Privacy Policy

Last updated: March 30, 2026

FastTool ("we," "us," or "our") operates the website located at fasttool.app. We are committed to protecting your privacy and being transparent about how our site works. This Privacy Policy explains what information is collected when you visit FastTool, how that information is used, and what choices you have.

By using FastTool, you agree to the practices described in this policy. If you do not agree, please discontinue use of the site.

1. Information We Collect

FastTool is designed to collect as little personal information as possible. We do not require you to create an account, provide an email address, or share any personal details to use our tools. Here is a breakdown of the types of information that may be collected:

1.1 Information You Provide

When you use our tools, you may enter text, upload files, or paste data into input fields. This information is processed entirely within your browser using client-side JavaScript. We do not transmit your tool inputs to any server. Your data stays on your device and is never stored, logged, or shared by us.

1.2 Automatically Collected Information

Like most websites, certain technical information may be collected automatically when you visit FastTool:

  • IP address (collected by our hosting provider, Cloudflare, for security and performance purposes)
  • Browser type and version
  • Operating system
  • Referring URL (the page that linked you to our site)
  • Pages visited and time spent on each page
  • Device type (desktop, mobile, tablet)

This data is collected through server logs and analytics tools and is used in aggregate form to understand site traffic, improve performance, and identify technical issues. We do not use this data to identify individual users.

2. Cookies and Tracking Technologies

FastTool uses a minimal number of cookies and local storage entries:

2.1 Essential Cookies

  • Theme preference (stored in localStorage as "theme") — remembers whether you prefer light or dark mode.
  • Language preference (stored in localStorage as "um_lang") — remembers your selected language across visits.
  • Tool usage history (stored in localStorage) — keeps a local record of recently used tools for your convenience. This data never leaves your browser.

2.2 Third-Party Cookies

We use the following third-party services that may set their own cookies:

  • Google AdSense (publisher ID: ca-pub-7772638845090771) — Google and its advertising partners may use cookies, web beacons, and IP addresses to serve personalized or non-personalized ads based on your browsing history. Third-party vendors, including Google, may place and read cookies on your browser, or use web beacons to collect information as a result of ad serving on this website. To learn more about how Google uses data when you use our site, please visit How Google uses information from sites or apps that use our services. You can opt out of personalized advertising by visiting Google Ads Settings or www.aboutads.info.
  • Cloudflare Web Analytics — Cloudflare collects anonymized analytics data to help us understand site performance and visitor patterns. Cloudflare's analytics are privacy-focused and do not use cookies for tracking. More information is available in Cloudflare's Privacy Policy.

3. How We Use Information

The limited information we collect is used for the following purposes:

  • To deliver and maintain the website and its tools
  • To understand aggregate usage patterns and improve the site
  • To display advertisements through Google AdSense
  • To protect against abuse, spam, and security threats
  • To respond to inquiries sent to our contact email

We do not sell, rent, or trade any personal information to third parties. We do not build user profiles or track individual behavior across sessions.

4. Third-Party Services

FastTool relies on a small number of third-party services to operate. Each of these services has its own privacy policy, and we encourage you to review them:

We do not use any other third-party analytics, marketing, or tracking services beyond those listed above.

5. Data Retention

Since we do not collect personal data through our tools, there is nothing for us to retain or delete on our end. Any data you enter into a tool exists only in your browser's memory during your session and is discarded when you close the tab or navigate away.

Preferences stored in your browser's localStorage (theme, language, tool history) persist until you clear your browser data. You can clear this data at any time through your browser settings.

Server logs maintained by Cloudflare are retained according to Cloudflare's data retention policies, typically for a limited period, and are used solely for security and performance monitoring.

6. Your Rights

Depending on your jurisdiction, you may have certain rights regarding your personal data, including:

  • Right to access — You can request information about what data we hold about you (which is minimal to none).
  • Right to deletion — You can request deletion of any personal data we may hold. Since we do not collect personal data through our tools, this primarily applies to any correspondence you send us via email.
  • Right to opt out — You can opt out of personalized advertising through Google Ads Settings or by using browser extensions that block tracking cookies.
  • Right to lodge a complaint — You have the right to lodge a complaint with your local data protection authority.

To exercise any of these rights, please contact us at the email address below.

7. Children's Privacy (COPPA Compliance)

FastTool is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided personal information to us, please contact us immediately, and we will take steps to remove that information.

Our tools are general-purpose utilities intended for a broad audience, and we encourage parents and guardians to monitor their children's internet usage and to help enforce this policy.

8. International Users

FastTool is accessible worldwide and supports 21 languages. Regardless of where you access the site from, the same privacy protections apply. Since tool processing happens locally in your browser, your data does not cross any borders through our service.

If you are located in the European Economic Area (EEA), United Kingdom, or other regions with data protection laws, please note that our hosting provider (Cloudflare) may process limited server log data in various locations. Cloudflare maintains appropriate safeguards for international data transfers.

9. Security

We take reasonable measures to protect the integrity of our website. Our site is served over HTTPS, ensuring that your connection to FastTool is encrypted. Since we process data client-side and do not maintain user databases, the risk of data breaches through our service is minimal.

However, no method of transmission over the Internet is 100% secure, and we cannot guarantee absolute security. We encourage you to use up-to-date browsers and exercise caution when using any online service.

10. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in our practices, technology, or legal requirements. When we make changes, we will update the "Last updated" date at the top of this page. We encourage you to review this page periodically.

Continued use of FastTool after any changes constitutes your acceptance of the updated policy.
