( Legal ) — Cookie policy

Only what we need, every cookie named.

Cookies are small files a website asks your browser to keep. RoundAlpha uses a very short list of them, and the list is short on purpose: there is no advertising network here and nothing following you to other sites. The one addition is narrow — if you arrive by clicking one of our own ads, a measurement script reports whether that click led to an account or a plan. This page names every cookie involved.

The short version: we set one cookie of our own — the sign-in token that keeps you logged in — plus a handful of keys in your browser's own storage that never leave your device. We count page views with an analytics tool that uses no cookie and no identifier. Only if you reached us by clicking one of our ads, the ad platform's measurement script adds two more cookies so it can tell us whether that click led to a new account or a plan. Visitors who found us any other way get neither, and one switch further down this page turns both kinds of counting off.

    What this policy covers

    This policy explains the cookies and similar technologies RoundAlpha uses across this website, the practice product and the hiring workspace. Read it alongside our privacy policy, which covers what we do with personal data more broadly.

    “Similar technologies” mostly means your browser's local storage: a place a site can keep small values on your own device. We use it more than we use cookies, because most of what the product needs to remember never has to reach a server at all.

  2. 02

    Cookies we set

    RoundAlpha sets one cookie of its own. It is strictly necessary: without it you would be signed out on every page load, and there is no version of the product that works without it.

    CookiePurposeLifetime
    rtYour sign-in session. Holds a refresh token so the app can renew your access without asking for a new code every few minutes. It is HttpOnly — scripts on the page cannot read it — Secure, and scoped to the sign-in endpoints only.Up to 30 days, or shorter for an invited interview session. Cleared when you sign out.

    That is the complete list of our own cookies. The only other cookies on this site are the ad measurement cookies in the next section, and they are set only for visitors who arrive by clicking one of our ads.

  3. 03

    Ad measurement cookies

    We advertise RoundAlpha on an AI chat platform. When you click one of those ads, the platform adds a reference to the address you land on. Only then — never for a visitor who found us another way — do our public pages load the platform's measurement script, which keeps that reference in a cookie so it can report back whether the click led anywhere.

    It reports three moments and nothing else: a new practice account being created, the payment window opening on a plan, and a plan starting. With the last two it sends the plan and its price. Each report also carries the address of the page it happened on (without anything after the “?”), the page that linked you there, and the two cookie references below.

    It never receives your name, email address, phone number, account, CV, or anything from an interview — not even in scrambled form. It reports nothing from interview, invitation, report or account pages, and a sign-up that starts from a company's interview invitation is never reported.

    CookiePurposeLifetime
    __opprefThe reference the ad platform added to the ad you clicked, so a new account or plan that follows can be credited to that click.30 days
    __obrefA random reference for this browser, created by the measurement script and sent with its reports. It contains no name, email or account id, and it is set on our own domain, so other sites cannot read it.1 year
    __oaiq_domain_probeA test value the script writes and removes straight away, to find out which domain it may set its cookies on.Removed within a minute

    The switch in the Analytics section below turns ad measurement off along with page counting. It stops anything more being sent from this browser; to remove the cookies themselves, clear this site's cookies in your browser.

    Browser storage we use

    These values live in your browser's local storage on your own device. They are not cookies, are never automatically attached to a request, and are not sent to us unless you take an action that needs them — such as starting a session.

    What it holdsWhyLifetime
    Sign-in hintA flag saying you were signed in recently, so a returning visitor is not shown the marketing homepage for a second before being redirected to their dashboard.Until you sign out or clear site data
    Interview setup draftThe CV, role and target company you chose before starting, so a refresh mid-setup does not throw the work away.Until the session starts or you clear site data
    Active call markerA note that a live interview is in progress, so closing the tab by accident lets you rejoin the same session rather than losing it.Until the interview ends
    Recent target companiesThe companies you have typed into setup before, offered back as suggestions.Until you clear site data
    Last interview resultThe report from the session you just finished, so it appears instantly while the full copy loads.Until replaced by the next session
    Audience preferenceWhether you arrived through the candidate or the employer door, so signing in later lands you in the right workspace.Until you clear site data
    Work emailThe work address you entered on the employer door, pre-filled if you come back to it.Until you clear site data
    Practice draftsUnsubmitted system-design diagrams and coding practice work, kept locally so a closed tab does not lose your draft.Until submitted or cleared
    Analytics opt-outSet only if you turn counting off in the Analytics section below, so this browser keeps sending nothing to our page analytics or our ad measurement.Until you turn it back on or clear site data

