Cookie Transparency

Detailed Cookie Policy

Full disclosure on technical cookies, browser local storage, and Google AdSense advertising cookies.

What Are Cookies? A cookie is a small text file transmitted to your browser by websites you visit. It enables the site to remember information about your visit (such as preferred language or display choices), making your next visit smoother and more personalized. At PDFListo, we value user autonomy and restrict cookie usage to strictly necessary functional elements and verified programmatic advertising.

1. Categories of Cookies Deployed on PDFListo

In accordance with the EU ePrivacy Directive and international data regulations, cookies utilized on this platform fall into two clearly defined groups:

A. Strictly Necessary & Functional Cookies

These cookies are essential for navigating the site and enabling requested features:

consent_status: Retains your consent settings from the cookie notification bar (lifetime: 12 months).
preferred_lang: Preserves language preferences across visits (lifetime: session or 1 year).
Service Worker Cache Storage: Browser-side resource caching enabling offline tool functionality (PWA architecture).

B. Programmatic Advertising Cookies (Google AdSense)

These cookies finance our operational costs, ensuring free access for users globally:

__gads / __gpi: Google AdSense cookies that measure ad performance, prevent fraud, and control frequency capping (lifetime: 13 months).
IDE / test_cookie (DoubleClick): Used to evaluate campaign effectiveness and deliver non-repetitive ads across Google partner networks.

2. Third-Party Cookies & Data Transfers

Google LLC adheres to the EU-U.S. Data Privacy Framework, guaranteeing adequate data safeguards for international transfers. Third-party vendors participating in Google AdSense comply with strict vendor certification standards.

3. How to Manage and Disable Cookies

You can accept, customize, or disable cookies at any time via your browser settings. Refer to official vendor instructions:

4. Policy Updates & Contact

We may update this policy periodically to reflect statutory amendments or technical updates. For inquiries regarding cookie usage, reach out to soporte@pdflisto.org.

3. Comprehensive Cookie Audit & Inventory Table

In accordance with GDPR transparency guidelines and the ePrivacy Directive, the following table details every cookie and local storage key utilized across the PDFListo domain:

Cookie Key	Provider	Purpose	Duration
consent_status	PDFListo	Records user consent selection for privacy banners	12 Months
__gads / __gpi	Google AdSense	Fraud detection, ad frequency capping, and ad performance	13 Months
IDE / test_cookie	Google DoubleClick	Contextual ad matching and anonymous click measurement	1 Year

4. Google Consent Mode v2 & Cookieless Measurement

PDFListo fully supports Google Consent Mode v2. When a user rejects advertising personalization or opts out through our banner controls, Google AdSense tags dynamically adapt to serve non-personalized advertisements via ephemeral cookieless pings that do not store cross-site tracking markers.

5. Browser Configuration & Revocation of Consent

You may configure your browser software to block or alert you about all incoming cookies. For detailed guidance, consult official browser vendor support documentation: Google Chrome, Mozilla Firefox, Apple Safari, and Microsoft Edge.

6. Technical Distinctions: Cookies vs. Client Web Storage

Modern web applications rely on distinct client-side storage technologies. It is vital to understand the architectural boundaries between tracking cookies and client-side processing caches:

HTTP Cookies: Small header tokens sent to web servers on each request. On PDFListo, cookies are strictly restricted to user consent records and Google AdSense anti-fraud metrics.
LocalStorage: Persistent browser key-value stores used strictly to remember user interface preferences (such as dark mode and language preference). LocalStorage data is never transmitted across network headers.
SessionStorage: Ephemeral page memory discarded immediately when a tab is closed. PDFListo uses SessionStorage solely to coordinate page thumbnails inside the client organizer tool.
IndexedDB / CacheStorage: Local browser storage allocated by our Progressive Web App (PWA) Service Worker to cache WebAssembly binaries, allowing full offline execution without internet connectivity.

7. Right to Object & Supervisory Authority Recourse

Under GDPR Article 21 and the ePrivacy Directive, you possess the right to object at any time to the processing of your data for advertising purposes. You may enforce this right by blocking advertising cookies via our consent banner, utilizing browser-level privacy controls, or lodging a formal inquiry with our privacy officer at soporte@pdflisto.org.

8. Frequently Asked Questions Regarding Cookies & Privacy

Why does PDFListo display a cookie banner if processing is 100% local?

Under the European Union ePrivacy Directive and GDPR statutory mandates, websites operating within or accessible from the European Economic Area must obtain unambiguous prior consent before placing non-essential advertising cookies (such as Google AdSense tokens), even when file transformations occur completely client-side in RAM.

What happens if I reject all non-essential cookies?

You retain full, unhindered access to every PDF tool across our entire suite with zero restrictions. When advertising cookies are declined, our advertising network serves non-personalized contextual ads without storing persistent user tracking beacons or cross-site tracking markers.

How can I permanently purge cookies from my browser?

You may purge stored cookies at any time via your browser settings (Settings > Privacy and Security > Clear Browsing Data > Cookies and other site data). Upon returning to PDFListo, the consent interface will re-render, enabling you to specify your preferences anew.

Do Not Track (DNT) & Global Privacy Control (GPC) Signals

PDFListo respects modern consumer privacy signals including Do Not Track (DNT) and the Global Privacy Control (GPC) specification. When your browser transmits a DNT: 1 or GPC signal header, our client runtime automatically disables advertising personalization cookies and serves purely non-personalized contextual ads, aligning with the highest international privacy standards.

Additionally, our technical compliance team routinely reviews emerging privacy frameworks across all international jurisdictions, including Swiss FADP and Brazilian LGPD, ensuring that our cookie consent parameters remain fully compliant with the most rigorous global data protection directives.
