Limits worth knowing in Flask

  • Sharing has no permission settings: a list is shared by its URL, with no invites.
  • It is browser only. The About page asks developers who want to help build a mobile app to get in touch, and no native apps are offered.
  • The terms of use mention a paid PRO account, but the /pro page they point to returns a not-found page and the site lists no paid plan.
  • API access is given on request by email; the site has no public API documentation.
