隐私政策

最后更新:2025年6月13日

我们的隐私承诺

在Image DPI Checker & Converter,我们致力于保护您的隐私。我们的DPI转换器和图像DPI更改工具均以隐私优先原则设计,确保您的图像和个人数据始终安全。

本地处理保证

您的图像永远不会离开您的设备。我们的DPI检查器和300 DPI转换器在您的浏览器中本地处理所有图像。无需上传,无需服务器存储,无需数据传输。您的隐私得到100%保护。

  • All DPI conversion happens locally in your browser
  • Your images are never uploaded to our servers
  • No image data transmission occurs during processing
  • Complete control over your image files at all times
  • Zero risk of server breaches affecting your images

我们不收集的信息

由于我们的图像DPI工具在本地处理所有内容,因此我们不会收集以下信息:

  • Your uploaded images or files
  • Image metadata or DPI information
  • File names or content
  • Conversion history or preferences
  • Personal identification information from image processing

我们收集的信息

我们仅收集最少的、匿名数据,以改进我们的服务:

  • Page views and general usage statistics
  • Browser type and version (anonymous)
  • Device type (desktop/mobile) - anonymous
  • General geographic location (country level only)
  • Error logs for service improvement
  • Performance metrics

我们的DPI工具如何工作

我们的DPI增强器和图像DPI更改器完全在您的浏览器中使用JavaScript运行:

  • You select images from your device
  • Our DPI checker analyzes the image metadata locally
  • When you change DPI of image, processing happens in your browser
  • Download links are generated locally - no server involvement
  • Your original and converted images remain on your device only

Cookies和本地存储

我们使用最少的Cookies和本地存储来实现:

  • Remembering your DPI converter preferences
  • Website functionality and user experience
  • Anonymous analytics (Google Analytics with IP anonymization)
  • No image data or personal information stored in cookies

您可以通过浏览器设置控制或删除Cookies,而不会影响图像处理功能。

第三方服务

我们使用以下第三方服务:

  • Google Analytics for anonymous website usage statistics (IP addresses anonymized)
  • Content Delivery Networks (CDN) for faster website loading - only serve website assets, never your images
  • No third-party image processing services - everything happens locally

数据安全

由于您的图像在本地处理且从不上传:

  • No risk of server breaches affecting your images
  • No data transmission vulnerabilities
  • Complete control over your image data
  • No server-side storage means no data retention risks
  • HTTPS encryption for website browsing

儿童隐私

我们的DPI转换器工具对所有年龄段的用户都安全。由于我们不收集个人信息或存储图像,因此儿童使用我们的图像DPI更改器时不存在特殊的隐私顾虑。

  • No image uploads means no privacy risks for any age group
  • Local processing ensures complete data control
  • No personal information collection from any users

您的权利和选择

您完全掌控您的数据:

  • All image processing happens on your device
  • You can clear browser data to remove any stored preferences
  • You can disable cookies in your browser settings
  • You can opt out of analytics using browser extensions
  • No need to request data deletion since we don't store your images

国际用户

我们的本地处理方式意味着您的图像数据永远不会跨越国界。无论您身在美国、欧盟还是其他任何地方在线检查图像分辨率,您的数据都将留在您的设备上,处于您的司法管辖范围内。

本政策的变更

我们可能会不时更新本隐私政策。任何变更都将在此页面上发布,并附上更新的修订日期。鉴于我们的本地处理方式,大多数变更将是细微的澄清,而非重大的政策调整。
