The Basic plan is free and includes five flipbooks, unlimited pages, 1GB of storage, API access and password protection. Paid plans are listed from $5/mo (annual). Standard costs $5 a year, billed yearly, and includes unlimited flipbooks, 10Gb storage, three account users, white branding, offline downloads and basic support. Professional costs $14 a month and adds reader statistics, Google Analytics integration, lead forms and a custom URL. Premium costs $29 a month and includes 40Gb storage, a digital bookshelf, a custom URL and DNS domain, advanced password protection and priority support. Flipbooks are private by default and can be restricted by password or embedding domain. The API can manage flipbooks and password access, provide embed codes and receive leads through webhooks. A flipbook created without logging in is deleted after one week unless its creator logs in or registers.
