Privacy

Accounts

OPChase has no user accounts and no log-in. We do not ask for your name, address or payment details.

Analytics

We do not run analytics right now and no analytics script is loaded. If we enable it, we will use GoatCounter, which is cookieless, does not track you across sites and only keeps aggregate statistics (page, referrer, browser type, country). It would also count clicks on links to eBay as anonymous events (page, link position and card, for example ebay/home/bin/OP05-119-MANGA), with no personal data attached. We will update this page when it is turned on.

Listing alert emails

Free email alerts for new verified listings are coming soon and no sign-up is possible yet. Once they are switched on: if you set an alert, we store your email address, the card and the alert you chose (for example a new verified Buy It Now listing at or below a price you pick), and when you signed up and confirmed. We use this only to send the confirmation email and the alert emails. It will be stored in a database on Cloudflare (Workers and D1) and emails will be sent through Resend; both process it for us only. To limit abuse we keep a salted hash of your IP address and of your email address, which changes daily and is deleted after 2 days; we never store the IP address itself. Every email has a one-click link to cancel, and you can ask us to delete your data at any time (see Contact). We do not sell or share your address, add it to other lists, or track opens or clicks in these emails.

Waitlist

OPChase no longer runs a waitlist. If you joined the earlier OPChase Pro waitlist on GitHub, that issue is public and handled under GitHub's own privacy statement; ask us (see Contact) and we will close it. We never collected waitlist email addresses.

eBay listing data

Listings (title, price, photo, time left, link) come from eBay's public active listings through the eBay API and are shown under eBay's API terms. Photos are loaded directly from eBay's servers. Listings are refreshed regularly; anything older than 6 hours is not shown, and ended or removed listings are deleted from our data. Each listing photo carries a small "Photo: eBay listing by <seller>" credit with the seller's public eBay username, linking to the listing; we do not show seller feedback or any other seller details. OPChase does not estimate or suggest prices; prices shown are the sellers' own eBay prices or current bids. Clicking "View on eBay" takes you to eBay, where eBay's privacy notice applies.

Affiliate links

OPChase is a member of the eBay Partner Network, eBay's affiliate program. Links to eBay on this site carry an affiliate tracking ID (our campaign ID plus a placement tag naming the page, link position and card, for example home_bin__OP05x119xMANGA; no personal data), and eBay may set its own cookies when you click through, under eBay's privacy notice. OPChase may earn a commission from qualifying eBay purchases through links on this site. It costs you nothing extra and does not change which listings we show or their order.

Cookies & local storage

OPChase itself sets no cookies. If you switch between the light and dark theme, the choice is saved in your browser's local storage (key opc-theme) on your device only and is never sent to us.

Fonts

The Inter typeface is served from this site (self-hosted). No fonts are loaded from Google Fonts or any other third-party font service.
