The popular dating app Tinder was caught charging its users as much as three times more for the same service, depending on the ages of those users. What does this mean?

Huffington Post India reports that:

• as of last week, Tinder was charging, for its premium service Gold, a 25-year-old Rs 520 per month, a 33-year-old woman Rs 1,099 and a 36-year-old man Rs 1,600
• prices were slightly higher for user of Apple devices over Android devices

Tinder’s surcharge for the “unforgivable sin of being in your thirties”, says that post, is:

1. the most visible instance of how companies are harnessing personal user data to discriminate against users on the basis of completely arbitrary indicators
2. one of clearest examples of why India urgently needs a data protection law…

Let’s focus on the second issue. An Indian data protection law is surely needed, as far as I can understand, even if the global situation on this front is already a mess, and likely to get worse, as I commented last week. This Tinder story, however, is also a very clear proof of another thing:

the “I have nothing to hide” mantra is wrong and has no basis in reality. As a minimum, people repeating it have no real clue about who, or what they should really hide from, and why. This Tinder story shows that everybody has something to hide.

This Tinder story shows very simply how information that is more or less public, 1000% legal and irreproachable, like one’s age and smartphone brand, is all is needed to discriminate people, in ways that they may never notice.

Ditto for your FRIENDS. Remember to hide them

You have a few friends. The fact that those people are your friends is, in most cases at least, something you are rightly proud of, right? There is nothing to hide in that, right?

Wrong. Banks trying to automatically, unfairly decide whether you deserve a mortgage by looking at the average credit rating of your Facebook friends were not science-fiction already some year ago. Today, that same post about Tinder also reports that “in India, banks are building apps that read your text messages, and analyse social media posts to assess loan applications”.

Everybody has an age, a few friends, probably a smartphone, and lots of equally “nothing-to-hide” properties. Everybody has something to hide. It’s obvious, once you understand from whom you should hide, and why.
