How Does Joplin Sync Notes Across Devices?

Updated

Joplin syncs notes by connecting every device you install it on to the same sync target — Joplin Cloud, Dropbox, or OneDrive — so the app uploads your notes from one device and pulls them down on the others. You need the app installed on each device and the same sync service configured on all of them; notes are protected with end-to-end encryption (E2EE), so the sync provider stores encrypted data rather than readable note content.

What you need before syncing

  • The Joplin app on each device you want to use. It runs on Windows, macOS, Linux, Android, and iOS, and a terminal app is also available.
  • One sync target chosen for all devices. Joplin's site lists Joplin Cloud, Dropbox, and OneDrive as supported services. The same target must be set on every device, or they will not see each other's notes.
  • Your encryption credentials. Because notes use E2EE, a new device needs the encryption key/password to decrypt what it downloads.

How the sync works

  1. You write or capture a note on one device — text, images, videos, PDFs, audio, math expressions, or diagrams.
  2. Joplin uploads that note to your chosen sync target.
  3. Other devices connected to the same target download the change and decrypt it locally.
  4. The note is then available on your computer, phone, tablet, or terminal.

The sync target is a transport and storage layer, not a place where your notes are readable — E2EE is what keeps the content private in transit and at rest.

Choosing a sync service

Option What it gives you When it fits
Joplin Cloud Sync plus sharing notes with friends, family, or colleagues for collaboration, and publishing a note to the internet via a URL. Based in France, under EU privacy law. You want collaboration or note publishing on top of sync, or prefer EU-based hosting.
Dropbox Sync only, using your existing Dropbox account. You already use Dropbox and only need to move notes between your own devices.
OneDrive Sync only, using your existing OneDrive account. You already use OneDrive and only need to move notes between your own devices.

Joplin Cloud is the only option in the site's material that adds collaboration and public note sharing; Dropbox and OneDrive are listed purely as sync services. Pricing for Joplin Cloud is not stated in the available material, so check the Joplin Cloud page before assuming a cost or a free tier.

What sync does not do by itself

  • It does not merge accounts. All devices must point at the same target.
  • It does not remove the need for your key. Without the encryption credentials, a freshly synced device cannot read the notes.
  • It does not make notes readable to the provider. E2EE means the service — including Joplin Cloud — cannot access your note content.

Verifying it works

After configuring the same sync target on two devices, create a test note on one and wait for sync to complete, then check whether it appears on the other. If it does not, the usual causes are a mismatched sync target, a failed login to the sync service, or a missing encryption key on the second device.
