Privacy Policy for DoomsDay Mobile App
1. Introduction
DoomsDay is an experimental, educational mobile application that provides an offline AI assistant using on-device language models. This Privacy Policy explains how the app treats your data when you use it. Important: DoomsDay is designed for privacy. It does not collect, use, or share personal information for advertising, analytics, or tracking. AI processing runs locally on your device.
2. Scope and Applicability
This policy applies to the DoomsDay mobile application (“the App”) distributed through the Google Play Store. The App is experimental software intended for educational and informational purposes.
3. Data We Do NOT Collect
DoomsDay does NOT:
- Collect personal information (name, email, phone number, etc.)
- Collect usage or analytics data
- Use advertising or third-party ad networks
- Track your activity
- Sell or share data with third parties
- Use crash reporting or telemetry services that send data externally
4. Data Stored Locally on Your Device
The App stores data only on your device for core functionality:
| Data Type | Purpose | Storage Location |
|---|---|---|
| Conversation history | Preserve chat sessions and context | Local SQLite database |
| Chat messages | Maintain context for the AI assistant | Local SQLite database |
| Session metadata | Manage multiple chat sessions | Local SQLite database |
| User actions (e.g., scenario selections) | Provide context within a session | Local SQLite database |
| Downloaded AI models | Enable offline AI inference | App files directory |
| App settings and preferences | Remember your choices | Local storage |
All of this data stays on your device. It is not transmitted to our servers or any external services.
5. Permissions and Their Use
The App requests the following permissions and uses them only for the listed purposes:
| Permission | Purpose |
|---|---|
| Internet | Optional: Downloading AI models from third-party sources (e.g., Hugging Face) when you choose to add models. Opening external links (e.g., website, support) when you tap them. |
| Storage / Media | Optional: File picker access for images, videos, and audio you choose to attach. Saving exported conversations to your Downloads folder. |
| Wake Lock | Keeping the screen on during AI generation so the process is not interrupted. |
The App can function offline after models are installed. Internet is used only for optional model downloads and for opening external links you choose.
6. Android Backup
The App may participate in Android’s built-in backup (e.g., to your Google account). Any backup is controlled by Google and your device settings. Backup data is not sent to the developer.
7. Third-Party Services
- Model downloads: If you download AI models, files are fetched from third-party sources (e.g., Hugging Face). The App downloads model files only; no personal data is shared. Please review those providers’ own privacy policies.
- External links: The App may include links to websites (e.g., doomsday.media) or support pages. Visiting these sites is optional and subject to those sites’ privacy policies.
8. Children’s Privacy
The App is not intended for children under 13. We do not knowingly collect personal information from children. If you believe a child has provided personal information through the App, contact us so it can be removed.
9. Experimental and Educational Use
DoomsDay is experimental software provided for educational and informational purposes. Content generated by the AI may be inaccurate, incomplete, or misleading. Do not rely on it as a sole source of truth; always verify important information independently.
10. Data Security
- Data is stored only on your device.
- No personal data is transmitted to our servers.
- We do not have access to your conversations or other local data.
- You retain control over your data; uninstalling the App removes it from your device.
11. Your Rights and Choices
You can:
- Stop using the App at any time.
- Uninstall the App to delete all local data.
- Manage permissions in your device settings (e.g., revoke storage or internet access).
- Choose not to download models and use only bundled models if available.
- Choose not to open external links.
If local data handling is subject to laws like the GDPR, we process data on the basis of necessity for the service and your consent where applicable.
12. Changes to This Privacy Policy
We may update this policy occasionally. We will note the “Last updated” date at the top. Continued use of the App after changes means you accept the updated policy. Major changes may be communicated in the App or through the Play Store listing.
