Privacy Policy
Last updated · June 28 2026
Personal Data
I do not collect any of your data. Nothing.
Everything you do is saved on-device.
The app does not display any ads or send anything to any server (the only exception is the optional AI Coach described below, which you must explicitly enable). So the app does not track you using an advertising identifier or anything of the sort.
AI Coach
In short: The optional AI analysis sends your play data to the AI provider you chose (Claude / ChatGPT / Gemini); your API key is stored locally on your device.
The AI Coach feature is turned off by default. It only works if you explicitly enable it in Settings and add your own API key for a third-party AI provider of your choice (Anthropic / Claude, OpenAI / ChatGPT or Google / Gemini).
Only when both of these conditions are met, your performance and usage data (such as shot and session values) is sent to the AI provider you selected so it can generate coaching feedback. This data is then processed by that provider under its own privacy policy and terms of service.
If you do not enable the AI Coach and do not provide an API key, no data ever leaves your device. Your API key is stored only on your device and is never transmitted to me or to any other party except the provider you chose.
Any Question?
