Cookie Policy – FileDiffs
Last Updated: April 2026
Effective Date: April 2026
This Cookie Policy explains how FileDiffs uses cookies and similar technologies to improve functionality, security, and user experience while respecting your privacy. We use these technologies to maintain session stability, remember your preferences, and ensure the platform remains secure. We do not use cookies to access your files or for intrusive tracking, and all implementations are designed to support a smooth, reliable experience while keeping your data private and fully under your control.
1. What Are Cookies?
Cookies are small text files that are stored on your device when you visit a website, helping the platform recognize your browser, maintain session continuity, and remember your preferences for a smoother experience. They play an important role in ensuring that features work reliably as you navigate between tools and pages. In addition to standard cookies, our system may use browser-based technologies such as local storage and session storage to temporarily save settings like interface preferences, layout choices, or tool configurations. These technologies operate entirely within your browser environment, meaning they stay on your device and are not used to access, read, or store the content of the files you compare.
2. Why We Use These Technologies
We follow a strict data-minimization approach, which means cookies are used only when they serve a clear and necessary purpose—such as improving performance, maintaining stability, and enhancing the overall user experience. These technologies help keep the platform responsive during file comparison, reduce loading times by caching essential resources, and provide basic protection against security threats like automated or malicious traffic. They also allow the website to remember your preferences, such as display settings or layout choices, so you don’t have to reconfigure them each time you return. In addition, limited, aggregated usage insights help us understand how the platform is used, allowing us to improve features over time while keeping data anonymous. Importantly, we do not use cookies to access your files or interact with any sensitive document content, ensuring your data remains private and under your control.
3. Types of Cookies We Use
Our platform uses a limited set of cookies, each designed to support a specific function such as maintaining platform stability, improving performance, or enhancing user experience. We categorize these cookies to provide clear transparency about how they work and why they are used, while ensuring that your privacy remains protected at all times.
a. Essential Cookies (Required)
Essential cookies are necessary for the basic operation of our services and enable core functionality across the website. These cookies support key features such as page navigation, secure session management, and access to file comparison tools. Without them, certain parts of the site may not load correctly or function as expected. These cookies do not collect personal data or track your activity across other websites—they are strictly used to ensure the platform works reliably and securely during your session.
b. Performance & Analytics Cookies
Performance and analytics cookies help us understand how users interact with FileDiffs in a broad, anonymous way. They collect aggregated information such as page usage, feature engagement, and general system performance metrics. This data allows us to identify technical issues, improve loading speeds, and optimize the overall experience for different devices and browsers. Importantly, this information does not identify individual users and is never used for profiling or intrusive tracking.
c. Preference Cookies
Preference cookies are used to remember your settings and personalize your experience on FileDiffs. This may include your chosen theme (such as dark or light mode), layout preferences, or specific tool configurations. By storing these settings locally, the platform can provide a consistent and efficient experience each time you return, without requiring you to reconfigure your workspace. These cookies are optional but enhance usability and convenience.
d. Advertising Cookies
Advertising cookies are used through trusted partners such as Google AdSense to support the free availability of FileDiffs. These cookies may track general browsing patterns to deliver ads that are more relevant and reduce repetition. They help ensure that advertising remains useful rather than disruptive.
FileDiffs does not control how third-party advertisers manage their cookies, and their practices are governed by their own privacy policies. Importantly, these cookies do not access, read, or interact with the files you compare, ensuring that your document data remains private and separate from any advertising activity.
4. Third-Party Cookies
Some cookies on our website may be set by trusted third-party services that support essential platform functions such as advertising, content delivery, and security. These may include providers like Google AdSense for advertising and other infrastructure partners that help ensure fast and reliable performance across different regions.
These third parties operate independently and have their own privacy and data-handling practices. We do not control how these external services collect, store, or use data through their cookies. We recommend reviewing the privacy policies of these providers to better understand how your information may be handled when interacting with third-party features on our platform.
5. Google AdSense & Advertising
To keep FileDiffs free and accessible, we use Google AdSense to display advertisements. Google and its partners may use cookies, including the DoubleClick cookie, to serve ads based on your previous visits to this website or other websites across the internet. This helps ensure that ads are more relevant and less repetitive.
You have full control over how personalized ads are shown to you. You can manage your preferences or opt out of interest-based advertising at any time by visiting Google Ads Settings or www.aboutads.info. Even if you choose to opt out, you may still see non-personalized (contextual) ads based on the content of the page rather than your browsing history.
6. Cookie Duration
Cookies may remain on your device for different periods depending on their purpose and functionality. Some cookies are temporary, while others are designed to remember your preferences over time.
Session cookies are short-lived and are automatically deleted when you close your browser, helping manage your activity during a single visit. Persistent cookies remain on your device for a limited duration, allowing the platform to remember settings such as preferences or configurations for future visits.
You can review, manage, or delete cookies at any time through your browser settings, giving you full control over how long they are stored and used.
7. Your Control Over Cookies
You have full control over how cookies are used on your device, and most modern browsers provide simple tools to manage these settings. You can choose to view and delete stored cookies, block all or specific types of cookies, or use private/incognito browsing modes that automatically clear data after your session ends. These options allow you to customize your privacy preferences based on your comfort level.
While disabling cookies is entirely your choice, it may affect certain convenience features—such as saved preferences, layout settings, or session continuity. However, the core functionality of FileDiffs, including file comparison, will remain accessible even if cookies are limited or disabled.
8. Privacy & Data Separation
It is important to clearly distinguish between cookies and how FileDiffs processes your files. Cookies are used only for website functionality, performance, and user experience—they are completely separate from the file comparison process.
All file processing happens locally within your browser, meaning your documents are never accessed, stored, or transmitted through cookies or any tracking technology. This separation is a key part of our privacy-first approach, ensuring that your sensitive data remains private, secure, and fully under your control at all times.
9. Updates to This Policy
We may update this Cookie Policy periodically to reflect changes in technology, legal requirements, or improvements to the FileDiffs platform. As we continue to enhance our tools and infrastructure, we want to ensure that our policies remain accurate, transparent, and aligned with current standards.
Any updates will be published on this page along with a revised effective date, so you can easily stay informed about how cookies are used and managed. We encourage users to review this page occasionally to remain up to date.
