Privacy Policy

Last updated: 13 November 2026. Applies to KaiTube Native 0.4.3.

Who operates KaiTube

KaiTube is an independent experimental project developed by Sank-kab. It is not affiliated with Nintendo, Google or YouTube. Public privacy contact: kaitube67@gmail.com.

Information used by the app

KaiTube requests public video information, search results, thumbnails, subtitles and audiovisual streams to provide browsing and playback. Google/YouTube receives network requests, including your IP address and the information needed to answer those requests.

Google account connection is optional. When you connect an account, KaiTube uses OAuth authorization tokens to request your YouTube channel information, subscriptions, playlists and playlist contents. It does not ask you to enter your Google password into KaiTube. The standard account flow requests youtube.readonly permission.

The optional experimental YouTube TV account feature requests the broader youtube permission as well. Google describes this permission as allowing account management. The current implementation uses it for reading experimental personalized Home, history and library feeds. These features use unofficial YouTube endpoints and may stop working.

Local storage and purpose

The app saves access and refresh tokens, token expiry and an account display name on your Switch SD card so you can remain signed in. In this version these are local JSON files without application-level encryption. Anyone who can read those files may be able to use the saved authorization. Do not share account.json or a copy of your app data folder.

KaiTube also stores settings, local video history, saved videos, recent searches and playback progress to provide preferences, library and resume features. Playback may use temporary cache files. Diagnostic logs may contain video identifiers, playback details and errors. Local history is separate from history held by YouTube.

Sharing and third parties

The inspected account implementation communicates directly with Google/YouTube; it does not send OAuth tokens to a KaiTube developer account server. Requests for thumbnails, media and subtitles are sent to the service providing the requested resource. The developer does not receive your local files unless you choose to send them for support. Inspect and redact logs before sharing them.

Google user data is used to provide the user-facing account features described here, and is not sold or used by KaiTube for advertising. KaiTube’s use and transfer of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

Retention, deletion and revocation

Local data remains on your SD card until it is replaced or deleted. Sign out in the app to remove the saved Google account token files. Signing out locally does not revoke the authorization at Google and does not erase your separate local library or YouTube history.

You can revoke KaiTube’s Google access at any time through Google account security permissions. To remove remaining local app data, close KaiTube, delete its account folder under /switch/KaiTube-Native/ and its kaitube_native_library.json, kaitube_native_settings.json and kaitube_native_session.json files under /switch/, and remove KaiTube logs and caches. Back up anything you want to keep first. Deleting local files does not delete data stored by Google/YouTube.

This website

This static website is intended for hosting on Cloudflare Pages. The hosting provider processes network requests and technical information to deliver and protect the website under Cloudflare’s privacy policy. The site does not include analytics scripts, advertising scripts, forms or an account login. Visiting it is separate from connecting your Google account in KaiTube. Do not send passwords, tokens or account files by email.

Google and YouTube policies

KaiTube uses YouTube API Services. See the Google Privacy Policy and YouTube Terms of Service. Google/YouTube controls the data stored in your Google account under its own policies.

Questions and changes

For questions or requests concerning KaiTube’s handling of data, contact kaitube67@gmail.com. This policy will be updated when the app’s data practices change; the date above identifies the current text.
