An optional membership that powers smarter cloud AI inside Studio Uchu apps. One membership is shared across every supported app. The app you use never collects or sends your data on its own — only Studio Uchu AI does, and only when you choose to use it.
A relaxed daily allowance for steady practice. Each AI reply and each scoring counts as one message. Resets at 00:00 UTC.
For heavy daily practice across one or more Studio Uchu apps. Same one-message-per-reply-or-score model. The daily cap is an upper limit and is not guaranteed when providers are busy.
Subscriptions are billed through Apple and managed via RevenueCat. You can upgrade, downgrade, or cancel anytime from your device's subscription settings.
The app you are using does not collect, store, or transmit your data on its own. Data leaves your device only when you actively use Studio Uchu AI (the cloud membership).
When you use Studio Uchu AI, the text you send and the AI's replies pass through our server to large-language-model providers. We restrict inference to United States–based providers only:
We do not route your data to China-based providers. These providers are configured for Zero Data Retention (ZDR): they do not retain your prompts or the model's responses, and your data is not used to train models.
Because your membership is tied to your Apple account, a single Studio Uchu AI subscription works across every Studio Uchu app that supports it — no need to subscribe again per app.
