Privacy
The checker is designed so an ordinary check leaves no address behind.
- Your address travels from your browser to ProtectDade’s server in a POST request body — never in the page URL.
- ProtectDade’s server then queries Miami-Dade County’s public GIS services — where the authoritative records live — to answer the question.
- The address never appears in the browser URL or in the shareable result.
- Ordinary checks do not store your address. It is not written to our database, our logs, or your browser’s storage.
- Exact coordinates are not stored.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- ProtectDade is an independent civic-awareness project and is not affiliated with Miami-Dade County.
