Section 02
How FormatOS May Use Cookies
FormatOS may use cookies and similar technologies for the following purposes:
- Operating the website and keeping the file conversion interface functional
- Supporting file upload sessions, conversion workflows, and download availability
- Remembering user preferences such as color theme or interface settings
- Improving website speed, performance, and overall reliability
- Detecting technical errors and understanding what causes them
- Understanding which pages, formats, and tools are most useful to visitors
- Protecting the service from spam, abuse, fraud, automated bot traffic, and security threats
- Supporting advertising and monetization if ads are displayed on the site
- Improving the user experience over time based on usage patterns and feedback
Not all of the above may be active at all times. FormatOS uses "may" to reflect that the website is evolving and cookie usage may change as features, analytics, advertising, or security tools are added or updated.
Section 03
Types of Cookies We May Use
Cookies used on or connected to FormatOS may fall into the following categories. Some may be active now; others may be introduced as the website grows.
Essential Cookies
These cookies are needed for core website functionality. They may support page navigation, file conversion sessions, upload workflows, download availability, abuse prevention, security checks, and basic site operations. Without essential cookies or similar site technologies, parts of FormatOS may not work properly.
Performance and Analytics Cookies
These cookies help understand how visitors interact with FormatOS. They may measure page visits, tool usage, errors, load times, device types, browser types, referring pages, and general usage patterns. Analytics data helps improve usability, reliability, and performance. Analytics cookies are used as usage-improvement tools, not for building individual profiles.
Preference Cookies
These cookies may remember choices you make on FormatOS. Examples may include your selected color theme, interface preferences, or convenience settings supported by the website. Preference cookies help provide a smoother and more consistent experience across visits.
Security and Abuse-Prevention Cookies
These cookies or technologies may help detect suspicious activity, bot traffic, spam, abuse, excessive or automated requests, and attempts to disrupt the service. They may support rate limiting, session validation, risk assessment, and general service protection. These technologies help keep FormatOS safer and more reliable for all users.
Advertising Cookies
If FormatOS displays advertising, third-party advertising partners or advertising networks may use cookies, pixels, device identifiers, or similar technologies. These may help serve, personalize, measure, limit frequency of, and improve advertisements. Advertising partners may collect limited technical data such as browser type, device information, IP address, approximate location, pages viewed, and ad interactions. FormatOS does not control every cookie or tracking technology used by third-party advertising systems.
Note: The appearance of advertising on FormatOS does not mean FormatOS endorses the advertiser, product, service, or claim. Advertising does not mean FormatOS sells uploaded files or user documents to advertisers.
Section 04
First-Party and Third-Party Cookies
First-party cookies are set directly by FormatOS for the purposes described in this policy. These may include preference storage, session management, security checks, or basic performance monitoring.
Third-party cookies are set by services that are integrated with or connected to FormatOS. These may include:
- Hosting and infrastructure providers
- Analytics and usage monitoring services
- Security and abuse-detection systems
- Performance and content delivery services
- Advertising and ad measurement partners
- Contact form or communication tools
Third-party services operate under their own terms, privacy policies, and cookie practices. FormatOS does not control all third-party cookies, technologies, or data collection practices. Users should review the privacy and cookie policies of third-party services where relevant.
Section 05
Cookies and File Conversion Activity
Cookies and similar technologies may support the technical operation of file conversion workflows on FormatOS. Specifically, they may help:
- Maintain temporary sessions during file upload and conversion
- Remember your selected output format within a browsing session
- Detect technical errors in the conversion process
- Support the availability of converted file downloads
- Improve interface performance during file processing
- Prevent abuse, automated scraping, or excessive conversion requests
Uploaded files are governed by the Privacy Policy, Terms & Conditions, and File Privacy / Upload Policy. Cookies do not grant FormatOS any ownership rights over files you upload. Advertising cookies do not mean FormatOS sells uploaded files or user documents. You remain responsible for the files you upload and convert through the service.
Section 06
Local Storage and Similar Technologies
FormatOS may use browser local storage, session storage, or similar browser-based technologies in addition to or instead of traditional cookies. Local storage and session storage are built into modern browsers and allow websites to save data directly on your device.
These technologies may be used to store:
- Your color theme preference (light or dark mode)
- Interface settings or layout preferences
- Temporary session or workflow information
- Performance or caching-related settings
Local storage is different from cookies in that it is not automatically transmitted to the server with each request — it remains on your device until cleared. Session storage is cleared automatically when the browser tab or window is closed.
