Cookie policy
How Stratumly uses cookies and similar storage on this site, the vendors involved, and how to manage your preferences.
Last updated: 2 May 2026
What this policy covers
This policy explains how stratumly.com (the marketing site) and stratumly.com/docs (the documentation site) use cookies and similar storage technologies (HTML5 localStorage) when you visit. It also lists the third parties that set or receive data through these technologies.
Use of the Stratumly product itself (in-app cookies, session tokens, and platform telemetry) is governed by your Master Subscription Agreement and the associated Data Processing Agreement, available on request. That contract takes precedence over this page for any in-product activity.
How consent works
When you first visit the site you see a banner with three choices: Accept all, Reject all, or Customise. Strictly necessary cookies are set regardless. Every other category requires your explicit opt-in before the corresponding scripts load. Your choice is stored in your browser for 12 months, after which we re-prompt.
You can change your mind at any time using the link in the site footer.
Cookies and storage we use
Strictly necessary
Required for the site to load, render correctly, remember your cookie choices, and apply security headers. These cannot be disabled.
| Vendor | Name / scope | Purpose | Storage | Party | Retention |
|---|---|---|---|---|---|
| Stratumly | stratumly_consent_v1 | Stores your cookie preferences (which categories you allowed) so the banner does not re-prompt on every page. | localStorage | First-party | 12 months |
| Stratumly | Theme preference | Remembers whether you chose light or dark theme so the site renders consistently between visits. | localStorage | First-party | 12 months |
Analytics
Help us understand which pages are useful, which need work, and which break. Loaded only after you opt in. Two of the three vendors here are cookieless and aggregate-only.
| Vendor | Name / scope | Purpose | Storage | Party | Retention |
|---|---|---|---|---|---|
| PostHog (EU region) | ph_*, __ph_opt_in_out | Anonymous page views, button clicks, and product analytics. Hosted in the EU for UK data residency. | cookie | Third-party | 12 months |
| Vercel Web Analytics | (none) | Cookieless page-view counts and traffic sources. No persistent identifier; no cross-site tracking. | request | First-party | Per request only; aggregate retained 30 days |
| Vercel Speed Insights | (none) | Cookieless Core Web Vitals (page load timings) so we can spot performance regressions. | request | First-party | Per request only; aggregate retained 30 days |
Marketing
Used to attribute traffic to campaigns, measure advert effectiveness, and target relevant content on other sites. Loaded only after you opt in.
| Vendor | Name / scope | Purpose | Storage | Party | Retention |
|---|---|---|---|---|---|
| Google Tag Manager / GA4 | _ga, _gid, _gtag_*, _dc_gtm_* | Routes events from the site to downstream marketing tags (when configured). GA4 records page views and custom events with anonymised IPs. | cookie | Third-party | Up to 2 years (GA4 default 14 months, configurable) |
| Meta, LinkedIn, etc. (when configured) | Downstream pixel cookies | Attribution and retargeting. Only loaded if a corresponding tag is enabled in our GTM container. | cookie | Third-party | Vendor-specific, typically 90 days to 13 months |
Preferences
Reserved for future non-essential UI choices. Currently unused.
No cookies in this category at present.
Browser-level controls
Beyond the in-site preference centre, you can clear or block cookies at the browser level. The exact steps depend on your browser:
Stratumly also respects the browser Do Not Track (DNT) signal: if your browser sends it, we will not load PostHog regardless of your banner choice.
Changes to this policy
When we add or remove a vendor, we update the table above and bump the "Last updated" date. Material changes (a new vendor category, a change in legal basis) will trigger a new consent prompt on your next visit.
