Overview
Hallucinatron ("we", "our", or "the App") is an Android application that provides a chat interface for OpenAI-compatible AI language models. This Privacy Policy describes how the App handles your data.
The App operates entirely on your device. We do not operate servers that collect, store, or process your personal data.
1. Data Stored Locally on Your Device
All data is stored locally using Room SQLite database and DataStore Preferences on your device. This includes:
- AI Model configurations — names, base URLs, API keys, temperature, system prompts, max tokens, timeouts, and per-token pricing you configure.
- Conversations — titles, tags, pinned status, per-conversation system prompts, and timestamps.
- Messages — your messages and AI-generated responses, including thinking/reasoning blocks and token usage metadata.
- Prompt templates — reusable text snippets you create.
- App settings — default temperature, max tokens, system prompt, theme preference, and onboarding status.
2. Data Sent to Remote Servers
When you send a message, the App transmits the following to the AI endpoint you configure (e.g., a local server or a third-party provider like OpenAI):
- Your message content and full conversation history
- The model name, temperature, and max tokens settings
- Your API key (sent as a Bearer token for authentication)
The App sends data only to the base URL you explicitly configure. We do not control, access, or store any data transmitted to these third-party endpoints. You should review the privacy policies of any AI providers you use.
3. Permissions
The App requests the following Android permissions:
- INTERNET — required to communicate with your configured AI API endpoint.
- POST_NOTIFICATIONS — used to display a notification when a response completes while the App is in the background. Tapping the notification opens the relevant conversation.
Data We Do Not Collect
- No analytics or usage telemetry
- No crash reporting services
- No advertising identifiers
- No account or authentication data
- No location, contacts, camera, microphone, or sensor data
No Third-Party SDKs
The App does not include any third-party analytics, advertising, crash reporting, or tracking SDKs (such as Firebase, Crashlytics, Adjust, or similar). All code runs locally; no SDK transmits data on the App's behalf.
4. Data Security
- Your API keys are stored locally in the Room database. Protect your device to protect your keys.
- All data remains on your device. We have no servers and cannot access your data.
- The App does not back up data to cloud services.
Third-Party Services
The App connects to AI API endpoints you configure. Data transmitted to these services is governed by their respective privacy policies, not this one. The App itself does not integrate with any third-party analytics, advertising, or crash reporting SDKs.
5. Data Deletion
All data stored by the App can be deleted at any time:
- Delete individual conversations via swipe-to-delete in the chat list.
- Uninstalling the App removes all locally stored data.
Children's Privacy
The App does not target children under 13 and does not knowingly collect data from children.
6. Changes & Contact
We may update this Privacy Policy from time to time. Changes will be reflected in the "Last updated" date at the top of this page.
