This Privacy Policy explains how DevStudio ("we", "us", "our") collects, uses, and protects information in connection with the mobile application Expense Tracker-Money Manager (the "App"). By installing or using the App, you agree to the practices described here.
The App is designed to be private-first. The financial data you enter — transactions, categories, books, and budgets — is stored locally on your device and is not transmitted to us or sold to anyone. Some limited data is processed by Google/Firebase services to keep the App stable, to enable optional sign-in, and to process optional subscription purchases, as described below.
| Category | What it includes | How it is handled |
|---|---|---|
| Financial & transaction data | Expenses, income, investments, categories, books, budgets, notes you enter | Stored locally on your device only. Never uploaded to our servers. |
| Account data (optional) | Email address, display name, and profile identifier from your Google account | Collected only if you choose to sign in with Google. Handled via Firebase Authentication. |
| Crash & diagnostic data | Crash logs, stack traces, device model, OS version, app version | Collected via Firebase Crashlytics to diagnose and fix crashes. |
| Usage & analytics data | App interaction events, feature usage, approximate session data, app-instance identifiers | Collected via Firebase Analytics to understand how the App is used and improve it. |
| Purchase data | Subscription status and purchase tokens for Pro features | Payments are processed by Google Play Billing. We do not receive or store your card or payment details — only whether an entitlement is active. |
We do not sell your personal data, and we do not use your financial transaction data for advertising.
We share limited data only with the service providers required to operate the App:
We do not sell or rent your personal information to third parties.
Your financial data lives on your device; uninstalling the App or clearing its data removes it. You can also delete individual entries within the App at any time.
If you signed in with Google, you can request deletion of your account and any associated account data by emailing us at the address below. Diagnostic and analytics data collected by Firebase is retained according to Google's retention policies.
We take reasonable technical measures to protect your information. Financial data remains on your device, and data in transit to Google/Firebase services is encrypted. No method of storage or transmission is completely secure, and we cannot guarantee absolute security.
The App is not directed to children under 13, and we do not knowingly collect personal information from children. If you believe a child has provided us information, contact us and we will delete it.
We may update this Privacy Policy from time to time. Material changes will be reflected by updating the "Last updated" date above. Continued use of the App after changes constitutes acceptance of the revised policy.
