Privacy Policy — Better Maps for SpareRoom

Last updated: April 23, 2026

Summary

Better Maps for SpareRoom does not use any developer-run backend and does not send your data to servers operated by the developer. Data saved by the extension — such as commute locations, preferences, cached route results, and related coordinates — is stored locally in your browser on your device.

To provide its core features, the extension may send user-provided addresses, location data, route queries, and listing-related coordinates directly from your browser to third-party services described below.

What the extension stores locally

The extension stores data in Chrome’s chrome.storage.local on your device.

This may include:

• Commute locations you save (such as name, latitude, longitude, and icon), which you create yourself in the extension.
• Listing coordinates read from SpareRoom pages and cached so the extension does not need to fetch them repeatedly.
• Cached travel times and route-related results so commute chips can load faster on later visits.
• Extension preferences and UI settings required for the extension to work properly.

You can remove this locally stored data at any time using the extension’s cache-clearing controls or by uninstalling the extension.

Third-party services contacted

The extension contacts the following third-party services only to provide its core functionality:

• Google Maps (google.com, maps.googleapis.com, maps.gstatic.com) Used to open directions pages and retrieve travel-time information for routes requested by the user.

• OpenStreetMap Nominatim (nominatim.openstreetmap.org) Used to convert addresses entered by the user into map coordinates.

• postcodes.io Used to look up UK postcodes from coordinates for Area360 links.

• CARTO tile servers (basemaps.cartocdn.com) Used to display the map preview inside the extension’s location picker.

• SpareRoom (spareroom.co.uk) Used to read listing page data, including map-related metadata, so the extension can enhance listing, search, and map pages.

The extension does not intentionally attach custom identifiers to these requests. However, third-party services may still receive standard browser and network data such as IP address, cookies, headers, and account/session information according to their own privacy policies.

What the extension does not do

• Does not send user data to developer-owned servers.
• Does not sell user data.
• Does not track browsing outside SpareRoom.
• Does not record keystrokes, mouse movements, or personal communications.
• Does not request or access device GPS location.
• Does not use remote hosted code; its JavaScript and CSS are packaged with the extension.
• Does not serve advertising.

Data retention and control

Locally stored extension data remains in your browser until it is cleared by you or removed when the extension is uninstalled.

You can delete stored extension data by:

• using the extension’s cache-clearing controls, or
• uninstalling the extension from Chrome.

Children’s privacy

The extension is not directed to children under 13 and is not knowingly designed to collect information from children.

Changes to this policy

If the extension’s data practices change, this page will be updated and the “Last updated” date above will be revised.
