CardHawk is made by Tyler Lake Consulting. This policy explains what the app does with your information. The short version: the app works without an account; if you create one, your collection, hunt list, buys and price corrections are stored on our server so they follow you between devices. We run no analytics, no advertising and no tracking.
Without an account, none of this leaves your iPhone.
Account data is hosted for us by Supabase on servers in the United States, protected so that each account can read and write only its own rows. Passwords are hashed by the authentication service; we never see them.
With "Help improve" on, when a lot ends while you are scouting, the app records the closing price Whatnot shows on screen together with the card it was showing, the seller's public handle and the time. It does not record the winner's name, your bids, your account or your device. These prices are pooled across CardHawk users to show what a card has actually closed for on Whatnot, seller statistics, and your own scorecard. Turn "Help improve" off and nothing more is sent.
No analytics, no advertising identifiers, no tracking across apps or sites, no location, no contacts, no photos beyond the ones you deliberately take inside the app (which stay on your device). We cannot see what streams you watch.
When you start the watcher, iOS screen recording sends the screen to CardHawk so it can read card names, numbers and prices. This happens entirely on your iPhone. Nothing from your screen is uploaded, recorded to a file we can read, or shared. Recording runs only while you start it, and the status bar shows it is on.
While a broadcast runs, CardHawk can also hear the stream: the audio of the app you are watching is transcribed on your phone by Apple's on-device speech recognition, so CardHawk can pick up what the seller says about the card (reverse holo, first edition, PSA 9, lightly played, Japanese, the card's name and number) and price it accordingly. The audio and the words stay on the device, are kept for seconds, and are never recorded, stored or sent to us. The microphone is not used. Switch it off any time in Settings under Listen to the stream.
When you accept CardHawk's purchase terms, the app sends us a record of it: a random install identifier, the terms version and a fingerprint of the exact wording, the app version, your device model and iOS version, the time, and the network address it came from. If you are signed in, the record also carries your account id and email, confirmed by our sign-in service. We keep these records permanently, including after an account is deleted, because they are our record that the terms were accepted. They are used for nothing else.
CardHawk gets more accurate by learning from real cards on real streams. Help improve CardHawk is explained when you first open the app and is on unless you switch it off, there or at any time in Settings. While it is on, CardHawk may send us, over Wi-Fi only:
We use this only to find and fix recognition mistakes and to train the card recogniser. Nothing else is sent: not your full screen, the chat, usernames, your bids, your collection or your account. None of it is linked to your account, email or device. Turn it off and anything not yet sent is deleted from your phone. Ask us at support@getcardhawk.com and we will delete records already received, though because they are not linked to you we may not be able to tell which were yours.
Photos you take to check a card's condition are analysed on your device and kept on your device. They are not uploaded.
Subscriptions are handled by Apple. We never see your payment details. Apple tells the app only whether a subscription is active.
CardHawk is not directed at children under 13, and we do not knowingly collect personal information from them.
Open Account in the app and tap Delete account. That permanently removes your account and everything stored against it on our server. Deleting the app removes everything stored on the device. You can also email support@getcardhawk.com and we will delete it for you.
If this policy changes we will update this page and the date above.
