Masterys

Privacy Policy

Last updated May 21, 2026

This Privacy Policy explains what information Masterys (“we”, “us”) collects when you use the app, how we use it, and the choices you have. It applies to the Masterys mobile app and website.

Information we collect

We collect the information you provide to create an account (such as your name and email address) and the data you generate while using the app (such as the cards in your collection, the sets you track, and your in-app preferences). When you use scanning features, the relevant image is processed solely to identify the card and is not retained for advertising or resale.

We also collect a limited amount of technical information needed to operate the service, including device type, app version, and basic usage and diagnostic events. We do not knowingly collect more than is required to run, secure, and improve the app.

How we use information

We use your information to provide and maintain the service, keep your collection and preferences associated with your account, deliver collection and lead notifications you have opted into, prevent abuse, and improve performance and reliability.

We do not sell your personal information. We do not use your data to place orders, store retailer credentials, or perform any form of automated checkout on third-party sites.

Notifications

If you enable push notifications, we use the permission granted by your device or browser only to deliver alerts you have asked for. You can revoke this permission at any time through your device or browser settings.

Service providers

We rely on a small number of reputable infrastructure and security providers to host the service, authenticate users, and deliver notifications. These providers process information on our behalf under contractual safeguards and are not permitted to use it for their own purposes.

Your choices

You may request access to, correction of, or deletion of your account data at any time by contacting us at the address below. You may also sign out, disable notifications, or stop using the app at any time.

Children

Masterys is not directed to children under 13, and we do not knowingly collect personal information from them. If you believe a child has provided us with personal information, please contact us so we can remove it.

Changes

We may update this Privacy Policy from time to time. When we do, we will revise the “Last updated” date above and, where appropriate, provide additional notice in the app.
