NĀDA — Privacy Policy

This policy describes what NADA (developed by Soln.Labs) does — and does not — do with your data.

What this app does with data

• Microphone audio (used for the tuner/pitch-detection features): processed entirely on-device, in real time. Raw audio is never stored, transmitted, or uploaded anywhere — it exists only in memory for a fraction of a second before being discarded, purely to detect the pitch you're singing or playing.
• Purchase data: the one-time "Unlock Everything" purchase is handled entirely by Google Play Billing. NADA does not operate its own payment backend and never sees your card details or other payment information at any point — that is handled directly by Google Play.
• App settings (volume, voice-range preference, pitch sensitivity, light/dark theme, and your own saved custom exercises and note conversions): stored locally on your device only. Nothing is synced to any server, and nothing is shared with us or anyone else.
• Sharing feature: if you choose to share an exercise or a note conversion, the notes themselves are encoded directly into the link you send — no copy of what you share is stored on any server we operate.

What this app does NOT do

• No user accounts or sign-in of any kind.
• No analytics SDK.
• No advertising SDK — NADA has no ads.
• No crash-reporting SDK.
• No data of any kind is sold or shared with third parties.

Permissions requested

• Microphone (RECORD_AUDIO) — used only for the pitch-detection features. The app asks for this permission only the first time you actually use a feature that needs it (not on launch), and the microphone is never active while those screens aren't in the foreground.

Changes to this policy

If NADA's data practices change in the future (for example, if analytics or ads are ever added), this page will be updated accordingly, and the "last updated" date above will reflect that change.
