Hi there, this is Andreas Antonopoulos, the founder of Safe Paper Wallet.

If you have any questions about the security of our product, please ask.

We do not, ever, see your keys as you should print them onto our wallets with your computer offline. You can also use our service for free, but then you don't get the nice paper and security stickers ;-)

All the software is open source and the source is visible in the page itself.

Thanks for considering Safe Paper Wallet.
