Sync across devices

Paste your Supabase project details below. Do this once per device — use the exact same sync code on every device to share the data.

First time? Do this once

1. Go to supabase.com, sign in with Google, create a new project (any name, any region, set a password).
2. Wait for it to spin up (about 2 mins), then open the SQL Editor (left sidebar) and paste this then hit Run:

   create table holiday_data (
     sync_key text primary key,
     data jsonb,
     updated_at timestamptz default now()
   );
   alter table holiday_data enable row level security;
   create policy "public access" on holiday_data
     for all using (true) with check (true);
   alter publication supabase_realtime add table holiday_data;

3. Go to Project Settings (gear icon) → API. Copy the Project URL and the anon public key into the fields above.
4. Make up a sync code and use the same one on every device.
