What Notesnook provides

Notesnook organizes notebooks, tags and attachments across desktop, mobile and web clients with end-to-end encryption and optional synchronization. Encryption protects note content during the supported flow, but account recovery material, device keys, local unlock settings and exports still need their own retention plan.

Add devices one at a time

Start with a small sample containing text, lists, code, images and attachments. Confirm a complete sync on the primary device, export important notes and then add another device. Offline edits should be checked after reconnecting for conflicts rather than treated as an independent backup.

GUIDE

Notesnook encryption and sync guide

Create a small test notebook, configure encryption and recovery materials, sync it to one additional device and verify an export before moving long-term notes.

Before you start

  • Choose the desktop, mobile or web client and prepare a test notebook and independent backup directory.
  • Record recovery materials and device inventory without storing them beside the notes.
  • Prepare samples with Chinese text, lists, code, images and attachments to check completeness.
01

Installation steps

  1. 01

    Install and sign in

    Install the platform client, check language, notifications and local-storage permissions and create a test notebook before importing formal data.

  2. 02

    Configure encryption and recovery

    Follow the encryption setup, preserve required recovery material in an independent location and avoid placing recovery information in the same folder as the notes.

  3. 03

    Complete the first sync

    Write a small sample on the primary device, wait for synchronization and add one other device only after checking titles, tags, attachments and modified times.

02

Quick start

  1. 01

    Test offline editing

    Make a small offline change, reconnect and observe sync completion or conflict prompts; preserve an export before resolving an unexpected result.

  2. 02

    Export important notes

    Export a representative notebook, open the export from an independent location and record the version and date before treating it as a recovery copy.

  3. 03

    Migrate a new device

    Confirm the old device is synchronized, add the new device, verify sample attachments and only then remove data from the old device.

Usage tips

  • End-to-end encryption does not remove the need to protect recovery materials, device keys and local unlock settings.
  • Sync copies are not the same as an independent export or backup.
  • Add attachments and devices gradually so a conflict has a small, recoverable scope.
Troubleshooting and uninstall

Why are notes or attachments missing on a new device?

Check account, encryption recovery, sync state, storage permission and attachment upload status and compare with an export before importing more data.

What should I do after an offline conflict?

Preserve both versions, stop further edits, verify device clocks and sync state and resolve from a copy rather than overwriting the only version.

  1. Export and verify notesExport important notebooks and attachments, open the export independently and record recovery material and connected-device state.
  2. Sign out and remove the clientWait for synchronization, sign out where applicable, remove the device from the account and uninstall through the platform after verifying the export.
FAQ

Frequently asked questions

What does end-to-end encryption protect in Notesnook?

It keeps supported note content encrypted through synchronization, but recovery material, device keys, local unlock settings and exports still require careful protection.

Does Notesnook support offline editing?

Synchronized content can be edited offline and checked after reconnecting, but conflicts and incomplete attachments still need review and important notes should be exported.

What should I do before replacing a phone?

Confirm the old device has finished syncing, export key notes, record recovery steps and verify the new device before clearing old data.

Does the download require an extraction code?

The Quark entry does not require one; the four-character code for the Baidu entry is shown beside its download entry.
