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 will be accepted?
When Premium launches, we will accept all major credit and debit cards, PayPal, Apple Pay, and Google Pay via Paddle, our payment processor and Merchant of Record. Nothing can be charged today.
Is tax included in the price?
Yes. The prices shown are the final amounts you would pay, with all applicable taxes already included — no surprises at checkout.
Can I cancel anytime?
Yes. Once Premium launches you will be able to 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?
Premium is not on sale yet, so there is nothing to refund today — Liber is free to use. When Premium launches, purchases will be covered by our Refund Policy, including the statutory 14-day right of withdrawal for consumers in the EU, EEA and UK.
How many devices can I use?
Each license will work on one active device at a time. You will be able to deactivate a device and transfer your license to another one at any time from Settings. If you lose access to that device and cannot deactivate it yourself, email us at support@tryliber.com.
