Privacy Policy — Web2PPT

Last updated: March 22, 2026

Overview

Web2PPT is a Chrome browser extension that converts web pages into editable PowerPoint (.pptx) files. This Privacy Policy explains what data the extension accesses, how it is processed, and what happens to it.

Short version:

Page content (text, layout, images used in the export) is processed locally in your browser to build the .pptx. We do not receive a copy of your pages or your files on our servers for that conversion — there is no Web2PPT backend involved in the export itself.
Optional usage statistics help the developer understand how often the extension is used. These statistics use a one-way hash of the site hostname (e.g. example.com → irreversible digest), not the full URL, path, or page content. You can disable this in storage (see §5). If you configure a remote endpoint (developer-side), only these minimal events may be sent — never the page body.

1. Data We Do NOT Collect

Web2PPT does not collect, store, transmit, or share any of the following for third-party advertising or profiling:

The text or HTML body of pages you export (beyond what your browser must read locally to build the file)
Full page URLs or query strings sent to us (we do not log “which article” you exported)
Authentication tokens, cookies, or session data transmitted to us
The binary content of generated .pptx files sent to us

There is no user account system in the extension.

2. How Web2PPT Works — Local Export

When you click Extract Asset Board (or equivalent):

DOM extraction: A content script reads the visible structure of the active tab (positions, styles, text) using standard browser APIs.
Image fetching: Images may be fetched by the background service worker directly from their hosts (CDNs, etc.) to embed them as data in the .pptx. No Web2PPT server sits in the middle.
PPTX generation: The .pptx is built in memory (e.g. via PptxGenJS) in the extension context.
Download: The file is saved like any other download to your device.

3. Permissions Explained

Permission	Why it is needed
`activeTab`	Access the tab when you activate the extension.
`scripting`	Inject the content script into the active page.
`storage`	Store aggregated usage counters locally and your telemetry opt-out preference.
`<all_urls>` (host permission)	Fetch cross-origin images for embedding; optional HTTPS POST to a single analytics endpoint configured by the developer (if enabled in `background.js`).

4. Third-Party Libraries

PptxGenJS (MIT) — runs locally for .pptx generation; does not phone home.

5. Usage Statistics & Telemetry (Optional)

What is recorded (locally in chrome.storage.local):

Counts of export button clicks, successful exports, and failed exports (global and per calendar day).
For successful exports only: counts keyed by SHA-256 hash of the hostname (e.g. www.example.com → fixed-length hex digest). The hostname itself is not stored in plaintext in that aggregate structure.

What may be sent remotely (only if the developer sets TELEMETRY_INGEST_URL in background.js):

A small JSON payload: event name (export_click, export_success, export_fail), extension version, optional host hash, optional short error code (no stack trace, no URL), timestamp.

What is never sent:

Full URLs, paths, query strings, page titles, HTML, or image payloads.

Opt-out: Set telemetryOptOut to true in chrome.storage.local (e.g. via a future settings UI, or manually in DevTools for advanced users). When opt-out is set, no counters are updated and no remote calls are made.

If no ingest URL is configured, nothing is sent over the network for telemetry — only local aggregates exist.

6. Enterprise & Corporate Use

Export content stays on the device except for normal image fetches to original hosts (same as loading a web page).
No sign-in required for core functionality.
Telemetry is documented above and can be disabled.

7. Children’s Privacy

Web2PPT is a professional productivity tool not directed at children under 13.
