This Cookie Policy explains how Opsite Solutions LLC ("Opsite," "we," "us," or "our") uses cookies and similar tracking technologies when you visit our website at useopsite.com or use our construction management platform at app.useopsite.com (collectively, the "Service").
By using our Service, you consent to the use of cookies and similar technologies as described in this policy. You can manage your cookie preferences as explained in Section 6 below.
Cookies are small text files that are stored on your device (computer, tablet, or mobile phone) when you visit a website. They are widely used to make websites work more efficiently, provide a better user experience, and give website owners information about how their site is being used.
Set by Opsite directly when you visit our Service. These are essential for the Service to function properly.
Set by our partners and service providers (such as analytics services) to help us understand how you use our Service.
Temporary cookies that are deleted when you close your browser. Used to maintain your session while using the Service.
Remain on your device for a set period or until you delete them. Used to remember your preferences across sessions.
These cookies are required for the Service to function and cannot be disabled. They include:
| Cookie Name | Purpose | Duration |

| next-auth.session-token | Maintains your authenticated session | Session / 30 days |
| next-auth.csrf-token | Prevents cross-site request forgery attacks | Session |
| next-auth.callback-url | Stores redirect URL after authentication | Session |

We use privacy-preserving analytics to understand how visitors interact with our Service. Our analytics providers are cookieless and do not collect personal information:
| Provider | Method | Purpose |
|---|---|---|
| Vercel Analytics | Cookieless; no PII | Page views, performance metrics, error tracking |
| Plausible Analytics | Cookieless; no PII; EU-hosted | Aggregated page views, referrer, country |
Analytics data is aggregated and does not personally identify you. No third-party advertising cookies are set by these providers.
When you connect third-party services, they may set their own cookies:
| Integration | Purpose | Privacy Policy |
|---|---|---|
| Intuit QuickBooks | OAuth authentication, invoice sync | View Policy |
| Google Maps | Address autocomplete, map display | View Policy |
| Stripe | Payment processing, subscription management | View Policy |
In addition to cookies, we may use these similar technologies:
We use browser local storage to save your preferences and application state (such as dashboard layout, filter settings, and form drafts) to provide a seamless experience across sessions.
Temporary data storage that is cleared when you close your browser tab. Used for maintaining state during your current session (e.g., unsaved form data, navigation history within the app).
Small transparent images embedded in emails or web pages to track whether content has been viewed. We use these to measure email open rates and improve our communications.
Legitimate Interest: Essential cookies are necessary for the Service to function. Without them, you would not be able to log in, maintain your session, or use core features. These cannot be disabled.
Legitimate Interest: Our analytics providers are configured to operate without cookies and without collecting personal information. We rely on legitimate interest under GDPR Article 6(1)(f) for aggregated, anonymized analytics.
Consent: For cookie-based functional features we rely on your consent. You can withdraw consent at any time by adjusting your browser settings. Where required by applicable law (EU/UK/Switzerland), we present a consent banner before any non-essential cookies are set.
Most web browsers allow you to control cookies through their settings. Here are links to manage cookies in popular browsers:
Warning: Disabling essential cookies will prevent you from using the Opsite platform. You will not be able to log in or access your construction management data. Disabling functional cookies may degrade your experience (e.g., preferences won't be saved).
Some browsers have a "Do Not Track" (DNT) feature that sends a signal to websites requesting that your browsing not be tracked. Our Service does not respond to DNT signals (which have been deprecated by most major browsers).
However, we honor the Global Privacy Control (GPC) browser signal as a valid opt-out of any sale or sharing of personal information under the California Consumer Privacy Act and the California Privacy Rights Act, consistent with the California Attorney General's enforcement position in People v. Sephora USA (2022). When we detect a GPC signal, we automatically apply your opt-out preference for the current and future visits from the same browser.
We may update this Cookie Policy from time to time to reflect changes in technology, law, or our business practices. When we make material changes, we will update the "Last Updated" date at the top of this page and, where appropriate, notify you via email or through the Service.
