Privacy Policy

Last updated: 23 May 2024

Welcome to Rouast Labs! Your privacy is important to us, and we are committed to protecting it. This Privacy Policy explains how we collect and use your personal information when you use our services, including our website (, VitalLens API, and VitalLens App. By using any of our services, you agree to the terms outlined in this policy.

1. Information We Collect and How We Collect It

1.1 Website

We use the following third-party service to collect data when you visit our website:

  • Google Analytics: We collect data on website usage, visitor interactions, and device information.

1.2 VitalLens API

  • Personal Information: We collect information provided when you register to receive an API Key, including your name, company, job title, and email address.
  • API Usage Data: We collect metadata logs of your API requests including timestamps, API Key, and whether they finished in success or error. We temporarily keep the payload data from your API requests in memory while required for processing; this data as well as the returned results are disposed of after the API call finishes.

1.3 VitalLens App

Most importantly, we do not collect your video or vitals data through the VitalLens App.

Beyond that, we use the following third-party services which collect data unrelated to your video or vitals:

  • Google AdMob: Unless you have paid to remove ads and opted out of all ads, we use Google AdMob for displaying advertisements. AdMob collects data for ad targeting (unrelated to your video and vitals). Unless you have opted out of this behavior, AdMob also employs a unique identifier associated with your device.
  • Google Firebase Analytics: We use Google Firebase Analytics to collect analytical data on how our app is performing. This includes information about app usage, user interactions, and device information (again, unrelated to your video or vitals).

As a third party collecting information on our behalf, Google is required to provide the same or equal protection of user data as stated in this Privacy Policy. View Google's privacy policy at

We never share your data with any other third parties.

3. Data Retention and Your Privacy Choices

  • Data Retention: We retain data collected by Google associated with cookies, user identifiers, or advertising identifiers for a period of 2 months. We indefinitely retain API usage and log data for operational and billing purposes. We do not retain any data on API request payloads or returned results.
  • Opting Out: You can opt out of Google Analytics tracking using the Google Analytics Opt-out Browser Add-on. For AdMob, we will ask if you want to opt out of tracking related to ads.
