Mantel

Privacy Policy

Updated August 2026

In short

  • No email, no phone number, no name, no ID.
  • No advertising trackers, and we sell nothing to anyone.
  • Private keys never reach us. Signing happens in your wallet.
  • Deleting your account removes everything we hold.

What we collect

  • Wallet addresses you link, and a signed message proving you control them. We never see or store private keys.
  • Profile details you choose to add: username, display name, bio, social links, and the artwork you pick for your page.
  • Content you create on Mantel: featured picks, wall layout, hidden lists, prices, offers and trades.
  • Your IP address, briefly, to rate limit lookups. It is not linked to your account and expires within minutes.

What we do not collect

  • No email, phone number, name or government ID.
  • No advertising trackers and no sale of data to third parties.

What others see

Your wall, username, display name, bio, links and featured pieces are public by design. Saved pieces stay private unless you make them public in settings. Your collection view, hidden pieces and spam filters are yours alone.

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, offers and settings permanently. Your NFTs live on the blockchain and are never touched.
