How it works

Three steps — and the file stops leaking

01

Upload a PDF

One file in your cabinet. Nothing to convert or configure — the document is ready for protected viewing right away.

guide-v4.pdf · 84 pages
02

Issue a licence

One licence, one reader. Email, term, device limit — and the reader gets a link.

maria@example.com 3 devices no expiry
03

The reader opens the Reader App

Passwordless sign-in by email, contents and search. A personalised mark on every page — the file stays with you.

Who it is for

Experts and writers whose value sits inside the file

Expert

A handbook, a PDF course, checklists, templates, a guide, a study. You sell straight to your own audience.

Without protection the material lands in a private chat ten minutes after the first sale.

lawyers psychologists and coaches nutrition and fitness relocation and legalisation financial advisers teachers and tutors stylists and image designers and architects marketers craft makers

Writer

A book, a collection, a serialised release, a longread. You sell it yourself — no publisher, no platform.

Distributors take a cut, and a pirated copy shows up before the print run does. You set the licence price.

non-fiction fiction poetry memoirs and biographies popular science self-publishing series and issues
How we protect it

We do not give out the file. We give out access

Pages are rendered on the server and delivered as an encrypted image. There is no PDF to download — on the reader's side it does not exist.

Server encrypted image Device

Server-side rendering

No PDF on the device — only an encrypted image of the page.

One device at a time

Up to three approved devices per licence, reading from one of them.

Personalised watermarks

The reader's email and name across the document, with adjustable density.

No browser cache

Pages are never stored, and unwanted actions are blocked.

Revoke and freeze

Access closes immediately — permanently or for a while.

Data in the EU

Hosting and processing inside the European Union, GDPR compliant.

Honestly: 100% protection does not exist

We shut down mass piracy, not a determined specialist: reassembling the document piece by piece is still possible, it is just slow and expensive. Even banks have leaks — nobody can promise a full guarantee.

Reading analytics

How many reach the end, where interest drops, which pages get re-read.

Licence management

Lifetime, device limit, protection settings, revoke and freeze — separately for every licence.

We handle the licences only — the sales stay entirely yours: sell where you already do, take payment your own way. We take no cut of your turnover and never see your payments.
