Simple2FA

Privacy Policy

This page explains how Simple2FA handles data inside the browser. The extension is designed to keep 2FA account data local and to use permissions only for the features the user actively invokes.

Last updated: 2026-04-24

English

Simple2FA stores account secrets, issuers, periods, digits, algorithms, and backup data locally in the browser using `chrome.storage.local` or the browser equivalent. It does not upload, sell, or synchronize your 2FA account data to any remote server.

  • `storage` is used to keep accounts and backup data on your device.
  • `activeTab` and `tabs` are used only when you manually scan the current page for a QR code or open the management window.
  • `host_permissions` are used only to read the visible page content while the user explicitly requests QR scanning.
  • The extension does not contain ads, tracking, analytics, or cross-site data collection.
  • You can remove all stored data by deleting the extension or clearing browser extension storage.

中文

Simple2FA 仅在浏览器本地保存账户密钥、签发者、位数、算法、周期和备份数据，使用 `chrome.storage.local` 或浏览器对应接口进行存储。扩展不会将你的 2FA 数据上传、出售或同步到任何远程服务器。

  • `storage` 仅用于在本机保存账户和备份数据。
  • `activeTab` 和 `tabs` 仅用于用户主动扫描当前页面二维码或打开管理窗口。
  • `host_permissions` 仅在用户主动请求扫码时读取当前网页的可见内容。
  • 扩展不包含广告、跟踪、分析或跨站点数据收集。
  • 你可以通过删除扩展或清除浏览器扩展存储来移除全部本地数据。
This policy describes the current behavior of Simple2FA. If the extension changes its data handling in the future, this page should be updated to match.
