Privacy Policy

Single Page View for Google Docs
KNF Publications, Inc., also trading as Cherry Task
Effective date: 20 August 2026 · Last updated: 21 August 2026

This policy explains what we do — and mostly do not do — with information when you use our Chrome extension, visit our website, or choose to make a donation.

Who we are

KNF Publications, Inc. is a Maryland corporation. We also trade under the name Cherry Task, so a donation may appear on your card or bank statement as Cherry Task rather than KNF Publications. Both names mean the same company, and that company is the data controller responsible for this policy.

KNF Publications, Inc.
267 Kentlands Boulevard, PMB #5045
Gaithersburg, MD 20878
United States

You can reach us any time at support@knfpub-inc.com. A real person reads it.

What this policy covers

We call the second and third of those, together, the “Site.”

The Extension is free. We do not sell the Extension, a subscription, or any other product or service. Payments on the Site are entirely optional donations that support continued development, and you get the same Extension whether you donate or not.

1. The Extension collects nothing

Using the Extension does not require an account, an email address, or a payment. We do not run a server that receives anything from it. When our website says “No data collection,” that is about the Extension — a donation is a separate, optional act, and it is described in section 3.

In particular, the Extension:

  • does not collect, transmit, or store the contents of your Google documents;
  • does not collect your Google account, name, or email address;
  • does not use analytics, advertising, or tracking of any kind;
  • does not use cookies;
  • does not sell or share personal information.

The Extension only runs on Google Docs document pages (https://docs.google.com/document*). It does not run on Gmail, Drive, or any other website. It does not request Chrome’s broad tabs permission — the only website permission it asks for is the one covering Google Docs documents.

Your settings stay on your device

The Extension saves four small preferences using Chrome’s extension storage:

Setting What it remembers
singlePageViewEnabled whether single page view is turned on
shortcutBindings the keyboard shortcuts you have chosen
restoreZoomOnDisable whether to restore your zoom level when you turn the view off
focusGoToPage a temporary note of which field to focus, kept only for the current browser session

We deliberately do not use Chrome’s “sync” storage. Sync storage would copy your settings to Google’s servers and push them to your other computers. We use local and session storage instead, so your settings stay in your browser profile on the machine where you set them.

We cannot read any of it. The Extension contains no networking code whatsoever — no requests, no analytics calls, no remote scripts. Uninstalling the Extension deletes all of it.

Chrome, Google Docs, and the Chrome Web Store are Google’s products. What Google does with your data is covered by Google’s Privacy Policy, not by this one.

2. Our website

You can read every page on www.knfpub-inc.com without giving us anything. We run no advertising, no analytics, and no visitor tracking of any kind, and nothing we run directly loads unless you click something that asks for it.

Four service providers help deliver the site, and they see what any web server sees:

  • Brizy Cloud — builds and hosts the website, and delivers its images and code through its content delivery network.
  • Bunny Fonts (BunnyWay d.o.o., Slovenia) — serves the typefaces the site uses. We chose it because it is designed not to track or profile the people who load fonts from it.
  • ThriveCart — provides the donation checkout. A small script from ThriveCart loads with the page so the donate button works, but by itself it does nothing with your information — it does not create a checkout, load a checkout page, or set a cookie. That only happens if you click the button, which opens the checkout in a popup. See section 4 for what that click sets.
  • Moosend — runs our mailing list. Nothing from Moosend loads on the page at all until you click our “Subscribe” button, which opens a small window, on our page, showing a sign-up form Moosend hosts. See section 4 for what that click involves.

To send you a page, these providers necessarily receive technical information including your IP address, browser type, and the address of the page you asked for. We do not use Brizy or Bunny Fonts for analytics or advertising, and we do not receive visitor reports from them.

3. Donations

If you choose to donate, the checkout is hosted by ThriveCart. We never handle or store your card details ourselves.

What the donation form asks for

Only your email address — so we can send a receipt and reach you about a refund or a problem — and your payment details, which go to the payment provider rather than to us. Our own form does not ask for your name, postal address, or phone number, and we never collect them. Stripe’s own card step separately offers to ask for a phone number, on by default and easy to skip — see below.

