Data Storage
Local Storage Only
Text Processing
All text analysis is performed locally on your device. Your text never leaves your device.
No Server Storage
Unlike our website version, this App does not store your text on any servers, which means:
- You cannot share analysis results with others through the App

Data Retention
On Your Device
Any data stored locally on your device (such as app preferences or cached data) remains on your device until you uninstall the App or clear the App's data.
Analytics Data
Analytics data collected by PostHog is retained according to PostHog's data retention policies. Please refer to PostHog's privacy policy for details. This data does not include your text content.
Data Sharing and Disclosure
We do not share, sell, or disclose your text content to anyone because we do not collect it. The limited technical information we may collect (if any) is used solely for the purposes described in this Privacy Policy.
We may share non-personal, aggregated analytics data (that does not include your text) only in the following circumstances:
Service Providers
We may share aggregated analytics with service providers who help us improve the App, such as:
- PostHog (analytics services)
- Crash reporting services
These service providers are contractually obligated to protect your information and use it only for the purposes we specify. These providers do not have access to your text content.

If you have questions about the App or our data practices, please contact us at: [email protected]
Device Permissions
Our App may request certain permissions on your device to function properly. We only request permissions that are necessary for the App's functionality:
Internet Permission (if applicable)
May be used for analytics, crash reporting, or app updates. This permission does not allow us to access your text content.
Storage Permission (if applicable)
May be used to save app preferences or cache data locally on your device.
We do not request unnecessary permissions, and you can revoke permissions at any time through your device settings.
Data Security
Since all text processing occurs locally on your device, your text content is protected by your device's security measures. We implement appropriate security measures for any technical data we may collect. However, no method of electronic storage is 100% secure, and we cannot guarantee absolute security.
Third-Party Services
Our App uses PostHog for analytics services. PostHog may collect limited technical information such as:
- Device and app usage statistics
- Feature usage patterns
- App performance metrics
- Crash and error reports
However, PostHog does not have access to your text content because it is processed entirely on your device. PostHog only receives anonymized, aggregated analytics data that does not include any personal information or text content.

Key Difference from Website Version
Important: This Android App differs from our website version in a crucial way:
- Website: Stores text anonymously on servers for sharing functionality (with 1-year retention)
- Android App: Processes text entirely on your device with no server storage or sharing capability
This means your text in the Android App is more private and secure, as it never leaves your device.
This Privacy Policy is effective as of the date stated above and applies to all users of the Flesch-Kincaid Calculator Android App.
