Where we rely on our legitimate interests, we will always make sure that we balance these interests against your rights.

We will not retain your data for longer than is necessary to fulfil the purpose it is being processed for. To determine the appropriate retention period, we consider the amount, nature and sensitivity of the personal data, the purposes for which we process it and whether we can achieve those purposes through other means.
