Privacy Policy

Effective date: July 22, 2026

The short version

There are no accounts, no sign-in, no analytics, no advertising, and no third-party services. Everything the app stores stays on your device. That's the whole policy — the rest is just detail.

What the app accesses on your device

To do its job — playing your music at a tempo matched to your cadence — Green Onions needs access to music you choose to bring in:

• Music you import from Files. When you add songs from the Files app, Green Onions copies those audio files into its own storage on your device.
• Your Apple Music / iTunes library (only with your permission). If you choose to import from your device's music library, iOS asks for your permission first. When granted, Green Onions copies the songs you specifically pick into its own storage so it can analyze and tempo-match them offline. It does not read, upload, or catalog your wider library.

In both cases the music stays on your device. It is never uploaded anywhere.

What the app collects

Nothing. Green Onions has no servers and makes no network connections. It does not collect personal information, usage data, location, contacts, identifiers, or diagnostics. Your song library, your detected and edited BPM values, and your pace settings are stored only in the app's local storage on your device.

Accounts

There are none. Green Onions does not require or offer account creation, and there is no login.

Third parties

Green Onions includes no third-party analytics, advertising, tracking, or software development kits. No data is shared with anyone because no data is collected.

Children

Because Green Onions collects no data at all, it is safe for users of any age. No personal information is ever gathered, from anyone.

Data storage and deletion

All app data lives locally on your device. You are in full control:

• Delete individual songs from within the app's Library at any time.
• Deleting the Green Onions app from your device removes all of its data permanently.

Apple

Green Onions is distributed through Apple's App Store. Any diagnostics or usage information you have chosen to share with Apple at the system level are handled by Apple under Apple's Privacy Policy, not by Green Onions. The app itself receives none of it.

Changes to this policy

If this policy ever changes, the updated version will be posted here with a new effective date. Because the app collects no data, any future change would be to clarify wording, not to expand data practices — and any material change to that would ship with a clear notice.
