There are two different situations, and they behave differently:
A person invited directly into this round(clause 01's normal path) can ask, at any point, to have everything we hold about them deleted — we do it on request, no conditions. What doesn't exist yet is a lighter-weight option: withdrawing just this round's answers while keeping the account for future use. Today it's all-or-nothing.
A person who took a personal, standalone assessment earlier and separately chose to link that existing result into your organisation's aggregate did so through an explicit, revocable consent, scoped to that link alone. They can withdraw it at any time without touching their account; withdrawing stops it contributing to future recalculations.
Neither path rewrites a report already published from an earlier calculation — we say this plainly rather than implying full erasure reaches issued results.
Only “delete everything,” not “just withdraw from this round”
If your works council expects an employee to be able to pull their answers out of a live round while staying enrolled in the platform, that specific, lighter option doesn't exist yet — only full deletion does. Worth raising with us before fielding if your organisation needs the lighter version.
