Privacy Policy

Last updated August 22, 2026 · Applies to the PDF Deckle browser extension

The short version

PDF Deckle collects nothing. There is no server, no account and no analytics. Your documents are opened, edited and saved entirely on your own computer.

1. Who this covers

This policy explains how the PDF Deckle browser extension ("the extension", "we") handles information. It applies to the extension published on the Chrome Web Store and to equivalent builds for other Chromium-based browsers such as Microsoft Edge, Brave, Opera and Arc.

By installing the extension you agree to this policy. If you do not agree with it, please uninstall the extension.

2. Information we collect

We collect no information whatsoever. Specifically, the extension does not collect, transmit or store any of the following:

  • Personally identifiable information — name, address, email address, age or identification number.
  • Health information.
  • Financial and payment information.
  • Authentication information — passwords, credentials, security questions or PINs.
  • Personal communications — emails, texts or chat messages.
  • Location — IP address, GPS coordinates or any other location data.
  • Web history — the pages you visit or the sites you spend time on.
  • User activity — clicks, keystrokes, mouse movement, scroll position or analytics of any kind.
  • Website content — text, images, sound, video or hyperlinks from the pages you browse.
  • The contents of your documents — the PDFs, images and Office files you open in the extension.

There is no telemetry, no crash reporting, no advertising identifier, no cookie and no usage measurement.

3. How your documents are handled

When you open a file in PDF Deckle, the browser reads it from your disk into the memory of the extension's own tab. All processing — converting, merging, splitting, editing, encrypting, redacting — is performed there by code bundled inside the extension.

When you save, the result is written back to a location you choose on your own computer. At no point is the file, any part of it, or any description of it sent anywhere.

Your documents are not stored by the extension. The working copy exists only in the memory of that tab. Close the tab and it is gone. There is no history, no cache, no recent-files list and no recovery of past sessions.

You can verify this yourself in about ten seconds: disconnect from the internet, then use any tool in the extension. Everything continues to work, because nothing ever depended on a network connection.

4. Permissions, and why each one exists

Browser extensions must declare the capabilities they use. PDF Deckle requests the minimum set below and nothing else. This is the complete list from the published manifest.

Permission Why it is needed What it does not do
storage Remembers which browser tab the workbench is open in, so clicking the toolbar icon returns you to it instead of opening duplicates. Uses session storage, which the browser clears when you close it. Never holds document contents, settings tied to you, or anything beyond a single tab number.
contextMenus Adds the single "Open PDF Deckle workbench" entry to the right-click menu. Does not read the page you right-clicked, or what you selected on it.

Permissions deliberately not requested

The extension declares no host permissions and installs no content scripts. In practical terms this means it has no ability to see, read or alter any website you visit — including this one. It also cannot run in the background on any page.

// the complete permission declaration in manifest.json
"permissions": ["storage", "contextMenus"],
// no "host_permissions" key, and no "content_scripts" key

The extension's content security policy is set to script-src 'self', which means the browser itself refuses to let it load or execute any code fetched from the internet. Every library it needs is packaged inside the download.

5. Third parties

There are none. PDF Deckle contains no analytics service, no advertising network, no error-reporting service, no content delivery network and no external fonts. It makes no requests to any server, including our own.

We do not sell, rent, trade or transfer information to third parties, because no information is collected in the first place.

6. Limited use

In accordance with the Chrome Web Store User Data Policy, we confirm that PDF Deckle:

  • does not collect or transmit user data;
  • does not sell or transfer user data to third parties;
  • does not use or transfer user data for purposes unrelated to the extension's single purpose;
  • does not use or transfer user data to determine creditworthiness or for lending purposes;
  • does not permit humans to read user data.

The extension has a single purpose: to let you work with PDF and document files locally in your browser.

7. Children

PDF Deckle is a general-purpose document utility and is not directed at children. Because the extension collects no information from anyone, it collects none from children either, and no parental consent mechanism is required.

8. Your rights under GDPR, UK GDPR, CCPA and similar laws

These laws grant you rights over personal data held about you — to access it, correct it, delete it, port it, or object to its processing.

We hold no personal data about you. There is nothing to disclose, correct, export or erase, and no request is necessary to achieve that outcome. If you want to remove everything associated with the extension, uninstall it; because nothing is stored elsewhere, removal is complete at that moment.

No data is transferred internationally, since no data is transferred at all.

9. Security

The most meaningful security property of PDF Deckle is architectural rather than procedural: data that is never transmitted cannot be intercepted in transit, and data that is never stored on a server cannot be exposed in a server breach.

Files you work on are subject to the security of your own computer and browser. Anything you save is stored wherever you choose to put it, and is your responsibility from that point.

A note on password protection

Passwords you type into the encryption tool are used in your browser to derive an encryption key, and are then discarded. They are not recorded, transmitted or recoverable. If you lose a password you set on a document, no one — including us — can open that file.

10. Changes to this policy

If the extension's behaviour ever changes in a way that affects this policy, the policy will be updated before that version is published, and the date at the top will change. Any future version that collected data would require new permissions, which your browser would tell you about and ask you to approve.

Previous versions remain available on request.

11. Contact

Questions about this policy, or about how the extension behaves, can be sent to BunkLyf LinkedIn Page.

If you find anything in the extension that contradicts this policy, please report it — that would be treated as a serious defect.
