Amazon Kindle App Store Download Terms Restrict Developers

Engadget and Daring Fireball point out the Amazon’s recently announced app active content store is going to make it nearly impossible for developers to add any sort of internet connectivity without incurring hefty download fees. So let’s see, 16 shades of gray, limited motion and no connectivity. Fuuuun.

We were wondering how Kindle’s impending active content (read: apps) would be harnessing that free Whispernet bandwidth. As it turns out, there’s just a smidgen allowed for gratis. According to the terms laid out by Amazon, there’s a 70 / 30 revenue split, with that smaller percentage going to Bezos and co. “net of delivery fees of $0.15 / MB.” The price tiers is a little simpler: apps can be free if their download over 3G is less than 1MB and they use less than 100KB per month, per user.

Apps between 1MB and 10MB require a one-time purchase fee that offsets the bandwidth usage, and likewise a subscription fee is needed for those that plan on allowing over 100KB of a monthly data streaming. (To put that in perspective, this post — just the copy — is 4KB. That image above is 120KB.) Anything over 10MB requires a download over WiFi, and the maximum file size is 100MB… and if anyone manages to justify a 100MB app that runs on a greyscale E Ink display, color us impressed.

Active content will be available to customers in the Kindle Store later this year. Your active content can be priced three ways:

Free — Active content applications that are smaller than 1MB and use less than 100 KB/user/month of wireless data may be offered at no charge to customers. Amazon will pay the wireless costs associated with delivery and maintenance.

One-time Purchase — Customers will be charged once when purchasing active content. Content must have nominal (less than 100 KB/user/month) ongoing wireless usage.

Monthly Subscription — Customers will be charged once per month for active content.

So for free and one-time-charge apps, there’s a monthly limit of 100kilobytes of bandwidth. Go over that and the developer has to start paying the bill. As point of reference for just how small 100 KB is, the Daring Fireball RSS feed at this moment is 115 KB. With gzip compression, it shrinks to 36 KB. So even with compression, a free or one-time-charge Kindle app could only download the DF RSS feed twice per month without going over.
