Privacy Policy

Short version: Estua has no user accounts, no cloud telemetry server, and zero third-party ad or analytics SDKs. Its App Store privacy card reads Data Not Collected.

1. Optional context & health inputs

If you explicitly grant access to Apple Health metrics (heart rate, HRV, respiratory rate, sleep) or your microphone (solely to estimate ambient room loudness in dB), those values are mapped to synth parameters immediately in volatile device memory. Estua never records speech or transmits biometric values off your device.

2. On-device storage

Saved Seeds, preferences, your 8-band ear profile, and playback notes live inside local app storage on your phone. This landing site uses only a single optional localStorage key (aura-theme) when you toggle Light / Dark mode.

3. Purchases & billing

Optional Estua+ purchases are processed directly by Apple App Store (and Google Play upon Android release). UraLab never handles your card details or personal billing identity.

4. Contact

Questions about how Estua handles local data can always be sent directly to uralab95@gmail.com.
