As the GDPR seeks to protect data users in Europe (and regions where the EU laws apply), it might not really make a difference to data users in India. However, this law extends to both citizens as well as non citizens within the boundaries of the continent. So, if you have plans to travel to Europe, you have the added advantage of being covered by the protections under the GDPR as soon as you land there.
On the other hand, the GDPR requires companies all over the world to comply with its provisions if they provide any goods or services anywhere in Europe, or in any manner monitor the behaviour of any individuals in Europe. This means that some Indian sectors such as information technology, the outsourcing industry and pharmaceuticals might be hit by the GDPR. As the penalty for contravention is up to 4% of the annual turnover of the company, this is not a trivial obligation for affected Indian data controllers.
