Privacy Policy (HOC)

House of Collectors · Last updated 10 November 2026

House of Collectors ("the app", "we", "us") helps you scan, price and keep track of your trading cards. This policy explains what information the app uses, why, who else handles it, and the choices you have. We have tried to say it plainly.

The app is run by SaberTheory B.V., Harregatplein 23c, 3214 VP Zuidland, the Netherlands. You can reach us about anything in this policy at houseofdisplays@outlook.com.

The short version

• We keep your collection (the cards you add, their quantities, binders, price alerts and gradings) so it is there when you open the app.
• The pictures you scan are sent to our server to be read, and are not kept. The one exception is optional and off until you say yes (see "Help train our grading").
• We do not sell your information, and we do not show ads or track you across other apps or websites.
• You can delete your account and everything in it from inside the app (Profile, then Delete account).

What we collect and why

Account details: You sign in through our sign-in provider (Clerk) with an email code, Google or Apple. We receive a user identifier from it, and your email address may be held by the provider. We use it to recognise you and keep your collection separate from everyone else's.

Your collection: The cards you add, quantities, notes, binders, price alerts, gradings and the plan you are on. We use it to provide the app: show your collection and its value, send price alerts, and apply the right limits for your plan.

Pictures you scan or choose: Photos from the camera or photo library (a single card, many cards, or screenshots you pick to import a collection), and the cut-out card pictures the live scanner sends. We use them to read the card (name, number, set, grading label) and match it to our catalogue. They are held in memory while the request is processed and are not stored.

Live scanner: While it runs, a cut-out of the card on screen, text read from it on your phone, and an identifier of your device. If you allow speech recognition, the words recognised from the stream's sound are processed on your phone and only the recognised words are sent. We use this to show the card's price. The sound itself never leaves your phone.

Usage counts: How many scans, live minutes, screenshots and gradings you have used in a period. We use them to apply the limits of your plan and to prevent abuse.

Purchase status: Whether you have a subscription, which plan, and when it renews. We never see your card or Apple ID payment details. We use it to unlock the plan you bought. Payments are handled by Apple.

Technical logs: Your IP address, the time of a request and error information. We use them to keep the service secure and working. Photos and request contents are not written to the logs.

Help train our grading (optional)

When you grade a card, your original photos are not kept. If you choose "Help train our grading" in your profile, we also keep the straightened picture of the card and any corrections you made, to improve our own grading model. It is off until you turn it on, and you can turn it off at any time; deleting your account removes what is linked to it.

Who else handles your information

We use a small number of service providers to run the app. They only receive what they need for their job, and they may only use it for that.

• Clerk – sign-in and account security.
• Our hosting and database providers – where the app's server and your collection are stored. Your data is protected so that one account cannot read another's.
• Anthropic – an AI service that reads the pictures you scan. The picture is sent for that request only.
• Ximilar – a card-grading service that receives the front and back photos when you grade a card.
• RevenueCat – manages subscriptions on our behalf, together with Apple, which processes payments.

Card names, pictures of cards and market prices shown in the app come from public catalogues and price sources; that is not information about you.

We do not sell personal information, and we do not share it for advertising. We may disclose information if the law requires it.

Where your information is processed

Some of these providers are located outside the European Economic Area, including in the United States. When personal data is transferred there, we rely on the safeguards the law provides for, such as the European Commission's standard contractual clauses or the provider's participation in the EU–US Data Privacy Framework.

How long we keep it

• Your collection and account data: until you delete your account.
• Scanned pictures: not kept after they are read.
• Technical logs: for a short period (up to 30 days) for security and fixing problems.
• Subscription records: as long as needed for accounting and legal duties.

Your choices and rights

• Delete your account in the app: Profile, then Delete account. This permanently deletes your collection, binders, alerts, gradings and plan, and removes your sign-in. A paid subscription is not cancelled automatically: cancel it in your iPhone's Settings, under your Apple ID, then Subscriptions.
• Camera, photos and speech: you decide whether to allow each in your iPhone's Settings and can change that at any time. Scanning needs the camera or a photo you pick.
• If you are in the EEA, the UK or a similar region, you have the right to ask for access to your information, to correct it, to have it deleted, to restrict or object to how it is used, and to receive a copy. Write to houseofdisplays@outlook.com. You also have the right to complain to your data protection authority (in the Netherlands, the Autoriteit Persoonsgegevens).

Our legal bases are: providing the service you asked for (your collection, scans and subscription), our legitimate interest in keeping it secure and preventing abuse, and your consent where we ask for it (grading training, speech recognition).

Security

Connections to our server are encrypted. Each account's data is separated at the database level, sign-in is handled by a specialist provider, and access to our systems is protected. No system is perfectly secure, but we take care to protect your information.

Children

The app is not directed at children under 16, and we do not knowingly collect information from them. If you believe a child has given us information, contact us and we will delete it.

Changes to this policy

If we change how we handle information, we will update this page and the date at the top, and tell you in the app if the change is significant.
