A focused explanation of what MyDopplerEffect stores, why it is needed, and what you can ask us to remove.

1. What We Collect

  • Email address — used for magic link authentication. We do not store passwords.
  • Solana wallet address — provided by you when connecting your wallet to mint or interact with NFTs.
  • Companion data — your AI companion's personality traits, conversation history, and game state are stored to power the experience.
  • Payment information — processed by Stripe. We never see or store your card number.

2. How We Use It

  • Mint and manage your NFT companion on Solana
  • Run your AI companion's personality, memory, and in-game behavior
  • Provision and manage your game world

4. Data Storage

Your data is stored on Google Cloud (Firestore) and encrypted in transit. Blockchain data (NFT metadata, transactions) is stored on Solana and Arweave and is publicly accessible by design.
