Memo Screen
Offline Notepad
Effective Date: June 5, 2026

Your Thoughts
Remain Yours Alone.

Memo Screen does not collect, store, upload, or share your data. Everything you write stays strictly encrypted on your physical device. No trackers, no clouds, no analytics.

Zero Cloud Collection

We have no servers, no user accounts, and no cloud integration. There is no central database where your data can leak.

100% Offline Functionality

The app works completely without internet access. All note processing, rendering, and storage occur entirely locally.

No Trackers or Ads

We do not partner with third-party ad networks or include commercial tracking SDKs. Your app experience is purely functional.

Information Overview

This Privacy Policy governs your use of the mobile application Memo Screen (the "Application"), which was created as a fully offline note-taking and todo app.

Our philosophy is simple: your thoughts, plans, and memos are private information and should never leave your device. Therefore, the Application is designed to operate completely without cloud databases, web servers, or external network requests.

Key Takeaway

We do not collect any personal data, email addresses, phone numbers, unique device identifiers, IP addresses, geolocations, note contents, or todo items.

2

Local Storage & Security

All data created within the Application is stored in the device's internal sandbox environment.

  • Zustand & MMKV: We utilize the ultra-fast, local key-value store library react-native-mmkv to save your note structures and settings.
  • No Cloud Storage: We do not offer or support backup to remote servers, Firebase, or external databases. If you uninstall the Application, your local notes will be deleted permanently by the operating system.
  • Offline Wallpaper Generation: The Live Wallpaper feature operates using a local HTML5/React Native Canvas module. It renders your text onto a temporary image file stored within the Application's private storage path and sends it to the OS.

Device Permissions

To offer specific native features, the Application requires access to certain functions on your device. These permissions are only executed locally:

Set Wallpaper Permission (SET_WALLPAPER)

Required on Android to programmatically update your phone's background screen with the note that you have marked as your "Live Wallpaper".

Internal Storage Access

Used strictly to write temporary, offline-generated PNG note backgrounds to your app directory so the Android WallpaperManager can consume the file and apply it.

4

Third-Party Libraries

The application leverages several reputable open-source libraries to deliver features without compromising user privacy. None of these libraries have access to network calls through our app, nor do they transmit data externally:

react-native-canvas

Generates high-definition canvas renderings of note layouts locally.

react-native-mmkv

Fast local storage. All items stay contained in the encrypted app sandbox.

react-native-reanimated

Enables smooth layout transitions and visual feedback entirely on-device.

Custom Android Modules

Direct system APIs written natively in Kotlin to communicate with Android's WallpaperManager.

5

Children's Privacy

Since the Application does not collect, record, process, or transmit any data whatsoever, it is safe for and compliant with regulations regarding children's privacy, including COPPA (Children's Online Privacy Protection Act) and GDPR.

6

Policy Changes

We reserve the right to modify this privacy policy at any time. However, our stance against cloud data collection is absolute. Any future updates to the software will maintain strict adherence to local sandboxed storage and absolute user-controlled data guidelines. We recommend reviewing this page periodically to remain updated on compliance.
