Overview

Esploro ("we", "our", or "the app") is a real-time fact-checking application that listens to speech, either through your device microphone or system audio, transcribes it, identifies factual claims, and checks those claims against published sources. We are committed to protecting your privacy and being transparent about how your data is collected, used, and stored.

Esploro does not require an account. There is no email, password, name, or phone number to sign up. Authentication is device-based using Apple App Attest, which cryptographically proves your device is genuine without revealing any personal information about you.

Information We Collect

Audio Data

• Microphone audio: When you press Record, the app captures audio from your device microphone. Opus-encoded microphone audio is streamed to our servers via a secure WebSocket connection for server-side transcription
• System audio: When you use the system audio capture feature (via ReplayKit broadcast extension), audio from other apps is transcribed

Transcribed Text

The text transcript of your speech (or system audio) is sent to our backend servers for claim detection and fact-checking. This includes:

• Transcript segments with timestamps and language identification
• The selected country/region and language settings

Device Identifiers

• Device ID: A randomly generated UUID created on first launch, stored securely in the iOS Keychain. Used to associate your fact-checking sessions with your device.
• Device Token: A short-lived authentication token (JWT) issued by our server after App Attest verification. Stored in the iOS Keychain.
• App Attest Key: A cryptographic key generated in the Secure Enclave, used to prove device authenticity. The key ID is stored in the Keychain; the private key never leaves the Secure Enclave.

Coarse Location

• Country/Region: You select a country/region in the app to determine which sources are used for fact-checking. This country code is sent to our servers. No GPS, IP-based geolocation, or precise location data is collected.

Usage Data

• Fact-checking results: Claims identified, verdicts, confidence scores, reasoning, and source citations returned by our fact-checking engine.
