Privacy policy

Last updated: September 2026. Applies to Lite Mind for Android (com.lite_mind).

Lite Mind is a hobby project, not a company. This policy is short because there is very little to describe. The app has no server, no account system and no analytics, so there is nowhere for your data to go.

The short version

The language model runs on your phone. Your messages are answered on the device and are never transmitted anywhere. I cannot read your conversations, and I have no way to reach them.

What stays on your device

• Your conversations. Chat history is written to the app's own private storage on the phone.
• Your settings. Model choice and preferences, stored the same way.
• The model files you download, kept in the app's own files directory so they go when the app goes.

All of it is removed when you uninstall Lite Mind, and you can clear conversations from inside the app at any time.

When the app uses the network

Lite Mind needs the internet for two things. Neither one involves the content of your chats.

• Downloading a model. Chat models are fetched over HTTPS from Hugging Face, and the voice model the first time you tap the microphone. These are plain file downloads. Nothing about you is sent with them beyond what any download requires, and Hugging Face's own privacy policy covers their side of the request.
• App updates. The app asks Google Play whether a newer version exists, using Play's update service.

Once a model is on your phone the app works with no connection at all. Answering a message never touches the network.

Microphone and dictation

If you use voice typing, the app asks for microphone permission at the moment you tap the microphone, never at launch. The recording is turned into text on the phone by whisper.cpp, placed in the message box for you to edit, and then discarded. No audio is uploaded and no recording is kept.

You can decline the permission and keep using the app by typing, or withdraw it later in Android's app settings.

Permissions the app asks for

• Internet, to download models and check for updates.
• Microphone, only if you choose to dictate, and only at that tap.

Models are saved in the private directory Android grants every app, so no storage permission is requested. The app asks for no access to your camera, contacts, location or files.

Distribution through Google Play

The app itself sends Google nothing about your use of it. Google Play, as the store that distributes it, collects its own install and stability statistics under Google's privacy policy. That happens outside the app and outside my control. Any crash data I see through the Play Console is aggregated and contains no conversation content.

Children

Because nothing is collected, there is no personal information of any user, of any age, for this app to misuse. Do note that answers come from a small language model and can be wrong or unexpected, so younger users are best supervised.

Changes to this policy

If the app ever starts doing something this page does not describe, the page will be updated before that version ships, and the date at the top will change with it.

Contact

Questions about privacy, or anything else, go to [email protected]. It is one person answering, so a reply may take a little while.

If you would rather check this than take my word for it, you can. Once a model has downloaded, put the phone in aeroplane mode and carry on chatting. The replies keep coming because the model is on the device, and Android's data usage screen will show the app sending nothing.
