👋 1. Introduction

Welcome to Offline Tippani ("we," "our," or "us"). We are committed to protecting your privacy and ensuring the security of your personal information. This Privacy Policy explains how we handle your data when you use our mobile application.

📊 2. Data Collection

Offline Tippani is designed with privacy as a core principle. We do not collect, store, or transmit any personal data to external servers. All your notes, content, and data remain exclusively on your device.

The app does not have Android's permission to use the internet, so it has no way to send your data anywhere.

Here's what we DON'T do:

• No user accounts or registration required
• No cloud storage or backup to our servers
• No tracking cookies or analytics
• No third-party data sharing
• No advertising or marketing data collection

💾 3. Local Storage

All data is stored locally on your device using encrypted storage:

• Notes and content: Encrypted using SQLCipher (256-bit AES encryption)
• Images and files: Stored in your device's secure app directory
• Encryption keys: Securely managed using Android Keystore
• Backups: A backup is a file you create and share yourself, encrypted with a passphrase you choose. Where it goes is up to you; we never receive it
• No cloud sync: Data never leaves your device
• Device-only access: Your data is only accessible through the app on your device

🔑 4. Permissions

The app requests one permission:

• Camera: To photograph a page for text recognition. Used only when you choose to take a photo.

It does not request storage or internet access. Photos and documents you import are chosen through Android's own photo and document pickers, which give the app access to the one file you pick and nothing else.

This permission is used solely for its stated purpose and does not involve data collection or transmission.

🚫 5. Third-Party Services

Offline Tippani does not use any third-party services that collect data:

• No analytics services (Google Analytics, Firebase, etc.)
• No crash reporting services
• No advertising networks
• No social media integrations
• No location tracking services

Two Google components run inside the app, on your device only:

• Google ML Kit reads text from photos. Its model is part of the app and works offline. ML Kit can report usage statistics to Google; that reporting is switched off in this app, and the app has no internet access in any case.
• Android AICore writes summaries on phones that support it, using Google's Gemini Nano model on the device. AICore is part of Android, and Android downloads and updates the model, not this app. On other phones the app's own summarizer runs on the device instead.

We do not share your data with any third parties because we do not have access to your data in the first place.

🔐 6. Data Security

We take data security seriously:

• Encryption: All notes are encrypted using industry-standard SQLCipher encryption
• Key Management: Encryption keys are securely stored using Android Keystore system
• Encrypted backups: Backups are encrypted with AES-256-GCM, using a key derived from your passphrase with PBKDF2. We cannot recover a forgotten passphrase, and neither can anyone else
• No Transmission: No data is transmitted over the internet
• User Control: You have full control over your data at all times
• Open Source Algorithms: We use proven, open-source encryption standards

👶 7. Children's Privacy

Offline Tippani does not knowingly collect data from anyone, including children under 13. Since all data remains on the device, there is no collection, transmission, or storage of personal information on our servers.

🗑️ 8. Data Deletion

You can delete your data at any time:

• Individual notes: Can be deleted from within the app
• Recycle Bin: Deleted notes are kept for 30 days in Recycle Bin, then permanently deleted
• Complete removal: Uninstalling the app will remove all data from your device
• Backups: Backup files you exported are stored wherever you saved them; delete them there
• No residual data: No data remains on external servers (because we don't use any)

🔄 9. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be reflected in the app with an updated "Last updated" date. We encourage you to review this policy periodically.

Material changes will be communicated through:

• The updated date on this page and in the app
• Play Store update notes
