Cookie Policy
Effective date: April 1, 2026
1. Introduction
This Cookie Policy explains how Scantonomous (“Company,” “we,” “us”) uses cookies and similar browser storage technologies on the Scantonomous public marketing website and the authenticated Scantonomous product website at app.scantonomous.ai (“Service”).
2. What Are Cookies
Cookies are small text files placed on your device by a website. Similar technologies include localStorage and sessionStorage, which allow websites to store data locally in your browser. We use both cookies and browser storage to operate the Service.
3. Marketing Website
The public marketing website does not use advertising cookies, third-party tracking cookies, or analytics cookies. No cookies are set when you browse the marketing website.
4. Product Website — Essential Cookies
The authenticated product website uses strictly necessary cookies and browser storage to maintain authentication, session state, and core product functionality. These cannot be disabled without breaking the Service.
| Name | Provider | Purpose | Type | Duration |
|---|---|---|---|---|
| Cognito session cookies | AWS Cognito | Authentication and session management | Cookie | Session / up to 1 hour |
scntnms-cookie-consent-v1 | Scantonomous | Stores your cookie preference choice | localStorage | Persistent |
scntnms-theme | Scantonomous | Stores your dark/light mode preference | localStorage | Persistent |
scntnms_auth_redirect | Scantonomous | Preserves your intended destination during sign-in | sessionStorage | Tab close |
5. Product Website — Performance Cookies
If you opt in through the cookie banner or your profile settings, we use AWS CloudWatch Real User Monitoring (RUM) to measure frontend errors and page performance. These cookies are disabled by default and are only set after you explicitly allow performance monitoring.
| Name | Provider | Purpose | Type | Duration |
|---|---|---|---|---|
cwr_s | AWS CloudWatch RUM | Session identifier | Cookie | Session |
cwr_u | AWS CloudWatch RUM | Anonymous user identifier | Cookie | 30 days |
cwr_c | AWS CloudWatch RUM | Credential storage | localStorage | Persistent |
cwr_i | AWS CloudWatch RUM | Identity metadata | localStorage | Persistent |
The names above are base prefixes. AWS RUM may also set
environment-specific variants with an app monitor ID suffix (e.g.
cwr_s_<id>). These serve the same purposes listed
above.
We do not use advertising cookies, social media tracking pixels, or third-party analytics services such as Google Analytics.
6. Managing Your Preferences
When you first sign in to the product website, a cookie banner appears at the bottom of the page. You can choose to allow only essential cookies or also enable performance monitoring.
You can change your preference at any time by navigating to Profile → Cookies in the product website. Disabling performance cookies immediately stops monitoring and clears all performance-related cookies and storage from your browser.
You can also delete cookies through your browser settings. Note that removing essential cookies will sign you out and may affect core product functionality.
7. Third-Party Services
As of the effective date of this policy, the third-party services that set cookies or browser storage through the product website are:
- AWS Cognito (Amazon Web Services) — authentication and session management
- AWS CloudWatch RUM (Amazon Web Services) — frontend performance monitoring (opt-in only)
Both services operate under the AWS Privacy Notice.
8. Changes to This Policy
We may update this Cookie Policy from time to time. We will notify customers by email before material changes take effect and will post the updated policy on this page with a revised effective date. Continued use of the Service after changes take effect constitutes acceptance.
