By downloading, installing, or using Jemmah, you agree to be bound by these Terms. If you do not agree, uninstall the app immediately. These Terms constitute a legally binding agreement between you and Tejas Patil / SKYLabs India Private Limited.
Jemmah is intended solely for users aged 18 years and above. By using this app, you confirm you meet this requirement.
Jemmah is an offline-first, privacy-focused personal assistant for Android. It runs entirely on your device. Features include:
Development Disclosure: Jemmah was built using AI tools including Gemini and Claude. The app does not connect to any AI cloud service during normal use.
Jemmah includes a fully local App Lock system:
All PIN values and lock preferences are stored locally on your device only. No server, no cloud, no recovery mechanism exists.
⚠️ CRITICAL WARNING — NO PIN RESETS & PERMANENT LOCKOUT
WE DO NOT SUPPORT PIN RESETS UNDER ANY CIRCUMSTANCES.
If you forget your PIN and your fingerprint stops working (due to OS upgrade, hardware failure, device reset, or biometric re-enrollment), you will be permanently and irreversibly locked out of the app and all data inside it.
Tejas Patil and SKYLabs India Private Limited hold absolutely no liability for loss of app access or loss of data resulting from a locked state. It is entirely your responsibility to remember your PIN and maintain valid biometric enrollment on your device. PROCEED WITH CAUTION.
Jemmah is provided "AS-IS" and "AS-AVAILABLE." We make no guarantees regarding reliability, accuracy, or fitness for any purpose. AI outputs may be inaccurate, incomplete, or inappropriate and are not a substitute for professional legal, medical, or financial advice. You use the app entirely at your own risk.
To the maximum extent permitted by Indian law, Tejas Patil and SKYLabs India Private Limited shall not be liable for any direct, indirect, incidental, or consequential damages arising from your use of Jemmah, including data loss, device malfunction, or financial loss.
All data is stored locally on your device. Uninstalling Jemmah permanently and irreversibly deletes all your notes, tasks, passwords, files, and history. There is no backup or recovery mechanism. We strongly recommend maintaining your own backups.
The password vault and accounts ledger store data in a local SQLite database protected by Android's standard app sandbox isolation. No additional encryption is applied beyond what Android provides natively. You are solely responsible for the data you store.
Jemmah supports third-party AI models in GGUF format. The app does not bundle any model. You must download and import models independently. By using any model, you agree to its license:
SKYLabs India Private Limited is not responsible for your compliance with third-party model licenses.
You must not use Jemmah to store credentials belonging to others without consent, generate content for harassment or illegal activity, or decompile/reverse-engineer the application.
The Jemmah name, logo, and user interface are the exclusive intellectual property of Tejas Patil. You are granted a limited, personal, non-transferable license to use the app on your Android device.
These Terms are governed by the laws of India. All disputes shall be subject to the exclusive jurisdiction of the courts of Bengaluru, Karnataka, India.
Jemmah collects absolutely no personal data. We have no backend servers, no cloud databases, no analytics, no crash reporting, and no advertising SDKs. You are never required to create an account or provide any personal information.
Because no personal data is ever collected or received by us, SKYLabs India Private Limited is not a "Data Fiduciary" under India's Digital Personal Data Protection (DPDP) Act, 2023.
All data you enter — notes, tasks, calendar events, passwords, account entries, chat history, media files — is stored exclusively in a private SQLite database and AsyncStorage on your device. This data is inaccessible to other apps and cannot be read externally unless your device has been rooted or compromised.
If you activate the App Lock feature, your chosen 4-digit PIN and biometric preference are processed entirely on-device and stored locally in isolated system registers. No network entity can access or query this security setup.
All AI inference happens entirely on your device's CPU/GPU. Your messages, prompts, and chat history are never sent to any external server — not to us, not to Google, Meta, Microsoft, or any other party.
Jemmah uses the internet only for downloading AI model files from HuggingFace (user-initiated) and opening links you have saved in your default browser (user-initiated). No background data transmission occurs.
You have complete control over your data. To delete all Jemmah data: use "Delete All Chats" in Settings, go to Android Settings → Apps → Jemmah → Storage → Clear Data, or uninstall the app. All actions permanently and irreversibly delete all your data.
Jemmah is not intended for users under 18. We do not knowingly collect data from minors.
