Auralynx: Voice & Pulse

Explore voice and movement signals in short sessions with Auralynx. Speak a baseline phrase, answer questions, and see a simple comparison of pitch, energy and hand movement. Session indicators are for entertainment and personal reflection; they do not establish your emotional state or truthfulness.

FEATURES
• Short baseline and question sessions
• Built-in questions and your own prompts
• Signal charts, session summaries and local history
• Camera-based pulse estimates and a live signal waveform
• Share a summary only when you choose
• English, Korean, Spanish, Portuguese, French, German and Japanese

CAMERA COMPATIBILITY
Pulse estimation requires a compatible Android phone with a rear camera and flash, plus camera permission. Place a finger gently over the camera and remain still. Camera layout, lighting and movement affect readings. Some devices cannot provide a usable estimate; support and clinical accuracy are not guaranteed.

PRIVACY AND GOOGLE SERVICES
Voice and camera processing happens on your device. Audio, camera images, session scores and pulse results are not uploaded by the app to Google services. Sharing a summary sends the selected text to an app you choose. No account is required.

Google AdMob banner and occasional interstitial ads use restricted, non-personalized requests. Interstitials may appear when you return to Home after viewing voice-session results; they do not interrupt recording or pulse estimation. The app does not ask or store your age. Google services can process usage, device and diagnostic data. Firebase Analytics and Crashlytics are separate optional settings, off by default and enabled only after an explicit opt-in. Previously saved explicit choices remain in effect until changed in Settings. They are not required to start using the app. Advertising privacy choices are available where required. See the privacy policy for details.

INTENDED USE
For ages 13+. Not a medical device. It does not diagnose, treat, cure or prevent medical conditions. Consult a healthcare professional for medical advice, diagnosis or treatment. Do not use indicators to judge or pressure others.
