Some users of static-site generator applications like ChowDown have expressed concerns about their data being stuck in a database. Considering this is a new project it is a valid concern to be worried about your data. Mealie specifically addresses this concern by provided automatic daily backups that export your data in json, plain-text markdown files, and/or custom Jinja2 templates. This puts you in controls of how your data is represented when exported from Mealie, which means you can easily migrate to any other service provided Mealie doesn't work for you.
