Question 1

Is Quilon more secure than cloud-based clipboard managers?

Accepted Answer

Yes. Quilon uses a strict zero-knowledge architecture. All data is encrypted client-side with AES-256-CBC before leaving your device. Unlike cloud managers, Quilon servers act only as blind relays and never see or store your plaintext data.

Question 2

How does the 'Auto-Redact' PII feature work?

Accepted Answer

Quilon includes a local OCR engine that runs directly on your device. It automatically scans screenshots for sensitive information like API keys, credit card numbers, email addresses, and IP addresses, allowing you to blur them instantly before sharing. No image data is sent to the cloud for processing.

Question 3

Which platforms does Quilon support?

Accepted Answer

Quilon offers a native desktop experience for Windows and macOS, and a powerful Progressive Web App (PWA) for iOS, Android, and Linux. This ensures seamless clipboard syncing across virtually any device combination without needing app store approvals.

Question 4

What are 'Brand Kits' in Quilon?

Accepted Answer

Brand Kits allow you to turn raw screenshots into professional assets instantly. You can apply custom backgrounds, padding, watermarks, and device mockups that match your company's branding guidelines—perfect for documentation and social sharing.

Question 5

Does Quilon store my clipboard history?

Accepted Answer

No. Quilon treats clipboard data as ephemeral. Content is synced in real-time via secure WebSockets and is not persistently stored on our servers. Once the session ends or the data is transferred, it's gone from the relay.

Question 6

Can I receive files from people who don't have Quilon?

Accepted Answer

Yes, using the 'Secure Drop' feature. You can generate a private, end-to-end encrypted link that allows others to securely upload files directly to your device, even if they don't have a Quilon account.

Question 7

Is there a free version of Quilon?

Accepted Answer

Yes. Quilon offers a Free tier that includes unlimited local syncing and basic redaction tools. For advanced features like Brand Kits, larger file transfers, and Secure Drop links, we offer Pro ($59/year) and Founder Lifetime licenses.

Question 8

How does Quilon compare to AirDrop or Pushbullet?

Accepted Answer

Quilon is the privacy-first alternative. While AirDrop is limited to Apple devices and Pushbullet has access to your notifications, Quilon works across Windows, Android, iOS, and Linux with military-grade encryption by default.
