Cookie Policy

This Cookie Policy explains how zeils-agent.com uses cookies and similar technologies, and how you can control them. It should be read together with our Privacy Policy.

The short version: we run a small number of cookies that keep the site working and tell us roughly which pages are read. We do not run advertising cookies, retargeting pixels, or cross-site trackers. The rest of this page names each category, says what it does, and shows how to turn cookies off in your browser.

What cookies are

Cookies are small text files placed on your device by a website you visit. They are widely used to make sites function, to remember preferences, and to gather basic usage information. Some cookies are set directly by a site, and others by third-party services the site relies on.

A cookie can live for the length of a single visit (a session cookie) or for a defined period measured in days or months (a persistent cookie). It carries a small identifier rather than the content you typed, and it is read back only by the site — or by the third party — that set it. Alongside cookies, sites sometimes use closely related tools such as local storage or pixels; where this policy says "cookies", it covers that same family of small identifiers.

zeils-agent.com is a reading resource about U.S. healthcare payment workflows — claims lifecycle, remittance data, and provider or payer portal integrations. It is not a portal you sign into and it is not a place where claim or payment data is entered. That keeps the cookie footprint narrow: what we set is here to run the pages and to understand which pages are read, not to build a profile of anyone who visits.

Cookies we use

Two categories, no advertising

We use a small number of cookies for core site functionality, such as remembering a session while you browse, and for basic analytics that tell us which pages are read. We do not use cookies for advertising, retargeting, or cross-site tracking. Each row below names one category, what it is for in plain terms, and how long it tends to stay on your device.

Necessary

Required for the site to operate and for security. They keep a session together while you move between pages, remember your consent choice, and support the basic protection that stops abuse of the site. The site cannot work as intended without them.

Session

until close

Analytics

Used in aggregate to understand page interest and site performance. They tell us which explanations are being read and where pages load slowly, so the resource can be edited to be clearer. They are not linked to an individual reader and are never used to compose a profile or target content.

Persistent

up to 13 months

Advertising

Not set on this site. We do not run advertising, retargeting, or cross-site tracking cookies, and we do not authorize any third party to build advertising audiences from visitors to zeils-agent.com. If this ever changes, this line and the section above it will be rewritten first.

Managing cookies

Your browser is the switch

You can control or delete cookies through your browser settings. Most browsers allow you to block cookies entirely or to be notified before a cookie is set. Blocking necessary cookies may affect how the site functions — a page may forget your place, and your consent choice may not be remembered.

If you write to zeils agent support with a question about cookie handling on a specific page, we can point at exactly which identifier is in play there.

Where to look

Chrome Settings, then Privacy and security, then Third-party cookies. The site data list lets you remove cookies for one site at a time.
Safari Settings, then Privacy, then Manage Website Data. You can remove everything, or step through the list and delete a single site.
Firefox Settings, then Privacy and Security, then Cookies and Site Data. Manage Exceptions sets a per-site rule if you want one domain blocked and another allowed.
Edge Settings, then Cookies and site permissions, then Manage and delete cookies and site data. The same panel clears what has been stored.

Third-party, changes, contact

The record on file

Three short notes that close this document: which external tools may set cookies, when this page gets rewritten, and where to send a question.

Third-party cookies: If the site embeds any third-party content or measurement tools, those providers may set cookies subject to their own policies. We choose providers with a minimal data footprint and do not authorize advertising use of any data collected through this site. Where an embed is optional, the surrounding page keeps working whether or not it loads.
Changes to this policy: We may update this policy if the cookies we use change. The effective date will be revised when material changes are made. A material change is one that adds a category of cookie, replaces the tooling behind an existing category, or changes what an existing cookie is used for. Editorial edits that only clarify wording do not reset the date.
Contact: Questions about this policy can be sent through the contact page at contact, by writing to 450 Serra Mall, Stanford, CA 94305, USA, or by email at [email protected]. Our phone line is open Monday to Friday, 9:00 AM – 6:00 PM at +1-650-723-2300.

Operator notes

Questions we get about cookies

Four notes from the support desk. Each one opens in place — the step line stays on screen so you can see which note you are reading.

Read pages

What do the analytics cookies actually tell you?

Aggregate only

We see how many times a page is opened, roughly where in the world the visit came from, and how long the page took to load. That is it. The data is aggregated before we look at it, so a single reader cannot be isolated from it. It is used to decide which explanation needs a rewrite and where a page is too slow to read comfortably.

Field note

You can block analytics cookies and the site keeps working; you simply disappear from our page counts.

Portal pages

Does anything here touch a Zelis portal session?

No. zeils-agent.com is a reading resource about U.S. healthcare payment workflows, and it does not host or proxy a Zelis portal session. If you follow an article that discusses a provider or payer portal, the browser never leaves this site or reaches a sign-in screen through it. When a question about an actual portal session comes in to zeils agent support, it is answered by the team on a per-account basis rather than by anything the site reads.

Field note

Articles about portal integrations are written for reading, not for pairing with a running session.

Consent

What does the on-site cookie choice actually change?

Stored locally

Your choice is kept in a necessary cookie on this site so we do not ask again on the next page. It records which categories you allowed and nothing else. Clearing cookies for zeils-agent.com removes the record, and the site asks again on your next visit. The consent record itself is never sent to a third party.

Field note

Blocking the necessary cookie means the prompt will not remember you; nothing else on the page breaks.

Records

Do you keep a log of who has read what?

No individual log

No. There is no per-reader log of pages viewed, and no profile is assembled from cookie data. The only place a visitor's details appear is in a message they send themselves, and those messages are handled the way the Privacy Policy describes. If a message asks about a specific page's cookie behaviour, our reply can name the identifier in use there without touching anyone else's data.

Field note

The address to write to for a policy question is on the contact page.

Two documents sit alongside this one

The Privacy Policy explains what happens to information you send us and how long it is kept. The Terms of Service set out what the reading resource is, and what it is not, before you rely on anything from it.
