1. Introduction
urara (the "Service") is an AI voice conversation service provided by Kazuhiro Tamura (an individual developer, the "Developer"), available as an iOS app and via web browsers. This Privacy Policy explains what information is collected in connection with the Service and how it is handled.
2. Information We Collect
2.1 Voice data
While you are on a call, your microphone audio is transmitted in real time to the Realtime API of OpenAI, L.L.C. ("OpenAI") and used to generate voice responses.
Voice data is not stored on the Developer's servers or infrastructure. Processing takes place on OpenAI's API, and its handling is subject to OpenAI's privacy policy and API terms.
2.2 Usage data
Call start/end times, call duration, and your plan (consumption of available minutes) are recorded on the Developer's servers (Cloudflare Workers / D1 database) to manage usage limits.
The content of your conversations (what is said) is not recorded or stored.
2.3 Purchase and payment information
Purchases in the iOS app are made via Apple In-App Purchase through the App Store; purchases on the web version are processed by Stripe, Inc. (through the systems of RevenueCat, Inc.). Payment details such as credit card numbers are not collected or stored by the Developer; they are managed by Apple and Stripe respectively.
The Developer receives only transaction information needed to verify that a purchase is valid (transaction ID, product type purchased, etc.).
2.4 Account information
In the iOS app, your account is identified via Sign in with Apple through an anonymous identifier issued by Apple. Direct personal information such as your name or email address is not collected when Apple restricts its provision (e.g., "Hide My Email").
On the web version and the Android version, your account is identified via Google Sign-In through an account identifier (a numeric ID) issued by Google. The Developer's servers store only this identifier; your name and email address are not stored.
2.5 Device information
General technical information such as operational status and error logs may be collected (no dedicated log collection infrastructure is currently in place).
3. Purposes of Use
To provide the Service's voice calling features
To manage usage limits (monthly minutes) of subscription plans
To prevent fraudulent use and operate the Service stably
To analyze and improve the Service (conversation content itself is not included)
