Cookie Policy
Effective Date: February 13, 2026
1. What Are Cookies
Cookies are small text files that websites place on your device (computer, tablet, or mobile phone) when you visit them. They are widely used to make websites work more efficiently, to remember your preferences, and to provide information to website owners.
First-party cookies are set by the website you are visiting. Third-party cookies are set by a service other than the website you are visiting, such as an analytics provider.
In addition to cookies, we use similar technologies such as browser local storage to store authentication information. This Cookie Policy covers both cookies and these similar technologies.
2. How We Use Cookies
ShippingCostCalculator.com uses cookies and similar technologies for two purposes:
Analytics. We use Google Analytics to understand how visitors interact with the Service, which pages are most popular, and how we can improve the user experience.
Authentication. We use browser local storage (not a cookie) to keep you logged in to your account between visits.
We do not use cookies for advertising, retargeting, or social media tracking.
3. Cookies and Technologies We Use
The table below lists the specific cookies and storage technologies used on the Service:
| Name | Category | Type | Purpose | Duration |
|---|---|---|---|---|
jwt | Essential | First-party (localStorage) | Stores your authentication token to keep you logged in | Until you log out or token expires (7 days) |
_ga | Analytics | Third-party (Google) | Distinguishes unique users for analytics | 2 years |
_ga_<ID> | Analytics | Third-party (Google) | Maintains session state for Google Analytics | 2 years |
_gid | Analytics | Third-party (Google) | Distinguishes unique users for analytics | 24 hours |
4. Essential Storage
When you log in to ShippingCostCalculator.com, we store a JSON Web Token (JWT) in your browser’s local storage. This token is essential for the Service to recognize you as a logged-in user.
It contains only your user identifier and session expiration—no tracking or advertising data.
It is automatically removed when you log out.
It is not a cookie and is not sent to third parties.
You can clear it at any time by logging out or clearing your browser’s site data.
5. Analytics Cookies
We use Google Analytics to collect anonymized data about how visitors use the Service. Google Analytics sets cookies on your browser to distinguish users, track sessions, and measure page views.
The data collected includes pages visited, time spent on pages, referring URLs, browser type, and device information. This data is aggregated and does not personally identify you.
Google processes this data in accordance with Google’s Privacy Policy. You can opt out of Google Analytics by installing the Google Analytics Opt-out Browser Add-on.
6. How to Manage Cookies
Most web browsers allow you to control cookies through their settings. You can typically set your browser to block or delete cookies, or to alert you when a website attempts to set a cookie. The following links provide instructions for the most common browsers:
Please note that blocking or deleting cookies may affect the functionality of the Service. If you block analytics cookies, we will not be able to collect anonymized usage data, but the Service will continue to function normally.
To opt out of Google Analytics specifically, you can install the Google Analytics Opt-out Browser Add-on.
7. Do Not Track
Some web browsers offer a “Do Not Track” (DNT) setting that sends a signal to websites requesting that your browsing activity not be tracked. There is currently no universal standard for how websites should respond to DNT signals.
We do not currently alter our data collection practices in response to DNT signals. However, you can opt out of analytics tracking at any time using the methods described in Section 6 above.
8. Changes to This Cookie Policy
We may update this Cookie Policy from time to time to reflect changes in the cookies and technologies we use. The “Effective Date” at the top of this page will be updated to reflect the date of the most recent changes.
For material changes, we will make reasonable efforts to provide notice on the Service. Your continued use of the Service after any changes constitutes your acceptance of the revised Cookie Policy.
