Privacy Policy

// What This App Does

• Runs an AI model entirely on your device — your conversations never leave your phone.
• Downloads the AI model weights, survival reference PDFs, and offline map files to your device's local storage so the app works without internet in an emergency.
• All downloaded content is stored on-device only and is deleted when you uninstall the app.

// What We Do Not Do

• We do not create user accounts or require sign-up.
• We do not collect names, emails, phone numbers, or any personal information.
• We do not use analytics, crash reporting, or telemetry of any kind.
• We do not serve advertisements or share data with third parties.
• We do not track your location.
• We do not access your contacts, call logs, or messages.
• We do not upload your AI conversations, prompts, or anything you type into the app.

// Network Activity

The app connects to the internet for a small, fixed set of purposes:

• AI model download — on first launch the app downloads its AI model weights (~1.5 GB) so every subsequent chat runs fully offline on your device. The primary source is Hugging Face. If Hugging Face is unreachable, the app falls back to a mirror we host on Cloudflare R2.
• Reference PDFs — when you tap Download on a library item, the app fetches that file over HTTPS from our content server, which is hosted on Cloudflare Workers and backed by Cloudflare R2.
• Offline map files — when you tap Download on a map, the app fetches that map file from Cloudflare R2.

Requests carry only the file path and standard HTTP headers (IP address and User‑Agent). As network providers, Hugging Face and Cloudflare may log this metadata in their own systems for abuse prevention. We do not receive, retain, or correlate it with any user, and we do not transmit your AI conversations, prompts, or any personal data during these downloads.

// Downloads and Notifications

Because map files and the AI model can be large, downloads run in a background service that Android requires to show a persistent progress notification. The notification disappears when the download finishes or you cancel it. No information about the download is sent anywhere outside the request to fetch the file itself.

// Data Storage

All app data is stored in the app's private sandbox on your device (Android/data/app.prepperai.android/files/). This folder is created and managed by Android for this app only, is not visible to other apps, and is automatically deleted when you uninstall the app. We operate no cloud storage, no remote database, and have no way to access your data.

// Your Rights

Because we do not collect or store any personal information about you, there is nothing for us to access, correct, export, or delete on your behalf. You have full control on-device: delete downloaded files from within the app, or uninstall Prepper AI to remove everything at once.

// Children's Privacy

This app is intended for users 18 and older and is not directed to children. We do not knowingly collect personal information from any user, including children under 13.

// Changes to This Policy

If this policy changes, the updated version will be posted at this URL with a new date. Material changes will also be noted in the app's release notes.
