Privacy Policy
Us Back Then respects and protects your personal information. Exact locations are not shown to other users. Location sharing begins only when you choose to turn it on and remains on until you turn it off.
1. Personal information we collect
Email address, nickname and user ID.
Approximate location information.
Optional profile details you enter, such as schools, enrollment years, military units, clubs and their schools or organizations, workplace area, home area and hometown.
Chat requests, messages, blocking and reporting information.
Strawberry reservation and usage records.
Push notification tokens and your selected app language.
Purchase information: the store used (Apple App Store or Google Play), product ID, purchase time, purchase environment and quantity credited.
One-way hashes of transaction or order identifiers for purchase verification and duplicate-credit prevention.
2. Why we collect personal information
Registration and sign-in; discovering nearby users; matching shared profile details such as schools, military units and clubs; chat requests and conversations.
Blocking, reporting, safe service operation, and app display and push notifications in your selected language.
Reserving, spending and releasing strawberries.
Verifying purchases, crediting strawberries, preventing duplicate credits and fraudulent payments, and handling cancellations, refunds and payment enquiries.
Investigating service errors and improving service quality.
3. Location information
We may use location information to help you find people nearby. It is used only when you explicitly choose to share your location in the app.
Location sharing is not enabled automatically at registration. You must turn it on yourself. It remains enabled until you turn it off, including when the app is in the background or closed.
Your exact location is not disclosed to other users. Only an approximate location with an offset is displayed, for nearby discovery and matching.
You may stop sharing your location in the app settings at any time. You will then no longer appear on the map or nearby-user list.
4. Manual check-in
Us Back Then does not provide automatic check-in. You must explicitly activate location sharing to make yourself visible on the map or nearby-user list.
Sharing starts only at your request and remains on until you turn it off in the app. You can stop sharing at any time.
5. Retention
Personal information is retained while you use the service. When you delete your account, account-related personal information such as your profile, location and chat information is deleted.
Minimum purchase-verification information and account-deletion processing records may be retained separately to meet legal retention obligations, prevent duplicate credits or abuse, and handle refunds or disputes. They are retained until those purposes are fulfilled or for the period required by applicable law.
Purchase-verification records do not include card or bank account numbers. Transaction and order identifiers are stored as one-way hashes where possible.
6. Disclosure to third parties
We do not sell personal information or provide it to third parties for advertising performance measurement. Information may be disclosed exceptionally when required by law.
7. External services
We may use Firebase Authentication, Cloud Firestore, Expo Push Notification, Apple App Store, Google Play and other external services to provide registration, sign-in, data storage, notifications, payment authorization and purchase verification.
8. Payment information
Apple or Google handles payment authorization and payment-method information. Our server does not directly collect card or bank account numbers. It processes only the minimum transaction information needed to verify purchases and credit strawberries.
9. Account deletion, purchases and refunds
Deleting your account removes any remaining strawberries; they cannot be transferred to another account.
Account deletion does not automatically cancel or refund store payments. If you need a refund, use the refund process of the Apple App Store or Google Play that processed your payment before deleting your account.
Minimum purchase-verification records may be retained separately after deletion for duplicate-credit prevention and refund or dispute handling, as described above.
10. Your rights
You can request deletion of your personal information through the account deletion feature in the app at any time. For access, correction, deletion or restriction-of-processing enquiries, contact the email address below.
11. Age requirement
The service includes location-based discovery of nearby users and is intended for people aged 18 or older. People under 18 may not use the service.
