Privacy

We collect what's needed to do the work: your email, the vehicle details you give us, the files you upload, and your payment, which is processed by Stripe — we never see your card number.

Your calibration file contains your vehicle's VIN. We use it only to tune your vehicle. Files are deleted 90 days after your last order or revision. We don't sell or share customer information, and we don't use your vehicle or your name in marketing without asking.

The site sets one cookie to keep your session and form secure. We don't run third-party trackers or advertising pixels. Email support@transmissiontunes.com to ask what we hold or to have it deleted.
