Privacy Policy

Last updated: September 30, 2026

Cambio is a multiplayer card game app. This policy explains what information Cambio collects, how it's used, and how you can delete it.

Information we collect

• Email address - used to create and sign in to your account, either directly or through Sign in with Apple / Sign in with Google.
• Username - chosen by you when you create your account. Your username is visible to other players you're matched or friended with.
• Friend connections - the other Cambio players you've added as friends.
• Gameplay data - match history, including who you played against, final scores, and match outcomes.
• Bug reports - if you send one from the app, the description you write, your app version and platform, and your username and email address so we can reply.
• Push notification token - if you allow notifications, a token for your device, used only to send you game invites and friend request alerts.

We do not collect your location, contacts, photos, camera or microphone access, or advertising identifiers. Cambio does not use third-party analytics, advertising, or tracking SDKs.

How we use this information

Your information is used solely to operate the app: authenticating you, matching you with opponents, displaying your friends list, and showing your match history. We do not sell your information or use it for advertising.

Who we share information with

Cambio's backend is hosted on Supabase, which stores your account and gameplay data on our behalf as our infrastructure provider. If you sign in with Apple or Google, those companies process your authentication according to their own privacy policies. When you send a bug report, it is emailed to our support inbox through Resend, including your description, username, and email address. Push notifications are delivered through Expo's push notification service, which receives your device's push token and the notification's text. We do not share your information with any other third party.

Data retention and deletion

You can permanently delete your account at any time from within the app: go to Profile -> Delete account. This immediately and permanently deletes your email, username, friend connections, match history, bug reports, and push notification tokens. Bug report emails already delivered to our support inbox are not removed automatically; ask us and we will delete them. This action cannot be undone.

Children's privacy

Cambio is not directed at children under 13, and we do not knowingly collect personal information from children under 13.

Changes to this policy

If this policy changes, the updated version will be posted at this same URL with a new "last updated" date.
