# Privacy

BMM Miner Launcher is local-first. This Early Access release has no account system, analytics, telemetry, advertising SDK, remote configuration, or BMM server connection.

It stores the following on the user's computer:

- public wallet address
- worker name
- selected pool and performance settings
- verified XMRig, SRBMiner-MULTI, MO-Miner or BzMiner files and generated runtime configuration
- up to seven recent mining logs
- local developer-fee cycle counters and a random eight-character worker identifier

The launcher contacts GitHub to check and download the selected official mining-engine release. The selected engine contacts the primary pool and, if configured, a backup pool. During the disclosed 72-second BMM developer-fee interval, the same selected pool receives BMM's public payout identity and an anonymous random BMM worker name instead of the user's saved payout identity. A pool necessarily receives the active public wallet or pool username, worker information, IP address, submitted shares, and other protocol data according to that pool's own privacy practices.

Developer-fee state does not contain a private key, password or payout address. The BMM public receiving destinations are release data, not secrets. The fee percentage and interval are fixed locally and are not controlled by a remote service.

The launcher does not need and must never be given a wallet seed phrase, private key, wallet password, or exchange password.
