Privacy Policy

Last updated: April 9, 2026

LetsDine ("we", "us", "our") operates the LetsDine mobile application and website at letsdine.app. This policy explains what data we collect, how we use it, and your rights.

What we collect

• Phone number — used for authentication only. We do not sell or share your phone number.
• Display name — the name you choose to show your group. This is visible to other members of events you join.
• Votes and swipes — your date and food preferences within an event. These are used to calculate group matches and are visible to other group members only after all votes are in.
• Event data — event names, dates, descriptions, and participant lists that you create or join.
• Taste profile preferences — optional dietary restrictions, cuisines you always like or always avoid, used to personalize food suggestions across your events.
• Contacts (optional, on-device) — if you grant contacts permission, we read your device contact list locally so you can pick friends to invite. Only the names and phone numbers of people you explicitly choose are sent to our servers; the rest of your address book is never transmitted or stored.
• Push notification tokens — when you enable notifications, we store the Firebase Cloud Messaging / Apple Push Notification token for your device so we can send you event-related alerts. Tokens are deleted when you sign out or disable notifications.
• Device and platform information — device type (iOS, Android, desktop) and platform (native app vs. web browser), derived from your browser's user-agent header, used to track invite link conversions and improve the app experience.
• Activity timestamps — the times you first joined LetsDine and were last active, used to measure engagement and clean up inactive accounts.
• IP address — temporarily processed by our server for rate limiting and abuse prevention. We do not store IP addresses in our database long-term.

What we do NOT collect

• Precise location data (GPS coordinates)
• Photos or camera content
• Microphone audio
• Health, fitness, or biometric data
• Payment or financial information
• Advertising identifiers (IDFA / AAID)
• Contacts you do not explicitly select to invite

How we use your data

Your data is used solely to operate the app:

• Authenticate your identity via phone number or Sign in with Apple
• Show your name and votes to members of your events
• Calculate group match results from votes
• Send event-related notifications (invites, vote nudges, results)
• Apply your taste profile to personalize food suggestions
• Measure aggregate usage to improve the app

We do not sell, rent, or share your personal data with third parties for marketing purposes.

Third-party services

We use the following services to operate LetsDine:

• Google Tag Manager — used on our marketing website (letsdine.app) to measure aggregate visitor analytics. Not used inside the app itself.
• DigitalOcean — for hosting. Data is stored on servers in the United States.

Data retention

We retain your account data for as long as your account is active. Event data is retained for 90 days after the event date, then automatically deleted. You can request deletion of your account and all associated data at any time by contacting us.

You may:

• Request a copy of your data
