Smell Radar is a community-based odour reporting application developed by Yahya Wijaya. This policy sets forth what data is collected, how it is used, and the rights held by all who use this application.
Data Collected
The application accesses device location to determine the coordinates of odour reports and to display nearby reports on the map. Location is accessed only whilst the application is actively in use and is never recorded in the background.
Photos attached to reports are uploaded to Firebase Storage and displayed publicly alongside the report. Adding a photo is entirely optional — reports may be submitted without one.
The application uses Firebase Anonymous Authentication to assign each user a unique identity without requiring registration or login. No name, email, phone number, or other personal data is collected.
Reports created by users (odour category, description, coordinates, and rating) are stored in Firebase Cloud Firestore and are visible to all users of the application.
How Data is Used
- To display odour reports on the map for all users
- To validate report ownership — only the creator may delete their own report
- To prevent duplicate reports from the same user within the same area (50 m radius)
- To prevent multiple ratings of the same report by a single user
We do not sell, rent, or share user data with any third party for commercial purposes.
Third-Party Services
- Firebase Cloud Firestore — report data storage
- Firebase Storage — report photo storage
- Firebase Anonymous Auth — anonymous user identity
- OpenStreetMap — map data (no user data is transmitted)
Security & Data Retention
Report data is safeguarded by Firestore Security Rules. Only the report's owner (verified through Firebase Auth UID) may delete their own report. All other operations are validated server-side.
Reports are retained until the user manually deletes them within the application. The Firebase anonymous identity is reset upon uninstalling and reinstalling the application (the user is thereafter treated as new).
Your Rights
- Delete reports — users may remove their own reports at any time
- Decline photo sharing — photos are entirely optional
- Deny location permission — you may decline, though map features will be unavailable
Changes to This Policy
Should this policy be amended, the date shown at the top of this page shall be updated accordingly. Continued use of the application following any changes constitutes acceptance of the revised policy.
