## Analysis Parameters
Branches will be deleted automatically when they are inactive according to your settings at [Administration > Configuration > General Settings > Housekeeping > Number of days before deleting inactive branches](/#sonarqube-admin#/admin/settings?category=housekeeping) except for branches you have set to be kept when inactive. These branches are kept until you delete them manually at the project level at **Administration > Branches & Pull Requests**. See the [Branches Analysis](/branches/overview/) for more information on keeping inactive branches.
## Does my project need to be stored in an SCM like Git or SVN?
-No, you don't need to be connected to a SCM. But if you use Git or SVN we can better track the new files on short-lived branches and so better report new issues on the files that really changed during the life of the short-lived branch.
+No, you don't need to be connected to a SCM. However, SCM data still enhances the SonarQube exprerience (including issue auto-assignment and issue backdating), and you will be well prepared to take advantage of [Pull Request Analysis](/analysis/pull-request/)!
## What if I mark an Issue "Won't Fix" or "False-Positive" in a branch?
It will be replicated as such when creating a Pull Request and merging the Pull Request into the master branch.
Yes, an extra node called "branch" is added to the payload.
## When are Webhooks called?
-When the computation of the background task is done for a given branch but also when an issue is updated on a short-lived branch.
+When the computation of the background task is done for a given branch.
## What is the impact on my LOCs consumption vs my license?
The LOC of your largest branch are counted toward your license limit. All other branches are ignored.
