Is Copeel made by Tesla?

No. Copeel is an independent app, made by the French company COPEEL, with no ties to Tesla, Inc.

It connects to your car through the official access Tesla opens to third-party apps: you sign in on Tesla’s own page, you choose what Copeel can do, and you can remove that access at any time from your Tesla account.
