Readium LCP DRM included

A first-class listening experience with variable speed, sleep timer, chapter navigation, and background playback. Download-first architecture guarantees uninterrupted listening anywhere.

Technology that gets out of the way and lets readers read
The eBook reader and audiobook player are the core of the platform. Both are designed to be invisible — professional-grade features without the friction. eBooks and audiobooks appear together in a single My Library — cover art, progress, and download status visible at a glance.

Offline-first architecture across iOS, Android, and web
Content downloads to device. Notes sync when connectivity returns. Configurable device limits (typically three) reduce account sharing.
Protection that readers never see. Security that content always has.
Publish360 uses Readium LCP — the industry standard for EPUB DRM, developed by EDRLab to replace the friction and failure modes of Adobe Digital Editions. If your readers have ever struggled with DRM before, this is the technology built specifically to solve that.
Audiobook files are encrypted at rest with signed URLs that expire after use. Supplementary materials use social DRM — a watermark containing the purchaser's identity — a proportionate deterrent for clinical and professional content that must remain editable.
Invisible to legitimate readers
Readers open their purchase on their phone, tablet, or the web — without knowing any protection is in place. Files are locked to their account and device, making extracted copies non-functional outside the app.
Works fully offline
Downloaded eBooks are protected and readable without connectivity. No separate account or device authorisation step required — a reader clicks their title and it opens.
No device registration
Unlike Adobe Digital Editions, Readium LCP requires no frustrating device authorisation steps that created support overhead and damaged customer relationships.
Open, interoperable standard
Developed and audited by EDRLab — the non-profit digital publishing consortium. Eden Interactive is an EDRLab member. LCP is not locked to any single vendor.
