Card Chaser collects what it needs to find cards for you and nothing it doesn't. It doesn't sell your information or show ads. If you buy Card Chaser Pro, Stripe takes the payment.

What we collect

• Your account.A name and email and a password (stored only as a salted hash, never in readable form). A guest account has no email, only a random ID.
• What you track.The chases and sets you follow, the cards you mark as owned or spare, graded copies you add (company, grade and cert number, if you enter one), the grade you want for a card or chase, the sets you finish (and any trophies from before the app retired them), the purchases you choose to log, favorite sellers and shops, and settings such as an alert topic.
• A public trade page, on unless you turn it off.Your public trade page, at cardchaser.app/t/your-handle (the address your trade QR code opens). Every account has one from the start, a guest account too, showing only the cards you'd trade and the cards you're hunting, with your first name and a handle made from it (a guest's shows no name). You can turn it off any time in Settings, Your trade page, change the name and handle, and choose which other parts to show (see "Your public trade page" below). It never shows your email.
• Who you follow and block,if you have a public trade page, and the things you did that your public trade page shows as activity, if you let it.
• Prices you choose to share.Only if you say yes (see below).
• Your shipping address, only if you trade by mail.Entered once in Settings, checked with the company that makes our shipping labels, and stored encrypted. The person you trade with never sees it in the app, only your city and state (see "Trade by mail" below).
• Pro, if you buy it.Your plan, when it renews or ends, and Stripe's customer and subscription IDs for your account. Stripe keeps your card and billing details; we never see your card number.
• A shop, if you claim one (a Shop account).Your shop's name, its web address or the stock list you paste, your checkout address, your table and hours at a show, and your Shop membership (when it ends or renews, and Stripe's IDs if you pay). See "Shop accounts" below.
• Holds.When you ask a shop to hold a card, we keep the card, the time, a short code and the shop's answer. The shop sees the card and the code, not your name, handle or email.
• Card scans, if you use Scan cards (Pro).Your photos and videos stay on your phone: the cards are found in them there. Only a picture of each card found is sent, to be read. What was read comes back to your phone for you to check; neither it nor the pictures are stored. We keep a count of how many cards each account scans each day, for the daily limit. Nothing from a video is kept unless you choose to share a highlight (below).
• Highlights, only if you share one.After a video scan you can tick a box to share a short clip (up to about 15 seconds, made on your phone) as a highlight, with an optional caption and your best cards from the scan (see "Highlights" below).
• Card reports.If you tap "Something wrong with this card?", we keep the card, what you picked as wrong and any note you write, so we can fix the card list. Reports don't carry your name, email or account. Don't put personal details in the note.
• Basic technical data.Our hosting provider records things like IP address and device type when you use the site, for security and reliability.
• Price history (not about you).Card Chaser keeps a daily record of TCGplayer's market price for each card, and of the asking prices on public eBay listings it matched to each card. It holds only card prices, nothing about who looked or bought.

We don't collect card details (Stripe does, if you buy Pro), your precise location, your contacts or your photos, except photos you choose to add to a report (see Reports below). Pictures of cards you scan are read and not kept (see Scan cards above). The only video we keep is a highlight you choose to share.

How we use it

To run the service: show your chases and feed, search for the cards you want, send alerts you ask for, and keep the service secure. We search eBay and other sources for cards many people want at once, and those searches are not linked to who is asking.

Your public trade page

Your public trade page lets other collectors see what you collect, trade with you at a show, and follow you. It's at cardchaser.app/t/your-handle, the address your trade QR code opens. It's on from the start for every account, a guest account too, until you turn it off, and it starts with its Trade binder alone, shown to everyone: your handle, your first name (none for a guest, until the account is saved), the cards you'd trade, the cards you're hunting and the names of your chases. An optional line about you, your place and your skin show once you add them, and a public trade page someone turned on before public trade pages were on from the start also shows up to five favorite cards. Every other part is off until you choose who sees it: everyone (anyone who opens your public trade page, signed in or not), only people you follow who follow you back, or nobody.

