A temporary Session ID may require consent if it is stored as a cookie. However, regulators such as CNIL (France) and AEPD (Spain) have clarified that consent is not required if the Session ID meets certain strict conditions:
It is used exclusively for audience measurement.
It does not track users across different sites.
It does not persist beyond the browsing session.
It cannot be combined with other identifiers to re-identify the user.
Sealmetrics offers two options:
Session ID mode → Temporary Session IDs, compliant with CNIL/AEPD guidelines.
Super-Privacy mode (Isolated Hits) → No Session ID at all.
