This is cool news for journalers who like a blend of digital and analog. I don’t use Day One much anymore because I prefer a paper notebook, but if I did use it, I’d take advantage of this new best-of-both-worlds offering on at least an annual basis.
Of particular note is this bit on privacy:
All digital files are securely transferred to our printing facility. Printing is automated without any manual handling of the files. After printing is completed, your book is promptly packed, sealed, and shipped to your home. Any digital files used in the printing of your book are automatically deleted once this process is completed.
