This Privacy Policy describes how CrispTone ("we", "us", "our", or "the App"), collects, uses, and shares information about you when you use our mobile application CrispTone (the "Service").
By installing or using Rave Music, you agree to the terms of this Privacy Policy. If you do not agree, please do not use the App.

## 1. Information We Collect
### 1.1 Information You Provide Directly
We do not require account registration. However, you may optionally provide:
- **Last.fm credentials** — only if you choose to enable Last.fm scrobbling. The authentication is performed through Last.fm's own browser-based login. We store only the resulting session token on your device — we never see or store your Last.fm password.
- **Search queries** — stored locally on your device to power search history and suggestions.
### 1.2 Information Stored Locally on Your Device
The following information is stored **only on your device** and never transmitted to our servers:
- Your music library scan results (file paths, metadata such as title, artist, album, duration)
- Playlists you create, including "Liked" songs
- Listening history (which tracks you played and when)
- Search history
- Songs you've saved for offline playback
- App preferences (theme, equalizer settings, crossfade duration, language, etc.)
You can clear all locally stored data at any time by clearing the app's data through Android Settings.
### 1.3 Information Automatically Collected by Third-Party Services
When you use Rave Music, the following information may be collected by integrated third-party services (see Section 4 for details):
- **Advertising ID (Android AAID)** — used by ad networks for ad personalization and fraud prevention.
- **IP address** — used to approximate your country and serve relevant ads.
- **Device information** — device model, OS version, language, screen size, mobile carrier, network type.
- **App interaction events** — which ads you viewed, clicked, or dismissed.
- **Approximate country** — derived from your IP via third-party country-lookup services (ip-api.com, ipwho.is, ipapi.co, api.country.is) to set a default content region.
We do not collect your precise location, contacts, calendar, photos, microphone audio, or any other sensitive personal information.

## 4. Third-Party Services
CrispTone uses the following third-party services. Each has its own privacy policy that governs how it handles your data.

### 4.3 Country Detection

- api.country.is — https://api.country.is/
- ipapi.co — https://ipapi.co/privacy/
- ip-api.com — https://ip-api.com/docs/legal
### 4.4 User-Installed Plugins
CrispTone includes a plugin system that lets you connect to third-party online music catalogs. These plugins are **not provided by us** — they are installed by you from URLs you choose. When you use a plugin, your device communicates directly with that plugin's hosted servers. We do not control, store, or have visibility into the data exchanged between your device and these third-party services.
You are responsible for reviewing the privacy practices of any plugin you install.

- **When required by law** — to comply with legal obligations, court orders, or government requests
- **In the event of business transfer** — if our app is acquired or merged, your data may transfer subject to this Privacy Policy
We do **not** share your local listening history, playlists, or library with anyone.