• The parts:your sets, how far along each is and the badge a finished set wears (silver, gold or platinum); your Trade binder (your note, the cards you're hunting, the cards you'd trade, and the names of your chases); your activity (finishing a set, adding cards to your trade binder, sharing a highlight); and your collection (which cards you have, how many, and the grader and grade of graded cards), which collectors see when they visit your wall in the app.
• A trade page you published before public trade pages had partsbecame your public trade page with only its Trade binder showing, to everyone, as before. Nothing else was shown until you choose.
• Also off unless you turn them on:the day each card became yours, the market value of your collection, and a Pro mark if you're a member. If you show both your collection's value and your place, the app warns you, because together they tell strangers where valuable cards are.
• Never shown to anyone:your email, what you paid for anything, slab cert numbers, your price limits and budgets, your alerts or settings.
• Matches.When someone signed in visits you, Card Chaser works out which of your cards they're chasing (from the parts you show them) and, only if your Trade binder is shown to them, which of their cards you're chasing. They see those matches, never your whole chase list.
• Following and blocking.To follow someone you need a public trade page of your own; they see your handle among their followers. Blocking someone hides you from each other in the app: public trade pages, search, suggestions and activity, both ways. A part you show to everyone can still be seen by anyone who isn't signed in.
• Turning it off.In the app's Settings, Your trade page, switch your public trade page off, or set any part to nobody. Off, no one can open or find your public trade page, and the activity we recorded for it is deleted. Once you turn it off it stays off: we never turn it back on for you. Deleting your account deletes your public trade page, who you follow and block, and your activity.
• Reports.Anyone can report a public trade page. We review reports and can take one down. If you add photos to a report, only you and we can see them; the person you report isn't told who reported them. Photos are deleted 90 days after we close the report, or when you delete your account.

Shop accounts

A card shop or show dealer can claim a shop on their account. Then Card Chaser reads the shop's in-stock singles (from its Shopify store's public product feed, or a list the shop pastes), matches them to what collectors are chasing, and shows a match in a collector's feed with a link to the shop's own website or checkout. The shop has a public storefront page at cardchaser.app/v/their-handle, which anyone can open.

• What a shop sees about collectors: counts, never names.A shop sees how many collectors want cards they have, and each hold's card and code. A shop never sees who is chasing what, a collector's name, handle, email or collection. Collectors see the shop's shop name, table and hours.
• Holds.If you ask a shop to hold a card, the shop is told the card and a short code, and you are told their answer. A hold runs out at the end of the show day, or after 48 hours. Either side can report a hold, and we can end one.
• No money through Card Chaser.Buying happens on the shop's own site or at their table, under the shop's terms. Card Chaser isn't a party to the sale. In-app checkout is planned for 2027 and will come with its own terms.
• What's kept for the shop's bill.Card Chaser counts each month's want-list matches and holds per shop as keyed hashes, so the count is right and no collector is named in it.
• The Shop membershipis free for founding shops until March 31, 2027, then $29 a month through Stripe, which keeps the shop's card and billing details.

Highlights

A highlight is a short clip from a video scan, shared only when you tick "Share as a highlight on my profile". Unticked, the video never leaves your phone.

• What's stored.The clip (made on your phone, at most about 15 seconds and 720p), a still from it, your caption, and the cards it's tagged with. It's stored by Netlify for Card Chaser.
• Who can see it.It follows your public trade page's Activity: everyone (anyone who opens your public trade page, signed in or not), only people you follow who follow you back, or nobody but you. With your public trade page off, only you can. We can see it too, to deal with reports.
• Check it first.A video can catch faces, voices, addresses or other personal details. Watch yours before you share it.
• Sharing on Card Chaser's social pages is a separate choice.Only if you also tick "Card Chaser may share it on its social pages" can we repost the clip, with your handle, on our social accounts. You must be 18 or older, or have a parent's or guardian's permission. You can withdraw that permission anytime, from the highlight or in Settings; we won't post it again after that, and we take down a post we already made.
• A record of what you agreed to.For each choice we keep which clip, the version of the words you saw, when you agreed and when you withdrew. If you delete a highlight, that record stays, with the clip gone. If you delete your account, it goes too, unless we had already posted the clip, when we keep it to show we had your permission.
• Deleting.Delete a highlight in Settings, Your highlights, and the clip and still are removed everywhere we keep them, and both permissions are withdrawn. Deleting your account deletes all your highlights. If a highlight is reported, we can take it down.

Trade by mail

Trade by mail lets two members, both with Card Chaser Pro, send each other cards with tracked labels bought in the app. It isn't open yet. This is how it will handle your information.

• What we keep.Each offer and its versions (the cards, their market values at the time, your note), each answer, your labels (carrier, service, tracking number and cost), the carrier's tracking updates, and when each of you marked your cards sent and received.
• Your address.Only you can see it in the app, and it's stored encrypted. To make a label, we send your address and the other trader's to the company that makes our shipping labels, and the label shows both, as any package does. Until then the other trader sees only your city and state.
• How long.Your address stays until you delete it in Settings or delete your account. A trade keeps the addresses its labels used, encrypted, until 30 days after the trade ends, in case of a dispute, then forgets them. The trade stays in both people's history; if you delete your account, the other person sees "A deleted account".
• Reports.Either side can report a trade. We look at its record to decide what to do. Photos you add (up to three) are seen only by the two of you and us, never shown publicly, and deleted 90 days after we close the report, or when you delete your account. The app makes each one a smaller copy first, without the location or other details your camera saved in it.
• Notices.New offers, answers, shipping and delivery come as phone alerts if you've turned them on.

