Sync across your devices

Pick a tier

	Local only (default)	Quick sync	Full private sync
Setup	none	one switch	Drive connect + a passphrase, once per device
Carries	nothing	your theme, layout and widget choices, plus tasks, countdowns and projects	your notes, dates, habits, bookmarks and Belief Genome, plus tasks, countdowns and projects
Reaches	this device	Chrome ↔ Chrome or Edge ↔ Edge signed into the same browser account	any browser, any computer
Privacy	nothing leaves the device	uses your browser account's sync (like Chrome bookmarks), without end-to-end encryption	end-to-end encrypted in one file in your own Google Drive

Quick sync never carries your Belief Genome, notes, dates, bookmarks, memories or API keys. They're either too large or too sensitive for the browser's small sync store. API keys and a local AI server address never sync on either tier. They stay on the device you entered them on. Your Memories archive is covered by backups.

Turn on Quick sync

1. Settings → Data → Sync → Turn on Quick sync.
2. That's it. Do the same on your other Chrome (or Edge) signed into the same account. Your setup, tasks, countdowns and projects follow you within a minute or so. The status line shows how much of the browser's small sync store you're using.

Turn on Full private sync

1. Settings → Data → Sync → Full private sync. Choose a sync passphrase with 8 or more characters, made up by you. It's never uploaded. Keep it in a password manager.
2. Click Sync now. The first time, Google asks permission for BGP to manage only the files it creates in your Drive.
3. On each other device, enter the same passphrase and click Sync now. After that, sync runs by itself: when you open a tab, come back to it, change something, and every 15 minutes as a backstop. Click the sync dot in the top bar to sync on demand.

What to expect

• Sync merges changes. Two devices editing the same list end up with both edits. A deleted item stays deleted on every device.
• Widgets update live when sync brings in changes. You don't need to reload.
• Sample content doesn't sync. The starter items on a fresh install stay on that device unless you edit them. Once you edit one, it syncs like anything else. A new device joining your sync drops its own untouched samples and shows your real data.
• Lose the passphrase and the synced file can't be opened. There's no reset, by design. Your data on each device is untouched. You can start sync again with a new passphrase.

Troubleshooting

My two browsers don't sync with Quick sync.

• They must be signed into the same browser account (check the profile avatar). Two different Google accounts are two separate sync stores.

"Wrong passphrase."

• The passphrase must match exactly on every device. Nothing is changed when it's wrong.

Quick sync is greyed out.

• It isn't available in the Mac app or in browsers without built-in sync. Use Full private sync there.

Something looks stale after a change on the other device.

• Click the sync dot. Changes made in Settings sync too, but a tab that was already open may need a moment.
