Why Privacy Matters in Your Personal Knowledge Base

The Business Model of "Free"

The internet is littered with free tools. But as the adage goes: "If you're not paying for the product, you are the product."

Many "free" productivity tools monetize by:

1. Mining your text for advertising keywords.
2. Training AI models on your personal data.
3. Selling aggregated user behavior to third parties.

StartAppNotes takes a different path. We are a paid product (with a generous free trial). This simple exchange of money for service aligns our incentives: We work for you, not for advertisers.

Our Security Architecture

We’ve built StartAppNotes from the ground up to minimize data exposure.

1. Zero-Knowledge Encryption (Optional)

For our most security-conscious users, we offer end-to-end encryption features where we technically cannot read your notes even if compelled to. Your password generates the encryption key on your device, and that key never leaves your possession.

2. Encryption at Rest & Transit

All data on our servers uses industry-standard AES-256 encryption. All data in transit uses TLS 1.3. This protects against external breaches and "man-in-the-middle" attacks.

3. Biometric App Lock

Sometimes the threat isn't a hacker in a hoodie; it's a curious friend looking at your unlocked phone. StartAppNotes supports FaceID / TouchID locking at the app level. You can hand your phone to someone to show a photo without fearing they'll stumble into your personal journal.

Data Ownership & Portability

True privacy means the freedom to leave.

Many apps lock your data into proprietary formats (.note or complex databases) that make switching impossible. We believe your data is yours.

• Markdown Native: Our core storage format is compatible with Markdown.
• One-Click Export: You can export your entire library to a ZIP of plain text/Markdown files at any time.
• No Vendor Lock-in: Move your notes to Obsidian, Notion, or a physical notebook whenever you want. We want you to stay because you love the app, not because you're trapped.

The Future of Private AI

We are exploring AI features (like auto-summarization) but strictly on an opt-in and privacy-preserving basis. We pledge never to train public models on your private notes without explicit consent.

Conclusion

Your personal knowledge base is an extension of your mind. It deserves the same protection as your thoughts. With StartAppNotes, you have a safe, secure, and private place to think.