    Third-party cookies

    We do not embed social widgets, advertising networks or cross-site trackers, so no third party sets a cookie that follows you from RoundAlpha to other sites.

    Four things do involve another party. The first two are things you start; the last two are measurement, each described in full on this page:

    • Google Sign-In — if you choose to sign in with Google, Google's own sign-in page runs under Google's cookies and privacy policy. We receive only your verified name, email address and profile picture.
    • Payment checkout — buying credits hands you to our payment provider's checkout, which sets its own cookies to process the payment and prevent fraud. Your card details are entered there and never on our pages.
    • Website analytics — the measurement script every visitor gets. It is run for us by the company that hosts this website, served from our own domain rather than someone else's, and it sets no cookie at all. The Analytics section below explains exactly what it counts and how to switch it off.
    • Ad measurement — only for visitors who arrive by clicking one of our ads. The script comes from the ad platform, its cookies are set on our own domain, and the “Ad measurement cookies” section above lists every one of them.

    Analytics

    RoundAlpha uses a privacy-preserving analytics tool to count page views. It is run for us by the company that hosts this website, so the script is served from our own domain rather than someone else's. For an ordinary visit it is the only measurement tool here: no advertising pixel, no session recorder, nothing that follows you across the web. Visitors who arrive from one of our ads also get the ad measurement described above.

    It sets no cookie and stores no identifier on your device, which means it cannot recognise you on a later visit or follow you to another site. What it sends is the page you opened, the page that linked you here, and rough details of your device — browser, operating system, screen size and country. That is enough for an approximate visitor count, and not enough to build a profile of you.

    We strip the address before it is sent, so a page whose web address contains an invite link, an interview id or a candidate id is counted as the plain route it came from.

    As well as pages opened, we count a short list of actions: a sign-in button clicked, a CV added, an interview started or finished, a pack bought, an invitation opened. Each one is recorded as a running total with at most two plain details attached — which sign-in method, how many minutes the interview was set to, which pack — and never with your name, your account or anything tying the action back to you. The dashboard can say how many people started an interview yesterday; it can never say who, and it cannot follow one person from one action to the next.

    Nothing you type, say, upload or are scored on is ever part of it. No CV text, no transcript, no report, no written feedback, no company you named — the numbers here are about pages and actions, not people.

    Alongside this we still keep our own server logs — which pages were served, when an interview started and ended, whether a call reconnected — for reliability and security rather than for profiling.

    If you would rather not be counted, use the switch below. It turns off page counting and ad measurement together, takes effect immediately in this browser and needs no account.

    Count my visits

    Off means this browser sends nothing to our page analytics and nothing to our ad measurement. The choice is stored on this device, so it applies to this browser only and is lost if you clear site data.

    Do Not Track and Global Privacy Control

    There is no industry-wide agreement on how sites should respond to a browser's “Do Not Track” signal, so we do not act on it specifically. In practice it makes no difference here: we do not do the cross-site tracking those signals exist to prevent.

    How to control cookies and storage

    You are always in charge of what your browser keeps. Every major browser lets you view, block or delete cookies and clear a site's local storage from its settings, usually under privacy or site permissions.

    Signing out of RoundAlpha clears the session cookie. Clearing site data for this domain removes everything in the tables above, including the local drafts.

    Blocking the session cookie will sign you out and stop the product from working — you will not be able to start or rejoin an interview. That is expected, not a bug.

    Changes to this policy

    If we start using a cookie or storage key that is not listed here, we will add it to the tables above and update the “last updated” date before the change goes live.
