liuliu (“we,” “us,” or the “app”) is a travel app for planning trips and reliving them on a 3D globe. This policy explains what we collect, why, and what choices you have. The short version: your trips are yours, we collect only what the app needs to work, and we don’t sell your data.
Information we collect
We collect the following, and nothing more:
- Account information. When you sign in, our authentication provider (Clerk) handles your credentials, including your email address or social-login identity and your name. Our own servers never store these — we only ever receive and store an opaque account identifier that links your trips to you. We never see or store your password.
- Trip content you create. The trips and events you add are stored on our servers so they sync to your device. This includes trip titles and dates, and for each event: place names, map coordinates (latitude and longitude), city names, travel and lodging details, hotel names, and any free-text notes you write. Because trips are made of places, this content includes location information that you choose to enter.
We do not collect analytics, usage tracking, or crash-reporting data, and we do not track your device’s real-time location in the background. The only location data we hold is the places you deliberately add to a trip.
How we use your information
We use the information above only to:
- Sign you in and keep your account secure.
- Store your trips and sync them across your devices so you can plan, view, and relive them.
- Render your places on the map. Map coordinates are sent to our mapping provider (Mapbox) to draw the globe and the tiles you see.
- Respond to you if you contact us for support.
We do not use your data for advertising, and we do not sell or rent it to anyone.
Service providers
We rely on a small number of trusted providers to run the app. They process data only on our behalf and only as needed to provide their service:
- Clerk — authentication and account management.
- Microsoft Azure (Cosmos DB) — secure storage of your trips and events.
- Mapbox — map rendering. It receives the coordinates needed to display your places.
Data retention and deletion
We keep your account and trip data for as long as your account is active. You can delete individual trips at any time in the app. If you want your account and all associated data permanently deleted, email us at hello@liuliu.io and we will remove it.
Your rights
Depending on where you live (for example under the GDPR or CCPA), you may have the right to access, correct, export, or delete your personal data, and to object to certain processing. To exercise any of these, contact us at hello@liuliu.io. We don’t sell personal data, so there is nothing to opt out of on that front.
Children
liuliu is not directed to children under 13, and we do not knowingly collect data from them. If you believe a child has provided us information, contact us and we will delete it.
Changes to this policy
If we change what we collect or how we use it, we’ll update this page and revise the “last updated” date above. For material changes, we’ll make a reasonable effort to notify you in the app.
