About the USB key drive

Pro uses your own standard USB flash drive to hold the encryption key. Necron securely prepares the drive during setup. No special hardware is required.

Bring your own drive

Any standard USB-A or USB-C flash drive works.

Necron sets it up

The app securely formats and initializes it during setup.

Keep a backup

A second key drive protects you if the first one is lost or damaged.

FAQ

Frequently asked questions

Can I upgrade from Free to Pro later?

Yes! You can upgrade to Pro anytime from your account settings in the app. Your existing vault and files will be preserved.

Do I need to buy a USB key drive separately?

You provide your own USB key drive — any USB-A or USB-C flash drive with at least 1 GB capacity works. The Necron app will securely format and initialize the drive during key setup. No special hardware required — just a standard USB drive you probably already have.

What happens to my data if I cancel Pro?

Your encrypted data remains accessible. Your account will revert to Free tier limits (1 vault, 1 GB). You'll need to reduce your usage to within Free limits, but we'll never delete your data without your explicit consent.

Is my payment information secure?

We use Paddle as our payment processor. Your credit card details are handled entirely by Paddle and never touch our servers. Paddle is PCI-DSS compliant.

Can I get a refund?

Yes, we offer a 30-day money-back guarantee. Contact support@necronsolutions.com for refund requests.
