ToS Question About Pursuit.gg

I’m confused cuz I just got this email from blizzard:
Greetings,

We have identified that your account was logged into Overwatch while using unauthorized third-party applications, such as Visor or Pursuit. These programs provide benefits not normally achievable in the game, and detract from the integrity of the game environment.

The account holder is responsible for all activity on the account. This is only a warning and we are not penalizing your Blizzard or Overwatch account at this time. Continued use of unauthorized third-party programs will result in action taken against your account, up to and including a permanent ban, in accordance with the End User License Agreement (Blizzard End User License Agreement - Legal – Blizzard Entertainment).

If anyone knows anything about it, I’d like to know if I can use Pursuit or not.
