Privacy Policy

Summary: prompt-evolution collects the minimum personal data needed to deliver the service. See the sections below for details.

1. Purpose

This policy explains how the operator of the prompt-evolution app (the "App") handles user data. It is written in line with the spirit of Korea's Personal Information Protection Act (PIPA), the US Children's Online Privacy Protection Act (COPPA), and the EU General Data Protection Regulation (GDPR).

2. Personal Data We Collect

Specific items collected are disclosed on request. Contact the operator listed below for the exact items and purposes.

3. Data Stored On Your Device

The app stores the following data only on the user device. It is not transmitted off-device and cannot be used to identify an individual.

• AI coding chat logs (SQLite)

These items are stored in device-local storage; uninstalling the app permanently deletes all of them.

The app uses the following third-party services:

• OpenAI API (prompt classification — optional, only when the user configures an API key)

Each provider may apply its own privacy policy in addition to this one.

6. Cross-Border Transfer of Personal Data

The operator transfers personal data abroad as set out below (PIPA Article 28-8). You may refuse the cross-border transfer; if you do, features that depend on it may be limited.
