## Why this fork exists

Stock Minecraft phones home. Stock launcher pushes Microsoft accounts. Stock client struggles on low-end machines.

This fork fixes all three.

| | Stock launcher | This fork |
|---|---|---|
| Telemetry | Yes | None |
| Microsoft account | Required | Optional, never enforced |
| News fetch on launch | Yes | Hidden, no startup call |
| Plays on weak hardware | Often won't | Yes |
| Window title | Mojang branding | `racked.ru launcher` |

Full diff: [CHANGELOG.md](CHANGELOG.md).

## Trust

This is open-source. Verify the privacy claims yourself:

- [docs/NETWORK_AUDIT.md](docs/NETWORK_AUDIT.md) — every network endpoint listed, telemetry verdict
- [docs/SETTINGS_AUDIT.md](docs/SETTINGS_AUDIT.md) — default-value diffs vs upstream
- [docs/BLOAT_AUDIT.md](docs/BLOAT_AUDIT.md) — what was stripped, why

You don't have to trust me. Read the source.
