Introduction
Welcome to Kakeibo.
Kakeibo is a personal finance journal inspired by the Japanese Kakeibo method. We value your privacy and are committed to protecting your information.
This Privacy Policy explains what information Kakeibo collects, how it is used, and your rights regarding your data.
By using Kakeibo, you agree to this Privacy Policy.

This information is stored locally on your device and is used only to provide the app's functionality.
Offline-First Data Storage
Kakeibo is designed as an offline-first application.
Your financial records remain stored locally on your device. The current version of the app does not upload your financial data to our servers.
Automatically Collected Information
To improve the reliability and stability of the application, Kakeibo uses Firebase Crashlytics.
Firebase Crashlytics may automatically collect limited technical information, including:
- Crash reports
- Device model
- Operating system version
- App version
- Installation identifiers
- Technical diagnostic information related to application crashes
Crash reports do not include your personal financial records, such as income, expenses, budgets, savings goals, journal entries, or reflections.
How We Use Information
The information stored within the app is used to:
- Record expenses
- Calculate budgets
- Track savings goals
- Display financial summaries
- Generate spending insights
- Improve the overall user experience
- Diagnose and fix application crashes
Data Sharing
We do not sell, rent, or share your personal financial information with third parties.
Technical crash reports collected through Firebase Crashlytics are processed by Google solely for the purpose of identifying and fixing application errors.

Permissions
The current version of Kakeibo does not request access to device permissions such as:
- Camera
- Photos and Media
- Location
- Contacts
- Microphone
- Notifications
If future versions introduce features requiring additional permissions, this Privacy Policy will be updated before those features become available.
Data Security
We take reasonable technical and organizational measures to protect your information.
Although no method of electronic storage is completely secure, we strive to safeguard your information using industry best practices.
Children's Privacy
Kakeibo is not intended for children under the age of 13.
We do not knowingly collect personal information from children.
Your Rights
Because your financial information is stored locally on your device, you remain in control of your data.
You may delete your records at any time by removing them within the app or by clearing the application's local data.

We may update this Privacy Policy from time to time.
When changes are made, the updated version will include a revised Effective Date.
