COOKIES AND TECHNICAL TOOLS
Cookie Policy
Last updated: 3 September 2026
1. Current situation
The public Gechi Chan showcase does not use profiling cookies, analytics, advertising pixels or embedded third-party content. Instagram links do not transmit data to the external service until the user opens them.
2. Technical tools in the private area
| Tool | Purpose | Indicative duration |
|---|---|---|
| Session cookie | Authentication, security and maintenance of the Lab session. | Browsing session or until sign-out. |
| “Stay signed in” | Securely restores access on a personal device without storing the password in plain text. | Up to 180 days; removed on sign-out or invalidated after revocation or changes to the password, role or account status. |
| Local storage | Associates the cache with the correct user and stores technical preferences, such as the base URL for QR codes. | Until website data is deleted or the technical value is replaced. |
| IndexedDB | Queues records created offline and not yet synchronised. | Until synchronisation or manual deletion of local data. |
| Cache Storage and service worker | Makes the app and authorised pages available offline. | Until a version update, an account change or deletion of website data. |
3. Consent
These tools are necessary to provide authentication, security and offline features requested by the user. They are not used for profiling or advertising and do not require prior consent. For this reason, the website does not display a cookie banner.
4. How to delete them
Cookies and local data can be deleted in the browser settings. In the private area, “Sign out” revokes the session and persistent access; deleting all website data also removes caches and offline archives that have not yet been synchronised.
5. Future changes
If analytics, embedded content or tools that are not strictly technical are introduced in the future, this notice will be updated and consent will be requested where necessary.
