Truckline Privacy Policy

This policy covers the Truckline app for iPhone (the “App”), made by Single Track Apps LLC (“we”). The short version: what you say to your truck is processed on your iPhone, we don’t run ads or third-party analytics, and we don’t sell your data.

Your Rivian account

When you sign in, your Rivian password is sent only to Rivian and is never stored by the App. The session that Rivian returns is kept in your iPhone’s Keychain. The App uses it to read your vehicle’s status (such as battery, range, location, lock state, and current trip) and to send destinations and trips to your vehicle when you ask.

Truckline is an independent app. It is not affiliated with or endorsed by Rivian.

Voice and speech

The App listens through your microphone only while you are talking to your truck. Speech recognition and conversation understanding run on your iPhone, using Apple’s on-device models. Your voice and transcripts are not sent to us or to any cloud AI service.

Contacts and calendar

If you give permission, the App reads your contacts and calendar on your iPhone, only when you ask for a place such as “Mary’s house,” “my next appointment,” or “my hotel.” Only the place you confirm is sent to your vehicle.

Location

The App uses your vehicle’s location, and while you are using the App, your iPhone’s location, to find stops near you and along your route.

Place search

To find stops, the App sends your search, along with your location or route, to Apple Maps. If you subscribe to Enhanced Search, searches go to Google Maps Platform instead, always through a server we run. That server checks your subscription and counts requests to prevent abuse, and doesn’t keep your searches. Google handles these requests under the Google Privacy Policy.

Place names

To recognize the names of places you ask for, the App comes with a list of parks, landmarks, and towns, and downloads street and business names for the areas you drive in: around your vehicle, your home, your recent destinations, your route, and towns you name. These come from a server we run, in squares about 20 miles across, so the server learns which squares were requested but not where you are within them. The requests don’t include your Rivian account or any other identifier. Our hosting provider, Cloudflare, keeps routine request logs, which can include your IP address, for a short time for troubleshooting.

Subscriptions

Purchases are handled by Apple. We never see your payment details.

Diagnostics

Logs and conversation transcripts stay on your iPhone. They reach us only if you choose to email them to support.

Changes

We may update this policy from time to time by posting a new version on this page.

This privacy policy is effective as of 2026-10-25.
