Cookies Policy
This page explains how PDFkoi uses cookies and browser storage to support essential site features.
Minimal usage
We aim to use only the storage needed to make the site work and remember your preferences.
No ad tracking
This policy does not permit advertising cookies or cross-site tracking for PDF content.
Stored on your device
Preference data is typically stored in your own browser, not uploaded with your files.
Privacy-first design
PDF processing stays in your browser, which reduces the need for server-side identifiers.

1. What this policy covers
This Cookies Policy explains how PDFkoi uses cookies, local storage, session storage, and similar browser technologies when you visit the site or use our PDF tools.
Because our product is designed to process files in the browser, we try to keep storage usage limited to essential functionality, preferences, and product usability.
2. What we mean by cookies and similar technologies
Cookies are small text files placed in your browser. Similar technologies include local storage, session storage, and browser-managed preference data. In practice, some site features may rely on browser storage instead of classic cookies.
For clarity, this policy uses the phrase "cookies and browser storage" to cover all of these technologies together unless a section says otherwise.
3. How PDFkoi uses cookies and browser storage
| Item | Purpose | Technology | Duration |
|---|---|---|---|
| Language preference | Remembers the language you selected so the site opens in your preferred locale. | Local storage | Until you clear browser data |
| Recent files and saved work | Keeps recent activity and in-progress items on your own device for convenience. | Local storage | Until you clear browser data |
| Essential site state | Supports core interface behavior such as tool state, dialogs, and user preferences. | Session storage or local storage | Session or until you clear browser data |
4. Categories of usage
Essential functionality
These items help the site operate reliably, keep interface state consistent, and support features that users reasonably expect from a browser-based tool.
Preference storage
Preference storage helps remember settings such as language choice or other non-sensitive product preferences so that you do not need to reconfigure the site every visit.
Local productivity features
Some tools may preserve recent actions or in-progress information on your own device to improve usability after refreshes or interrupted sessions.
5. What we do not use these technologies for
- We do not use cookies to upload or inspect the contents of your PDF files.
- We do not use advertising cookies to build behavioral ad profiles from your document activity.
- We do not rely on cookies to move your files to third-party PDF processing services.
- We do not claim a right to use browser storage to read documents outside the tools you choose to run.
6. Third-party services
If the site links out to services such as GitHub or X, those platforms may set their own cookies when you visit them. Their cookie behavior is governed by their own policies, not this page.
This policy covers cookies and browser storage used for the PDFkoi site experience itself.
7. How to control or delete cookies and local storage
You can control cookies and browser storage through your browser settings.
- Delete existing cookies and site storage from your browser privacy settings.
- Block some or all cookies if your browser offers that option.
- Clear local storage or site data for PDFkoi if you want to remove remembered preferences.
Please note that disabling all cookies or site storage may affect site functionality, including your saved preferences and convenience features.
8. Changes to this Cookies Policy
We may update this policy from time to time to reflect changes in site functionality, legal requirements, or product design. When we do, we will update the date shown at the top of this page.

Practical summary
PDFkoi is built to do most of its work in the browser. That means the site generally needs only limited storage for preferences and usability, rather than invasive tracking infrastructure.
