Privacy Policy

Last updated: 6 April 2026

1. What Data We Collect

BidWatch stores the following data locally in your browser using local storage. No personal data as defined in GDPR Article 4(1) is collected on our servers.

  • Your auction watchlist (eBay item IDs, cached listing data)
  • App settings and preferences (theme, language, sound toggles, etc.)
  • TOS acceptance status and timestamp
  • Price change history for tracked listings (stored locally, up to 50 entries per item)

This data never leaves your device unless you choose to export it using the in-app export feature.

2. What Data Is Sent Externally

When you add or refresh a listing, the eBay item ID is sent to our API server (hosted on Cloudflare Workers) which queries the official eBay Browse API. Your IP address is visible to Cloudflare as part of standard HTTPS requests but is not logged or stored by BidWatch.

Server-side caching: Our server may temporarily cache publicly available eBay listing data (such as titles, prices, bid counts, and images) to improve performance and reduce API usage. This cached data contains no personal or user-identifiable information. Items not actively tracked are removed from the refresh cycle within one hour. Cached listing data in our server may persist for up to 7 days before automatic expiry.

Web Push Notifications: If you turn on push notifications, we store a browser-generated subscription URL and your tracked item IDs on our server so we can send you alerts. This data is removed when you unsubscribe.

We do not collect, store, or log:

  • Personal information such as names, email addresses, or account details
  • IP addresses or browsing history
  • Device fingerprints or identifiers

If you enable push notifications, a browser-generated push endpoint URL is stored on our server for notification delivery only (see Web Push Notifications above). No other personal data is stored server-side.

3. Cookies & Local Storage

BidWatch uses your browser's local storage to save your settings and auction data locally. Under the ePrivacy Directive (2002/58/EC) as implemented by EU member states, local storage used for functionality strictly necessary to provide the service does not require consent.

These include cookies for ad personalisation, frequency capping, and fraud prevention. Under the ePrivacy Directive and GDPR, these advertising cookies require your consent. Google's built-in Consent Management Platform (CMP) will be presented to you on your first visit, offering three choices: Consent (personalised ads), Do not consent (non-personalised ads), or Manage options (granular control). If you do not consent, ads will still be shown but will not be personalised, and only limited cookies for frequency capping and fraud prevention may be set. You can change your consent at any time by clearing your browser cookies.

No third-party analytics services are integrated.
