Cookie Statement
Last updated: [pending — effective date] · Version 1.0
What are cookies?
Cookies are small text files a website places on your device. They let the site remember things like whether you're signed in, what preferences you've chosen, and how you reached the page. Some cookies are essential for the site to work; others are optional.
How we use cookies
HemeraScope uses cookies in three narrow, essential ways: to keep you signed in, to remember a small number of UI preferences, and to protect the site against common web attacks. We do not currently run advertising or cross-site tracking cookies.
Under the Privacy and Electronic Communications Regulations 2003 (PECR), as updated by the Data (Use and Access) Act 2025 which came into force on 5 February 2026, we must ask for your consent before setting any cookie that is not strictly necessary. For strictly necessary cookies we can rely on the “strictly necessary” exemption and do not need consent; we list them transparently below so you can see what they do.
Cookies we set
| Name | Set by | Purpose | Duration | Category |
|---|---|---|---|---|
| __session | Clerk | Keeps you signed in to HemeraScope. | Session / rotating | Strictly necessary |
| __client_uat | Clerk | Tracks the latest authentication timestamp to detect concurrent sessions. | Session | Strictly necessary |
| __clerk_db_jwt | Clerk | Stores the signed session token. | Session / rotating | Strictly necessary |
| csrf_token | HemeraScope | Protects against cross-site request forgery on form submissions. | Session | Strictly necessary |
| hemera_consent | HemeraScope | Remembers your cookie preferences so we don't ask again on every visit. | 12 months | Strictly necessary (consent record) |
If we add any analytics, product-intelligence, or marketing cookies in future, they will appear in this table and will require your opt-in consent before being set.
Managing your preferences
You can change or withdraw your consent at any time via the “Cookie settings” link in the footer. You can also control cookies through your browser settings — every major browser lets you block or delete cookies on a site-by-site basis.
Blocking the cookies listed as “strictly necessary” will prevent HemeraScope from working — you won't be able to stay signed in or submit forms.
