Privacy boundaries for browser-based tools.

1. Browser-first processing

Most focused tools process copied text directly in your browser using JavaScript APIs such as JSON.parse and the Web Crypto API. Your input is not uploaded to a server, stored in a database, or shared with third parties by the tool logic. The site is designed for small snippets and learning/debugging workflows, not for storing or collecting your tool input.

2. Third-party services

Pages may load analytics, advertising, CDN, and verification services. These third parties can receive standard web request information such as your IP address, user agent string, referring URL, and device/browser signals. Currently used services may include:

• Google AdSense: displays advertisements and may use cookies for interest-based advertising. See Google's Privacy Policy.
• Google Analytics (if enabled): collects anonymized page-view and interaction data for site performance analysis.
• Alibaba Cloud OSS & CDN: hosts and delivers static site assets. CDN edge servers may log request metadata.
• Baidu Analytics & Verification (if enabled): provides site verification and analytics for Chinese-language users.

3. Cookies and local storage

This site uses cookies and browser local storage for the following purposes:

• Essential: local storage stores your cookie consent preference and lightweight workspace preferences (recently used tools, favorites). No account or personal data is stored.
• Analytics: analytics services may set cookies to distinguish unique visitors, track page views, and measure performance (Core Web Vitals). These cookies do not contain personally identifiable information.
• Advertising: Google AdSense and its partners may set cookies for frequency capping, ad personalization, and campaign measurement. Users in the EEA, UK, and California are shown a consent banner before advertising cookies are activated.

You can clear all local data from this site through your browser settings at any time. For third-party cookies, see each provider's opt-out instructions.

4. Data retention

Tool input is processed in your browser and is not retained by FreeToolsBox servers. The out/ directory deployed to the CDN is a static HTML/CSS/JS bundle generated at build time — it contains no user data, no database, and no server-side session storage. Analytics and advertising partners retain data according to their own policies. Local storage data (workspace preferences, consent choice) remains on your device until you clear it.

5. Sensitive data warning

Do not enter passwords, private keys, production bearer tokens, personal identification numbers, customer records, medical data, financial records, or confidential company information into any online page. Even though most tools run locally, browser extensions, clipboard managers, and device-level software can read textarea content. This is a safety boundary, not a technical limitation.

6. Your rights

Depending on your jurisdiction, you may have rights under GDPR (EEA/UK), CCPA (California), or other data protection laws. Since FreeToolsBoxdoes not collect, store, or process personal data from the tools, most data-subject requests (access, deletion, portability) are not applicable to the tool layer. For data held by third-party services (advertising partners, analytics providers), please refer to each provider's privacy policy for opt-out and data-subject request procedures.

You may decline non-essential cookies via the consent banner. You may also configure your browser to block third-party cookies, or use browser extensions to control tracking.

7. Children's privacy

FreeToolsBox is a set of developer utilities and technical guides intended for software developers, site operators, and technical professionals. It is not directed at children under 16. We do not knowingly collect personal data from children.

8. Changes to this policy

This privacy policy may be updated as the site and applicable regulations evolve. The date at the top of this page indicates when it was last reviewed. Material changes to how we handle data will be noted on the Updates page.
