♿ Accessibility Service Usage
This app uses the Android AccessibilityService API ONLY for the long screenshot feature.
Specifically, it is used to:
Automatically scroll the screen vertically during long screenshot capture
Stitch multiple screen sections into a single complete image
This app does NOT:
Collect, read, or store personal or sensitive data
Record keystrokes, passwords, or user input
Monitor user behavior or screen content
Perform automated actions unrelated to long screenshots
Transmit accessibility data to external servers
The accessibility service is enabled only with explicit user consent and is active only while the long screenshot feature is in use.

🔐 Privacy First
Screen Markup respects user privacy.
All features operate locally on the device, and no personal data is collected or transmitted without permission.
