Privacy Policy for Delia
Last updated: September 3, 2026
Delia ("we", "our", "the App") is a food delivery application connecting customers with restaurants in Vietnam.
This Privacy Policy explains what information we collect, how we use it, and your choices regarding that information.
1. Information We Collect
- Account information: email address, nickname, phone number, and role (customer or restaurant owner).
- Delivery information: delivery address and GPS location, used to show nearby restaurants and calculate delivery distance/fee.
- Order information: order history, ordered items, order amounts, and delivery requests.
- Communications: chat messages and images exchanged between customers and restaurants regarding an order.
- Reviews: ratings, written reviews, and photos you choose to submit for a restaurant.
- Push notification token: a device token used to deliver order-status and chat notifications.
- Sign-in information: if you sign in with Google, we receive your email address and basic profile information from Google.
We do not collect or store payment card information. Delia currently supports cash-on-delivery payment only.
2. How We Use Information
- To operate core app features: showing restaurants, processing orders, calculating delivery fees, and enabling order tracking.
- To enable chat between customers and restaurants regarding an order.
- To send push notifications about order status and new messages.
- To display reviews and ratings to other users of the app.
- To maintain account security and prevent fraud or abuse.
3. Third-Party Services
We use the following third-party services to operate the App:
- Supabase — database, authentication, and realtime messaging.
- Cloudflare R2 — storage for uploaded images (menu photos, review photos, chat images).
- Google Firebase Cloud Messaging — delivery of push notifications.
- Google Sign-In — optional sign-in method.
These providers process data on our behalf and are contractually restricted from using it for their own purposes.
4. Data Sharing
We share order details, delivery address, and chat messages with the specific restaurant you order from,
solely for the purpose of fulfilling that order. We do not sell your personal information to third parties.
5. Data Retention
While your account is active, we retain your account and activity data to provide the service.
When you delete your account (see Section 6), we immediately delete your login credentials and personal
profile information — email address, nickname, phone number, delivery address, and push notification
token — so that the account can no longer be used to sign in.
Records of your past activity — order history, order amounts, payment method (cash on delivery),
order-related chat messages, and any reviews you posted — are retained in de-identified form (no
longer linked to your name or contact details) for 5 years in order to comply with tax
and accounting obligations, resolve disputes, and prevent fraud. These records are permanently deleted
after that period.
6. Your Choices
- You can edit your profile information (address, phone number) within the app.
- You can delete your account at any time from within the app: go to Settings → Delete Account.
This permanently removes your ability to sign in and deletes your personal profile information, subject to the
retention of de-identified activity records described in Section 5. You may also request deletion by contacting
us at the email below.
- You can disable push notifications through your device's system settings.
7. Children's Privacy
Delia is not directed at children under 13, and we do not knowingly collect personal information from children.
8. Changes to This Policy
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated revision date.
