ХХХ is the data controller responsible for the Business Conduct Hotline. Any personal information you share with us may be used to address or investigate the reported issue or situation ***that you allege may be inappropriate***. This Business Conduct Hotline is optional and its scope may vary by country.

ХХХ – это оператор данных, который отвечает за Горячую линию по ведению бизнеса. Любая предоставленная Вами личная информация может быть использована для рассмотрения или расследования проблемы или ситуации, ***которую Вы можете посчитать неправомерной***. Горячая линия по ведению бизнеса является факультативной (необязательной для применения?) и в разных странах может охватывать различные сферы деятельности.

'To allege' (as well as 'alleged' and 'allegation') is an important word in UK legal English which indicates that Person A (an individual/the police/an organisation) says that Person B has done something wrong, but that the relevant official person or body (eg an arbitrator, an ombudsman, a regulator, a court, a tribunal or a similar body) hasn't yet decided a) whether or not an offence has taken place, and/or b) whether or not the person/organisation accused of the offence, is guilty of it.

So it's a 'safeguard' word used to protect those who have been accused of sth, until an official person/body has decided whether or not they're guilty of it.