You can clear local storage and session storage through your browser settings under site data or storage controls. Clearing these may cause preference settings such as your selected theme to reset to default.
Section 07
How Long Cookies May Remain
Session cookies
Session cookies are temporary and expire automatically when you close your browser. They may be used to support active conversion sessions, security checks, or temporary interface states.
Persistent cookies
Persistent cookies remain on your device for a defined period after your browser is closed. They may be used for preference storage, analytics, or advertising. The retention period varies depending on the purpose and the service that sets the cookie.
Third-party cookie retention
Third-party cookies are set and controlled by external services. Their retention periods follow the policies of those providers. FormatOS does not control the expiration periods of third-party cookies.
You can remove cookies at any time through your browser settings. Cookie behavior on FormatOS may be updated as the website evolves and new services or features are introduced.
Section 08
Managing or Disabling Cookies
You have control over cookies and similar technologies through your browser and device settings. Options that may be available to you include:
- Adjusting your browser settings to block or restrict certain types of cookies
- Deleting existing cookies stored in your browser
- Using private or incognito browsing mode, which limits persistent cookie storage
- Managing site permissions on a per-site basis through your browser settings
- Adjusting device-level privacy settings where applicable
- Using third-party privacy browser extensions or controls where available
Important: Blocking all cookies may affect the functionality of FormatOS. Essential features such as file upload sessions, conversion workflows, security checks, preference retention, or download availability may not work correctly if certain cookies or site data are disabled. Blocking third-party cookies is less likely to affect core conversion functionality.
For instructions on managing cookies in your specific browser, refer to your browser's help documentation or settings menu. Common browsers include settings under Privacy, Security, or Site Data controls.
Section 09
Advertising Choices
If advertising is displayed on FormatOS, you may have options to manage how advertising-related cookies or technologies are used:
- Browser settings — most modern browsers allow you to block or limit third-party cookies, which may reduce advertising-related data collection.
- Device privacy settings — some devices offer system-level advertising preference controls that may limit ad personalization.
- Third-party privacy opt-out tools — advertising industry organizations may offer tools that allow users in certain regions to limit personalized advertising from participating companies.
- Browser privacy extensions — some browser extensions can limit the data collected by advertising technologies.
Blocking advertising cookies or opting out of personalized advertising does not necessarily remove all ads from the website. It may make the ads you see less relevant to your interests. FormatOS does not control all advertising preference systems used by third-party advertising partners and cannot guarantee the effectiveness of third-party opt-out mechanisms.
For full details on how advertising and cookies may interact on FormatOS, see the Privacy Policy.
Section 10
Do Not Track and Privacy Signals
Some browsers and devices allow users to send "Do Not Track" (DNT) or similar privacy preference signals, such as the Global Privacy Control (GPC), to websites they visit. These signals are intended to communicate that the user prefers not to be tracked across websites for advertising or other purposes.
There is currently no universally accepted or legally mandated standard for how all websites and third-party services must respond to Do Not Track signals. As a result, FormatOS and the third-party services it uses may not respond to every DNT signal in the same way.
Where legally required privacy signals apply and where technically supported, FormatOS aims to respect them in accordance with applicable law. Users can also manage their cookie and site data preferences directly through their browser or device settings, regardless of DNT signals.
Section 11
International Users
FormatOS is accessible to users in multiple countries, including the United States, United Kingdom, European Union, Canada, Australia, India, and other regions. Cookie and privacy rules may vary significantly by location.
Depending on where you are located, you may have additional rights or choices related to cookies, consent, analytics, advertising, or personal data under local privacy laws. This may include rights to access information held about you, request deletion, withdraw consent, or lodge a complaint with a relevant data protection authority.
FormatOS aims to operate with transparency and respect for user privacy regardless of location. If you have questions about your rights or about how cookies are used, you can contact us through the Contact page. See also the Privacy Policy for full details on how personal information and usage data may be handled.
Section 12
Updates to This Cookie Policy
FormatOS may update this Cookie Policy from time to time to reflect changes in the website, the technologies used, applicable laws, analytics tools, advertising systems, or security practices. When changes are made, the "Last updated" date shown at the top of this page will be revised.
Your continued use of FormatOS after an updated Cookie Policy is published constitutes your acceptance of the changes. If you do not agree with the updated policy, you should adjust your cookie settings or stop using the website.
We encourage you to review this page periodically, particularly if you are a regular user of the conversion tools or have questions about how cookies and similar technologies may be used.
