## What is Shizumo?

Shizumo is a privacy-first noise meter that measures ambient sound for **10–30 seconds** and saves a snapshot so you can review trends over time—without chasing noisy moment-to-moment numbers.

# Highlights
- Tap-to-save snapshots: tap → measure 10–30s → saved to history
- Place-based guidelines: recommended dB for common places + adjustable levels
- Custom places (up to 3): add your own places with name, icon, and baseline dB
- Quiet Score: see how often you stay under your guideline
- Readable history: date grouping + mini trend sparkline
- Export: share your history as CSV
- Languages: Korean / Japanese / English

# Privacy
- Requires Microphone permission to estimate sound level (dB).
- No raw audio is recorded, stored, or transmitted.
- Only on-device settings and summary results may be stored locally.

# Ads
- To keep the app free, a banner ad may be shown.

Note: dB values are estimates and can vary by device/environment.
