ProductStalker — Privacy Policy
Last updated June 17, 2026
What it collects
For products you track: the URL, title, price, price history, an image URL, your target price, and notes. Your Google account email and name only if you enable sync. Firebase sign-in tokens, stored locally. Product details are scraped only from pages you explicitly track.
Who receives data
A developer-operated price service receives the product URL you track to fetch its price, and forwards a portion of the page's HTML to a third-party LLM provider (OpenRouter) to extract the price. Google Firebase receives your tracked items and account email only when you enable sync. No analytics or ad trackers; data is not sold.
Storage
Tracked products and auth tokens are stored locally with chrome.storage.local. If sync is enabled, tracked products are also stored in Firebase under your account.
Your control
Sync is optional — without signing in, all data stays on your device. Remove items, sign out to clear tokens, or uninstall to delete local data. To remove synced data, delete the items from dash.sivori.xyz.
