01 What cookies are
A cookie is a small text file stored by your browser when you visit a website. Cookies serve many purposes — keeping you logged in, remembering preferences, measuring how the site is used, and (on most sites, though not on ours) tracking you across the web for advertising.
This Cookie Policy explains the cookies we set on edma.trade, app.edma.trade, and related domains, and gives you the information you need to consent or refuse, as appropriate.
02 Cookies we use
We use the following categories of cookies.
Strictly necessary — always on
These cookies are essential for the site to function. They cannot be switched off in our systems. They do not store any information that personally identifies you.
| Cookie | Purpose | Duration |
|---|---|---|
| edma_session | Authenticated session token. Identifies your logged-in session. | Session |
| edma_csrf | Cross-site request forgery protection. Prevents unauthorised actions on your behalf. | Session |
| edma_consent | Records your cookie-consent choice for non-essential categories. | 12 months |
Functional — opt-in
These cookies remember non-essential preferences such as your preferred language, region, or theme. We do not currently set functional cookies; if we add any in future, they will be listed here and require your consent.
Analytics — opt-in
We use Google Analytics 4, loaded through Google Tag Manager, to understand which pages are useful and where the site has problems. It loads only after you accept, and sets first-party _ga and _ga_* cookies that expire after about two years. We do not store your full IP address.
Marketing — opt-in
We use <strong>Google Tag Manager</strong> to manage measurement and advertising tags. Where we run advertising or conversion tags (for example Google or LinkedIn), they set cookies only after you accept marketing cookies. If you decline, they are never loaded.
03 Third-party cookies
We try to minimise third-party cookies. The third-party domains we currently load on our marketing site or in-app, and the cookies they may set, are:
- Stripe — on payment and checkout pages only, to securely process payments. Stripe Cookie Policy →
- Cloudflare — sets a __cf_bm cookie for bot management on protected endpoints. Strictly necessary; cannot be disabled without breaking access.
- YouTube / Vimeo — only loaded if you click an embedded video on our marketing pages; that triggers the relevant provider's cookies for video playback.
We do not embed social media widgets, third-party chat widgets, or advertising trackers.
04 Local storage & similar
The TradeOS application uses browser local storage and IndexedDB for purposes that overlap with cookies: caching reference data so the app loads faster, remembering your sidebar state, and storing draft form inputs locally so you don't lose work on refresh. These are not cookies but are similar technologies under European e-Privacy regulations.
You can clear local storage and IndexedDB through your browser's site-data settings. Doing so will log you out and reset application preferences.
05 How to manage cookies
You have three layers of control.
- Our consent banner — on your first visit you can accept or decline non-essential cookies. You can change or withdraw your choice any time via the Cookie settings link in the site footer.
- Your browser — modern browsers let you block or delete cookies by site, by category, or globally. Browser support pages: Chrome · Firefox · Safari · Edge.
- Privacy extensions — extensions such as uBlock Origin or Privacy Badger work with our site without breaking functionality.
If you reject non-essential cookies, the site and product still work. Some convenience features (e.g. remembered preferences) may be disabled.
06 Do Not Track signals
We honour the Global Privacy Control (GPC) signal as a valid opt-out where your jurisdiction recognises it (including California under CCPA/CPRA). When we detect a GPC signal, we treat it as a request to opt out of any non-essential processing that would otherwise rely on consent.
We do not respond to legacy DNT headers because the specification is no longer maintained, but we apply the same minimisation principles regardless.
07 Changes
If we add or remove cookies, we update this page and reset the consent banner so you can review the new categories. The “Last updated” date at the top reflects the most recent change.
