Last updated: August 26, 2026
1. What Are Cookies?
Cookies are small data files placed on your computer or mobile device when you visit a website. They help us understand how our site is used, keep you signed in, remember your preferences, and improve your experience.
Our site may use both session cookies (which expire when you close your browser) and persistent cookies (which remain until they expire or you delete them).
We use two categories of cookies: (1) first-party cookies, served directly by DataExpandr; and (2) third-party cookies, served by our service providers, which may recognize your device when it visits other websites.
2. Cookies We Use
The table below describes the cookies and similar technologies used on dataexpandr.com.
| Type | Cookie / Technology | Purpose | Duration |

| Essential | dx_session | Authenticates your session after login. HttpOnly, SameSite=Lax, Secure in production. Required for the platform to function. | 24 hours (up to 30 days with "Remember me") |
| Essential | dx_cookie_consent | Stores your cookie consent preference (accept or reject) in localStorage so we don't re-prompt you on every visit. | 1 year |
| Analytics | Umami (cookieless) | Privacy-friendly website analytics that collects aggregate page views, referrers, and device type. Umami does not use cookies, does not collect personal data, and does not track you across sites. | N/A — no cookies set |

3. Other Technologies
Browser Web Storage (localStorage). We use localStorage to persist your cookie consent preference and certain UI state. Unlike cookies, localStorage data is not sent to our servers with each request. You can clear localStorage through your browser's developer tools or settings.
Web Beacons. HubSpot forms may use web beacons (pixel tags) on our contact and demo pages to measure form engagement. These do not collect personal data beyond what you voluntarily submit in the form.
4. What We Do Not Use
- We do not use third-party advertising cookies or retargeting trackers.
- We do not use session-replay or screen-recording technologies.
- We do not use Flash cookies or Flash local shared objects.
- We do not use social media login cookies or social sharing trackers.
- We do not sell or share cookie data for cross-context behavioral advertising.
5. Your Choices
Cookie consent banner. When you first visit dataexpandr.com, a cookie consent banner lets you accept all cookies or reject non-essential cookies. Your choice is stored for one year. You can change it at any time:
Browser settings. Most browsers let you block or delete cookies. Consult your browser's help documentation for instructions. Blocking essential cookies may prevent you from signing in or using the platform.
HubSpot opt-out. You can block the hubspotutk cookie by rejecting non-essential cookies via our consent banner, or by configuring your browser to block third-party cookies.
6. Changes to This Policy
We may update this Cookie Policy from time to time. Changes will be reflected by updating the "Last updated" date above. Continued use of the site after changes constitutes acceptance.