Who processes the payment

ThriveCart runs the checkout. The company that actually moves the money depends on the method you pick:

  • Stripe, if you pay by card or by one of the methods Stripe offers at checkout — which may include Stripe Link, Google Pay, Amazon Pay, Cash App Pay, Klarna, or a US bank transfer; or
  • PayPal, if you choose PayPal.

Those companies receive the details needed to complete your donation and handle it under their own privacy policies. We never receive your full card number. What comes back to us from ThriveCart is your email address, the amount, and whether the payment succeeded.

After your donation goes through, the checkout expands to show a “Save my information for faster checkout” section — checked by default — asking for your email and phone number to set up a Stripe Link wallet you can reuse at other Link merchants. This appears only once your payment has already completed, so it has no effect on your donation either way. None of it reaches us: we never receive your phone number, and it plays no part in completing your donation. Stripe’s own terms and privacy policy govern the Link account, if you create one, and that relationship continues after your donation is finished.

ThriveCart uses its own suppliers to run its service, and publishes the current list in section 7.2 of its Data Processing Addendum. We link to it rather than copying it, because ThriveCart updates it from time to time.

Fraud prevention

The checkout uses hCaptcha, operated by Intuition Machines, Inc., to tell people apart from automated bots. hCaptcha examines technical signals such as your IP address, how long you have been on the page, and your mouse movements, and it sets its own cookies. This protects the checkout from fraud and abuse. See hCaptcha’s privacy policy.

Optional emails about the Extension

Two places on the Site let you opt in, and both use the same checkbox or button: “Yes, please notify me of new features, updates, and other opportunities. (Occasional email. No spam.)” One is on the donation checkout, unticked by default. The other is our “Subscribe” button, which opens a small window on our page showing a sign-up form hosted by Moosend. Either way — ticking the checkbox at checkout, or entering your email in the Subscribe form and submitting it — adds your email address to our list with Moosend, and we may occasionally write to you about the Extension. If you leave the checkbox unticked, or never submit the Subscribe form, no email address is added.

You can leave at any time using the unsubscribe link in any email we send, or by writing to support@knfpub-inc.com. Withdrawing your consent is as easy as giving it, and it does not affect anything we lawfully did with your email address before you withdrew.

Privacy policies of the companies involved

4. Cookies and Do Not Track

The Extension does not use cookies.

We set no cookies of our own. Nothing we run directly on www.knfpub-inc.com stores a cookie on your device. Two providers set their own, described below, only after you click something asking for what they provide, and neither is used for advertising or cross-site tracking.

Clicking Subscribe loads Moosend’s form. Nothing from Moosend loads when you visit the Site. Clicking our “Subscribe” button opens a small window, on our page, that loads a sign-up form Moosend hosts. That load sends Moosend the same kind of technical information any web request sends, and may set cookies of its own — for instance to remember that you already submitted the form. If you never click Subscribe, none of that happens. See Moosend’s privacy policy.

Clicking the donate button sets one. Our home page carries a “buy me a coffee” button. Clicking it opens the checkout in a popup, provided by ThriveCart, and that action sets a session cookie called thrivecart_v2 — one on .thrivecart.com and one on .cart.knfpub-inc.com. ThriveCart uses it to keep that checkout session working so your details survive the steps of the form. If you never click the button, this cookie is never set.

That cookie holds no profile of you. It is not used for advertising, analytics, or tracking you across other websites, and it expires when your browser session ends. ThriveCart also shows visitors in the European Union its own cookie notice inside the checkout. If you go on to use the checkout, hCaptcha may set cookies of its own for the fraud checks described in section 3.

Do Not Track

Some browsers can send a “Do Not Track” signal. There is no common industry standard for what a website must do when it receives one. We do not track you across other websites, so there is nothing for us to switch off there, and we do not respond to those signals differently.

We also do not allow third parties to collect personally identifiable information about your activity across different websites through our Site.

5. Why we use this information

Stated plainly, and regardless of where you live:

  • Your donation email address and payment details — to take the donation, send you a receipt, answer your questions, and handle refunds.
  • A record of the donation — to keep accurate business and tax records, as any company must.
  • Your email address for updates — only if you ticked the box asking for them.
  • Your Extension settings — to make the Extension behave the way you told it to. These never leave your device, so we never see them.

