Cookie Policy
Effective date: March 28, 2026
1. What Are Cookies
Cookies are small text files that a website places on your device when you visit. They are widely used to make websites work more efficiently and to provide information to site owners. Cookies can be "persistent" (they remain on your device until they expire or you delete them) or "session" cookies (they are deleted when you close your browser).
We also use similar technologies such as local storage, which works like cookies but stores data differently in your browser. When we say "cookies" in this policy, we mean all of these technologies.
2. Cookies We Use
The following table lists the cookies set on senderZ.com and what each one does.
| Cookie | Type | Purpose | Duration |
|---|---|---|---|
| session | Functional | Maintains your authenticated session when you are logged in to the portal or dashboard. | 14 days |
| cookie_consent | Functional | Stores your cookie preferences so we do not show the consent banner on every visit. | 1 year |
| oauth_state | Functional | Temporary token used during the sign-in flow to prevent cross-site request forgery attacks. | 10 minutes |
| _ga | Analytics | Google Analytics — distinguishes unique visitors to help us understand how many people visit the site. | 2 years |
| _gid | Analytics | Google Analytics — distinguishes visitors for a single day of tracking. | 24 hours |
| _gat_gtag | Analytics | Google Tag Manager — used to throttle request rates to Google Analytics. | 1 minute |
3. Functional Cookies
Functional cookies are essential for the website to work correctly. They handle things like keeping you logged in during a session, remembering your cookie preferences, and securing the sign-in process. Because these cookies are strictly necessary, they cannot be disabled. Rejecting non-essential cookies through our banner does not affect functional cookies.
4. Analytics Cookies
We use Google Analytics 4 (GA4) and Google Tag Manager (GTM) to understand how visitors use senderZ.com. This helps us improve the site and understand which content is most useful. Analytics cookies are only loaded after you give consent through the cookie banner.
The data collected by GA4 includes pages visited, time on site, approximate geographic location (country or region level), browser type, and device type. We have configured GA4 with IP anonymization enabled — your full IP address is never stored. We do not use analytics cookies inside the authenticated portal or dashboard.
5. How to Control Cookies
You have several ways to control which cookies are set:
- Cookie banner: When you first visit senderZ.com, a banner allows you to accept all cookies, reject non-essential cookies, or customize your preferences.
- Cookie Settings link: You can reopen your preferences at any time using the "Cookie Settings" link in the footer of any page on senderZ.com.
- Browser settings: Most browsers allow you to block or delete cookies through their privacy or security settings. Note that blocking all cookies may affect the functionality of the site, including the ability to stay logged in.
- Google Analytics opt-out: You can install the Google Analytics Opt-out Browser Add-on to prevent GA4 from collecting data on all sites you visit.
6. Third-Party Cookies
The only third-party cookies on senderZ.com are those set by Google Analytics and Google Tag Manager, which are described in section 4 above. We do not use any advertising or retargeting cookies. We do not share your data with advertising networks or use cookies to build advertising profiles.
Our authentication provider, Clerk, may set cookies related to your login session when you sign in to the portal or dashboard. These are functional cookies and are covered by Clerk's own privacy policy.
7. Changes to This Policy
We may update this Cookie Policy from time to time as the cookies we use change or as regulations evolve. When we make changes, we will update the effective date at the top of this page. If the changes are significant, we will display a notice on the website. Your continued use of senderZ.com after any changes means you accept the updated policy.
