Set up Next Up by URLflows with a personal Google account

Before you start

• Download Next Up for personal accounts (next_up_personal.html), save it somewhere it can stay, and double-click it to open it in Chrome — see Download and open Next Up. Using a work or school account? Follow the Google Workspace guide instead.
• Make sure Chrome is signed in to the Google account that has your calendar.
• Want to look around first? Click Try a demo first to see Next Up with sample events. A banner stays at the top while the demo runs: click Set up my calendar when you're ready, or Exit demo. Connecting your own calendar ends the demo, and the Demo button at the bottom of Settings brings it back.

Click Start setup (or Settings) and work through the three numbered steps on the Setup tab. Settings save as you go. On a wide screen, Settings opens on the left with the page beside it, so you can see each change as you make it.

Step 1: Create your calendar bridge

A file on your computer can't sign in to Google by itself, so you add a small script to your own Google account that passes your events to Next Up.

1. Click Copy script.
2. Open a new Apps Script project signed in with the Google account that has your calendar, and rename it Next Up by URLflows bridge (click "Untitled project" at the top).
3. Select all the starter code, paste the script over it, and press Ctrl+S (Cmd+S on a Mac) to save.
4. Click Deploy → New deployment, click the gear icon next to "Select type" and choose Web app.
5. Set Execute as: Me and Who has access: Anyone.
6. Click Deploy, then Authorize access and pick your account.
7. Copy the Web app URL (it ends in /exec).

Why "Anyone" is safe

"Anyone" means anyone can reach the script, not read your calendar. The script only answers requests that carry your personal key, and it refuses anyone signed in to Google as someone else. "Only myself" also works in plain Chrome, but browsers that block third-party cookies, such as Brave and Safari, can't connect with it.

About the "unverified app" warning

When you authorize, Google says "Google hasn't verified this app". That's expected for a script you made yourself. Click Advanced → Go to Next Up by URLflows bridge (unsafe), then Allow. The script can only read your calendars, and you can read every line of it before you paste it.

Step 2: Connect

1. Paste the Web app URL into Your Web app URL.
2. Click Get my key. Your script opens in a new tab and shows your personal key.
3. Copy the key and paste it into Your personal key. Treat it like a password.

Step 3: Pick your calendars

1. Click Load my calendars.
2. Tick the calendars to watch. The colour swatch changes a calendar's colour in Next Up only — not in Google Calendar.
3. Optionally choose a Focus day agenda calendar to show today's timeline beside the timer.
4. Click Done.

The status pill in the header turns to Connected and your next event appears.
