How the data is used

Smell reports

The app stores the precise coordinates of the reported smell, the incident time, intensity, smell description, setting, selected impacts and any optional comment.

The full postcode may be resolved from the coordinates and stored privately to support accurate local analysis.

Public map

Exact coordinates, exact postcodes, comments and contact details are not published. The public map rounds and groups report locations before displaying them.

Campaign contact list

Email is optional on a smell report and is saved only when contact consent is ticked. Contact details are held separately from the public dataset. Once you have joined the contact list, you can leave email blank on later reports.

Messages sent through the contact form

The contact form stores the message, its category, the submission time, its administrative status and any reply email you choose to provide. A name is not requested.

You can send a message without an email address, but there will then be no way to reply directly. Messages are visible only in the private administration area and can be permanently deleted when they are no longer needed.

Technical data

No user account is created. A temporary one-way hash of the connecting IP address is used only to enforce basic anti-spam rate limits; raw IP addresses are not saved with smell reports or contact messages. Old rate-limit records are routinely removed.

Third-party services

OpenStreetMap/Nominatim is used for place search and address lookup, Postcodes.io for UK postcode data, and Open-Meteo for weather conditions. The browser contacts OpenStreetMap tile servers when a map is displayed.

Questions, corrections or deletion requests

Use the contact form. It can be submitted without a name or email address. Include an email only when you need a reply.

For a request about a particular smell report, include enough information to locate it, such as the approximate date, time and location.
