Frequently asked questions
Is the free tier really free forever?
Yes. No time limit, no book limit. Library management, the built-in reader, format conversion, and all core features are free for life.
Can I import my existing Calibre library?
Yes — drag your ebook files, or your entire Calibre library folder, into Liber. Books are imported 100% locally; metadata and covers are detected automatically, and duplicates are skipped. Your original Calibre library is never modified.
Exactly which ebook formats does Liber support?
The built-in reader opens EPUB, PDF, and comics/manga (CBZ, CBR) directly. You can also import MOBI and AZW3 into your library — ideal for sending straight to a Kindle — plus FictionBook (FB2), Word (DOCX), RTF, plain text, Markdown, HTML, and OpenDocument (ODT) as conversion sources. Format conversion outputs to EPUB, AZW3, MOBI, CBZ/CBR or PDF.
What payment methods are accepted?
All major credit and debit cards, PayPal, Apple Pay, and Google Pay via Paddle, our payment processor and Merchant of Record.
Is tax included in the price?
Yes. The prices shown are the final amounts you pay, including all applicable taxes.
Can I cancel anytime?
Yes. Cancel from within the app via Settings → Premium, or via the link in your receipt email at any time. You keep Premium access until the end of your billing period.
What is the refund policy?
We offer a fully functional 7-day free trial, allowing you to evaluate Premium before purchasing. Because you can try all features before being charged, purchases are generally non-refundable, except where required by applicable law (e.g., for EU consumers). For details, see our Refund Policy or email support@tryliber.com.
How many devices can I use?
Each license can be used on one active device at a time. You can deactivate a device and transfer your license to another device at any time from Settings.
