Your information stays yours.
For emergencies, call 911 and follow official emergency authorities.
Locations and preferences
Saved locations are used only to personalize relevance. Map views can show your saved places only in your own browser; other residents cannot see them. Guest data remains in this browser; signed-in data is protected by account-level access controls.
Service providers
Map tiles are served by OpenStreetMap. Authentication and private storage use Supabase when configured. Correction requests and email contributions are currently unavailable.
Address search
When you type an address in the location search, the query is sent through our server to Photon (Komoot), a public geocoder using OpenStreetMap data. Suggestions can be approximate. You can instead place a pin manually. Map tiles are supplied by OpenStreetMap.
Browser notifications
If you enable browser notifications, we store your push endpoint and encryption keys with your account in Supabase. Your browser’s push provider delivers encrypted notification payloads. Editors may send verified notices that match your saved places, radius, selected interests and minimum importance. Notices without a verified map position require an explicit All Paris radius. Your saved places are used for matching and are not included in notification payloads. Account Push preferences and quiet hours are checked before each send. Quiet hours use Paris, Ontario time (America/Toronto); sends are skipped, not queued. Delivery records help prevent duplicate sends. Turning off Push in Settings stops future sends to all your devices. Disabling a subscription removes its endpoint, keys and linked delivery records when server cleanup succeeds. You can also revoke browser permission. These are not emergency alerts; delivery is not guaranteed.
Community submissions and visit history
When enabled, anonymous database tips go to a private editor queue. We ask only for public details, coarse area and a public source, not your name, contact information or home location. A deployment-specific keyed fingerprint of your network address limits spam; neither the raw address nor its fingerprint is stored with submissions. Rate counters are cleaned after their windows expire as new updates arrive. Private submissions are retained for editorial review and are not automatically deleted; an operator must establish a retention policy before enabling intake. Submitting does not publish an update or send notifications. If the queue is unavailable, you can preview an update, but nothing can be submitted. Email contributions are currently unavailable.
Your area-scope choice and last-visit timestamp stay in this browser. New-since-last-visit labels compare source update or publication times, not the time an editor last checked a source. Clear browser data in Settings to remove guest data and browser history.
Newcomer checklist
Checklist progress is saved only in this browser. Use Reset checklist on the newcomer page or clear browser data to remove it.
Your choices
