Privacy Policy (LifeSpan)

This Privacy Policy ("Policy") describes how Hideichi Apps ("we," "our," or "us") collects, uses, and protects user information in connection with the Android application "LifeSpan" ("the App").

We respect your privacy and are committed to protecting it in accordance with applicable laws and regulations concerning personal information and data protection.

This Policy is available at all times from the App's page on the Google Play Store and within the App itself (Settings > Privacy Policy).

1. Information We Collect and How We Use It

(1) Information Provided by Users

The App allows users to manually enter "LifeSpan" records (such as titles, target dates, or life events). This information is stored locally on your device only and is not transmitted to our servers or to any third parties.

(2) Automatically Collected Information

We use Firebase Analytics and Firebase Crashlytics to help us understand app usage trends and to improve stability and performance. These tools may automatically collect information such as:

Device model and operating system
App version and usage duration
Crash logs and error data
Aggregated, anonymized usage statistics

All data collected through Firebase services is non-personally identifiable and is used solely for app improvement purposes.

2. Data Sharing and Disclosure

We do not share, sell, or disclose any personal information to third parties. However, anonymized analytics and crash data collected via Firebase may be processed by Google LLC as part of Firebase's standard service operation, in accordance with Google's Privacy Policy.

3. Data Storage and Retention

All user-entered data (LifeSpan records) is stored only on the user's device and is deleted when the app is uninstalled.
Analytical data collected via Firebase is stored on Google's servers and retained for a limited period as defined by Firebase's internal policies.

4. Security

We take reasonable measures to protect user data from unauthorized access, loss, misuse, or alteration. However, please note that no method of electronic storage or transmission over the Internet is 100% secure.

5. User Rights

Because the App does not collect or store personally identifiable information, users are not required to submit data deletion or access requests. You can permanently delete all locally stored data by uninstalling the App.

6. Changes to This Policy

We may update this Privacy Policy from time to time. Any significant changes will be communicated via the App or on the Google Play Store page. The updated version will take effect as of the "Effective Date" shown below.
