Privacy Policy
Effective Date: September 29, 2026 | Last Revised: 2026
This Privacy Policy describes how Hachi Studio LLC ("we", "us", or "our"), incorporated in Colorado, USA, collects, uses, protects, and discloses personal information across our mobile applications, software tools, website, and customer service operations. By downloading, accessing, or using any application distributed by Hachi Studio LLC on the Apple App Store or Google Play Store, you acknowledge and agree to the policies outlined herein.
1 Information We Collect (Data Minimization Principle)
We adhere strictly to the principle of data minimization and do not harvest unnecessary user records:
- Diagnostic & Crash Telemetry: Anonymized device metrics (e.g., OS version, device architecture, crash stack traces) collected solely to diagnose fatal exceptions and ensure release stability.
-
User Communications: If you voluntarily contact our customer support desk (
support@hachi-studio-llc.com), we retain your email address, provided name, and issue description to facilitate problem resolution. - On-Device Local Data: User-created content (e.g. notes, habit tracking, timer logs) is stored in the app's local sandbox storage and is never uploaded to remote servers without explicit user request.
2 Third-Party Services & Advertising Providers
Depending on application configuration and monetization tier (such as free or ad-supported releases), applications may integrate trusted third-party developer toolkits:
- Google AdMob & Play Services: For contextual or non-personalized advertisements. Governed by Google Privacy & Terms. Users can opt out of personalized ads via device OS settings.
- Apple App Tracking Transparency (ATT): For iOS 14.5+ releases, applications request explicit user authorization prior to accessing the Advertising Identifier (IDFA).
- Firebase Crashlytics / Google Analytics: Used strictly for crash triage, performance logging, and ANR (Application Not Responding) minimization.
3 Purpose & Use of Information
Collected technical data is utilized strictly to:
- Deliver, optimize, and maintain mobile software stability across diverse device types;
- Respond to bug reports, feature suggestions, and App Store review inquiries;
- Fulfill statutory accounting, tax, and legal requirements;
- Protect systems against malicious attempts, exploitation, or abuse.
