Rakuten Kobo Kobo Clara Colour (N367)

D2 Cloud-Optional — Full function with the router off.

The unplug test

Block Wi-Fi at the router and the Clara Colour keeps doing the one thing that matters: it opens and displays any EPUB, PDF or other supported file dragged onto it over USB, no Kobo account involved. Out of the box the setup wizard nudges you toward Wi-Fi and a Kobo Store account, but Kobo's own firmware includes a documented Sideloaded Mode that skips account creation entirely and disables only the cloud-dependent extras: the Kobo Store, Kobo Plus, OverDrive/Libby sync and Dropbox import. Firmware updates still appear to reach the device over Wi-Fi in this mode, so a permanently offline unit will fall behind on update checks it cannot make.

Why this tier: Kobo operates a real cloud (Kobo Store, Kobo Plus, OverDrive/Libby sync, Dropbox import), but the device's own firmware ships a documented Sideloaded Mode that completes setup and signs the device out with no Kobo account, and non-DRM ePub/PDF files transfer over USB with no login step described anywhere in Kobo's own instructions — so core reading function is fully achievable without ever touching Kobo's cloud.

Self-hostable full — fully replaceable on your own hardware
Kobo's own USB sideload path already replaces the store for personal libraries; pairing it with Calibre on a computer (library management, format conversion, metadata) reproduces the sync/organize function of the Kobo cloud entirely on hardware the owner controls.

Class A is primary (manual, FCC filing, teardown). Class B is corroborated community reporting. Class C is never sufficient alone.
