Our Core Privacy Commitment
Welcome to Stella Voice ("we," "our," or "us"). We firmly believe your voice and musical recordings belong solely to you. Stella Voice is engineered with a strict privacy-first architecture:
- 100% On-Device Audio Processing: Your raw voice recordings, live microphone inputs, and CoreML vocal separations are computed locally on your device’s Apple Neural Engine. We never stream, listen to, or store your raw voice recordings on remote cloud servers.
- Zero Data Monetization: We do not sell, rent, or trade your personal data, audio files, or usage analytics to advertisers or third-party data brokers.
- Privacy-Preserving Sign-In: With Apple and Google Sign-In, we only collect the minimum profile identifiers necessary to authenticate your membership and sync your preferences.
1. Information We Collect
A. Information You Provide Directly
When you register or authenticate through the App, we may receive:
- Apple Sign-In: Your unique user identifier (`sub` ID), display name, and verified email address (or your Apple Private Relay email address if selected).
- Google Sign-In: Your unique Google account ID, display name, and email address.
- Guest Mode: If you use "Explore as Guest," a temporary randomized local identifier is created on your device. No email address or personal identity is transmitted or stored on remote servers.
B. Microphone & Audio Hardware Access
Stella Voice requests access to your device's microphone (NSMicrophoneUsageDescription).
Sole Purpose: Microphone access is utilized strictly for real-time live vocal monitoring, low-latency DSP audio effects (pitch tracking, noise gating, auto-tuning, EQ, analog reverb/delay buses), and multi-track recording inside your local project container.
Retention & Transmission: Zero raw audio buffers leave your physical hardware. Microphone audio streams in volatile memory (RAM) and is written only to your local application container (Files > StellaVoice_Recordings).
C. Local File Storage & User Content
Karaoke MR tracks, backing stems, multi-track audio clips, and exported WAV/M4A master bounces are stored locally within the App’s sandboxed storage or your personal iCloud Drive directory. You maintain full ownership, deletion authority, and export rights over your files at all times.
D. Telemetry & Crash Diagnostics
We do not embed third-party tracking pixels or ad SDKs. Anonymous, aggregated crash logs may be received through Apple's native App Store Connect diagnostic reporting if you have opted in via your iOS system settings.
2. How We Use Your Information
We process personal information strictly for legitimate operational purposes:
- Authentication & Profile Sync: Identifying your account, verifying your membership tier (Standard vs. PRO Studio Master), and persisting your audio preset preferences.
- Core Feature Delivery: Providing ultra-low-latency audio mixing, real-time lyric synchronization (
.lrc), and multi-track bounce exports. - Customer Support & Legal Compliance: Assisting you with technical questions and complying with Apple App Store Review Guidelines, the General Data Protection Regulation (GDPR), and the California Consumer Privacy Act (CCPA).
3. Data Storage, Security & Cloud Infrastructure
Account profile records (User ID, Email, Subscription tier) are stored using enterprise-grade backend infrastructure provided by Supabase Inc., hosted in AWS data centers featuring end-to-end TLS 1.3 encryption in transit and AES-256 encryption at rest.
We employ strict Row Level Security (RLS) policies, SHA-256 / ES256 cryptographic token verification, and Apple iOS Keychain integration to safeguard credentials against unauthorized access.
4. Third-Party Services
Stella Voice interfaces with select industry-standard infrastructure providers:
- Apple Inc. (Sign in with Apple & StoreKit): Governed by Apple’s Privacy Policy.
- Google LLC (Google Sign-In / OAuth): Governed by Google’s Privacy Policy.
- Supabase Inc. (Database & Auth): Governed by Supabase’s Privacy Policy.
5. Your Rights (GDPR & CCPA Compliance)
Regardless of your physical residency, you possess comprehensive rights over your personal data:
- Right of Access & Portability: You may request a copy of the profile data associated with your account.
- Right to Erasure ("Right to Be Forgotten"): You may request permanent deletion of your account and related records directly within the App or by contacting our support desk.
- Right of Revocation: You can revoke microphone access at any time through iOS Settings > Stella Voice > Microphone.
6. Children's Privacy
Stella Voice is not directed to individuals under the age of 13 (or under 16 in the European Union). We do not knowingly collect personal information from children. If we discover that personal data has been submitted by a minor without parental consent, we will promptly delete the data.
7. Changes to This Policy
We may periodically update this Privacy Policy to reflect enhancements in technology or regulatory requirements. Any modifications will be posted to this page with an updated "Last Updated" timestamp. Continued use of the App constitutes acceptance of the revised terms.
