Happy Data Privacy Day! Yes, it’s a completely made-up holiday, but it’s as good a time as any to take a hard look at your online life and shore up your efforts to protect your personal digital privacy.

The annual occasion, feted by cybersecurity and digital privacy enthusiasts around the world, began in the US and Canada back in 2008. It’s an extension of a European commemoration marking 1981’s Convention 108, the first legally binding international treaty on protecting privacy and data.
