Privacy Policy for KUU

Last updated: May 28, 2026

In short: What you spoke is yours. Your spoken content is not sent outside your device. Speech transcription and AI organization happen entirely on your iOS device, and the result is stored only in your own iCloud private database. The developer has no access. You can delete everything from inside the app at any time. The app uses minimal networking only for Apple StoreKit (KUU+ subscription) and Google AdMob ads — your spoken content is never sent to either (ads disappear with KUU+). For app quality improvement and immediate crash awareness, Firebase Analytics / Crashlytics are used only if you explicitly opt in; your spoken content is never sent there either (see Article 14).

Article 1 (General)

KUU (the "App") is an iOS application that helps you offload thoughts from your head by speaking them out loud and organizing them. The App processes information only to the minimum extent necessary to provide its features, prioritizing user privacy.

Article 2 (Information Handled)

The App handles only the following:

  1. Audio you record — Stored temporarily in a device-local cache only during transcription. Deleted immediately after processing. Never sent to any server.
  2. Transcribed and organized text — Saved locally on your device and in your iCloud private database so you can review what you have said.
  3. App settings — Theme, text size, head-water-level state, and other values required to run the App.

The App does not collect names, email addresses, phone numbers, location, contacts, calendar, photos, or device identifiers.

Article 3 (Speech Recognition and AI Organization)

Speech recognition (transcription) is performed entirely on your iOS device:

AI organization (categorization) uses an external AI by default:

Article 4 (iCloud Storage and Sync)

The App stores transcribed and organized text in your iCloud Private Database (CloudKit Private Database). This is Apple-provided storage that only you can access. The developer cannot view or retrieve any stored content.

The use of iCloud is subject to Apple's privacy policy.

Article 5 (Purpose of Use)

Handled information is used only for:

  1. Generating transcriptions from your voice and displaying them to you
  2. Categorizing transcriptions into Now / Later / Park / Release and displaying them
  3. Storing and displaying what you have spoken so you can review it
  4. Maintaining app settings

Article 6 (External Services)

The App uses the following external services. Your voice itself is not sent to any of them.

The App operates a minimal stateless server only to relay AI organization requests (no content is stored). It does not use authentication services requiring personal accounts. Analytics and crash reporting are gated on user opt-in.

Article 7 (Third-Party Disclosure)

The developer has no means to access your spoken content, transcripts, or organized results, and discloses none of them to any third party.

To deliver ads to users not subscribed to KUU+, the App sends information required by Google AdMob for ad delivery — including device identifiers, advertising ID, device language and region, coarse location, and ad interaction data — to Google (see Article 13; Google's AdMob privacy policy applies). While KUU+ is active, this transmission does not occur.

Information will only be disclosed when required by law.

Article 8 (Data Deletion)

You can delete all data at any time from "Settings → Voice & Data → Delete what's stored" inside the App. This permanently removes data both on the device and in iCloud (Private Database). Deleted data cannot be recovered.

Uninstalling the App deletes local data. iCloud data can be removed via Settings → Apple ID → iCloud → Manage Storage.

Article 9 (Security)

Article 10 (Use by Minors)

The App is rated 4+, but its nature (thought organization) presumes literacy. Minors should use it with the consent of their guardian.

Article 11 (Changes to This Policy)

This policy may be updated due to changes in law, additions to features, or changes to Apple's framework specifications. Significant changes will be announced via an app update or on the public page of this policy.

Article 12 (Contact)

For inquiries regarding this policy, please contact us through the "Developer" section on the App Store page of the App.

Article 13 (Ads and App Tracking Transparency)

When you are not subscribed to KUU+, the App displays one native ad slot between sections in the "What you said" screen, served by Google AdMob. Ads are rendered quietly to fit KUU's tone.

Article 14 (Use of Firebase Analytics / Crashlytics)

For app quality improvement and immediate awareness of production incidents, the App may use Google's Firebase Analytics (aggregated usage signals) and Firebase Crashlytics (crash reporting). This feature is OFF by default (no data sent) and only operates when you explicitly opt in via "Settings → Data & Diagnostics".
