How it is used

Wallet addresses are used to read the NFTs they hold through public blockchain indexers (Helius) and to show market data (Magic Eden). Everything else exists only to run the features you use.

Minors

Mantel is not directed at children and does not knowingly collect data from them.

Deleting your data

Settings, then Delete account removes your account, username, page, messages, offers and settings permanently. Your NFTs live on the blockchain and are never touched.
