Session analysis runs entirely in your browser; your lap-timer file and GPS trace are not uploaded. When you buy a debrief, the numeric verdict (speeds, times, scores — not your GPS trace) is sent to our API and processed in memory to generate the debrief. By default it is not stored: the debrief lives at its receipt URL and nowhere else. We keep: a per-purchase use counter keyed to your Stripe checkout session, and — if you join the waitlist — your email address, used for one launch email. Payment details are handled by Stripe and never touch our servers.

When your debrief is ready we also email a copy to the address you gave Stripe at checkout, so reading it later does not depend on keeping the receipt link. Sending it means the debrief text — still never your GPS trace — passes through Resend, the service that delivers our email. We do not add that address to any list and send nothing else to it.

If you choose to save a debrief to an account, we store that debrief and its numeric verdict against your email address so you can read it again on another device. This is entirely optional — the free analyzer and checkout never require an account, and a signed-out purchase behaves exactly as described above. Your GPS trace is still never uploaded, saved or not. You can delete your account and every debrief saved to it at any time from your account page; deletion is immediate and removes the sign-in record too.

This site sets no analytics cookies and runs no trackers. The analyzer page loads Google reCAPTCHA to verify that checkout requests come from a real browser rather than a script. The analyzer and account pages also load the Firebase SDK from Google, which is what sends and completes the sign-in link for the optional account described above. Nothing we load from Google is used for advertising or analytics, and no other page loads anything from Google.

TENTHS is an analysis tool operated by Another One, LLC. All outputs — including reference laps, corner speeds, lean-angle figures and debrief text — are GPS-derived or physics-simulation estimates, provided for entertainment and training-planning purposes, without warranty of accuracy or fitness. Motorcycle track riding is inherently dangerous: you alone are responsible for your riding decisions, and nothing produced by this tool is an instruction to ride faster, brake later, lean further, or exceed your limits, your organization's rules, or the guidance of professional instructors. Debriefs are digital services delivered immediately upon generation; a purchase whose debrief cannot be delivered and verified is not consumed. Questions and refund requests: hey@ridetenths.app.
