Fifteen days of Pro, on the house.
Everything Pro mode adds — PDF with any engine, the single-file HTML and the navigable HTML book, the twelve Pro themes, statistics and numbering — unlocked for 15 days, so you can build a book and check the printed result before deciding.
Ask for your key
It arrives by e-mail, usually within a minute. It is issued to this address and the address is part of the key, so keep the two together — the application asks for both when you activate it. The mail is also why we ask: receiving it is what shows the address is yours.
If it has not arrived after a minute, look in your spam folder: a sender you have not seen before often lands there. Marking it as “not spam” also helps the next person.
What you get, and what happens after
- Everything Pro unlocks, for 15 days from the moment the key is issued. Nothing else changes: the free Basic mode is the same as always.
- When it ends, the app goes back to Basic mode. The books you generated are yours and stay where they are; what stops is generating new PDF or HTML files, along with the Pro themes, statistics and numbering.
- One trial per address. That is the honest reason we ask for it: a trial that could be restarted with a click would not be a trial.
- To activate it: download the app, open it, and choose Help → Activate Pro…. Paste the key and the address it was issued to.
We use the address to send you this key and to recognise that this address has already had a trial. We keep a scrambled record of it for a year for that, and delete the plain address as soon as the key has gone out. It is never matched against anything you buy, and the application itself still sends nothing anywhere. Privacy policy.
