## Description

Your calendar is one of the most personal things you own — it knows where you'll be, who you'll meet, and what you're doing every hour of every day. Why hand that to a corporation? Calendar by Form* is a fully private calendar app built on the Nostr protocol. You sign in with your Nostr keys, and your events are stored privately(encrypted) across relays that you choose. You own your keys and stay completely in control of your data.
