Privacy, kept close to the work.

Tazuki is designed to keep your delivery history on your Mac. This page explains what the website and the early macOS release handle.

Last updated September 19, 2026

Website information

The Tazuki website is a static product information site. It does not currently ask you to create an account, submit a form, join a waitlist, or provide payment information.

The service that hosts or delivers the site may process basic technical request data, such as an IP address, browser details, and request time, to operate and protect the site. That processing is governed by the provider's own privacy terms.

Information in the Tazuki app

The early macOS release stores normalized delivery facts and sync state in a local SQLite database on your Mac. This can include project metadata, builds, tests, failures, trends, and timestamps returned by App Store Connect.

Tazuki performs its analysis locally. The current release does not provide a Shiina Labs account or a Shiina Labs cloud database for this information.

App Store Connect connection

When you connect Tazuki to App Store Connect, the app uses credentials you provide to request data from Apple's APIs. The private key is kept in macOS Keychain and is not written into the local SQLite facts database.

Tazuki requests data when you use its connection and sync features. Apple handles the API request according to its own terms and privacy policy.

What this release does not include

  • No advertising SDKs or tracking pixels on this website.
  • No sale or rental of personal information by Shiina Labs.
  • No website account, public profile, or social feed.
  • No beta download until the release review is complete.

Your choices

You can choose whether to connect an App Store Connect account. You can remove local Tazuki data from your Mac and revoke an API key in App Store Connect when you no longer want the connection to remain active.
