Privacy Policy
- AntapexAI runs its AI model entirely on your phone. Your messages, documents and voice never leave the device — unless you choose to report an AI reply to us.
- We run no servers, require no account, and use no analytics, ads or trackers.
- The internet is used only to download AI model files you choose, to check whether new models exist, and to send a report about an AI reply if you submit one.
- Everything is stored in the app's private storage, and you can delete it at any time.
1. Who we are
AntapexAI ("the app", "we", "us") is a private AI assistant published by codeAxee. After a one-time model download, the app runs an open-source language model locally on your Android device and works without an internet connection.
2. Data processed only on your device
The following information is created and kept only in the app's private storage on your phone. We never receive it, and no third party can access it through us.
| Data | Why | Where it stays |
|---|---|---|
| Chats (your messages and AI replies) | To show your conversations and give the AI context | On-device database |
| Attached documents (PDF, Word, text) | So the AI can answer questions about them; text is extracted on the device | Saved with the chat it belongs to |
| Local profile (name, optional email) | To greet you and keep each profile's chats separate. Never verified or sent anywhere | On-device database |
| Settings, personas and saved prompts | To remember your preferences | On-device storage |
| App-lock PIN | To protect the app. Stored only as a salted PBKDF2 hash — the PIN itself is never stored | On-device database |
| Voice input | Converted to text by your phone's speech service, preferring offline recognition. Audio is not recorded or stored by AntapexAI | Not stored |
| Crash details (only if the app crashes) | Written to a local file. On next launch you may choose to email it to us — nothing is sent automatically | On-device until you send or dismiss it |
Incognito chats are kept in memory only and are never written to storage.
3. When the app uses the internet
Model downloads
When you choose a model, the app downloads the model file directly from a public host: github.com/codeAxee/antapex-models (GitHub Releases) or huggingface.co. These are ordinary file downloads that contain none of your data. The host receives standard connection information (such as your IP address) as with any download, under its own privacy policy. You can restrict downloads to Wi‑Fi in Settings.
Model update check
The Models screen reads a small public file (codeaxee.github.io/antapex/models.json) to learn whether new models are available. No identifiers or personal data are sent.
Models you import yourself
If you paste a link to a model, the app contacts that address to download it. If you import a file from your phone, no network is used.
Reporting an AI reply
Every AI reply has a Report button. If you submit a report, the app sends us the reason you picked, any note you type, the app and Android version and the model used. By default it also includes the reported reply and the question that led to it; you can switch that off before sending. Nothing else from your chats is sent, and no name, email, profile or device identifier is included. Reports are sent over an encrypted (HTTPS) connection, queued on your phone until you are online, and removed from your phone once delivered. We use reports only to find and reduce harmful or inaccurate AI output, keep them for up to 12 months, and never sell or share them. To ask us to delete a report, contact us (section 10) with the approximate date and reason.
Chatting, documents, voice and all other features work fully offline.
4. Permissions
| Permission | Used for |
|---|---|
| Internet & network state | Downloading model files, checking whether you are on Wi‑Fi, and sending reports you submit |
| Notifications (optional) | Download progress, "reply ready" and "model ready" alerts |
| Microphone (optional) | Voice input and voice mode, only while you use them |
| Biometrics (optional) | Unlocking the app with your fingerprint or face, handled by Android — we never see biometric data |
| Foreground service | Finishing a model download or an AI reply when you leave the app |
| Vibration | Optional haptic feedback |
5. Security
Data lives in Android's app-private storage, which other apps cannot read. Android's cloud backup is disabled for app data, so your chats are not copied to any cloud by AntapexAI. Optional app lock uses a salted, hashed PIN with lockout after repeated wrong attempts, re-locking when you leave the app, and an option to hide content from the recent-apps screen. Backups you create yourself can be protected with a password (AES-256-GCM encryption).
6. Your choices and data deletion
- Delete any chat, or all chats, from the app at any time. Turn on auto-delete for older chats in Settings → Privacy & data.
- Delete a profile with all its chats, prompts and settings from the Profile screen.
- Export your chats (Markdown or JSON) or a full backup whenever you like.
- Uninstalling the app removes all of its data from your device.
Apart from reports you choose to send, we never receive your data, so there is nothing on our side to access, correct, export or delete — you are in full control on your device. For reports, see section 3.
7. Children
AntapexAI is not directed at children under 13 and does not knowingly collect any personal information from anyone. AI-generated text can be inaccurate or inappropriate; parents should supervise younger users.
8. Google Play data safety
AntapexAI collects data only when you submit a report about an AI reply. In Google Play's Data safety section this is declared as App activity → Other user-generated content (the reported reply, your question and your note): optional, collected only on your action, used for app safety and improvement, encrypted in transit, not shared with third parties, and deletable on request. No other data leaves your device; model downloads contain no user data.
9. Changes to this policy
If we change this policy, we will update this page and the effective date above. Material changes will also be noted in the app's release notes.
