Privacy Notice

Last updated August 5, 2017

Dear Coastline user,

Your privacy and trust are critical to us at Coastline. The goal of this letter is to share with you how we treat your drives and the steps we take to ensure your privacy. We hope you’ll take a few minutes to read this, and if you have any questions that aren’t answered here, please reach out at and we’ll get right back to you.

We protect your privacy in two important ways:

  1. Communication – Notices like this letter intend to describe in plain language how we use and protect your drive recordings so you can decide if our standards are in line with yours.
  2. Technology – We make every reasonable attempt to protect your identity and drives, as outlined below.

How Coastline works

Step 1
The Coastline app allows you to record your drives so we can provide scoring and coaching to help you learn skills and become a better driver.

The app records video, GPS location and speed data, and 3D-accelerometer data that measures the vibrations and forces on your phone while you’re driving.

Coastline does not record audio.

Step 2
A summary of what was recorded is uploaded right away to our secure servers on the cloud, and the complete data is uploaded after your drive over the cell network, or stored on your phone until you connect to WiFi, depending on your settings.

Step 3
Once your drive is uploaded, our instructors and AI analyzes the video and sensor data to score your drive and provide coaching tips.

We may also use portions of your drives for other purposes, as outlined below.

How we use your drives

Our goal help you become a better, safer driver. One way we do that is to provide coaching and scoring, which requires people and computer systems to access your drives. Here are some examples of those people and systems:

1. Driving instructors, who may be independent contractors, may review and provide feedback on drives from many users.
2. Other contractors or service providers, who may help with tasks such as editing video clips, classifying objects like stop signs, or partners who score aspects of drives for us.
3. Technology service providers, who may store or process data.

In each case, our goal is to share the minimum amount of drive data to provide the services we offer to you.

How we use anonymized drives

Autonomous vehicles represent the biggest transformation in mobility since the invention of the automobile. One of the key ingredients to bringing self-driving cars to market is millions of miles of driving data.

We may use your drives in the following ways:

1. To improve our models, thus improving the accuracy of our coaching AI, and our real time collision avoidance alerts for you and everyone who uses Coastline. Your drives are literally reducing car crashes all around the world.
2. We may license portions of anonymous driving data to partners. For example, a company working on a fully self-driving car who is looking for instances of pedestrians at crosswalks may license that data from Coastline.

You are welcome to opt out of sharing your drives with partners at any time by visiting the Settings screen of the app. You are not able to opt out of sharing drives with Coastline as our service does not work if we cannot score and analyze your drives. If you don’t want to share your drives with Coastline, please don’t use the app.

Deleting your drives

You have an option within the app to delete a drive. When you select that option, the drive is deleted from your device and our servers.

It is possible that by the time you delete the drive, it will have been reviewed by a driving instructor and they may have made a copy of all or part of that drive for coaching purposes. We will try to maintain a link between the original drive and that clips included in the feedback we provide, such that we can delete those copies too, but there are several ways in which that link or delete order could be lost, so it’s possible that parts or all of that drive will exist somewhere despite our efforts.

Also, if we have made an anonymized copy of your drive and shared it with a partner, the anonymization will necessarily remove that link and the anonymized copy will persist. We will continue to look for ways to enhance your privacy with regards to deleting drives, but if this is a concern for you we’d recommend opting out of anonymous data sharing.

Other data collection

Similar to other apps and websites, there are a few ways we collect data from app users and site visitors.

Browsing data
We collect the sort of data typically provided by web servers, such as IP address, pages visited on our site, browser type etc. We do this so that we can better understand what people are doing on our site so we can make our site and services better. That type of data is generally non-personally identifiable, unless you are logged in or you provide personally identifiable information during the browsing session, such as by filling out a form.

A cookie is a string of information that a website stores on a visitor’s computer, and that the visitor’s browser provides to the website each time the visitor returns. We use cookies to help us identify and track visitors, their usage of our website, and their website access preferences. If you’d prefer not to be accept cookies, you can set your browser to refuse cookies.

Third party services
We use several third party services to learn about how people engage with our site and apps. These include analytics services, crash reporting, user login management, and payment services, among others. Each service has its own privacy policy, and we try to ensure we are using services with approaches to privacy that match our own.

Profile/login/payment information
When you create an account, login, or provide payment information, you are providing us with personally identifiable information. We attempt to collect only what we need to provide you with a great service, and we guard this information as best we can, using the best third party services we can find. We share some of this information as needed with employees, contractors, service providers, and affiliate organizations, who reside inside and outside the US, for the purpose of providing a great service. As with anything you do on the internet, providing this information to us comes with risks, as even the best technology can be hacked or otherwise compromised.

Other ways data can be shared

In the even that Coastline is acquired or goes bankrupt, all data we collect will likely be transferred to the new owners, subject to this privacy notice and our terms of service.

There are situations in which we could be legally or ethically required to share personal data with third parties. For example, if we are served a valid and legally enforceable request by law enforcement, or if we have reason to believe that you or someone else is in serious danger. We won’t take these situations lightly, and will have your best interests in mind when we decide how to respond in each case.

Thank you for reading, and we hope you enjoy using Coastline!
