Product-specific Android schedule. This schedule supplements the separate Terms and Privacy Policy for package com.ryantinklepaugh.tune.
Product purpose
Tune is a controlled acoustic-calibration decision journal that qualifies the route, compares repeatable matched trials, changes one variable, and requires independent verification before certification.
Current data and permission boundary
- app-private rooms, listening positions, one-variable session definitions, and timestamps
- derived response points, route and microphone labels, sample rate, level, latency, confidence, repeatability, and capture lineage
- tested values, reasons, rankings, selection, verification result, decision notes, and local certificates
- purchase entitlement and legal-choice evidence
Foreground microphone access is requested only when you start a measurement. Tune plays a known sweep, analyzes AudioRecord buffers on the device, and discards raw samples after analysis without saving or uploading them. A certificate leaves the app only when you direct an Android share action.
Required safety boundary
Tune is a comparative acoustic experiment and decision aid, not a hardware calibration laboratory, hearing-safety monitor, professional acoustic design, or guarantee of sound quality. Built-in and wireless routes are magnitude-only. Timing claims require a qualified full-duplex wired or USB route and representative physical-device validation.
Limited mode
After a decline or withdrawal, the following remain available:
- read-only local Calibration Sessions and their derived evidence
- export of an already-certified local PDF plus local deletion controls
- legal, support, subscription-management, and purchase-restoration controls
The following remain unavailable until the current documents are affirmatively accepted:
- new microphone capture
- new or edited sessions, trials, rankings, verification, or certification
- new purchases
Legal choices and verification
A decline or withdrawal takes effect locally at once and remains limited without recurring prompts. A current affirmative choice unlocks ordinary app access after it is durably stored on the device; signed-receipt delivery may retry in the background. Android proof is recorded separately from iOS proof. A service outage does not silently convert a decline into acceptance or relabel an iOS receipt as Android.
Release state
This document describes Android build 2 (1.1.0), currently a Google Play release candidate and not a public availability claim. The Play listing and purchase sheet, when public, control current availability and transaction details.
