Based on the available information about the Lyft "TRANSJOY" offer in Kansas, there is no evidence that using the code will "out" you to your driver or the public.
Here are the key details regarding privacy and the promotion:
How the Code Works: The promotion involves entering a promo code ("TRANSJOY") in the app to receive 50% off rides in Kansas for a limited time (up to 3/9/26). It is designed to assist trans and non-binary individuals whose licenses were invalidated by a new state law.
Driver Knowledge: When you use a promo code, the driver generally only sees that a discount has been applied to the ride, not the name of the code or the specific promotion, nor does it typically share your gender identity with them.
General Privacy Policies: According to Lyft's privacy policy, the company does not share your private information (such as gender identity) with drivers.
In-App Name: You can set your preferred name in the app, which is what the driver will see, rather than your legal name.
While the promotion is publicly marketed as a supportive gesture for the trans community, the technical application of the code within the app is designed to be confidential between you and Lyft.
