1. Information We Collect

We collect information you provide, information generated by your use of the app, and some technical information needed to operate the service.

A. Account & Profile Information

• Account identifiers (Firebase): your user ID and sign-in identifiers.
• Email address (required for Google/Apple sign-in, when provided by the provider).
• Display name / profile name and profile photo (if you set one).
• Authentication metadata such as sign-in provider and timestamps (e.g., account creation and last login).
• Device information stored with your profile (e.g., platform and OS/app version) for reliability and troubleshooting.

B. Optional Profile Details

• Phone number and country code (only if you choose to add it). This is used for social features such as enabling in-app calling via your device’s phone dialer.
• Language preference (e.g., preferred language for translation).
• In-app preferences (e.g., notification settings and UI preferences). Some preferences are stored locally on your device.

C. Content You Create and Share

Depending on what features you use, this can include:

• Chat messages (text, timestamps, sender/recipient identifiers) and any images you attach.
• Audio content you record/upload (for example, posts to a public feed).
