# NoCharge

> NoCharge is a quiet arcade of free browser games — no accounts, no cloud
> profiles, and scores that stay in the browser. Every game has documented
> controls, a full guide, calm default settings, and ads kept outside gameplay.

Key details:

- Free model: every game and tool opens with no account, subscription, or download.
- Local-only scores and progress: localStorage only; no server-side profiles or cross-device sync.
- Quiet Arcade voice: calm defaults, untimed modes where the genre allows, reduced-motion support.
- Ads: one labeled AdSense banner before the footer on eligible pages; never inside the game canvas or play loop.
- Consent: analytics stays off until the visitor allows it; advertising choices use Google's Privacy & messaging message.
- Accessibility: visible focus, documented keyboard paths where the game supports them, non-color-critical states in Color Flip, and `prefers-reduced-motion` honored.
- Honesty limits: no fake rankings, no claims of cognitive benefit, no "works on every network" promises. School or locked-network play depends on the local network.
