This Cookie Policy explains how EngMetric ("we", "us", or "our") uses cookies and similar tracking technologies when you visit our website. It should be read alongside our Privacy Policy.
1. What Are Cookies?
Cookies are small text files that are placed on your device (computer, tablet, or smartphone) when you visit a website. They are widely used to make websites work more efficiently, provide a better user experience, and give website owners useful information about how their site is being used.
Cookies can be "first-party" (set by the website you are visiting) or "third-party" (set by a service used by the website, such as an analytics provider). They can also be "session" cookies (deleted when you close your browser) or "persistent" cookies (remain on your device for a set period).
2. Cookies We Use
We use three categories of cookies on EngMetric:
| Category | Purpose | Consent Required |
|---|---|---|
| Essential | Site functionality, authentication, security | No (always active) |
| Analytics | Usage statistics and performance monitoring | Yes |
| Error Tracking | Bug detection and stability improvement | Yes |
We do not use advertising or marketing cookies. We do not track you across other websites, and we do not sell your data to third parties.
3. Essential Cookies (Always Active)
These cookies are necessary for the website to function and cannot be switched off. They are usually set in response to actions you take, such as logging in, setting your preferences, or filling in forms.
| Cookie | Purpose | Duration |
|---|---|---|
| authjs.session-token | Keeps you logged in across pages | Session / 30 days |
| authjs.csrf-token | Protects against cross-site request forgery | Session |
| authjs.callback-url | Redirects you after login | Session |
| cookie-consent | Remembers your cookie preferences | Persistent (localStorage) |
| theme | Remembers your light/dark mode preference | Persistent (localStorage) |
You can block essential cookies in your browser settings, but some parts of the site may not work as expected.
4. Analytics Cookies (Requires Consent)
These cookies help us understand how visitors interact with our website by collecting and reporting information anonymously. They are only activated if you click "Accept All Cookies" on our consent banner.
4.1 Google Analytics
We use Google Analytics to understand website usage and traffic patterns. Google Analytics uses cookies to collect information such as:
- Pages visited and time spent on each page
- How you arrived at our site (search engine, direct link, referral)
- General location (country/city level, based on IP address)
- Browser type, device type, and screen resolution
| Cookie | Purpose | Duration |
|---|---|---|
| _ga | Distinguishes unique users | 2 years |
| _ga_* | Maintains session state | 2 years |
Google Analytics data is processed in accordance with Google's Privacy Policy. We have IP anonymisation enabled, so your full IP address is never stored by Google.
4.2 Vercel Analytics
We use Vercel Analytics for performance monitoring and page load metrics. Vercel Analytics is privacy-friendly and does not use cookies for tracking. It collects aggregated, non-personally-identifiable performance data.
5. Error Tracking (Requires Consent)
We use Sentry to capture and fix bugs, improving the stability of our platform. Sentry collects error reports including:
- JavaScript errors and stack traces
- Browser and device information
- The page URL where the error occurred
Sentry does not track your browsing behaviour and is only activated with your consent. For details, see Sentry's Privacy Policy.
6. Google Consent Mode
We use Google Consent Mode v2 to ensure that Google Analytics respects your cookie preferences:
- If you decline cookies: Google receives no identifying data. Analytics tags may still load, but no cookies are set and no personally identifiable information is transmitted.
- If you accept cookies: Standard Google Analytics data collection applies, including the cookies listed in Section 4.1.
7. Managing Your Cookies
You have full control over which non-essential cookies are active on our site. You can manage your preferences in several ways:

- Customize: Choose individual categories
7.2 Cookie Settings Page

7.3 Browser Settings

- Block all cookies or only third-party cookies
- Set preferences for specific websites
Please note that blocking all cookies may affect the functionality of our website and other sites you visit.
8. Third-Party Cookies
Some cookies on our site are set by third-party services that we use. We do not control these cookies. The third-party services we use are:
| Service | Purpose | Privacy Policy |

- Analytics cookies: Up to 2 years (Google Analytics default)
- Preference cookies: Persistent until you clear your browser data
10. Global Privacy Control
We recognise and honour the Global Privacy Control (GPC) signal sent by your browser. When we detect a GPC signal:
- Non-essential cookies and analytics tracking will not be loaded
- No additional action is required from you
- The signal is treated as a valid opt-out request under applicable privacy laws (including CCPA/CPRA and UK GDPR)
