Privacy Policy

Last updated: 12 June 2026

This policy covers the Soloist family of apps — Soloist (guitar), Soloist Violin, and future Soloist instrument apps. Every Soloist app is built so that the most sensitive thing about you — the sound of you practising — never leaves your device.

Audio

All listening, tuning, transcription, and grading run entirely on your iPhone. No audio recording, microphone data, or transcription is ever uploaded to our servers. Our backend has no audio endpoints at all.

What does reach our servers

Coach messages — if you use the in-app Coach, the messages you type and a short numeric summary of your latest graded take (e.g. timing and pitch percentages) are sent to our servers to generate a reply, along with a random per-install identifier used for monthly usage limits. Coach conversations are not used to identify you and are not sold or shared.
Purchase verification — if you subscribe to Pro, Apple's signed purchase receipt is verified by our server to activate your subscription. It contains transaction details, not your name or payment information.

What we don't do

No account or email is required to use any Soloist app.
No advertising, no trackers, no third-party analytics SDKs.
We do not sell or share personal data with anyone.

Practice data

Your lesson progress, takes, and stats are stored on your device (and in your personal iCloud where you enable it). We cannot read them.

Data retention & deletion

Server-side data is limited to anonymous usage counters and purchase entitlement records, retained while your subscription is active. Email mitsi@playsoloist.com to request deletion of any server-side data.

Children

Soloist apps are not directed at children under 13 and collect no personal information from anyone.
