Privacy Policy

1. Introduction

NoTransaction ("we", "our", "the app") is a balance-based personal finance app. This Privacy Policy explains how we handle information when you use NoTransaction on Android or iOS.

2. Data Storage — Local-First by Design

All your financial data — including balances, accounts, history, and every single financial figure — is stored exclusively on your device in an on-device local database (SQLite). Your financial data never leaves your device. This is the core differentiator and founding principle of NoTransaction, not a temporary limitation.

• No user accounts: You do not need to register, create an account, or log in to use the app.
• No mandatory cloud sync: There are no company servers syncing, transmitting, or holding your financial figures.
• No remote copies: We do not operate servers that receive or store your accounts, balances, or financial records.
• If you uninstall the app, your local data is permanently deleted unless you create a backup beforehand.

3. Information We Collect

We collect minimal, non-personal data through third-party services solely to maintain stability and understand aggregate usage patterns:

This collected data is anonymous and does not include your financial numbers, account names, or balances. This list represents the complete set of external data collection used by the app.

4. What We Do NOT Collect

We do not collect, request, or store:

• Your name, email address, phone number, or personal identity (unless you explicitly email support)
• Your account names, balances, history, or any financial figures
• Your location or GPS coordinates
• Your contacts, photos, or file library (except screenshots you explicitly attach to bug reports — see section 8)
• Payment card details, bank credentials, or payment methods (all purchases are handled entirely by Google Play — see section 6)

5. Exchange Rates

All currency exchange rates in NoTransaction are manually entered and managed directly by you. They are stored strictly locally on your device. The app does not call, connect to, or query any external exchange rate services or third-party financial APIs.

6. Payments & In-App Purchases

NoTransaction offers optional Premium features available through in-app purchases. All purchases are processed entirely by Google Play Billing.

• NoTransaction does not receive, process, or store any of your payment card numbers, bank details, or payment methods.
• All payment transactions and billing information are handled securely by Google Play under Google's Privacy Policy.
• Purchase entitlements are verified on your device via Google Play Billing APIs.

7. Refunds

Refunds for in-app purchases are handled in accordance with Google Play's standard refund policies.

• Google Play allows users to request an automated refund within the first 48 hours of purchase.
• You can submit a refund request directly on Google Play's refund page.
• If you have any questions or require assistance, you may contact us at letansang.work@gmail.com.

8. Bug Reports

When you submit a bug report through the app, your text description and any attached image are uploaded to Firebase Storage to assist our development team in troubleshooting issues.

• Optional Attachments: Attaching an image is entirely optional — you are never required to provide a screenshot to submit a bug report.
• Retention Period: Bug reports and attached screenshots are retained for 90 days solely for debugging and resolving issues, after which they are permanently deleted.
• Deletion Requests: You can request the deletion of your submitted bug report data and attached images at any time by emailing us at letansang.work@gmail.com.

9. Backup & Automatic Backup

NoTransaction provides backup features to safeguard your financial records:

• User-Selected Directory: The automatic backup feature and manual export save your backup file directly into a directory chosen solely by you (such as your personal Google Drive, iCloud, or a folder on your device).
• Zero Server Access: We do not keep copies of your backup files, and we have no ability to access or view your chosen backup directory or files.
• Full User Control: You maintain complete ownership and control over your exported backup files.

10. User Rights & Data Control

You maintain complete authority over your data at all times:

• Delete all data in-app: You can permanently wipe all local accounts, balances, and history directly inside the app at any time via Settings.
• Export data: You can export your full data history to a JSON file at any time for personal backup or migration.
• Request deletion of bug reports: You can request immediate removal of any bug reports or screenshots you submitted by contacting letansang.work@gmail.com.

11. Third-Party Services

We use the following third-party services. Their own privacy policies apply:

• Firebase (Google) — Analytics, Crashlytics, Remote Config, Cloud Messaging, Storage
• Google Play — In-app purchases and billing

12. Children's Privacy

NoTransaction is not directed to children under 13. We do not knowingly collect any personally identifiable information from children. If you believe a child has provided us with personal data, please contact us.

13. Data Security

Since your financial data is stored locally on your device, its security depends on your device's security measures (screen lock, biometrics, hardware encryption, etc.). We recommend keeping your operating system and device software up to date.

14. Changes to This Policy

We may update this Privacy Policy from time to time as we add new features. Changes will be posted on this page with an updated "Last updated" date. Continued use of the app after changes constitutes acceptance of the revised policy.
