:\ARCHITECT\™
Privacy policy
The Infinitum Corporation. Last updated 12 November 2026.
This page covers the :\ARCHITECT\ web app at rchtch.app and the :\ARCHITECT\ Chrome extension.
The web app
Signing in
You sign in with Cumulus ID at id.cumuluscloud.app. The web app keeps the sign-in token in this tab's session storage, which the browser clears when the tab closes, and sends it with each request so the server knows it is you.
What you send
The tasks you type, the images and files you attach, your comments, approvals and run options go to the :\ARCHITECT\ server, which runs them with an AI model and keeps a record of each run (the plan, the steps, the results and the cost) so you can open it again. @search questions go to VEIL Search, Infinitum's own search engine.
Plans and payments
If you choose a paid plan, your billing email goes to the Infinitum billing service and card details go straight to Stripe Checkout. The web app never sees your card. This browser keeps your billing account key and plan in local storage.
Analytics
We use Amplitude to count page views and sessions, so we know how many people use the app. It does not record what you type, your clicks on forms, your screen or your IP address, and it sends nothing to advertisers. Amplitude stores a random device ID in this browser.
What we do not do
No advertising, no session recording, no selling or renting your data.
The Chrome extension
What the extension sends
The extension talks only to the :\ARCHITECT\ server at rchtch.app, and only when you act in its side panel:
- the goal you type, the autonomy level you choose and the optional start URL, when you press Start run;
- a request to list your recent runs, read one, or cancel one;
- your approve or decline decision on a waiting step, with any note you type.
Requests carry your :\ARCHITECT\ API token and your Cloudflare Access sign-in cookie for rchtch.app, so the server knows they come from you.
The right-click menu Send selection / Send this page copies the selected text, or the page's address and title, into the side panel as a draft goal. Nothing is sent until you press Start run. The extension does not read the text of the pages you visit.
What it stores on your device
- Your API token, in Chrome's local extension storage, until you clear it in Options or remove the extension.
- The unsent draft goal, in session storage, which Chrome clears when the browser closes.
Copy from open Architect tab in Options reads the token that :\ARCHITECT\ saved in an open rchtch.app tab, only when you press that button.
What it does not do
No analytics, no advertising, no tracking, no browsing history, no remote code. We do not sell your data or share it with anyone other than the :\ARCHITECT\ server you send it to. Data handling follows the Chrome Web Store User Data Policy, including its Limited Use requirements.
