Privacy Policy

Last updated October 6, 2026

This Privacy Policy explains what information the Momento'd mobile app ("Momento'd", "we", "us"), operated by Alan Zhang, collects, how it's used and shared, and the choices you have. By using Momento'd you agree to this policy and to our Terms of Use.

1. Information we collect

Information you give us

• Account: your email address and password. Passwords are handled by Firebase Authentication, and we never see them.
• Profile: your username and display name, and a profile photo if you add one.
• Trips: trip titles, highlights, dates, the places you add and their times, and the photos you attach.
• Activity: the people you follow, trips you like or save, trips you share and the collaborators you invite, and people you block.
• Reports and feedback: what you report and why, and anything you send us through Feedback.
• Terms acceptance: which version of the Terms of Use you agreed to, and when.

Information from your device

• Location (only if you allow it, and only while the app is open): used on your device to center the map. When you search for a place, your approximate location is sent along with the search so nearby results come first. We don't save your location or attach it to your account, and the app never uses location in the background.
• Photos (only the ones you pick): the app reads only the photos you choose to add to a trip or your profile.
• App integrity: to protect our servers from abuse, the app uses Firebase App Check, which uses Apple's App Attest or DeviceCheck (or Google Play Integrity on Android) to confirm requests come from the genuine app. This doesn't identify you.
• Technical data: like any online service, our providers receive basic technical information such as your IP address, device type and operating system when the app connects to them. Expo may receive similar information when the app checks for updates.

2. How we use your information

• To run the app: your account, your trips, sharing and collaborating, following, likes and saved trips.
• To show maps and suggest places.
• To keep the community safe: we automatically check photos for unsafe content before they're accepted, review reports, and remove content or accounts that break our Terms.
• To answer your feedback and support requests.
• To protect the service against fraud and abuse, and to meet legal obligations.

We don't use your information for advertising, and we don't build advertising profiles.

3. Who can see what

• Your profile (display name, username, photo, follower and following counts) and the people you follow are visible to other signed-in Momento'd users.
• Trips you post are visible to all signed-in users, who can like, save or copy their itinerary. Your likes are visible to people who can see the trip.
• Trips you share by link can be opened by anyone signed in who has the link.
• Private trips are visible only to you and the collaborators you invite.
• Never shown to other users: your email address, your saved trips, who you've blocked, and what you've reported. A person you block or report isn't told.

4. Service providers we share information with

We don't sell or rent your information. We share it only with the providers that run parts of Momento'd for us, and only as needed for that purpose:

• Google Firebase (Authentication, Cloud Firestore, Cloud Storage, Cloud Functions, App Check, Hosting): stores your account, profile, trips and photos, and runs our server code.
• Google Cloud Vision: checks photos you upload for unsafe content (nudity or violence). Photos are sent for this check only.
• Google Maps Platform (Places): place search and place details. Your search text and approximate location go through our server to Google.
• Apple Maps (on iPhone) or Google Maps (on Android): displays the map.
• Expo: delivers app updates.
• Gmail (Google): when someone submits a report, a copy of it is emailed to our moderation inbox so we can act on it promptly, usually within 24 hours.

We may also disclose information if the law requires it, to respond to valid legal requests, or to protect the safety of our users or others, for example by reporting child sexual abuse material to the authorities.

5. How long we keep it

• We keep your information for as long as you have an account.
• When you delete your account (Settings → Delete Account), we delete your profile, profile photo, trips and their photos, likes, saved trips and follows, and remove you from trips shared with you.
• Reports, and copies of reported content, may be kept after deletion when we need them to keep the community safe, enforce our Terms or meet legal obligations.
• Feedback you sent may be kept so we can follow up and improve the app.

6. Your choices and rights

• Access and correct: view and edit your profile in the app at any time.
• Delete: delete your account and its data from Settings.
• Control visibility: keep trips private, unpost them, or stop sharing them.
• Permissions: you can allow or deny location and photo access, and change your choice anytime in your device settings. The app still works without them, with fewer features.
• Other requests: depending on where you live, for example in the EU, UK or California, you may have rights to access, export, correct, delete or restrict the use of your information, and to complain to your local data protection authority. Email us to make a request.

7. Children

Momento'd isn't meant for children under 13, and we don't knowingly collect information from them. If you believe a child under 13 has an account, contact us and we'll delete it.

8. Security

Your information is stored with Google Firebase and protected by access rules that limit who can read and change it, and by encryption in transit. No system is perfectly secure, but we work to protect your information and fix problems quickly.

9. Where your information is processed

Our providers may process and store your information in the United States and other countries. Wherever it's processed, we protect it as this policy describes.

10. Changes to this policy

We may update this policy from time to time. If the changes are significant, we'll let you know in the app. The date at the top shows when it last changed.

11. Contact
