J'ai posé la question au BizDev Manager concernant la légalité de leur données et voici l'échange:
I am very impressive by your solution. But, In our company, we only use software that are totally legal. And, as I noticed, some mobile phones are not public, so I wonder where did you get it. If you can garantee that the way you find them are 100% legal, I'm interested.
Thanks for your email Hamadi
Our data providers are all have legal access to those contact details.
If it will help you fill better, Google & Microsoft are a paying customers.
** I've no doubt that your data providers have legal access to those contact details BUT do they have legal authorization to give those data to third party (Lusha) ?**
If the service was not legal we will not provide it to the public
Many thanks for your feedback
