1. What a cookie is
A cookie is a small text file your browser stores on your device when you visit a site. Some cookies are essential — the one that keeps your session alive, for example. Others measure visitor behaviour or serve advertising; those require consent.
Browsers also offer a similar area called local storage (localStorage, sessionStorage). That area is never sent to the server and stays only in your browser; this policy covers it too.
2. On this corporate site (prefux.com)
The site you are reading sets no tracking or advertising cookies. It keeps only two technical records in your browser, neither of which is ever sent to the server:
prefux-theme(local storage) |
Remembers your choice when you switch the light or dark theme manually. It stays in your browser only, is never sent to the server, and is not linked to your identity. If you delete it, the site falls back to your device's system preference. Duration: until you delete it. |
|---|---|
prefux_site_config_v1(session storage) |
A one-hour temporary cache so the site does not re-request its configuration on every page load. It contains no personal data and is deleted when you close the tab. |
Both records are necessary for the service to work and carry no tracking purpose, so they do not require consent. That is why you do not see a cookie banner here: right now there is no tracking cookie to consent to. If measurement is enabled (section 5), this page is updated and consent management is put in place.
3. In the web panel (app.prefux.com)
The panel uses only one strictly necessary cookie:
| Session refresh cookie | Keeps your session open. It is flagged HttpOnly and Secure, meaning no script on the page can read it and it is only sent over an encrypted connection. It is not used for tracking or profiling. Without this cookie you cannot sign in, so it does not require consent.Duration: 30 days — or the moment you sign out or revoke the session. |
|---|
The panel may also keep interface settings such as your theme preference in your device's local storage. These are not sent to the server.
4. In the mobile app
The mobile app uses no cookies. The key that keeps your session alive is stored in the secure store protected by the device's operating system (iOS Keychain / Android Keystore). The access key is held in memory only and is lost when the app closes. Both are deleted when you sign out.
The app contains no advertising network or tracking SDK and does not read your advertising identifier (IDFA / Android Advertising ID).
5. Measurement and analytics
On this corporate site, measurement (Google Analytics 4) loads only when a measurement ID is configured from the administration panel. If no ID is configured, no analytics script is downloaded and no measurement cookie is set.
As of 7 August 2026, the date this text was published, measurement is not enabled. If we enable it, we will update this section to state which cookies are set and how you manage your consent.
When measurement is enabled, the IP address is anonymised before being sent. Sharing data with advertising networks, remarketing and user-level profiling are never performed under any circumstances.
6. How to manage cookies
You can view, delete or block cookies and local storage from your browser's settings. In most browsers the relevant section is under Settings → Privacy and security → Cookies and site data.
- Deleting the records on this corporate site only resets your theme preference; the site keeps working normally.
- If you block the panel's session cookie, you will not be able to sign in — that cookie is essential for the service to function.
- In the mobile app, signing out is enough to end your session.
7. Changes to this policy
If the cookies we use change, we update this page. Before we start using any cookie that requires consent, we put consent management in place so that your consent is obtained before such a cookie is set; today we use no such cookie, which is why there is no consent banner. The date at the top of this page always reflects the version in force.
