Last updated: September 10, 2026

Overview

Wakatta ("the App") is a Japanese language learning app. Your privacy is important to us. This policy explains what data the App collects and how it is used.

Data Collection

Wakatta does not collect, store, or transmit any personal data to our servers. The App does not require an account, does not use analytics or tracking, and does not contain advertising.

Local Data

Your study progress, vocabulary lists, and app preferences are stored locally on your device using Apple's SwiftData framework. This data is not transmitted to any server and is not accessible to anyone other than you.

Third-Party Services

The App connects to the following third-party services:

• Jikan API — To search for anime and manga titles. No personal information is sent.
• TMDB API — To search for movies and J-dramas. No personal information is sent.
• AI Providers (optional) — If you choose to use the AI tutor feature, the App connects to Anthropic (Claude) or OpenAI (ChatGPT) using an API key you provide. Your conversation messages are sent to the provider you select. Wakatta does not store or have access to your API key beyond your device.

API Keys

If you use the AI tutor feature, you provide your own API key for Anthropic or OpenAI. This key is stored locally on your device and is never transmitted to our servers. Your use of these services is subject to their respective privacy policies.

Children's Privacy

The App does not knowingly collect any personal information from children.
