Cookie Policy
Effective date: May 10, 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. The only cookie set
when you browse the marketing website is scntnms_consent,
which stores your cookie preferences across this site and the product
website — see Section 4 below.
4. Essential Cookies and Preference Storage
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. This section also covers the cross-site
scntnms_consent cookie, which is set by the marketing website
and read by the product website to remember your cookie preferences across
both sites.
| Name | Provider | Purpose | Type | Duration |
|---|---|---|---|---|
| Cognito session cookies | AWS Cognito | Authentication and session management | Cookie | Session / up to 1 hour |
scntnms_consent | Scantonomous | Remembers your cookie preferences across the marketing and product sites. | Cookie (parent domain, e.g. .scantonomous.ai) | 1 year |
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
A cookie banner appears the first time you visit our marketing site. You
can choose to allow only essential cookies or also enable performance
monitoring. Your choice is recorded as a
scntnms_consent cookie on the parent domain and is honored automatically
by the product website — you won't be asked twice.
If you arrive at the product website directly (for example through a sign-in or invitation link) without first visiting the marketing site, performance monitoring stays off until you record a preference. You can record one at any time from Profile → Cookies in the product website, or from the Cookie preferences entry in the user menu. 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. Clearing the scntnms_consent cookie or visiting
the marketing site in a fresh browser will bring the banner back.
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.
Approved AI model providers used for AI Scan features do not set cookies or browser storage through the marketing website or product website. For information about AI provider processing, see our Privacy Policy.
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.
