Comixology is sending emails to customers about an upcoming transition to Amazon for a new shopping experience, and the Comixology app is going to be updated soon as well.
Basically, the Comixology website will start redirecting people to Amazon’s website to shop for Comixology comics, and you can use either the Comixology app or the Kindle app to read your purchased content—apparently they both provide the exact same reading experience, but you can use the former if you just want to see all your comics, manga and graphic novels in one place.
You’ll be able to sync your Comixology and Kindle library, and you’ll have the ability to sync bookmarks and reading position between apps as well.
One of the negative side effects of this transition is DRM-free downloads will be going away. Here’s a quote from the FAQ:
Note: any books purchased in the new comiXology updated app or through Amazon will not come with DRM-free downloads.
They say DRM-free downloads will still be available in PDF and CBZ format for eligible purchases made on the old website or app, but unfortunately it looks like the new setup won’t allow for DRM-free downloads moving forward.
There’s also some interesting information about comics and Kindle ereaders in the FAQ:
Your comiXology comics, graphic novels and manga won’t appear by default on your (Kindle) E-reader devices. If you want to read one on those devices, you can head to your Content and Devices page, select the book, and choose to Deliver the book to your registered Devices. Due to memory limitations, we recommend you only send less than 25 books to your e-Reader device at a time. We also recommend you remove the book from your device when you have finished the book.
See the Comixology Amazon FAQ for more information about the upcoming transition.
