Yes! You can upgrade or downgrade your plan at any time. When upgrading, you'll get immediate access to new features. When downgrading, changes take effect at the end of your current billing period.
Yes. Export your finished book (DOCX, EPUB, PDF, text) on every plan, the Free plan included, so you can publish and sell it. Only your finished book or script exports, on every plan: outlines, the Story Bible, characters and maps stay on the site.
The monthly number is how many chapters are drafted for you each month, not how long your story can be. On Creator (15 a month) you can outline the whole book and have chapters drafted over a couple of months, or buy a chapter pack for more anytime.
All your existing worlds are preserved. You just won't be able to draft more chapters, portraits, covers or maps beyond your new plan's limits until the next billing cycle.
Yes. You can cancel your subscription at any time from your account settings. Your access continues until the end of your current billing period, and you won't be charged again.
Yes. You retain 100% ownership of all content you create with Novarrium. This includes characters, worlds, maps, chapters, and everything you build.
