Data source

Import / export

Only local JSON is processed. Imported data is stored in browser localStorage and is never uploaded; it remains available after a refresh.

Live AI (off by default)

The public copy stores no API key in the browser. A compatible endpoint configured by the operator is called only after explicit server-side opt-in; the local rule engine remains the default.

Security boundaries

  • No third-party map tiles, search APIs, or telemetry requests.
  • The online demo exposes only read-only synthetic data and a disabled live-AI endpoint; there is no database or admin interface.
  • Logs omit request bodies, query strings, and credentials.
  • Imports are validated for fields, length, numeric ranges, and HTML characters.
  • The page uses a strict CSP and loads no external scripts or styles.

Import format

Accepts one district object or a { "district": { ... } } wrapper. Up to 50 stores with coordinates within ±3 km.
