Shikhao - শিখাও (com.abir.banglashikhi)

Shikhao is a fully offline app for learning to write Bangla letters and digits. It does not request the Android internet permission and cannot send data anywhere, on or off the device.

• No personal data is collected, stored, or shared. There are no accounts, sign-in, or user profiles.
• Handwriting you draw is processed entirely on-device by a local machine-learning model and is never saved or transmitted.
• Your progress (stars earned per lesson) is saved only in local app storage on your device and is deleted if you uninstall the app.
• The app contains no ads, no analytics, and no third-party SDKs.

Sciniverse: Science Lab (com.abir.sciniverse)

Sciniverse is an interactive physics, mathematics and chemistry lab. It works entirely offline: every simulation, sound and voice tutorial is stored inside the app. It does not request the Android internet permission and cannot send data anywhere, on or off the device. It requests no other device permissions either (no location, contacts, camera, microphone or storage).

• No personal data is collected, stored, or shared. There are no accounts, sign-in, or user profiles.
• Voice tutorials use the text-to-speech engine already installed on your device. The text is spoken on your device and is not sent to me.
• Your settings (for example voice speed and whether to play the opening animation) are saved only in local app storage on your device and are deleted if you uninstall the app.
• The app contains no ads, no analytics, and no third-party SDKs.

Dice Guess (com.abir.diceguess)

Dice Guess is a multiplayer dice-prediction game. It uses the following third-party services:

• Firebase Authentication — to create your player account (e.g. email or a linked sign-in provider).
• Firebase Realtime Database — to store your game state, scores, and matchmaking data for local and online multiplayer.
• Google AdMob — to display ads. AdMob may collect device and advertising identifiers under its own privacy policy: policies.google.com/privacy.

This data is used only to operate the game (accounts, scores, multiplayer, ad-supported free access) and is not sold. You can request deletion of your account data at any time using the contact details below.
