One Google key works for both jobs — two keys are optional, useful only for separate billing or rate limits.

Used for reading photos and writing titles, descriptions, and tags.

Optional. Only needed if you later enable AI image editing/generation. Can be the same key as above.

Stored only in this browser (fky_settings). Sent directly to generativelanguage.googleapis.com when you use AI labeling — nowhere else.

Add or remove who can log in. Everyone shares the same library. Enter your admin key to manage.
