Cookie Policy

1. What Are Cookies

Cookies are small data files that a website stores on your computer or mobile device. When you visit the Appraiser Guru platform, the server sends a cookie to your browser, which then stores it locally. On subsequent visits, the browser automatically sends the cookie back to the server.

Cookies serve important functions: they remember your login information so you don't have to sign in every time you visit, they keep you secure by preventing unauthorized access, and they help the platform function properly. Cookies are a standard web technology and are used by virtually all websites.

Cookies cannot run programs or directly access your files. They are not viruses or spyware. You control whether cookies are stored through your browser settings.

2. Essential/Strictly Necessary Cookies

2.1 What They Are

Essential cookies (also called "strictly necessary" cookies) are required for the Appraiser Guru platform to function properly. These cookies are not based on your consent and cannot be disabled. Without these cookies, the platform would not work.

2.2 Types of Essential Cookies

• Authentication Session Tokens: When you log in, Supabase (our authentication provider) sets a cookie containing an encrypted session token. This proves you are logged in and allows the platform to display your account, reports, and data. Without this cookie, the system would require you to log in on every page or action.
• CSRF Protection Cookies: Cross-Site Request Forgery (CSRF) protection cookies prevent unauthorized third parties from tricking you into making unwanted actions on the platform (such as changing your password or deleting data without your knowledge).
• Load Balancing Cookies: When the platform is served from multiple servers, load-balancing cookies ensure your requests go to the same server consistently, maintaining session state and preventing redundant authentication.
• User Preference Cookies: These cookies remember your settings and preferences (such as theme selection, language selection, and notification preferences) so you don't have to reconfigure them on every visit.

2.3 Consent and Necessity

Essential cookies are set based on legitimate interest and technical necessity under applicable privacy frameworks, including GDPR. These cookies are strictly necessary for the Service to function and do not require separate consent. However, we are transparent about their use: without these cookies, the platform cannot authenticate your identity, maintain your session, or protect against security threats. If you block essential cookies in your browser, the platform will not function — you will be unable to log in, your data will not load, and actions will fail. We encourage you to review this policy so you understand exactly what cookies are in use and why.

3. Analytics

3.1 Vercel Web Analytics

As of October 2026, Appraiser Guru uses Vercel Web Analytics, a service of Vercel Inc. (which also hosts the platform), to count page views and understand which pages are used. It runs on every page of the public website and of the signed-in platform. We do not use Google Analytics or any advertising or cross-site tracking service.

3.2 What It Collects

Each time a page is viewed, a script from Vercel sends Vercel a record of the page view. Vercel's documentation lists what may be stored with each record: the time; the address of the page (inside the signed-in platform, the address can include the internal reference number of a report or order, but none of its contents); the referring page; filtered query parameters; approximate location (country, region and city); your browser, operating system and device type; and the script version.

We also record two events of our own: a click on a sign-up button on our pricing page (with the page, the plan shown and the button's position), and a completed waitlist sign-up (with the page and the name of the website that referred you). Neither event includes your email address or your name.

3.3 Cookies and Identification

Vercel's documentation states that Web Analytics does not use third-party cookies, that it tells visitors apart by a hash created from the incoming request, that this visitor session is discarded after 24 hours, and that the page views it records are not tied to any individual or IP address. These statements describe Vercel's service as Vercel documents it; the collection script is supplied by Vercel, not written by us. We use the results only as aggregated counts.

3.4 Your Choices

The platform does not currently offer a setting to turn Web Analytics off. Browser tools that block analytics scripts will stop the script from sending page views, and the platform works without it.

4. No Third-Party Advertising Cookies

4.1 No Advertisements

Appraiser Guru does not serve advertisements or promotional content to users. The platform is not ad-supported.

4.2 No Ad Tracking

Because the platform does not serve ads, we do not use third-party advertising cookies, retargeting cookies, ad network pixels or tracking beacons, or behavioral profiling for advertising purposes.

4.3 Your Data is Not Sold

Appraiser Guru does not sell your personal data to advertisers, data brokers, or third parties for marketing purposes. Your information is used solely to provide and improve the Service.

5. Managing Cookies in Your Browser

5.5 Impact of Blocking Cookies

If you block essential cookies from Appraiser Guru, the platform will not function properly. You may be unable to log in, your data may not load, actions may fail, your session may be terminated unexpectedly, and security protections may be compromised. We strongly recommend allowing essential cookies for tarnwick.com.

6. Cookie Retention and Expiration

6.1 Session Cookies

Session cookies are automatically deleted when you close your browser. These include temporary session identifiers and some preference cookies.

6.2 Authentication Tokens

Authentication session tokens follow Supabase's refresh cycle. By default, session tokens are refreshed automatically and remain valid for up to 24 hours of inactivity. If you are inactive for more than 24 hours, your session expires and you will need to log in again.

6.3 Analytics

We do not set analytics cookies. Vercel's documentation states that Vercel Web Analytics does not use third-party cookies and that its visitor session is discarded after 24 hours (see Section 3.3).

7. First-Party vs. Third-Party Cookies

7.1 First-Party Cookies

All cookies set by Appraiser Guru are first-party cookies, meaning they are set by the tarnwick.com domain only. These cookies are not shared with external websites or advertisers.

7.2 Third-Party Services

Appraiser Guru does use some third-party services (such as Supabase for authentication and Stripe for payments). These services may set their own cookies for their essential functions. Review their privacy policies:

• Supabase: supabase.com/privacy
• Stripe: stripe.com/privacy

8. Updates to This Policy

The Company may update this Cookie Policy at any time. If significant changes are made to cookie practices (such as adding new types of cookies), users will be notified via email at least 30 days before the changes take effect. Continued use of the platform after the effective date constitutes acceptance.
