Cookie Policy
Effective from: 2026-11-02
Last updated: 2026-11-02
This Cookie Policy explains what cookies are, which cookies we use on the mackro.co.uk website and the coach dashboard at coach.mackro.co.uk, and how you can control them. It supplements our Privacy Policy.
This Cookie Policy applies to mackro.co.uk and coach.mackro.co.uk. The Mackro mobile app does not use cookies — it stores an authentication token securely on your device.
What cookies are
Cookies are small text files that a website places on your device when you visit it. They let the site remember things about your visit — such as whether you're logged in, what your preferences are, and what pages you've looked at.
Cookies are either:
- First-party (set by the site you're visiting) or third-party (set by another domain, often through embedded content)
- Session cookies (deleted when you close the browser) or persistent cookies (stored until they expire or you delete them)
- Essential (the site can't function without them) or non-essential (used for analytics, personalisation, or advertising)
Under UK law (specifically the Privacy and Electronic Communications Regulations 2003, as amended), we must ask for your consent before setting non-essential cookies. We do this with a cookie banner the first time you visit the site.
What cookies we use
We use two categories of cookies. We do not use advertising cookies, behavioural targeting cookies, or any cross-site tracking. We do not embed third-party content (Facebook pixels, Google Ads tags, etc.) that would set tracking cookies on your device.
Essential cookies and storage
These are required for the sites to function. They do not require your consent.
mackro.co.uk
| Name | Purpose | Set by | Duration |
|---|---|---|---|
Namemackro_cookie_consent | PurposeStores your cookie preferences (accept all / essential only) so we don't ask again on every visit. Technically a browser local-storage entry rather than a cookie. | Set byMackro | DurationUntil you clear your browser storage |
Coach dashboard (coach.mackro.co.uk) — only once a coach signs in
| Name | Purpose | Set by | Duration |
|---|---|---|---|
Namemk_at | PurposeKeeps you signed in (your access token). Not readable by page scripts. | Set byMackro | Duration30 days |
Namemk_rt | PurposeRenews your sign-in when the access token expires. Not readable by page scripts. | Set byMackro | Duration30 days |
Namemk_mfa | PurposeHolds the two-factor step of signing in. Not readable by page scripts. | Set byMackro | Duration5 minutes |
Namemk_who | PurposeYour name, email and account type, so the dashboard can show who is signed in before it loads. Not a credential. | Set byMackro | Duration30 days |
Namemk-theme, mk-weight-unit | PurposeYour light/dark and weight-unit choices. Browser local-storage entries rather than cookies. | Set byMackro | DurationUntil you clear your browser storage |
All of these stay set whatever you choose about analytics. The dashboard cannot work without them, and signing out clears the cookies.
Analytics cookies (consent required)
We use PostHog to understand how the marketing site is used — which pages get traffic, where visitors come from, and where the conversion funnel breaks down. On mackro.co.uk, PostHog only loads once you accept analytics cookies. The coach dashboard uses PostHog without cookies or browser storage.
| Name | Purpose | Set by | Duration |
|---|---|---|---|
Nameph_*_posthog | PurposeStores an anonymous device ID to deduplicate visits and follow conversion funnels. Set as a cookie and as a browser local-storage entry of the same name. PostHog also keeps two session-storage entries (ph_*_window_id, ph_*_primary_window_exists) to tell your browser tabs apart | Set byPostHog (first-party setup) | DurationCookie: 12 months. Local storage: until you clear your browser storage. Session storage: until you close the tab |
Namemackro_attrib | PurposeRemembers the campaign tags (utm_*) on the link you arrived from, so the rest of your visit is credited to that link. A browser session-storage entry rather than a cookie | Set byMackro | DurationUntil you close the tab |
If you decline analytics cookies, we don't set any of these. We may still see anonymous server-side request counts (which don't use cookies) for capacity planning.
We do not use Google Analytics. We do not use Meta Pixel. We do not use any cross-site advertising or retargeting tags.
How to control cookies
You can manage cookies in three ways:
1. The cookie banner. When you first visit mackro.co.uk we show a banner asking whether you accept analytics cookies. You can also reopen the preference panel any time by clicking "Cookie preferences" in the website footer.
2. Your browser settings. All major browsers let you block or delete cookies. The exact steps differ by browser — search "manage cookies in [your browser name]" for instructions. Note that blocking essential cookies means you won't be able to sign in to the coach dashboard.
3. Per-cookie opt-out. Some third parties offer dedicated opt-out mechanisms. PostHog respects the Do Not Track browser signal — if you have DNT enabled in your browser, we won't load the PostHog cookie regardless of your banner choice.
What happens if you decline non-essential cookies
The website works exactly the same. You can read all the content, join the launch mailing list, and access the privacy policy and terms.
The only thing that changes is that we don't get analytics data from your visit. This means we get a less complete picture of how the marketing site is performing, but it does not affect your experience.
Changes to this Cookie Policy
If we add a new cookie or change how an existing one works, we will update this policy and re-prompt you for consent if the change affects non-essential cookies. The "Last updated" date at the top reflects the most recent change.
The latest version is always available at mackro.co.uk/cookies.
