Short version:We don't collect your personal data. Your information never leaves your device. No accounts, no servers, no tracking.
1. Overview
ThreeSunnyDev (“we”, “our”, or “us”) builds mobile applications for Android. This Privacy Policy applies to all apps published by ThreeSunnyDev, including Expense King.
We are committed to privacy by design. Our apps are built to function entirely without collecting, transmitting, or storing any personal data on external servers.
2. Data We Do Not Collect
We do not collect, process, or store any of the following:
- Names, email addresses, or any personal identifiers
- Location data
- Device identifiers (beyond what advertising SDKs may use — see section 5)
- Usage analytics or behavioral data
- Financial data or transaction history
- Any data that would identify you as an individual
3. Local Data Storage
All data you enter into our apps (such as expenses, wallet names, and categories in Expense King) is stored locally on your device using SQLite, a standard local database format.
This data never leaves your device. We have no access to it. If you uninstall the app, this data is deleted.
4. No Internet Connection Required
Our apps are designed to work fully offline. No account creation is required. There is no login, no registration, and no backend server associated with your usage of the app.
5. Advertising (AdMob)
Our apps may display ads served by Google AdMob. We use non-personalized ads, which means AdMob does not build a user profile or use your personal data for ad targeting.
Even with non-personalized ads, AdMob may collect certain device information (such as an advertising ID or IP address) as part of ad delivery. This is governed by Google's own privacy policy. We do not receive or control this data.
For more information, see Google's Privacy Policy.
6. Children's Privacy
Our apps are not directed at children under the age of 13. We do not knowingly collect any information from children. If you believe a child has provided personal information through our app, please contact us and we will take appropriate action.
7. Changes to This Policy
We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated date. We encourage you to review this policy periodically. Continued use of our apps after changes constitutes acceptance of the updated policy.
