Chess4U — AI Chess Trainer & Coach
Last updated: March 2026

Overview

Chess4U does not collect, transmit, or share any personal data. All information the app creates (your player profile, training history, achievements, and settings) is stored exclusively on your device using Apple's standard on-device storage (UserDefaults and local files). Nothing ever leaves your device.

Data We Do Not Collect

• No name, email address, or contact information
• No location data
• No device identifiers or advertising identifiers (IDFA)
• No usage analytics or crash reports sent to any server
• No third-party SDKs for advertising or tracking

On-Device Data

The app stores the following data locally on your device only:

• Player profile (name, Elo rating, skill band)
• Training session history and statistics
• Achievements and training streak
• App settings and preferences

You can delete all stored data at any time by uninstalling the app.

Audio

Chess4U uses Apple's AVFoundation framework to generate spoken coaching cues on-device via text-to-speech. No audio is recorded, stored, or transmitted.

Network Access

Chess4U does not make any network requests. The chess engine, AI coach, and all training content run entirely on your device.

Children's Privacy

Chess4U does not knowingly collect any information from children or any other users. Because no data is collected at all, the app is safe for users of all ages.
