Cookie Policy
Last updated: September 2026
This page lists, in plain language, every cookie and browser-storage item OPTOPUS actually sets, and why. It's kept in sync by hand with the codebase rather than generated from a scanner — if something below looks out of date, please let us know.
Strictly necessary — always active
These are required for the site and OPTOPUS AI to function and are never subject to the cookie banner's choice.
| Name | Type | Purpose | Duration |
|---|---|---|---|
| optopus_session | Cookie (HttpOnly, Secure, SameSite=Lax) | Keeps you signed in to your OPTOPUS AI account. Contains only a random session token — never your password or personal data. | 30 days, or until you log out |
| optopus-ai:clientId | Local storage | A random id (no personal data) that identifies this browser to OPTOPUS AI. It is sent with OPTOPUS AI requests, where our server records it and uses it to apply rate limits. Not used for tracking or advertising, and not shared with anyone. | Until browser storage is cleared |
| optopus-lang | Local storage | Remembers whether you last chose English or Spanish. | Until browser storage is cleared |
| optopus:consent | Local storage | Stores the cookie preference you set in the banner/panel on this site. | Until browser storage is cleared |
| optopus-ai:projects optopus-ai:conversations optopus-ai:user |
Local storage | A working copy of your OPTOPUS AI projects and conversations, used only if our server is briefly unreachable. Cleared when you log in, log out or delete your account. | Until browser storage is cleared |
| optopus-wd-explored | Session storage | On the Web Design page, remembers that you already saw the "move to explore" hint so it is not shown again. | Until you close the browser tab |
Analytics & marketing
OPTOPUS does not currently use any analytics, advertising, or marketing tracking cookies or scripts. The preference panel includes Analytics and Marketing toggles so that if this ever changes, your choice is already on record — nothing will be turned on for you without your consent.
Third-party content
A few pages load resources from other services. None of these are analytics or advertising:
- Google Fonts — used on the Marketing and Web Design pages to load typefaces. Loading a font transmits your IP address to Google's servers, standard for any web font CDN; it does not set a cookie.
- jsDelivr — used on the Web Design page to load a 3D graphics library (three.js) for the interactive scene. Same as above: a resource request, no cookie.
- AI provider — OPTOPUS AI's responses are currently generated by Google's Gemini API (unpaid tier); the software can alternatively use the OpenAI API. Your messages are sent from our server (never directly from your browser) to generate a reply, and this sets no cookie in your browser. What is sent is described in our Privacy Policy.
- On the Web Design page, opening "Live preview" for our Experts On House Cleaning case study loads that real client site inside an embedded frame. Any cookies it sets belong to that site, not OPTOPUS, and only load if you choose to open that preview.
Managing your preference
You can change your cookie preference at any time from the "Cookie preferences" link in the footer of any page.
For what OPTOPUS AI stores, what is sent to AI providers, how long data is kept and how to delete it, see our Privacy Policy. Questions or privacy requests: info@optopus.space.
