Studio Uchu AI

Studio Uchu AI

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.

Plans

Up to 70 messages / day

A relaxed daily allowance for steady practice. Each AI reply and each scoring counts as one message. Resets at 00:00 UTC.

Up to 260 messages / day

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.

Your data — US servers, never China

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:

  • AtlasCloud (United States)
  • GMICloud (United States)
  • Parasail (United States)

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.

What we store — and don't

  • We do NOT store the content of your conversations or the AI's responses on our servers.
  • We keep only minimal usage metadata to run the membership: an anonymous app user identifier or, if you choose to sign in, a Sign in with Apple identifier, your plan, daily message counts, token counts, cost, and timestamps — used solely to enforce daily limits and prevent abuse.
  • Some participating apps, including VoiceBudget, can purchase and use Studio Uchu AI without creating an account. Sign in with Apple is optional and is used to link access across supported devices or participating Studio Uchu apps. When used, it gives us only Apple's stable, app-specific identifier — not your name or email. Payments are handled by Apple; we never see your payment details.
  • Our backend runs on Cloudflare's serverless platform and transmits your messages over encrypted (HTTPS) connections. Nothing is logged or persisted in transit.
  • You can delete your Studio Uchu AI account anytime from within any participating app (Settings → Account → Delete account), which removes your membership link and usage metadata from our servers.

One membership, shared across apps

Some apps can use the subscription anonymously on the purchasing device. If you choose optional Sign in with Apple, a single Studio Uchu AI subscription can be linked across every supported Studio Uchu app — no need to subscribe again per app.

Participating apps include Talksim, KeyPets (macOS menu bar typing companion), and VoiceBudget (voice-first personal budget). Each app links here for shared membership details.
