Effective November 13, 2026

Privacy Policy

AuctionDog is designed to work without an AuctionDog account. Personal watch rules and alert history are kept in the user’s Chrome profile whenever possible.

AuctionDog does not sell personal information and does not use personal information for advertising.

Information stored locally by the extension

The Chrome extension stores the following in chrome.storage.local:

Saved keywords, exclusions, price limits and listing-format preferences.
Extension settings and notification preferences.
Recently seen eBay item IDs, used to prevent duplicate alerts.
A limited recent-alert history.
An optional Discord webhook URL, if the user chooses Discord alerts.

This information remains in the user’s Chrome profile. Chrome removes it when the extension is uninstalled unless browser-sync or backup behavior outside AuctionDog preserves it.

Information sent when checking listings

In normal live-stream mode, the extension downloads a shared recent-listing feed and performs each user’s keyword and price matching locally. Personal watch rules are not sent to AuctionDog in that mode.

When a newly created watch is seeded through direct-search mode, its search terms, price range, listing format and category may be sent to AuctionDog’s Cloudflare Worker, which requests matching public listing information from eBay’s official API.

Discord alerts

If a user provides a Discord webhook URL, the extension sends matched-listing details directly from the browser to Discord. AuctionDog does not store the webhook URL on its servers. Discord’s own privacy terms govern that delivery.

Public eBay listing data

AuctionDog temporarily archives normalized public listing information such as item ID, title, price, shipping, condition, listing type, image URL, item URL and creation time. Raw archive batches automatically expire after seven days.

The R2 archive intentionally excludes seller usernames and seller-feedback percentages. AuctionDog maintains an eBay Marketplace Account Deletion endpoint for legacy records and compliance notifications.

Cloudflare processing

AuctionDog uses Cloudflare Workers, R2, caching and static hosting. Cloudflare may process standard request information such as IP address, user agent, timestamps and diagnostic logs as part of providing and securing those services. AuctionDog does not build user profiles from this information.

Website data

This static website does not currently use advertising cookies, behavioral analytics, account registration or a contact form. Standard hosting logs may still be processed by Cloudflare.

eBay links and affiliate attribution

If AuctionDog receives written eBay Partner Network approval, deliberately clicked eBay links may include affiliate attribution. This does not change the buyer’s price. See the Affiliate Disclosure.

Data deletion and user controls

Users can delete watches and alert history from the extension or uninstall the extension to remove its local data. For support or privacy questions, use the method on the Support page.

Children

AuctionDog is not directed to children under 13 and does not knowingly collect personal information from children.

Changes

Material changes will be posted on this page with a revised effective date.
