LightShow for Tesla. Last updated 14 October 2026.

LightShow turns a song into a light show for your Tesla. This page says what it holds, why, and how to make it go away. It covers the website and the iPhone app.

What you give it

• A song. Either a file you upload, or a few words you type so the AI writes one for you.
• On the website, an account if you choose to sign in. Signing in goes through Google and tells us your name and email address. The app has no sign-in at all.

What happens to the song

The song goes to our generator, which runs on Google Cloud in the US. The generator listens to it, plans the show and writes the files your car plays. Three outside services take part:

• Google Gemini hears the audio and writes a short description of the music. When you ask for an original song, Google's Lyria writes it from your words.
• A language model plans the choreography. It gets a written summary of the music and the description above, never the audio itself. Today that is xAI, with Anthropic or OpenAI as the fallback.

The song and the generated files are deleted from the server within a day. The copies you keep live on your phone or in your browser, and those are yours to delete.

What it stores

• A ledger line per show: the name of the show, when it was made, how long it is, and what it cost us to make. On the website it hangs off an anonymous id in a cookie, or your account if you signed in.
• If you signed in on the website: the name and email address Google gave us.
• In the app: your shows, saved on the phone where the Files app can see them, and a count of show credits. Nothing about you leaves the phone except what the next two sections say.

Usage numbers

PostHog, in the US, counts what people do: pages opened, songs uploaded, shows generated and downloaded, the kind of phone or browser and the country it came from. On the website a signed-in user is recorded by name. In the app it is an anonymous id. Nothing is sold and there are no advertisers.

Feedback

A message you send from the feedback button or the support page reaches Ben over Telegram, with the page you were on, your browser, your IP address and the city it points to. That is so a bug report can be matched to what went wrong. If you are not signed in you can add an email address, and it is used only to answer you. A copy of each message is kept in a log on our server so nothing gets lost on the way.

Who else touches it

• Vercel, which runs the website
• Neon, which runs the database
• Google Cloud, which runs the generator, in the US
• Clerk, which handles sign-in on the website
• Google Gemini and Lyria, xAI, Anthropic and OpenAI, as above
• PostHog, for the usage numbers

That is the whole list.

Deleting everything

• In the app: delete the app. The shows and the credit count go with it.
• On the website: write from the support page and say you want your account gone. The account and its ledger lines are deleted.

Children

LightShow is made for people who own a car. It is not aimed at children.