Prices you choose to share

This is optional and off until you say yes. If you share, then when you log a purchase or finish a trade, Card Chaser keeps the card, the price you paid, the asking price and the market price at the time, where it came from (for example eBay or a shop), whether it was an auction or a fixed price, and, for trades, the cards, conditions and values on each side.

• We do not keep your name or email, the listing link, the seller, or the other person in a trade.
• Each record carries a random code, not your account ID. The code lets us delete your records if you delete your account and count how many different people contributed. It isn't enough, on its own, to tell who you are.
• We combine records into statistics, such as how the prices people pay compare with asking prices, and use them to improve deal scores, market prices and features. We don't sell the records or publish individual ones, and we only show a figure when several records from several people stand behind it.
• Guests can't share prices; you need a saved account. You can turn sharing off in Settings at any time. Statistics already built from your past records stay in the combined numbers.

Who else is involved

• Netlifyhosts the app and stores its data, including the highlights you share.
• Social networks, only for a highlight you let Card Chaser share on its social pages: we repost the clip with your handle on our accounts, and the network's own terms and privacy policy apply to that post.
• Reddit.When the Reddit source is on, we read new posts on public trade subreddits through Reddit's official API and show a post's title, a link back to it and the author's username when it matches a card someone is chasing. Posts are kept for at most 3 days, and posts that are deleted or removed on Reddit are dropped. We only read; we never post or message on Reddit.
• eBay.We use its public listing data. When you click an eBay link, eBay and its partner network may set their own cookies so a purchase can be credited to us.
• Card data and images.Card lists come from two open card databases, tcgdex (cards-database, MIT license) and the Pokémon TCG API's open data, and Card Chaser keeps its own copy. Prices come from TCGplayer (through TCGCSV's daily copy) and Cardmarket figures. Card images load straight from pokemontcg.io, Scrydex and tcgdex, so they can see your IP address.
• PSA, only when you add a PSA-graded card with its cert number: the cert number is sent to PSA's official API to confirm the card and grade, and the card's population report is fetched from PSA. Nothing about you is sent.
• Anthropic, only when you use Scan cards. The picture of each card found in your photos or video is sent to Anthropic's Claude, which reads the card's name, set and number for us. Anthropic processes the pictures on our behalf to give us that answer; we don't send your name, email or account with them, and we don't store the pictures.
• Stripe, only if you buy Pro. It takes the payment and keeps your card and billing details, under its own privacy policy. We send it your email and your account ID so the payment reaches your account.
• Our shipping label provider, only when you trade by mail. It checks your address and makes the labels, so it receives both traders' names and addresses and the package's weight, and processes them on our behalf. The carrier (such as USPS or UPS) gets the label, as for any package.
• Resendsends our email: a welcome when you save an account with an email (with a link to confirm the address), a link to choose a new password when you ask for one, and the weekly email, unless you switch it off in Settings or with the Unsubscribe link in it. It receives your email address and the email's text, and processes them on our behalf.
• ntfy.sh, only if you turn on phone alerts. Alert text passes through it, and anyone who knows your topic name can read it, so keep it private.

Your public trade page is the only thing other users can see of your collection: the cards you'd trade and the cards you're hunting unless you turn it off, and any other part you choose to show on it.

On your device

The app keeps a sign-in token, your filters and an in-progress trade in your browser's local storage. It sets no tracking cookies and uses no advertising or analytics trackers.

A copy of your collection is kept on your phone so the app opens offline. It's removed when you sign out.

Keeping and deleting your data

We keep your information until you delete it. In Settings you can download a backup of your data and delete your account, which removes your account, your shared-price records and everything else stored with it, and cancels a Pro subscription. Stripe keeps its own payment records as the law requires. Accounts that go unused for a long time may be removed.

Your choices

You can access, correct or delete your information from Settings, or by emailing catchem@cardchaser.app. We do not sell personal information, including under California law.

Children

Card Chaser isn't meant for children under 13, and we don't knowingly collect information from them.

Security

We protect passwords with hashing and limit sign-in attempts. No service is perfectly secure, so use a password you don't use elsewhere.

Changes

If this policy changes in a way that matters, we'll update the date above and, for big changes, tell you in the app.
