Privacy Policy

Co-pdf processes your documents entirely on your own device. This policy explains what is and is not collected.

Last updated: 28 September 2026

1. Your documents

Every file you open is processed locally in your browser's memory. Nothing about the contents of your documents — not the text, not the images, not the file name — is sent to us or to anyone else. When you close or reload the tab, that data is gone.

2. What is stored on your device

Small preferences are saved in your browser's local storage so the app behaves sensibly between visits — for example your chosen interface language. This never leaves your browser and you can clear it at any time through your browser's settings.

The app also registers a service worker, which caches its own program files so it keeps working offline. It caches the application, not your documents.

3. Requests the app makes

The app and its program files — including the character map and font files some PDFs need to display — are downloaded from our own host, Cloudflare. Like any web host, it necessarily receives your IP address in order to deliver the pages to you.

One feature fetches files from elsewhere: OCR (text recognition) downloads the recognition data for the language you pick from the jsDelivr content network. That request is for program data only. It does not carry your document, and it happens only when you use OCR.

4. Advertising

Advertising is not currently enabled. This section describes what will apply when it is, so that it is not a surprise.

Advertising is intended to keep Co-pdf free. When it is enabled, ads will be supplied by a third-party advertising network. That network — not us — may set cookies or read device identifiers in order to choose and measure ads, and may use your IP address and general location to do so. That is ordinary web advertising, and it is tracking; we would rather say so plainly than claim otherwise.

What will not change: the advertising network has no access to your documents. Your files are not sent anywhere, so there is nothing about their contents to share, and we never pass file names or extracted text to any advertiser or analytics service.

Where the law requires it — including the EEA, the United Kingdom and Switzerland — you will be asked for consent before any personalised advertising is loaded, and you will be able to change or withdraw that choice. Where other privacy rules apply, such as in parts of the United States, the corresponding opt-out will be offered.

5. Analytics

We use Cloudflare Web Analytics to count visits in aggregate — for example how many people open the editor, which guides are read, and roughly which countries visitors come from — so we know what to improve. It is designed not to track people:

• It sets no cookies and uses no local storage, and it does not fingerprint you or follow you across other websites.
• It records the page address (for example /privacy/), the site that linked to it, your browser and device type, your country, and how fast the page loaded.
• It never receives your documents, their names or their contents. None of that is ever part of a page address or sent anywhere.

Cloudflare processes this data for us under its own privacy policy. Because it uses no cookies and does not identify you, it does not ask for consent. Blocking it — for example with a content blocker — does not affect how the app works. We do not use any other analytics.

6. Children

Co-pdf is a general-purpose tool and is not directed at children.

7. Your rights

Because we do not collect personal data about you, there is generally nothing for us to export or delete. For anything an advertising network holds, its own policy and controls apply. You can clear everything this site has stored on your device by clearing site data in your browser.

8. Changes

If this policy changes in a way that affects you — in particular before advertising is turned on — the date at the top will change. Continuing to use the site after that means you accept the updated policy.

9. Contact

Questions about privacy can be sent to us via the contact page.
