Cookies
Policy.

This Cookies Policy explains how Transfonic ("we," "us," or "our") uses cookies and similar tracking technologies on our website located at www.transfonic.com (the "Platform"). It should be read alongside our Privacy Policy, which provides broader context on how we handle your data.

Transfonic is committed to transparency. We use a minimal set of cookies — only what is genuinely necessary to keep the Platform working, understand how it is being used in aggregate, and remember lightweight preferences on your behalf. We do not use cookies for advertising, behavioral profiling, or cross-site tracking of any kind.

By continuing to use the Platform after being presented with a cookies notice, you consent to our use of cookies as described in this policy. You may withdraw or adjust that consent at any time through your browser settings or any cookie management tool we provide.

Cookies are small text files that are placed on your device — computer, smartphone, or tablet — by a website when you visit it. They are widely used across the internet to make websites function correctly, remember your preferences, and provide website owners with anonymous information about how their sites are used.

Cookies are stored by your web browser and are sent back to the originating website each time you visit it. They cannot execute programs, deliver viruses, or access any other information on your device beyond what the website originally stored in them.

Session Cookies vs. Persistent Cookies

• Session cookies are temporary. They exist only for the duration of your browser session and are automatically deleted when you close your browser tab or window. These are primarily used to maintain state during an active file processing task.
• Persistent cookies remain on your device for a defined period after your session ends — or until you manually delete them. They are used to remember preferences or recognize returning visitors across multiple sessions.

First-Party vs. Third-Party Cookies

• First-party cookies are set directly by Transfonic and are only readable by us. They are used for core platform functionality and preference storage.
• Third-party cookies are set by external services or providers that deliver features or analytics on our behalf. They are subject to those providers' own privacy and cookie policies.

Similar Technologies

In addition to cookies, we may use similar local storage technologies such as web storage (localStorage and sessionStorage) to store lightweight session-level data. These function similarly to cookies but are stored differently in your browser. Where we reference "cookies" in this policy, the same principles apply to any similar technologies we use.

We use cookies for a small and clearly defined set of purposes. Each purpose is described in detail in the sections that follow. At a high level, cookies on Transfonic serve three functions:

• Platform operation. Essential cookies allow the Platform to function as intended — including maintaining state during file upload and processing sessions, ensuring tools respond correctly, and keeping your interaction stable throughout a visit.
• Anonymous analytics. Analytics cookies help us understand aggregate usage patterns — such as which tools are most used, where users come from geographically, and how the Platform performs over time. This data is fully anonymized and never tied to an individual identity.
• Preference storage. Preference cookies remember lightweight settings — such as your chosen interface theme — so you do not need to reconfigure them on every visit.

We do not use cookies for targeted advertising, behavioral retargeting, cross-site user tracking, or any form of personal data monetization. Every cookie we set has a specific, documented purpose and a defined retention period.

Essential cookies are strictly necessary for the Platform to operate. Without them, core features — including file uploads, processing sessions, and tool interactions — would not function correctly. These cookies do not collect any personal data and do not track your behavior for any purpose beyond maintaining the technical integrity of your active session.

What They Do

• Maintain session state during file upload and processing tasks, ensuring that your conversion or processing job is correctly associated with your active browser session.
• Enable basic security features that protect the Platform from cross-site request forgery (CSRF) and similar technical vulnerabilities.
• Ensure that requests between your browser and our servers are correctly routed and authenticated at a technical level.
• Remember transient interface states — such as which step of a multi-step tool you are currently on — within a single session.

Retention

Essential cookies are session-only. They are automatically and completely deleted when you close your browser tab or window. They are never persisted between separate browser sessions.

Can You Opt Out?

Essential cookies cannot be disabled through our cookie preference controls because doing so would prevent the Platform from functioning. You may block all cookies through your browser settings, but this will likely cause core tools to stop working correctly. We recommend keeping essential cookies enabled during any active use of the Platform.

Analytics cookies help us understand how visitors interact with the Platform in aggregate. This information is used exclusively to improve the Platform's design, performance, and content — never to identify individual users or track behavior across external websites.

What They Collect

• Which pages and tools on the Platform are visited most frequently and for how long.
• Approximate geographic region of visitors (country or broad region level — never precise location).
• How users arrive at the Platform — whether through search engines, direct entry, or referral links.
• Browser type, device category, and operating system used to access the Platform.
• Error and performance events that help us identify and resolve technical issues quickly.

What They Do Not Collect

• Individual personally identifiable information such as your name, email address, or IP address in identifiable form.
• The content of any files you upload or process through the Platform.
• Behavioral data from other websites you visit before or after Transfonic.

Retention

Analytics cookies typically persist for up to 24 months. All data collected through analytics cookies is aggregated and anonymized before analysis, meaning no individual user can be identified from the resulting data.

Can You Opt Out?

Yes. You can disable analytics cookies through your browser settings or any cookie preference tool we provide. Disabling analytics cookies will not affect your ability to use any of the Platform's file processing tools.

Preference cookies allow the Platform to remember choices you make about your experience — such as your preferred interface theme or layout settings — so that these are applied automatically on your next visit. They improve your experience by reducing the need to re-configure the same settings on every visit.

What They Store

• Interface theme preference (for example, light or dark mode if applicable).
• Any layout or display preferences you have explicitly set through the Platform's interface.
• Regional or language preferences where applicable.

What They Do Not Store

• Any file content, upload history, or processing results.
• Account information, personal identifiers, or contact details of any kind.
• Behavioral data or usage patterns beyond the specific preference value saved.

