Last Updated: January 3, 2026

This Privacy Policy describes how KillLine ("we", "our", or "the app") handles your information. By using KillLine, you agree to the practices described in this policy.

1. Information We Do NOT Collect

KillLine is committed to protecting your privacy. We want to be clear about what we don't do:

  • No Personal Information: We do not collect your name, email, phone number, or any other personal identifiers.
  • No Financial Data: Your income, expenses, savings, and all financial information remain exclusively on your device.
  • No Usage Analytics: We do not track how you use the app, which features you access, or how often you use it.
  • No Location Data: We do not access or collect your location information.
  • No Device Information: We do not collect information about your device, operating system, or unique identifiers.
  • No Third-Party Tracking: We do not use any third-party analytics, advertising, or tracking services.

2. How Your Data is Stored

All data you enter into KillLine is stored locally on your device using Apple's Core Data framework:

  • Local Storage Only: Your financial profiles, simulation results, and settings are stored exclusively on your iPhone or iPad.
  • No Cloud Sync: We do not sync your data to any cloud service or remote server.
  • No Network Requests: The app does not make any network connections or internet requests.
  • Complete Control: You have full control over your data and can delete it at any time by deleting the app.

3. Permissions

KillLine may request the following optional permissions:

Photo Library Access (Optional)

If you choose to save simulation result images to your photo library, the app will request permission to access your photos. This permission is:

  • Completely optional - you can use all app features without granting this permission
  • Only used when you explicitly tap the "Save Image" button
  • Only grants write access to save images you create
  • Does not allow the app to read or access your existing photos

4. Data Security

Your data security is ensured through:

  • iOS Sandbox: The app operates within Apple's secure iOS sandbox environment.
  • Encrypted Storage: Data is protected by iOS device encryption when your device is locked.
  • No Transmission: Since data never leaves your device, there's no risk of interception during transmission.
  • No Servers: We don't operate any servers that could be compromised or hacked.

5. Children's Privacy

KillLine does not knowingly collect any information from anyone, including children under 13. The app is designed for general audiences and does not contain age-restricted content.

6. Data Sharing

We do not share any data with third parties because we don't collect any data in the first place. Your information stays on your device and is never transmitted to us or anyone else.

7. Your Rights

Since all data is stored locally on your device, you have complete control:

  • Access: You can access all your data within the app at any time.
  • Modify: You can edit or update your financial profiles and settings whenever you want.
  • Delete: You can delete individual records within the app or remove all data by deleting the app.
  • Export: You can export simulation results as images to share or save externally.

8. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be reflected in the app and on this page with an updated "Last Updated" date. We encourage you to review this policy periodically.

If we make any material changes to how we handle user data (which would require us to start collecting data), we will notify users through the app and obtain consent where required by law.

9. International Users

KillLine can be used anywhere in the world. Since all data processing happens locally on your device, there are no international data transfers or jurisdictional concerns.
