Privacy Policy

Last updated: May 18, 2026

1. Data we store

Kasokuon stores only your Garage presets (car name, selected engine voice ID, pitch / reverb / volume parameters) on-device. We do not collect name, email, phone or any other personal identifier.

2. Location data

Kasokuon uses CoreLocation (GPS) to display speed and compute the 0-60 timer. Location is processed strictly on-device and never transmitted to any server. We do not request Always permission; only When-In-Use.

3. Motion sensors

We use CoreMotion (accelerometer) for the G-meter and automatic 0-60 trigger. The data stays on-device and is never transmitted.

4. Microphone and recording

Kasokuon does not request microphone access. The app records nothing — neither engine noise nor conversation.

5. Bundled audio

All bundled engine sounds are licensed assets (Creative Commons or commercially licensed). The Credits screen lists every source.

6. Analytics

We collect anonymous launch and crash statistics via Firebase Analytics. We never transmit driving data (location, speed, acceleration, etc.).

7. Notifications

We send local notifications for morning, evening, weekly summaries and new engine voices. You can disable them at any time in Settings.
