Maskan — Private AI Chat Effective date: May 25, 2026 Last updated: June 5, 2026
Maskan is a privacy-first, open-source Android app that lets you chat with AI providers using your own API keys (BYOK — Bring Your Own Key). This privacy policy explains what data Maskan handles, how it is stored, and what leaves your device.
Maskan has no backend server, no user accounts, no analytics, no telemetry, no crash reporting, and no advertising. The full source code is publicly available under the GPL-3.0 license at github.com/humammalhas/maskan.
All of the following data is stored locally on your device and is never transmitted to the developer or any third party:
When you send a chat message, Maskan transmits the following to the AI provider you have configured:
You choose which provider to use. Maskan supports 12 providers: DeepSeek, OpenAI, Anthropic Claude, Google Gemini, Groq, Together AI, Mistral, Venice AI, OpenRouter, Ollama, LM Studio, and custom URL endpoints. No data is sent to any provider until you configure an API key and actively send a message.
Maskan does not control how providers handle your data. Each provider has its own privacy policy and terms of service. You are responsible for reviewing and accepting those terms when you obtain your API key. Maskan acts solely as a client — it sends your messages to the provider you selected and displays the response.
The app’s network access is restricted via Android’s network security configuration to only the hosts associated with providers you have enabled.
Maskan requests two Android permissions:
Voice narration (text-to-speech) uses whichever text-to-speech engine you have set as your device’s default; Maskan sends it only the on-screen reply text to be spoken aloud, locally on your device.
Maskan includes an optional block screenshots setting (off by default). When enabled, it sets the Android FLAG_SECURE flag on the app window, which prevents screenshots and screen recording of the app and hides it from the recent-apps preview. This is a local security control and involves no data collection.

All data is stored on your device. You can delete it at any time by:
There is no server-side data to delete because Maskan has no server.
Maskan is not directed at children under 13. The app does not knowingly collect personal information from children. Since Maskan stores all data locally and collects no data from users, no special data handling for children is required.
If this privacy policy is updated, the changes will be posted to this page with an updated date. Since Maskan is open source, all changes are tracked in the project’s version control history.
