# `_nomap`

_{{ page.excerpt }}_

`_nomap` in the end of your SSID will exclude your network from Google, Apple, WiGLE etc.

Microsoft has a separate [location services
opt-out](https://account.microsoft.com/privacy/location-services-opt-out)
which uses MAC addresses instead.

## Why?

Privacy. WiGLE.net may point your home directly just by entering the SSID and who knows how many similar services there are. While I have been thinking of this since 2015, there is at least one case where this has been used:

## `_optout`

Legacy from 2015-2016. Used to be part of Microsoft WiFi Sense that shared WiFi networks and passwords to all contacts.
