Privacy Policy
1. Overview
This extension is provided by an individual developer. Its sole purpose is to display
the distance from a user-configured base city to any city name the user middle-clicks
on a webpage. The extension is designed with privacy in mind: it collects no personal
data and contains no advertising or tracking code.
For privacy-related questions, contact: yac116@gmail.com
2. Data processed
| Data | Purpose | Where stored |
|---|---|---|
| Name and GPS coordinates of the user-selected base city | Calculating the distance between the base city and any city name clicked by the user | Locally on the user’s device via the browser’s built-instorage.sync API. Synced across devices signed into the sameOpera/Google account if sync is enabled by the user. |
| The city name clicked by the user on a webpage | Geocoding — obtaining GPS coordinates for the clicked name via the Nominatim API in order to calculate the distance |
Not stored. Sent once to the Nominatim API and immediately discarded after the response is received. |
3. Data NOT collected
The extension does not collect, store, or transmit:
- Browsing history or URLs of visited pages
- Content of any webpage
- Personal information (name, email address, physical address, etc.)
- Device or browser identifiers
- Analytics, telemetry, or crash reports
- IP address or geolocation of the user’s device
4. Third-party data sharing
The extension sends the clicked city name as a plain text query to the public
Nominatim geocoding API operated by the OpenStreetMap Foundation
(nominatim.openstreetmap.org).
This is necessary to determine the GPS coordinates required to calculate the distance.
No other data is shared with any third party. The extension contains no
advertisements, social-media widgets, or analytics scripts.
Data processing by the OpenStreetMap Foundation is governed by their own
Privacy Policy.
5. Permissions
| Permission | Reason |
|---|---|
storage |
Saving and optionally syncing the user’s chosen base city (name + GPS coordinates) across devices. No other data is stored. |
Host access: nominatim.openstreetmap.org |
Fetching GPS coordinates for the clicked city name from the public OpenStreetMap geocoding API. Requests are made only when the user middle-clicks on text. |
Content scripts on <all_urls> |
Listening for middle-mouse-button clicks on any webpage so the user can click any city name regardless of which site they are visiting. The content script does not read, modify, or transmit page content. |
6. Data retention and deletion
The only data retained by the extension is the base city name and its GPS coordinates,
stored via storage.sync. This data is:
- Deleted automatically when the extension is uninstalled.
- Removable at any time by the user through the extension’s settings page.
- Never sent to the developer or any server controlled by the developer.
7. Children’s privacy
This extension does not knowingly collect any information from children under
the age of 13. It collects no personal data from any user.
8. Changes to this policy
Any material changes to this privacy policy will be reflected by updating the
„Last updated” date at the top of this document. Continued use of the extension
after changes are published constitutes acceptance of the updated policy.
