MASTER — Privacy Policy
Last updated: June 2026
The short version
MASTER is a card-discovery tool. It does not require an account, and it does not collect, sell, or share personal information. Your preferences, watchlist, and votes stay on your device.
What stays on your device
Your archetype profile, watchlist, hype votes, and settings are stored locally on your phone using on-device storage. They are never transmitted to us.
What our servers do
To show market analysis, the app requests card data from our backend, which aggregates public market prices (e.g. Cardmarket, eBay sold listings) and computes an AI-assisted conviction read. These requests contain only the card identifiers needed to return data — no personal identifiers.
Analytics & tracking
MASTER does not use third-party advertising or cross-app tracking. We do not build advertising profiles.
Children
MASTER is not directed at children under 13 and does not knowingly collect data from them.
Not financial advice
MASTER is a decision-support tool, not financial or investment advice. Collectible cards are not securities. Prices and signals may be delayed or inaccurate.
Trademarks
The text and imagery related to the Pokémon Trading Card Game, including card images, symbols and names, are copyrighted materials and registered trademarks owned by The Pokémon Company, Nintendo, Creatures Inc. and GAME FREAK inc. MASTER is an independent application and is neither produced, endorsed, supported, nor associated with The Pokémon Company International Inc., Nintendo, Creatures Inc. or GAME FREAK inc.
