This page describes exactly which cookies and local storage mechanisms are used by Sentinel on sentinelbriefing.com. We have deliberately chosen to use no marketing or advertising cookies.
A cookie is a small text file placed on your device by a website. Cookies allow information to be remembered between visits (session, preferences, etc.). Sentinel also uses the browser's localStorage — a similar mechanism that is never sent to the server and stays entirely local on your device.
| Name | Type | Category | Duration | Purpose |
|---|---|---|---|---|
sentinel_session |
HTTP cookie (server) | Essential | 24 hours | Maintains the authentication session. Without this cookie, it is not possible to stay logged in. |
sentinel_lang |
localStorage | Essential | Persistent (until cleared) | Remembers your language preference (FR/EN) so you don't need to set it on each visit. |
sentinel_theme |
localStorage | Comfort | Persistent (until cleared) | Remembers your chosen visual theme (light or dark) to personalise the display. |
py_consent |
Cookie (browser) | Essential | 6 months | Keeps your audience measurement choice ("accepted" or "refused") so that you are not asked again on every page. |
| Audience measurement without an account (Umami, self-hosted in the EU) | No cookie or storage | Analytics | Not applicable | Always, unless Do Not Track or Global Privacy Control is on: page views (without the address parameters), referrer, device type and a few steps, counted without being linked to a person or an account (visit identifier computed by Umami with a salt renewed every month). Exempt from consent, deleted after 25 months. Details. |
ph_<key>_posthog |
Cookie and "ph_…" localStorage | Analytics | 6 months, only after acceptance | Only after "Accept" (without consent, PostHog is not loaded): journey followed on this site only, linked to your account by its internal identifier (never your email or name) and to your organisation, sessions recorded (deleted after 30 days) with inputs and text masked. Deleted if you decline later. |
Sentinel uses none of the following:
Audience measurement: Manage cookies (reopens the banner; declining deletes the ph_… cookies).
Essential cookies are required for the Service to function and cannot be disabled. localStorage data (theme, language) can be cleared at any time via your browser's developer tools (F12 → Application → Local Storage).
You can also disable cookies in your browser settings. Note that disabling the session cookie will automatically log you out.
