核心承诺：mm设计狗不收集浏览历史、页面内容或个人身份信息，也不出售用户数据。仅处理激活授权所需的最少数据。
1. 我们收集哪些数据
mm设计狗仅收集以下最小化数据，且全部用于核心功能运行：
- 激活码（Activation Code）：您输入的激活码字符串，存储在 Chrome 本地存储（
chrome.storage.local），用于验证授权状态。
- 设备指纹（Device Fingerprint）：通过有限的浏览器和设备信号生成的匿名哈希值。用于将激活码与您的设备绑定，防止一码多用。该哈希值不包含姓名、邮箱或 Mobbin 账户信息。
- 激活状态与到期时间：存储在本地，用于判断扩展是否有效。
2. 数据如何传输
仅在以下情况下，数据会从您的设备发送到我们的服务器：
- 激活验证：当您输入激活码或扩展验证授权状态时，扩展将激活码 + 设备指纹哈希发送到我们的验证服务器（Cloudflare Worker）。服务器存储设备指纹哈希与激活码的绑定关系、激活时间、授权类型和到期时间，并返回验证结果。
3. 我们不做的事
- 不收集您的浏览历史、访问的页面内容或用户行为数据
- 不向第三方广告商或数据经纪商出售任何数据
- 不使用 Cookie 追踪用户
- 不读取您在 Mobbin 上的账户信息或个人资料
- 不把 Mobbin 页面内容传输到我们的服务器
4. 数据存储与安全
本地数据存储在 Chrome 的 chrome.storage.local 中。服务端传输使用 HTTPS 加密。设备指纹哈希及其激活记录存储在 Cloudflare KV 中，仅用于授权验证、防止激活码滥用和处理授权支持。
5. 数据保留
本地数据会在您卸载扩展时由 Chrome 删除；点击"取消激活"会清除扩展的本地激活状态。服务器端的激活码、设备指纹哈希与到期记录会在授权有效期及合理的防滥用、客服处理期限内保留。如需申请删除相关记录，请通过本政策中的邮箱联系我们。
6. 适用范围
本政策仅适用于 mm设计狗 Chrome 扩展程序。扩展在 Mobbin（mobbin.com）页面上运行，但我们与 Mobbin 没有任何关联或合作关系。
7. 未成年人
mm设计狗 不面向 13 岁以下儿童，我们不会有意收集未成年人的任何信息。
8. 政策变更
如本政策发生重大变更，我们将更新本页面顶部的"最后更新"日期。建议您定期查看。

mm设计狗 — Privacy Policy (English)
Core commitment: mm设计狗 does not collect browsing history, page content, or personally identifiable information, and does not sell user data. We process only the minimum data required for license activation.
1. Data We Collect
mm设计狗 collects only the minimal data required for core functionality:
- Activation Code: The license key you enter, stored in
chrome.storage.local to verify your authorization status.
- Device Fingerprint: An anonymous hash generated from a limited set of browser and device signals. It is used to bind a license to a device and does not include your name, email address, or Mobbin account information.
- Activation Status & Expiry Date: Stored locally to determine whether the extension is valid.
2. Data Transmission
Data leaves your device only in these cases:
- License Validation: When you enter an activation code or the extension verifies license status, it sends the activation code + device fingerprint hash to our validation server (Cloudflare Worker). The device fingerprint hash is stored with the activation code, activation time, license type, and expiry date so the server can validate the license.
3. What We Do Not Do
- We do not collect browsing history, page contents, or behavioral analytics
- We do not sell data to advertisers or data brokers
- We do not use cookies for tracking
- We do not read your Mobbin account credentials or profile
- We do not transmit Mobbin page content to our server
4. Data Storage & Security
Local data is stored in Chrome's chrome.storage.local. All server communication uses HTTPS. The device fingerprint hash and its activation record are stored in Cloudflare KV only for license validation, abuse prevention, and license support.
5. Data Retention
Chrome removes local extension data when you uninstall the extension. Clicking "Deactivate" clears the extension's local activation state. Server-side activation codes, device fingerprint hashes, and expiry records are retained for the license term and a reasonable period needed for abuse prevention and customer support. You may request deletion by contacting us at the email below.
6. Scope
This policy applies only to the mm设计狗 Chrome extension. The extension operates on Mobbin (mobbin.com). We have no affiliation or partnership with Mobbin.
7. Children
mm设计狗 is not directed at children under 13. We do not knowingly collect information from minors.
8. Changes to This Policy
If we make significant changes, we will update the "Last updated" date at the top of this page.
