  • __dpl holds a value the host’s servers made, not a name. It expires after one day.
  • __cf_bm is a Cloudflare cookie that helps tell visitors from bots. It expires after 30 minutes.

Cookies#

The FoxQuill program keeps two kinds of cookie inside itself. Neither leaves your computer, and each lasts a year.

  • foxquill-plan-view- followed by a book’s id, one for each book. It holds the view of the Plan tab you last picked in that book.
  • foxquill-theme. It holds the theme you last chose, so that the pages outside a book, such as the book list, open in it.

The website sets the two cookies described under “The website”, __dpl and __cf_bm. If you pick a theme there, your browser remembers it in its own storage, and that is sent nowhere.

The share viewer page keeps one thing in the reader’s browser: the display name they typed, so they are not asked again. It is stored on their own machine and sent nowhere except with a comment they choose to leave.

Your rights#

You can ask what is held about you, ask for it to be corrected, and ask for it to be deleted.

In practice there is very little to ask about. We hold no copy of your writing. Purchase records are held by Polar, whose own privacy policy applies. Trial records are a hash and two dates, and can be deleted on request. Share links you revoke yourself. Website visit counts are held by Lovable and carry no name.

Write to foxquillstudio@gmail.com. You will get an answer within 30 days.

Children#

FoxQuill is not aimed at children and collects nothing from anyone knowingly.

Changes#

If this notice changes, the new version is published with the release it applies to, and the date at the top changes.