Retention

Preference cookies typically persist for up to 12 months from the date they are set or last refreshed. They are renewed automatically if you revisit the Platform within that period and interact with the relevant preference setting.

Can You Opt Out?

Yes. You can clear or disable preference cookies through your browser settings at any time. If you do, your interface preferences will revert to their default values on your next visit. This will not affect your ability to use the Platform's core tools in any way.

In addition to cookies set directly by Transfonic, certain third-party service providers that we use to operate and improve the Platform may also set cookies on your device. These providers are carefully selected and operate under their own privacy and cookie policies.

Why Third-Party Cookies Are Used

Third-party cookies on Transfonic are limited to the operational and analytical providers we rely on to run the Platform effectively. These include:

• Analytics providers that help us understand aggregate Platform usage patterns through privacy-respecting, anonymized data collection.
• Performance monitoring providers that help us detect, diagnose, and resolve technical issues quickly to maintain Platform reliability.

Your Responsibility

Because third-party cookies are set and controlled by external providers, Transfonic does not have direct control over their content, behavior, or retention period. We strongly encourage you to review the privacy and cookie policies of any third-party providers whose services are present on the Platform.

What We Do Not Allow

We do not permit any third-party advertising networks, data brokers, behavioral tracking platforms, or social media companies to set tracking cookies on the Platform. Any third-party provider we work with is contractually prohibited from using data collected through Transfonic for their own commercial purposes.

Many websites use cookies to build detailed profiles of individual users — tracking which pages they visit, what they purchase, and what content they engage with — in order to serve them targeted advertisements across the internet. Transfonic does not participate in this practice.

We do not work with advertising networks, data management platforms, or programmatic advertising services that would require the placement of advertising or tracking cookies on your device. We do not sell, rent, or share cookie data with any advertising third party.

While the Platform may display advertisements through contextual advertising systems, these systems do not rely on behavioral cookies or personal data profiles derived from your browsing activity. Any advertising displayed on the Platform is contextual in nature — based on the content of the page rather than your personal browsing history.

This approach is consistent with our broader commitment to operating a privacy-first platform, and it will not change without explicit disclosure and an update to this policy.

You have full control over the cookies placed on your device. There are several ways to manage, restrict, or delete cookies associated with Transfonic and all other websites you visit.

Through Your Browser

Every modern browser provides built-in controls for managing cookies. You can use these controls to block all cookies, delete existing cookies, allow cookies only from specific sites, or receive a notification each time a cookie is set. Below are the settings paths for the most commonly used browsers:

Important Note on Disabling Cookies

Blocking or deleting all cookies may affect the functionality of the Platform and many other websites you use. In particular, disabling essential cookies will prevent file upload and processing sessions from functioning correctly. We recommend selectively managing non-essential cookies rather than blocking all cookies entirely.

Opt-Out Tools

For analytics cookies set by third-party providers, you may also be able to opt out directly through those providers' own opt-out mechanisms. Where applicable, links to third-party opt-out pages will be documented in any updated version of this policy that lists specific providers.

Clearing Existing Cookies

If you wish to remove all existing cookies set by Transfonic from your device, you can do so through your browser's history or privacy settings by selecting the option to clear cookies and site data. Note that doing so will also reset any preferences you have saved on the Platform.

Some browsers include a "Do Not Track" (DNT) setting that sends a signal to websites requesting that they not track your browsing activity. At present, there is no universally accepted standard for how websites should respond to DNT signals, and no common technical implementation exists across browsers or web services.

Because Transfonic does not engage in cross-site behavioral tracking or advertising profiling regardless of DNT signals, your privacy is protected on our Platform whether or not your browser has DNT enabled. We support the intent behind DNT and are committed to not tracking users across external websites under any circumstances.

We will continue to monitor the development of DNT standards and will update our practices accordingly if a clear, implementable standard emerges and gains broad adoption.

Different types of cookies are retained for different lengths of time, depending on their purpose. The table below summarizes the retention periods for each cookie category used on the Platform:

• Essential cookies — session only. Deleted automatically when you close your browser tab or window.
• Analytics cookies — up to 24 months. Renewed on each visit to the Platform within the retention window.
• Preference cookies — up to 12 months. Renewed each time you interact with the relevant preference setting.
• Third-party cookies — duration varies by provider. Please refer to the relevant provider's own cookie or privacy policy for specific retention details.

You may delete any cookie from your device at any time through your browser settings, regardless of its intended retention period. Cookies that have reached their expiry date are automatically removed by your browser without any action required on your part.

We may update this Cookies Policy from time to time to reflect changes in how we use cookies, changes in applicable laws and regulations, or changes in the third-party services we use. When we make updates, we will revise the "Last Updated" date at the top of this page.

For material changes — particularly those that introduce new categories of cookies or change how we share cookie data — we will make reasonable efforts to provide a prominent notice on the Platform before the changes take effect. We may also re-present a cookies consent notice if our practices change in a way that requires fresh consent.

We encourage you to review this policy periodically to stay informed about how we use cookies. Continued use of the Platform after changes are published constitutes your acceptance of the updated policy. If you do not agree with the updated policy, you should adjust your browser settings to disable non-essential cookies or discontinue use of the Platform.

If you have any questions about this Cookies Policy, about how we use cookies on the Platform, or about how to exercise your privacy rights in relation to cookie data, please contact us using the details below. We aim to respond to all cookie and privacy-related enquiries within 48 hours on business days.
