# 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.
