Privacy & Data Protection
Your privacy is our top priority. PJais is built with a privacy-first philosophy - your data stays on your device by default, and you have complete control over what gets shared.
Privacy at a Glance
- Store all data locally on your device
- Encrypt sensitive data at rest
- Process AI requests locally when possible
- Give you full control over your data
- Provide optional, encrypted cloud sync
- Allow you to export all your data anytime
- Send your data to our servers by default
- Track your conversations or behavior
- Sell or share your personal information
- Use your data to train AI models
- Require an account to use the app
- Include third-party trackers or analytics
Our Privacy Principles
All your personas, conversations, and settings are stored locally on your device. PJais works completely offline - no internet connection required for core functionality.
What this means for you:
- • Your conversations never leave your device unless you choose cloud sync
- • No one can access your data without physical access to your computer
- • You maintain complete ownership and control
- • Works offline - no dependency on external servers
If you enable cloud sync, your data is encrypted on your device before it's sent to our servers. We never have access to your encryption keys, so we can't decrypt your data.
Technical details:
- • End-to-end encryption using AES-256
- • Encryption keys derived from your password
- • Keys never leave your device
- • Even our servers can't decrypt your data
PJais is open source. You can review our code, verify our privacy claims, and even build your own version if you want complete control.
Open source benefits:
- • Security researchers can audit our code
- • Community can verify privacy claims
- • No hidden tracking or data collection
- • Transparent about what data we collect (spoiler: very little)
Every feature that involves data sharing is opt-in. Cloud sync, analytics, crash reports - all disabled by default. You choose what to enable.
You control:
- • Whether to enable cloud sync
- • Which AI providers to use
- • What data to export or delete
- • Anonymous usage statistics (opt-in only)
Where Your Data is Stored
By default, all your data is stored in an encrypted database on your local device:
Windows
%APPDATA%/pjais/macOS
~/Library/Application Support/pjais/Linux
~/.config/pjais/With a Pro subscription, you can enable encrypted cloud sync to access your personas and conversations across all your devices.
How it works:
- Your data is encrypted on your device
- Encrypted data is sent to our secure servers
- Other devices download the encrypted data
- Data is decrypted locally on each device
What gets synced:
- • Personas and their configurations
- • Conversation history
- • Memory and context data
- • App settings and preferences
AI Provider Privacy
When you use AI features, you can choose between local processing or cloud-based AI providers. Each option has different privacy implications.
Run AI models directly on your device. Your conversations never leave your computer.
Use cloud-based AI services (OpenAI, Anthropic, etc.) for more powerful models.
Common Privacy Questions
No. Your conversations are stored locally on your device and encrypted. Even if you enable cloud sync, we use end-to-end encryption, so we can't read your data.
Absolutely not. We never use your conversations, personas, or any personal data to train AI models. Your data is yours alone.
By default, we collect minimal data:
- App version and operating system (for compatibility)
- Crash reports (only if you opt-in)
- Anonymous usage statistics (only if you opt-in)
We never collect your conversations, personas, or personal information.
Yes! You can delete all your local data from Settings → Privacy → Delete All Data. If you use cloud sync, you can also delete all synced data from your account dashboard.
Yes. PJais is designed with GDPR principles in mind: data minimization, user control, transparency, and the right to deletion. Since data is local-first, you have complete control.
If you lose your password, we cannot recover your encrypted data - that's the nature of zero-knowledge encryption. Make sure to store your password securely. You can export unencrypted backups as a safety measure.
