- The web client's data is stored locally on the computer running the web browser. (This is done with the [Origin Private File System](https://developer.mozilla.org/en-US/docs/Web/API/File_System_API/Origin_private_file_system) API).
- Dropbox sync should work. Note, however, that I've only tested it with a small number of notes and resources. There might be synchronization bugs!

**I would advise against this for now** , mostly because the web client isn't very stable. In particular,

- ~~At present, having the web client open in multiple tabs at the same time could cause data corruption.~~
  - ~~Currently, it's possible for multiple tabs to try to sync at the same time.~~
  - **Edit** : This has been addressed. The web client now prevents multiple copies of itself from being open at the same time.

- The web client is auto-built from this work-in-progress [pull request](https://github.com/laurent22/joplin/pull/10650). New changes are being made to it frequently and these could potentially introduce sync and/or startup bugs.
- Web browsers [can clear locally-stored data for websites when the computer is low on memory](https://developer.mozilla.org/en-US/docs/Web/API/Storage_API/Storage_quotas_and_eviction_criteria#when_is_data_evicted). The web client [requests persistent storage](https://developer.mozilla.org/en-US/docs/Web/API/StorageManager/persist), which [**should prevent its data from being auto-cleared**](https://developer.mozilla.org/en-US/docs/Web/API/Storage_API/Storage_quotas_and_eviction_criteria#storage_pressure_eviction). However, I haven't tested whether the web client's data is preserved when a computer is low on memory.
