Privacy Policy

Last Updated: April 24, 2026

Core Commitment: All file processing on ZhiMaSpace Tools is performed locally in your browser. Your files are never uploaded to our servers — we cannot access, view, or store any of your file content.

1. Overview

ZhiMaSpace Tools (hereinafter "the Site", URL: tools.zhimaspace.com) is a free online toolset offering PDF processing, image editing, document conversion, OFD invoice handling, and more. We take your privacy seriously. This Privacy Policy explains how we collect, use, and protect your information when you use our services.

2. Local Processing Principle

The core design principle of this Site is "local first". This means:

  • All files you upload (PDFs, images, documents, OFD files, etc.) are processed locally in your browser and are never transmitted to any remote server.
  • Temporary data generated during file processing exists only in browser memory and is cleared when you close or refresh the page.
  • AI features (such as background removal and watermark removal) download model files to run locally in your browser — all inference is performed on your device.
  • OCR text recognition downloads language packs locally, and the recognition process runs entirely in your browser without sending images to external services.

3. Information We Collect

3.1 Automatically Collected Information (via Google Analytics)

This Site uses Google Analytics to understand website usage and improve our services. Google Analytics may collect the following anonymous information:

  • Page views and session duration
  • Traffic sources (search engines, direct visits, referral links, etc.)
  • Device type, operating system, and browser information
  • Approximate geographic location (country/region level, not precise location)
  • Tool pages and features used

3.2 Advertising Information (via Google AdSense)

This Site uses Google AdSense to display advertisements in order to maintain our free services. Google AdSense and its partners may collect and use the following information to serve personalized ads:

  • Cookies and similar technologies (such as web beacons and pixel tags) to identify your browser and device.
  • Your browsing activity on this Site and other websites to infer your interests.
  • Device identifiers, IP address, and approximate geographic location.
  • Ad impression, click, and interaction data.

Google uses this information to show ads relevant to your interests. You can visit Google Ads Settings to manage your personalized ad preferences or opt out. For more information, see Google Advertising Technologies Policy.

Data collection and processing by the above Google services is governed by the Google Privacy Policy.

3.3 Locally Stored Data

This Site uses browser localStorage to store the following preferences. This data is saved only on your device and is never transmitted to any server:

  • Language preference (lang, lang-set): Remembers your chosen interface language.
  • Theme preference (theme): Remembers your light/dark theme choice.
  • Recently used tools (recentTools): Records your recently used tools for quick access.

4. Information We Do Not Collect

For clarity, we never collect the following:

  • Any file content you upload or process (PDFs, images, documents, etc.)
  • Your name, email, phone number, or other personally identifiable information
  • Account credentials or login information (no registration or login is required)
  • Payment information (all features are completely free)

5. Cookies and Tracking Technologies

This Site uses cookies and similar tracking technologies through third-party services, including:

  • Google Analytics Cookies: Used to distinguish visitors and sessions, collecting anonymous website usage statistics.
  • Google AdSense Cookies: Used to serve ads, measure ad performance, and deliver personalized ads based on your interests. Google and its advertising partners may set cookies in your browser for these purposes.

You can manage cookies and tracking in the following ways:

This Site also uses localStorage to save your preferences. localStorage is not a cookie — data is stored only in your browser and is never sent to any server with HTTP requests. You can clear this data at any time through your browser's developer tools.

6. Third-Party Services

This Site uses the following third-party services:

  • Google Analytics: For website traffic analysis. See the Google Privacy Policy.
  • Google AdSense: For displaying advertisements. Google and its certified ad partners may use cookies to serve ads based on your prior visits to this Site or other websites. See Google Advertising Technologies Policy and Google's Certified Ad Partners.
  • CDN Resources: Some pages may load fonts or icon resources from CDN providers, whose servers may log access requests.

Apart from the services listed above, we do not share your data with any third parties.

7. Data Security

Because this Site uses a local processing architecture, the security of your file data primarily depends on the security of your own device. We ensure the security of the website itself through the following measures:

  • The website is served over HTTPS to prevent man-in-the-middle attacks.
  • All file processing logic runs within the browser sandbox, isolated from other websites and your system.
  • No user files are stored on our servers, fundamentally eliminating the risk of server-side data breaches.

8. Children's Privacy

This Site is not directed at children under the age of 13, and we do not knowingly collect personal information from children. Since no registration is required and no personally identifiable information is collected, there is no risk of collecting children's personal data.

9. Your Rights

You have the following rights:

  • Clear local data: You can clear localStorage preference data at any time through your browser settings.
  • Opt out of analytics: You can install the Google Analytics Opt-out Add-on or use your browser's "Do Not Track" feature.

  • Disable cookies: You can disable third-party cookies through your browser settings.
