What stimmo does
with your data.
Plain and factual — not legal boilerplate. If anything here is unclear, ask.
No accounts, no persistent profile
stimmo has no user accounts, no login, and no persistent per-visitor profile. Each form submission is processed as an independent request: the address, surface, condition and other listing details you enter are used only to compute that one estimate and are not stored against your identity.
Third-party lookups
Producing an estimate requires two lookups against external, non-profit map data providers:
- the address you enter is geocoded to coordinates via OpenStreetMap's Nominatim service;
- nearby amenities (schools, transit, parks, and similar) are looked up via the Overpass API, which also serves OpenStreetMap data.
Both are called per-request with the coordinates needed to answer the query; stimmo does not otherwise share your input with third parties.
Share links
If you use the "share" button on a result, the estimate payload (the listing details and computed verdict — explicitly not any personal data about you) is stored in a small, self-hosted, content-addressed SQLite database so the short link keeps working when others open it. There is nothing tying a share link back to who created it.
Metrics
stimmo collects aggregate, anonymous Prometheus counters — request counts and latencies by route, and share-link open/render outcomes. These are operational metrics, not per-user tracking: they carry no IP address, cookie, or identifier tied to a specific visitor.
If a Cloudflare Web Analytics token is configured, this page also loads Cloudflare's privacy-first analytics beacon, which does not use cookies or persistent identifiers to track individuals across sites.
Infrastructure
stimmo runs behind Cloudflare, used as a reverse proxy and CDN to serve the site reliably. Cloudflare processes standard connection metadata (like your IP address) as part of routing the request, under its own privacy policy.
