Privacy Policy

Effective date: October 10, 2026

Page Screenshot Pro (“the extension”) captures full-page screenshots, annotates them, exports PDFs and runs on-device OCR. This policy explains what the extension and its licence server handle — in short: your screenshots never leave your device.

1. What stays on your device

  • Screenshots and captures. Everything you capture is processed and stored locally in your browser (browser storage / IndexedDB). Captured images are never uploaded to us or to any third party.
  • OCR. Text recognition runs fully offline using a bundled OCR engine (Tesseract.js) inside your browser. Images used for OCR never leave your device.
  • Editor and clipboard. Annotations happen locally. The clipboard is written to only when you explicitly click a copy action.

2. What we store to manage your licence

  • Install ID. On first run the extension generates a random identifier (UUID). It is stored in your browser (chrome.storage.sync, which roams across your devices under your own Google account, with a local fallback). It is used only as the key for your Pro licence — it contains no personal information.
  • Licence state. Whether Pro is unlocked and which plan you bought is stored locally in your browser.

3. Payments (Waffo)

Payments are processed by Waffo, our merchant of record. Checkout opens Waffo's hosted checkout page in your browser — your card details go directly to Waffo and never touch the extension or our servers. See waffo.ai for Waffo's own privacy policy.

After a successful payment, Waffo notifies our licence server (a Cloudflare Worker), which records: the plan purchased, its status and period, your install ID, and — only to support “restore purchase” — the email address you paid with, mapped to that install ID. No screenshot content, browsing history or page content is ever sent to the licence server.

4. “Restore purchase”

If you reinstall the extension or move to a new computer, you can restore Pro by entering the email you paid with. The server looks up the email → install ID mapping and links your new install ID to the original licence. Restore requests are rate-limited; the server never reveals whether an email has a purchase.

5. Permissions — why the extension asks for them

  • activeTab / scripting — to capture the tab you ask it to; content scripts are injected on demand only.
  • file:/// host access — only for local-file screenshots, and only if you enable “Allow access to file URLs” in Chrome.
  • downloads — to save images and PDFs you export.
  • storage / unlimitedStorage — for settings, licence state and capture history.
  • clipboardWrite — only when you use a copy action.
  • contextMenus — right-click menu entries.
  • notifications — local error alerts only (for example, a capture failure).
  • tabs — to notice when the checkout tab returns, so a completed payment unlocks Pro.
  • offscreen — to stitch images in an invisible document instead of opening a tab.
  • identity / identity.email — to pre-fill the email field on the checkout page. Only the address itself is read; it is not stored by us.

6. What we do NOT do

  • No analytics, no telemetry, no advertising SDKs.
  • We do not sell, rent or share your data with third parties for marketing.
  • The extension makes no network requests of its own except licence checks to our licence server (install ID only) and opening Waffo's hosted checkout.

7. Data retention and deletion

Licence records are kept while your purchase or subscription is active (and as required for tax and accounting records by our payment processor). Uninstalling the extension removes all locally stored data — screenshots, settings and install ID. To delete your licence-server record, contact us at the address below.

8. Changes

If this policy changes materially, we will update the effective date above and note the change in the extension's release notes.

隐私政策（中文版）

生效日期：2026 年 10 月 10 日

Page Screenshot Pro（“本扩展”）用于整页截图、标注、导出 PDF 和本机 OCR。本政策说明扩展及其授权服务器处理哪些数据——一句话概括：你的截图永远不会离开你的设备。

1. 只保存在你设备上的数据

  • 截图。所有截图都在浏览器本地处理和保存（浏览器存储 / IndexedDB），绝不上传给我们或任何第三方。
  • OCR。文字识别完全离线运行（内置 Tesseract.js 引擎），图片不离开设备。
  • 编辑器与剪贴板。标注在本地完成；只有当你主动点击复制时才会写入剪贴板。

2. 为管理授权而存储的数据

  • 安装 ID。首次运行时生成随机标识（UUID），存于浏览器（chrome.storage.sync，随你的 Google 账号在设备间漫游，另有本地兜底）。它仅用作 Pro 授权的 key，不含任何个人信息。
  • 授权状态。Pro 是否解锁、购买的套餐，存于浏览器本地。

3. 支付（Waffo）

支付由 Waffo（merchant of record）处理。结账会在浏览器打开 Waffo 的托管收银台页面——银行卡信息直接交给 Waffo，不经过扩展或我们的服务器。Waffo 自己的隐私政策见 waffo.ai。

支付成功后，Waffo 会通知我们的授权服务器（一台 Cloudflare Worker），服务器记录：购买的套餐、状态与周期、你的安装 ID，以及——仅用于“恢复购买”——你付款时用的邮箱（映射到该安装 ID）。截图内容、浏览历史、页面内容永远不会发往授权服务器。

4. “恢复购买”

重装扩展或换电脑后，可输入付款邮箱恢复 Pro。服务器查找“邮箱 → 安装 ID”映射，把新安装 ID 关联到原授权。恢复接口有限流；服务器不会透露某个邮箱是否有购买记录。

5. 权限说明

  • activeTab / scripting — 截取你指定的标签页；内容脚本仅在触发时按需注入。
  • file:/// — 仅用于本地文件截图，且需你在 Chrome 中开启“允许访问文件网址”。
  • downloads — 保存你导出的图片和 PDF。
  • storage / unlimitedStorage — 设置、授权状态、截图历史。
  • clipboardWrite — 仅在你使用复制功能时。
  • contextMenus — 右键菜单项。
  • notifications — 仅本地错误提醒（如截图失败）。
  • tabs — 识别收银台标签页返回，让已完成的支付能解锁 Pro。
  • offscreen — 在不可见文档里完成拼接，而不是多开一个标签页。
  • identity / identity.email — 预填收银台的邮箱框。只读取邮箱本身，我们不存储它。

6. 我们不做的事

  • 无统计、无埋点、无广告 SDK。
  • 不出售、出租或为营销目的与第三方共享你的数据。
  • 扩展自身除向授权服务器查询授权（仅发送安装 ID）和打开 Waffo 收银台外，不发起其他网络请求。

7. 数据保留与删除

授权记录在购买或订阅有效期内保留（支付处理商依法要求的税务与账务记录除外）。卸载扩展会清除所有本地数据（截图、设置、安装 ID）。如需删除授权服务器上的记录，请通过下方联系方式联系我们。

8. 政策变更

本政策有实质变更时，我们会更新上方生效日期，并在扩展更新日志中说明。
