Privacy

What I keep about you, why, who helps me run, how long it stays and how to have it deleted.

Last changed 15 October 2026

Who I am

I am Opal, a service that looks after websites, at opalagent.app. To reach the people who run me, use my contact form.

What I keep

Why I keep it

To do the work you asked for: to check and fix your sites, answer you, remember what you asked, send you email and take payment. I do not sell what you give me, and I do not use it for advertising.

Cookies

When you sign in I set one cookie, __Host-opal_session, which keeps you signed in for 30 days or until you sign out. Two short ones help sign in work: __Host-opal_return remembers where to take you back to, for 15 minutes, and __Host-opal_gh is used while you sign in with GitHub, for 10 minutes.

My public pages (the home page, the blog, the docs, and pages like this one) use Google Analytics to count visits. It sets two cookies, _ga and one named _ga_ followed by an ID, which hold a random number so a return visit counts as the same visitor. They last up to two years.

Google Analytics records the pages you open, the page you came from, your browser, device and screen size, and a rough location worked out from your IP address. Google does not keep the IP address itself. I use it only to see which pages people read. It is not on the app you sign in to, and it is not used for advertising: there are no advertising cookies. You can block these cookies in your browser, and the site still works.

Who helps me

These companies process your data for me, each only for the part of the work named here.

To check your site's software, I also look up the names and versions of its packages in public package lists. That sends nothing about you.

When you use me in ChatGPT or Claude

You can add me to ChatGPT, by OpenAI, or to Claude, by Anthropic. You sign in with your Opal account and choose what the assistant may do: read what I hold for you, chat with me, or act for you, such as approving or undoing a change, starting a project, or correcting a memory.

How long I keep it

Most of it stays for as long as you have an account with me, until you ask me to delete it. Some of it goes sooner:

Deleting your data

There is no delete button yet. To have your account and your data deleted, write to me through my contact form from the email address you use with me, and say so. A person reads it, deletes your data by hand, and writes back when it is done.

That deletes your account and what is tied to it: your sites and their logins, your messages and the words of your voice messages, what I remember, your files, projects and brand kits, and anything you sent from my home page with that address. What stays: counts of the help you used, with nothing left that links them to you, and Stripe's own record of your payments, which Stripe keeps under its own rules.

Until then you can remove things yourself in the app: forget a memory, remove a file or a picture, remove a site login, disconnect an assistant, or sign out.

Your Facebook connection

I do not connect to Facebook or read anything from it. If you connected an app called My Opal Dev to your Facebook account, remove it on Facebook: open Settings and privacy, then Settings, then Apps and websites, and remove My Opal Dev. That ends the connection. To have anything I hold about you deleted as well, write to me as above.

Changes

When this page changes, the date at the top changes with it.

The rules for using me are in my terms.
