GreaseDroid is my latest project. It aims to give end-users more choice about the technology they rely on.

The idea is to create a community of patch developers that write instructions that describe how to modify certain app features. In turn, end-users — even those with limited expertise — can choose what modifications they would like to make to their apps.

At the moment, GreaseDroid allows users to block apps’ access to personal information, as well as remove distracting elements from the Twitter app.

TrackerControl is an Android app to restrict tracking on smartphones. Tracking means collection of data about app usage. This includes the times when you start and close an app, and what buttons you click.

TrackerControl helps you stay safe on every mission.

My colleagues at Oxford found that 90% of apps can share data with Google, and 40% with Facebook.

Pretty scary, but does it surprise you? Give the app a try, if you want to learn if you’re being tracked, too. (Spoiler: Yes)

You’ve probably heard of the EU General Data Protection Regulation (GDPR). But, would you know what it means? Presumably something with data protection, ha?

Just like TrackerControl helps app users, helps app developers.

Software developers have to apply this law to their software. But, the thing is highly complex and ambiguous.

This is why I tried to summarised the essentials of GDPR for app developers. If you’re one of them, check it out!


Ever felt like exploring a different identity? Well, then IdentiSwap might be something for you. If not, why not try?

IdentiSwap is a browser extension that allows you to see what a first-time visitor on YouTube would see for their next-up recommendations. That’s the stuff on the right hand side, when playing a video.

The YouTube next-up recommendations (in red) are really good. You click, and click, and…

It’s been speculated that these recommendations have brought Trump into office because they drive you to ever more extreme, sensational content. Remember videos watched spent means ads served for YouTube. A coincidence?

Again, pretty scary. I really wonder how I manage to keep sane in my PhD. Anyways, give it a try if you’re bold!
