Privacy Policy
Last updated: October 5, 2026
CleanSweep SG ("we", "our", or "us") respects your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard information when you use the CleanSweep SG app and website (together, the "Service"), operated by Yopa.ai.
1. Information we collect
- Account information: if you sign up by email, we collect your email address and a password (stored securely by our authentication provider, Firebase Authentication — we never see your plain-text password). If you sign in with Google, we receive your email address from Google and do not handle a password at all.
- Nickname: you choose a public nickname shown to other users on reports, comments and the leaderboard. Your email address is never shown publicly.
- Location data: when you report litter, we collect the GPS coordinates you pin. We request location access only when you actively use the map or reporting feature.
- Photos: you may upload a photo when reporting litter and when confirming a clean-up. Photos are stored with our cloud storage provider (Firebase Storage) and shown publicly on the map to other users.
- Device and push notification data: basic device information (model, OS version) to keep the app working, and, if you enable push notifications, a device token used to deliver them. You can turn push notifications off at any time in Settings.
- Usage data: actions like reports made, clean-ups confirmed, and comments, used to run the leaderboard and improve the Service.
- Advertising data (app only): we show ads through Google AdMob. AdMob and Google may collect device and advertising identifiers to serve and measure ads. If you are located in the EEA, UK or Switzerland, you will see a consent message before any personalised advertising, and you can manage your choices there. See Google's Privacy Policy for how Google processes this data.
2. How we use your information
- To display reported litter locations on the map.
- To let the community confirm clean-ups and track community impact.
- To calculate leaderboard standings.
- To send you notifications you've opted into (e.g. comments or activity on your reports).
- To review content flagged by other users and take moderation action where needed (see Section 3).
- To forward litter report details to Singapore's National Environment Agency (NEA) to support public cleanliness efforts.
- To operate app features, including advertising, and to fix bugs.
- To comply with legal obligations.
3. Content moderation
Other users can flag a report's photo or the reporting user as inappropriate. Flagged content is reviewed by our team, who may remove the report and photo, and may suspend or delete accounts that violate our Terms & Conditions.
4. Sharing your information
We do not sell your personal data. We share information only in these cases:
- Service providers: Firebase/Google Cloud (authentication, database, storage, push notifications), Google AdMob (advertising), and OpenStreetMap (map tiles). These providers process data on our behalf, or in AdMob's case, as an independent advertising provider under its own privacy policy.
- NEA: litter report details (location, photo, timestamp) are forwarded to NEA to support public cleanliness efforts. We do not include your email address in these reports.
- Sponsors: sponsors appearing on the in-app Sponsors Wall receive only aggregate, anonymous view and click counts for their own listing. We do not share your personal information with sponsors.
- Legal requirements: if required by law, regulation, or court order in Singapore.
5. International data transfer
Our service providers (Firebase/Google Cloud, Google AdMob) may process and store data on servers located outside Singapore. Where this happens, we rely on these providers' standard contractual and security safeguards to protect your information.
6. Data retention
- Litter reports and their photos are automatically removed from the live map and deleted from storage: generally within one week if unresolved, or within 24 hours of being marked cleaned.
- If you delete your account via Settings, your profile, nickname, reports and photos are deleted immediately. This cannot be undone.
7. Your rights
Under Singapore's Personal Data Protection Act (PDPA), you have the right to:
- Access the personal data we hold about you.
- Request correction of inaccurate data.
- Withdraw consent for certain processing.
- Request deletion of your account and data — you can do this yourself at any time via Settings → Delete account, or by contacting us.
To exercise these rights, contact us at support@cleansweepsg.com.
8. Security
We use industry-standard security measures, including encryption in transit and secure cloud infrastructure, to protect your data. No system is completely secure; please use a strong password and keep your login credentials confidential.
9. Children's privacy
Our Service is not directed at children under 13, and you must be at least 13 to use it. We do not knowingly collect personal information from anyone under 13. If we learn we have done so, we will delete that information.
10. Changes to this policy
We may update this Privacy Policy from time to time. We will note material changes with an updated "Last updated" date above, and where appropriate, notify you via email or an in-app notice. Continued use of the Service after a change constitutes acceptance of the updated policy.
