Cookie Policy
Sentrel uses only strictly necessary cookies and browser storage. There is no analytics, no advertising and no third-party tracking anywhere in the product or on this website, which is why you are never asked to dismiss a cookie banner.

1. What we use, and nothing else
Every item below exists so you can stay signed in and see the right interface. Remove them and the product stops working, which is the definition the law uses for "strictly necessary".
| Purpose | Stored as | What it does | How long |
|---|---|---|---|
| Keeping you signed in | Cookie and browser storage | Holds your session so you are not asked to sign in again on every page, and authorises the requests your browser makes to us. Part of it is set by our server and cannot be read by scripts running in the page. | 7 days, or until you sign out |
| Showing you the right interface | Cookie | Records which parts of the product your role is allowed to open, so the correct navigation appears immediately instead of after a delay. Contains no password and no credential. | 7 days |
| Remembering your preferences | Browser storage | Small choices you have already made, such as whether you collapsed the navigation, and a local list of your recent assistant conversations so they do not have to be fetched again. | Until you sign out or clear your browser |
| Supported access to your account | Browser storage | Present only while a member of our support team is working inside your account with authorization, and only for as long as that takes. Every action taken this way is recorded in your audit trail, where you can see it. | Until that support session ends |
These are grouped by what they are for rather than listed as individual technical names. What matters to you, and what the law asks us to tell you, is the purpose and how long it lasts. If you would like the item-by-item detail for a security review, ask us and we will send it.
2. What we do not use
- No analytics of any kind. No Google Analytics, no product analytics, no session recording or heatmaps.
- No advertising or retargeting pixels, and no social media tracking.
- No cross-site tracking and no data brokers.
- No profiling, and no fingerprinting.
This is a statement about the code, not an aspiration. If it ever changes, this page changes first and consent is collected before anything is set.
3. Why there is no consent banner
Under Regulation 6(4) of the UK Privacy and Electronic Communications Regulations, and Article 5(3) of the EU ePrivacy Directive, consent is not required for storage that is strictly necessary to provide a service the user has asked for. Everything we set falls in that category, so there is nothing to consent to.
If we ever introduce anything beyond strictly necessary storage, we will ask first, the choice will be genuine, and refusing will be as easy as accepting.
4. Controlling storage yourself
Every browser lets you view, block and delete cookies and site data through its settings. Signing out clears the session items listed above.
We honor a Global Privacy Control signal if your browser sends one. Since we do not sell or share personal information, it has nothing to switch off here.
