Privacy Policy
Our commitment to your privacy isn't just a policy—it's built into our architecture.
Last updated: January 15, 2025
Zero Data Collection
Billington doesn't collect, store, or transmit any personal data. Period.
About Billington
Billington is a bill-splitting application developed by Kruski Ko. The app is designed to help users divide restaurant bills and expenses among friends while maintaining complete privacy.
This privacy policy explains our data practices for the Billington iOS application and this website.
Data Collection Practices
What We DON'T Collect
- Personal information (names, emails, phone numbers)
- Financial data or payment information
- Location data or GPS coordinates
- Device identifiers or advertising IDs
- Usage analytics or behavioral data
- Contact lists or social media connections
What We DO Collect
Absolutely nothing. Billington operates entirely offline.
How Your Data is Handled
Local Storage Only
All bill data is stored exclusively on your device using SQLite database. No information ever leaves your phone.
Optional Sharing
When you share bill summaries, only the text you choose to share is sent via your device's native sharing system.
Third-Party Services
Billington does not integrate with any third-party services, analytics platforms, or advertising networks. The app operates in complete isolation.
Device Permissions
Billington requests minimal device permissions:
- System Share Sheet
Access to your device's native sharing functionality to send bill summaries via text, email, or other messaging apps.
That's it. No camera, contacts, location, or network permissions are requested or used.
Children's Privacy (COPPA Compliance)
Since Billington collects no personal information whatsoever, it is inherently compliant with the Children's Online Privacy Protection Act (COPPA). The app can be safely used by children under 13 without parental consent requirements.
We do not knowingly collect any information from children or adults.
Your Privacy Rights
Under various privacy laws (GDPR, CCPA, etc.), you typically have rights regarding your personal data. However, since Billington collects no personal data:
Data Security
Your bill data is secured by your device's built-in security features, including:
- iOS app sandboxing and security framework
- Device-level encryption when enabled
- No network transmission means no interception risk
Since no data leaves your device, you maintain complete control over your information.
Policy Updates
We may update this privacy policy from time to time. Any changes will be posted on this page with an updated "Last updated" date.
Given that our core privacy principles are built into the app's architecture, any changes are likely to be clarifications rather than changes to our data practices.
