Privacy policy
Last updated: 2026-04-25
SusFlag is a Chrome extension that hides eBay listings from sellers whose feedback falls below thresholds you configure. This document explains exactly what data the extension handles.
What we collect
Nothing leaves your browser. SusFlag does not have a server, an API key, or an analytics pipeline.
The extension reads the following on your device only:
- The DOM of
ebay.com(and other eBay TLDs) pages you visit, to find seller feedback numbers. - Your settings — enabled state, filter thresholds, mode — which are stored in Chrome's built-in
storage.syncarea. Sync is a Google service; if you are signed into Chrome, your settings sync across your own Chrome installations. SusFlag does not access or transmit that sync data elsewhere.
What we don't do
- We don't send your eBay browsing or listing data to a SusFlag server.
- We don't use third-party analytics, telemetry, or crash reporting.
- We don't read pages outside eBay — see
host_permissionsinmanifest.json. - We don't log your searches, purchases, or browsing history.
- We don't share data with eBay, advertisers, or anyone else.
Permissions explained
| Permission | Why |
|---|---|
storage | To save your filter settings locally. |
host_permissions on *.ebay.* | So the content script can run on eBay pages and read seller feedback numbers from the page DOM. |
Payment & licensing (when enabled)
If a future SusFlag build enables paid licensing, payment is handled by ExtensionPay (a third party). Their privacy policy applies to payment data. SusFlag itself receives only an entitlement signal — paid or unpaid — used to gate features. No purchase or eBay browsing data is sent to a SusFlag server.
