What Do Local-First and Read-Only OAuth Mean?

Local-first means working data is stored on the user’s device; read-only OAuth grants access to retrieve data without permission to modify it.

Why it matters

Together they reduce unnecessary data transfer and limit the consequences of a compromised or mistaken action.

How to use it

Request the narrowest Google scope, explain every browser permission, store only necessary settings and cache, provide disconnect and deletion controls, and avoid server transfer unless required.

Limits and interpretation

Local storage is not automatically encrypted or backed up, and removing the browser profile can remove data. Read-only access still handles sensitive account data and needs clear disclosure.

Common mistakes

Requesting broad scopes; claiming “no data” while processing Google data; keeping tokens longer than necessary; hiding permission reasons.
