Granting or restricting permissions on the Tools app

I am serving as Ward Clerk currently and our Bishop reached out to see if I am able to see what 'Permissions' people have when accessing the Tools app. Apparently a couple members in our ward are reporting that they have access to some sensitive information for our ward, and they are not serving in callings that would require them to be able to view this information.
They have not recently made any changes in their callings, that could explain this.

Any suggestions? Is there a place we can go to on the Ward level to see who is supposed to have access to what, and make changes if needed?

You can see the access table in LCR. Log in to LCR and select Help --> Feature Access by Calling.

Not requesting you to disclose what sensitive information they are reporting, but a common misconception when members think everyone can see their birth date because they can. If this is what they are reporting, it is normal behavior because anyone can see their own information even if other members cannot.

In addition to what davesudweeks said, note that members of the ward council have access to sensitive information, because they are responsible for the ward members. (See General Handbook 29.2.5.)

That means a primary president can likely see the birthdate of a single brother.

Regarding the O.P., I don't believe local leaders have any control over what individual members see when using the Tools app, that's all determined by their calling. If someone is repeatedly misusing member data, other Forum posts have indicated GSD can restrict access, but in general that's about it.

A number of Forum members have experienced "data ghosts", where the Tools app does not correctly sync the data when a calling changes (and for a number of other scenarios). So even if those members were released from a leadership calling a while ago, it's possible their Tools app still has some remnants of "sensitive data", and a "Data Refresh" on that member's Tools app would resolve that.

And if "sensitive information" is the contact info of somebody who has set their access to private, then perhaps either that hasn't synced to everyone's Tools app correctly, or perhaps they set it to "ward members" instead of "presidencies".
