Privacy Policy
This Privacy Policy describes how the Deskmate team (Kosuke Ikeda and Kensuke Yamasaki, hereinafter the "Service Provider") handles user information in the mobile app "Deskmate" (iOS / Android, hereinafter the "Application").
Information We Collect
1. Information Collected Automatically
While you use the Application, the following information may be collected automatically:
App usage (features used, screens viewed, date and time of actions, usage time, etc.)
Device and OS information (device type, OS version, language and region settings, etc.)
IP address (obtained when communicating with third-party services)
Approximate region derived from your IP address
Advertising ID (Android only)
This information is used solely to analyze app usage and is not used to deliver advertising.
2. Information Collected When You Create an Account
If you create an account with "Sign in with Apple" or "Sign in with Google" (Android supports "Sign in with Google" only), we collect the following information through Firebase Authentication:
User ID (issued by Firebase Authentication)
Email address (if you choose "Hide My Email" with Apple, the relay address issued by Apple)
We use this information so that your purchased plan and existing-user benefits carry over after changing devices or reinstalling.
In addition, if you claim the existing-user benefit, we store the following information on Amazon Web Services (AWS) servers to determine whether you are eligible for the benefit:
User ID
The OS you use (iOS / Android)
The date and time the benefit was registered
Creating an account is optional. You can purchase a paid plan without an account; creating one lets you keep your plan after changing devices or reinstalling. An account is required to claim existing-user benefits.
3. Purchase Information
We use RevenueCat (a service that manages subscription purchase status) to manage purchases, and send the following information to RevenueCat:
Subscription status (the plan purchased, expiration date, free trial usage, purchase history, etc.)
An anonymous ID issued by RevenueCat (linked to your account's user ID when you sign in)
Device information (OS type and version, device type, app version, etc.)
We use this information to verify your purchase status and to restore your plan after changing devices or reinstalling. Payment details such as credit card numbers are processed by the App Store / Google Play, and the Service Provider never receives them.
4. Information You Provide When Contacting Us
If you contact us through the in-app contact form or by email, we collect your email address, the subject, and the content of your inquiry.
5. Information Kept Only on Your Device
The following information is stored only on your device and is never sent to the Service Provider or any third party:
The apps you select to block with Deep Focus
Settings for timers, moods, ambient sounds, and more
Deep Focus works using the Screen Time API on iOS and the Accessibility Service on Android. On Android, the Accessibility Service is used solely to determine whether a launched app is on your block list. It does not collect or transmit screen content or anything you type.
How We Use Information
We use the information we collect for the following purposes:
To provide the Application, improve its features, and fix bugs
To provide paid plans, verify purchase status, and restore purchases
To carry over your purchased plan and existing-user benefits after changing devices or reinstalling
To determine eligibility for existing-user benefits
To respond to inquiries and send important notices
For statistical analysis for feature development and marketing (performed in a way that does not identify individuals)
