Privacy Policy
1. What Data We Collect
BidWatch stores the following data locally in your browser using local storage:
- Your auction watchlist (eBay item IDs, cached listing data)
- App settings and preferences (theme, language, sound toggles, etc.)
- TOS acceptance status and timestamp
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 secure API server (hosted on Cloudflare Workers) which queries the official eBay Browse API to retrieve listing details such as price, bid count, and end time.
We do not collect, store, or log:
- Personal information or account details
- IP addresses or browsing history
- Device fingerprints or identifiers
- Any data beyond the eBay item ID needed to fetch listing information
3. Cookies & Local Storage
BidWatch uses your browser's local storage (similar to cookies) to save your settings and auction data locally. No cookies or local storage are used for tracking or analytics.
No tracking cookies are used. No third-party analytics services are integrated. Your privacy is respected.
4. Third-Party Services
BidWatch uses the following third-party services:
- eBay Browse API: To fetch auction item details. Subject to eBay's API Terms of Use.
- Cloudflare Workers: To securely proxy API requests between your browser and the eBay API. Subject to Cloudflare's Terms of Service.
- Google Fonts: To load web fonts (Plus Jakarta Sans, Archivo Black). Subject to Google's Privacy Policy.
5. Your Rights Under GDPR
BidWatch complies with the General Data Protection Regulation (GDPR) and the UK Data Protection Act 2018. You have the right to:
- Access your data — all data is stored locally in your browser and is fully accessible to you at all times.
- Rectify your data — you can edit your settings and watchlist directly within the app.
- Delete your data — you can clear all BidWatch data by clearing your browser's local storage, or by using the in-app settings.
- Export your data — use the in-app export feature to download a copy of your data as a JSON file.
No account or registration is required to use BidWatch. Since no personal data is stored on our servers, there is no server-side data to request deletion of.
6. Data Retention
All user data is stored locally in your browser. BidWatch does not maintain any server-side database of user data. Data persists in your browser until you clear it manually or clear your browser data.
Use the in-app export feature to back up your data regularly. Clearing browser data will remove all saved information.
7. Children's Privacy
You must be at least 13 years old to use BidWatch. If you are under 18, you should have parental consent. We do not knowingly collect personal information from children under 13.
8. Changes to This Policy
