We use very few cookies, and none for advertising or analytics. This page lists each one. It covers our own websites, the app, and the cookies our platform sets on pages our customers publish.
Cookies are small text files a site stores in your browser so it can remember something between page loads. Browser storage (local storage) does a similar job. This policy covers both.
On our own websites, the only cookies that are not strictly necessary are the two partner referral cookies listed below. They are set when you arrive through a partner's link, without a cookie banner first, and hold only the partner's code and campaign tag. You can delete them at any time, or block cookies for opusfunnel.com, in your browser settings. Strictly necessary cookies and storage, the ones a feature you asked for cannot work without, do not need consent.
On pages our customers publish, the platform asks the visitor before it sets a referral cookie. See On pages our customers publish.
| Name | Purpose | Lasts | Type |
|---|---|---|---|
of_pref | Remembers the partner whose link brought you here, so they can be credited if you sign up. Set on every opusfunnel.com site when you follow a partner's link | The partner program's window, currently 90 days | Functional: not strictly necessary |
of_psub | The campaign tag on that partner's link | Same as of_pref | Functional: not strictly necessary |
of_aff | Keeps a partner signed in to the partner portal | 30 days | Strictly necessary |
__cf_bm and similar | If Cloudflare's bot protection is active, it may set a cookie to tell people from bots | Up to 30 minutes | Strictly necessary |
If you block or delete these cookies, a partner who sent you may not be credited for your sign-up. Nothing else changes.
Our websites set no analytics, advertising or social media cookies.
| Name | Purpose | Lasts | Type |
|---|---|---|---|
| Sign-in session (local storage) | Keeps you signed in | Until you sign out | Strictly necessary |
| Preferences (local storage) | Remembers choices you make, such as light or dark theme, recently opened accounts and the client account you are working in | Until you clear them | Strictly necessary |
| Drafts and retries (session storage) | Keeps an unsaved draft or a pending payment step while the tab is open | Until you close the tab | Strictly necessary |
Sites, funnels, stores and member areas published with OpusFunnel belong to our customers, who are responsible for telling their visitors about cookies and getting consent where the law requires. So they can do that, here is what our platform sets on those pages:
| Name | Purpose | Lasts | Type |
|---|---|---|---|
of_buyer | Keeps a buyer or student signed in to their account area | 30 days | Strictly necessary |
ofc_… | Holds the shopping basket | 30 days | Strictly necessary |
ofq_… | Holds survey or quiz answers between steps | 2 hours | Strictly necessary |
ofw_… | Remembers that the welcome offer box was shown, so it is not shown again | 1 year | Functional |
of_aff | Keeps a partner signed in to the business's partner portal | 30 days | Strictly necessary |
of_ref, of_sub | Remember the partner and campaign that referred the visitor, when the business runs an affiliate program. Set only after the visitor presses "Accept" on the bar the page shows, which has "No thanks" beside it. Until then, and after "No thanks", nothing is stored: the referral is carried in the page's own links instead | The program's window, set by the business (1 to 365 days) | Non-essential: set only with the visitor's consent |
of_ok | Remembers that the visitor accepted the referral cookie, so the bar is not shown again | Same as of_ref | Strictly necessary |
YouTube videos are embedded from youtube-nocookie.com, and Vimeo videos with Vimeo's "do not track" option, so that those services do not set cookies before the visitor plays the video. Once a video is played, the service may set its own cookies under its own policy. Published pages do not run third-party tracking scripts.
Marketing emails sent through OpusFunnel can record when an email is opened (using a tiny image) and when a link is clicked. This works like a cookie and may need consent. Each business controls it with a setting: it is off by default for a business based in the EU, the EEA or the UK, and on by default elsewhere. Where a business keeps it on, it must have any consent the law requires. Transactional emails such as receipts are not tracked.
Every browser lets you block or delete cookies and site data. If you block strictly necessary cookies and storage, you will not be able to stay signed in.
Version history: 2026-09-24, rewritten to list every cookie, describe how referral cookies are set and cover customers' pages and email tracking. 2026-08-20, previous version.
