Safe on the ground events

Maybe the question should be about the legitimate interests to ensure the constant safety throughout the events.
(Le traîtement des données pour organiser la gestion des événements se trouve au base de nos intérêts légitimes d'assurer la sécurité perpetuelle des événements.)

En complément de ce qui a déja été évoqué,

Par exemple à titre indicatif (dans le cadre du traitement de données de la billetterie d'une célèbre marque) (révision 07/23)

Yes, there many types of "ground event" but in this ST you need a "ticket contract" so only some of them would be relevant.

This is obviously a fragment of some "privacy policy" of some company selling or only processing "ticket contract" (clue: mention of "legitimate interest" to keep some data), but without knowing for sure what's the business of this company, we can only keep guessing.

safe on the ground events
=
on the ground events = events happening on a physical locality (="the ground") with participants physically present (as opposed to "virtual meetings" like a teleconference or similar)

safe = make sure these "on the ground events", are "safe" (whatever is exactly the organisers' idea of "safety", better not start a long digression).

When it comes to selling tickets, "safety" in this text would in practice mean refusing to sell tickets to some categories of would-be buyers, for whatever reason.

Instead on dwelling on the best translation for "safe/safety", I would be tempted to use a workaround, like "en vue d'assurer le bon déroulement des événements".
