Parents everywhere work hard to prevent their kids from reading inappropriate content, but sometimes it's not enough. A parent can choose their kid's books based on content summaries and maturity ratings, but sometimes bad language slips through.
And that's where an app like Clean Reader can help. This app applies a custom filter to the ebooks you're reading which removes the profanity and substitutes cleaner synonyms. It offers 3 different filter levels: clean, cleaner, and squeaky clean (in the last setting, the developers go wash the author's mouth with soap).
Clean Reader is the inspiration of a couple of parents who couldn't find this type of reading experience in the major ebook platforms. Sure, Kobo offers a Kids Store and Amazon offers Kindle Freetime Unlimited, but those options don't guarantee freedom from profanity. Obscenity, yes (probably), but not profanity.
The technical work on the app was developed by Page Foundry, a lesser-known but long-established ebook startup. The Clean Reader app offers its own ebookstore which does carry the broad selection of titles you'd expect. (I believe that store is built on Inktera, a Page Foundry site.)
I haven't bought any ebooks, but I can see that the Inktera store is Epub-based and does support Adobe DE DRM.
I can also report that Clear Reader for the iPad will let you sideload Epub ebooks. I tried with a DRM-free title, and then applied the filters. Some of the filter decisions struck me as silly, but it did work:
I don't know about anyone else, but this is the first time I can recall seeing this type of app. And that surprised me. I would have thought that this type of content filter would be relatively easy to implement and also be highly desired by certain customers.
Not everyone, for example, wants their kids to read the unexpurgated Huckleberry Finn with multiple uses of the n-word. I know that this is an unpopular viewpoint in certain circles, but some readers and some parents want to read the story without being distracted by the profanity.
And Clean Reader can help.