If UK or EU data protection law applies to you, our lawful bases are:

  • Performance of our agreement with you — taking your donation, sending the receipt, and handling a refund.
  • Our legitimate interests — keeping accurate financial records, and protecting the checkout from fraud and abuse.
  • Your consent — sending you updates about the Extension. You may withdraw it at any time, as described in section 3.

We do not make automated decisions about you that produce legal effects or similarly significant effects.

6. Who we share information with

We do not sell personal information, and we never have. We do not share it for cross-context behavioral advertising. We have no advertising relationships of any kind.

Information about a donation is shared only with:

  • ThriveCart, which runs the checkout;
  • the payment provider you chose, and its own suppliers;
  • hCaptcha, for the fraud checks at checkout;
  • Moosend, which receives standard technical information (like your IP address) if you click our Subscribe button, and your email address if you tick the checkbox at checkout or submit the Subscribe form;
  • our accountant or professional advisers, and any authority we are legally required to respond to.

There is nothing to share about your use of the Extension, because the Extension never sends us anything.

7. How long we keep it

Your Extension settings stay on your device until you change them or uninstall the Extension. We keep donation records for as long as we need them for receipts, refunds, tax, and bookkeeping, and then delete them or strip them of anything identifying. If you asked for updates, we keep your email address on the list until you unsubscribe or ask us to remove it. ThriveCart, Moosend, and the payment providers keep their own records under their own policies.

8. Your rights

Wherever you live, you can ask us what personal information we hold about you, ask us to correct it, ask us to delete it, ask for a copy, or object to what we are doing with it. Write to support@knfpub-inc.com from the address you used, and we may need to check it is really you before we act.

If you are in the EEA, the UK, or Switzerland

You have the rights of access, rectification, erasure, restriction of processing, objection, and data portability, and the right to withdraw consent at any time. You also have the right to complain to your local data protection authority, and you may do so in the country where you live, where you work, or where you think something went wrong.

If you are in California

We are a very small company, and the California Consumer Privacy Act does not currently apply to us — we meet none of the thresholds that would make it apply. We honor the substance of it anyway: you can ask what we hold, ask us to correct or delete it, and receive a copy. We do not sell or share personal information as that law defines those words, so there is no opt-out for you to exercise. We will never treat you differently for asking.

9. Children

The Extension and the Site are not directed at children. We do not knowingly collect personal information from anyone under 16, or under 13 in countries that have set that lower age under the GDPR. If you believe a child has sent us personal information, write to us and we will delete it.

10. Where information is processed

We are based in the United States, and our service providers may process information in the United States or in other countries where they or their suppliers operate.

Where information is transferred out of the UK or the EEA, the transfer is covered by the safeguards those providers have put in place. ThriveCart’s Data Processing Addendum, for example, commits it to using Standard Contractual Clauses approved under Article 46 of the GDPR, or an equivalent lawful transfer mechanism.

11. Changes to this policy

If we change this policy in a way that matters, we will update the “Last updated” date at the top and post the new version at this address. The version published here is always the current one.

12. Chrome Web Store disclosures

Required by Google for extensions published on the Chrome Web Store:

  • Single purpose — to show one page of a Google Doc at a time in Print layout, and to jump to a page by number.
  • Why it needs the storage permission — to save your own preferences on your own device, as listed in section 1.
  • Why it needs permission for Google Docs documents — to apply the zoom and page navigation inside the document you have open. It is never used to read, collect, or transmit document contents.
  • Remote code — none. The Extension runs only the code shipped in its package.
  • User data — none is collected, used, or transferred by the Extension. We do not sell or transfer user data to third parties, use it for anything unrelated to the Extension’s single purpose, or use it to determine creditworthiness or for lending.

The short version: the Extension is free and collects nothing. We set no cookies directly. Clicking our ThriveCart donate button or our Moosend Subscribe button each load a small window of their own and may set cookies, as described above — nothing loads until you click. If you donate, we learn your email address and the amount; if you subscribe, we learn only the email you give us — either way, you only hear from us again if you asked to.

This policy describes how we actually operate. It is written to be read, not to be impressive, and it is not legal advice. See also our Terms of Use.
