TripFun (the “App”) is operated by its developer, Wang Chuan-Wei. This policy explains how we collect, use and protect your personal data.

4. Data sharing
When you share a trip or join a collaborative one, members with the relevant permissions can view that trip's itinerary, chat, expense or location content. We do not sell your personal data, and we do not share it with third parties for cross-service personalised advertising. We may disclose data where required by law, or where necessary to protect users' safety or defend our rights.
5. How we protect your data
- All traffic is encrypted over HTTPS
- Passwords are stored as cryptographic hashes; nobody can read the original password
- Location data expires automatically and is deleted once it does
6. Data retention
- Account and trip data: retained for the life of the account, and fully erased within 30 days of account deletion
- Live location data: expires and is cleared once sharing ends
- Place photo cache: retained for up to 30 days
7. Your rights
- You can change or delete your personal data inside the app at any time
- You can turn off location sharing at any time
- You can request deletion of your account and its data through the account deletion page
- You can opt out of surveys, member events, offers and marketing messages at any time. Once you do, we will stop using your personal data to send them, though this does not affect essential account, transaction, security or system notices.
8. Children's privacy
The App does not knowingly collect personal information from children under 13. If you believe this has happened, please contact us so we can address it immediately.
9. Changes to this policy
Any revision to this policy will be published on this page. For significant changes, we will also notify you through the app.
