PageStow is a local-first browser extension for saving browser context and resurfacing related saved links.

Data The Extension Stores

PageStow stores the following data in local extension storage:

• URLs and titles of tabs you choose to save.
• Domains derived from saved URLs.
• Optional notes, projects, tags, reminders, intents, and statuses you enter.
• Saved browser session metadata, including URLs and titles of tabs in a saved window.
• If you enable Bookmark Assist, URLs and titles from newly created browser bookmarks.

Why Chrome Web Store May Show "Web History"

Chrome Web Store may describe saved URLs and tab titles as Web history. PageStow stores URLs and titles for tabs or windows you choose to save, and new bookmarks if you enable optional Bookmark Assist. Review/Triage reads current open tab URLs and titles to display and group them; viewing these tabs does not automatically add them to your saved library.

PageStow does not request the browser history permission, does not read or erase your full Chrome browsing history, does not read page body content, and does not upload saved browsing context in the free local-first MVP.

Data The Extension Does Not Collect

The MVP does not:

• Upload saved tabs, notes, sessions, or browsing context to a server.
• Read your full browsing history.
• Read page body content.
• Request Gmail permissions.
• Use AI services.
• Require an account.
• Sell user data.

Permissions

• storage: saves your archive in chrome.storage.local.
• activeTab: reads the current tab when you use the extension.
• tabs: saves current-window session metadata, reviews open tabs, and restores saved sessions.
• bookmarks: optional. Requested only if you enable Bookmark Assist.

Export And Deletion

You can export your saved archive as JSON from the extension popup. You can delete saved items and sessions in the extension. You can also remove all local extension data by uninstalling the extension or clearing its extension data in your browser.

If a PageStow version offers project bundle export and you choose to use it, the extension creates a local HTML file from the saved items and sessions selected through Review/Triage filters. That file can include saved URLs, titles, notes, projects, tags, reminders, task status, and session links. The export is created locally and is not uploaded by PageStow.

Website Recommendations

The website homepage loads a TIYBAI recommendations banner from banner.tiybai.com. Your browser requests its script and a Chinese or English content fragment, sharing ordinary request information such as your IP address, browser information, and the website origin with that service. The banner links to separate TIYBAI websites. It does not receive your saved PageStow tabs, notes, sessions, or extension storage. This website banner is not embedded in the extension.

Future Paid Features

The current local core workflows are free. If PageStow later adds paid licensing, sync, backup, or semantic retrieval, those features will be additive, opt-in, and documented before use. License systems may process account and payment metadata, but saved URLs, notes, sessions, and browsing context should not be uploaded unless a future sync feature is explicitly enabled by the user.
