Privacy

The checker is designed so an ordinary check leaves no address behind.

  1. Your address travels from your browser to ProtectDade’s server in a POST request body — never in the page URL.
  2. ProtectDade’s server then queries Miami-Dade County’s public GIS services — where the authoritative records live — to answer the question.
  3. The address never appears in the browser URL or in the shareable result.
  4. Ordinary checks do not store your address. It is not written to our database, our logs, or your browser’s storage.
  5. Exact coordinates are not stored.
  6. To count unique properties and repeat interest without keeping addresses, the server may record a keyed fingerprint: an HMAC-SHA-256 value derived from the normalized address and a server-held secret. The fingerprint does not reveal the address by itself; because ProtectDade holds the secret, it does allow ProtectDade to recognize when the same property is checked again. It is stored instead of the address, not alongside it.
  7. Coarse, privacy-preserving data may be recorded with each check: the result type, tier, alignment, ZIP code, an approximate area cell (H3 resolution 7, roughly a five-square-kilometer hexagon), campaign parameters, device category, and timing. Not the address, and not the exact location.
  8. The interactive map loads its basemap from OpenFreeMap, built on OpenStreetMap data. When the map loads, those third-party servers receive ordinary network information (such as your IP address and browser details) and the map-tile requests for the area shown. The map is optional to your result: if it does not load, your result is unaffected, and your typed address is never sent to a map provider.
  9. If you sign up for updates, we keep your email, optional first name, your consent record, and — if you sign up from a result — only that result’s alignment, tier, and ZIP code. Never the address you checked, its folio, or its coordinates.
  10. Retention: check analytics and engagement events are kept in aggregate-friendly form and reviewed at least annually; rows older than 24 months are deleted. Subscriber records are kept until removal is requested. ProtectDade is an informational project and does not operate customer support; its public channel is Instagram.
  11. Shared results never include your address. The share text and result card carry jurisdiction context — the municipality name (for example “UNINCORPORATED MIAMI-DADE” or a city name) — along with the alignment and tier.
  12. ProtectDade is an independent civic-awareness project and is not affiliated with Miami-Dade County.
