Cookie Policy

This Cookie Policy explains how PDFTEQ (“we”, “us”) uses cookies and similar technologies (such as LocalStorage and SessionStorage) to recognize you when you visit our website. It explains what these technologies are, why we use them, and your rights to control our use of them.

1. Technical Definition: What are Cookies?

Cookies are small text files containing a string of alphanumeric characters (JSON or String data) that are placed on your device by a web server. They allow our website to "remember" your actions or preferences over time.

2. Categories of Cookies We Use

A. Essential / Strictly Necessary Cookies

These cookies are fundamental to the "Client-Side Architecture" of PDFTEQ. Without these, services like merging multiple files or maintaining your settings during a session would not function.

• Purpose: Maintaining tool state (e.g., remembering which files you added to the merger).
• Opt-out: Not possible (Service would break).

B. Performance & Analytics Cookies (Google Analytics)

We use Google Analytics (GA4) to collect anonymized telemetry data. This helps our engineering team understand:

• Which tools are most popular (e.g., Merge vs. Compress).
• Load times and performance bottlenecks.
• User geography (Country/City level only).

C. Advertising & Monetization Cookies (Google AdSense)

To keep PDFTEQ free for students, we use Google AdSense to display advertisements. Google and its partners use cookies to serve ads based on your prior visits to our website or other websites.

• DoubleClick Cookie: Enables Google and its partners to serve ads based on your visit history.
• Personalization: You may see ads related to your interests.

3. LocalStorage vs. Cookies

PDFTEQ minimizes the use of traditional HTTP Cookies. Instead, we utilize modern HTML5 LocalStorage for performance.

• Data Stored: UI Preferences (Dark Mode preference), Tool configurations.
• Privacy Benefit: Data in LocalStorage is purely client-side and is not sent to our servers with every HTTP request.

4. Managing Your Preferences

You have the right to decide whether to accept or reject cookies.

• Browser Controls: You can set your web browser controls to accept or refuse cookies. If you choose to reject cookies, you may still use our website, though some functionality may be restricted.
• Ad Settings: You can opt-out of personalized advertising by visiting Google Ad Settings.
• Industry Opt-Out: Visit AboutAds.info for broader control.

5. Updates & Contact

We may update this policy to reflect changes in our tech stack (e.g., upgrading to new Analytics versions). For technical questions regarding our state management:
