You do. Your location is yours, and only your own sharing choices decide who sees it.
• It starts off. Nothing about your location is shared until you turn sharing on. • You choose each person or circle. Being in the same household, or paying for the plan, does not let anyone see your location. The organizer can invite people and suggest family settings, but cannot widen what you share. • You choose the places and times. Share only at school or work, everywhere except places you exclude, during set hours, or just for one outing, pickup or trip that ends on its own. • You choose how precise. Exact position, only the general area, or only the name of a place such as "home". One person can see more than another — for example your sister sees your exact location while the rest of the family sees the general area. • You can preview it. Crello can show you what a particular person would see right now under your settings. • You can pause or stop at any time. A pause stops new sharing and related alerts at once, and comes back only the way you chose, at the time you chose. Removing a person stops their view straight away.
A setting that says no always wins over one that says yes: an excluded place, a pause, a removed person or an ended rule beats every allow. Someone who may not see your location sees only "not shared right now", never why.
Assistants and other Memriq apps follow the same rules. Nothing they suggest or remember can widen who sees your location.
