THE MOBILE PROTECTION PARADOX Sitting around waiting for a virus or malware to attack your mobile device just doesn’t make sense. But that’s exactly what most security apps do – they wait for a threat to attack before they spring into action, and by then it can be too late. Plus, lots of the same apps that claim to be there to protect you also peep and pry into your personal data! PROTECTION THAT’S PROACTIVE Not us. At Quokka we think keeping your devices and your personal data safe is not a passive exercise – you have to be proactive. And proactive protection definitely shouldn’t mean your privacy is up for grabs. When it comes to mobile device security, we believe personal privacy and mobile security should live in harmony. Enter Q-Scout! Q-Scout’s proactive protection is always-on to keep you steps ahead of threats. It sniffs out security gaps, alerts you to any app that is behaving badly and tells you how to slam the door in bad guys’ faces…all before threats strike. Q-Scout also hunts for the ways hackers attempt to sneak in through your often overlooked access points like your camera or microphone (yes, they try that, too!) And it does it all without ever touching your private data or content. INTELLIGENCE IN ACTION (IT’S AS SMART AS IT SOUNDS) After identifying threats for more than a decade, our database is massive and wicked smart. Q-Scout uses “Actionable Intelligence” to uncover what the apps on your mobile device are secretly up to. Not everything may be a threat, but if it’s out of the ordinary – like an app accessing your camera without a logical reason – we let you know. Q-Scout gives you the power to tell those apps who’s boss. We push updates for every app and every device literally all the time, so you’re covered for every install, every day. Q-Scout also does all of its heavy computational powerlifting in the cloud, so you can keep on listening, scrolling, and getting those followers up without ever feeling a drag on performance. PROTECTION, WITH A LIGHT TOUCH All this protection comes without snooping into your private, personal data. We think your photos, texts, emails, playlists, and anything else uniquely, digitally “you” is always 100% yours. Q-Scout doesn’t need to dig into your beach pics or texts to Uncle Larry to spot security gaps, so we never do. It’s your device and your data – we’re just here to help keep it all safe. Start living your mobile life knowing you’re ready for threats before they even show up. Q-Scout puts you in control and leaves the bad guys out in the cold!

Saying “No” to commercial surveillance is as easy as renaming your device & our app makes it even easier! Invented by Privacy4Cars, OptOutCode is a new Universal Opt-Out Mechanism that only requires to add the prefix 0$S = Do Not (zero) Sell (dollar) or Share (capital letter S) as the first three letters of the name of consumers’ smartphones, computers, and wi-fi router. More info at https://optoutcode.com/ OptOutCode has four distinguishing advantages: 1. It is truly Universal: OptOutCode is compatible with smartphones, laptops, tablets,routers, the apps that run on them and the IoTs they connect to, including vehicles, smart appliances, tracking beacons, and more. 2. It’s fully decentralized: OptOutCode does not require to build, maintain, query, or secure a central database of opting-out users, devices, or apps. The signal is detected locally: either by the programs and apps running on the device that has OptOutCode turned on (e.g., an app on a smartphone), or by other devices that connect to the device of the Consumer that has OptOutCode turned on (e.g. a SmartTV connected to a Wi-Fi router with OptOutCode on, a fitness watch connected to a smartphone with OptOutCode on). This architecture makes it privacy-preserving, more secure, without a single point of failure, cheaper, and faster. 3. It’s Consumer-friendly: All Consumers need to do to turn on OptOutCode is simply rename their devices by adding “0$S” as the first three characters. For instance, rename their phone from “My Phone” to “0$S My Phone”. Most Consumers can do it themselves by going through the settings of their devices in less than a minute, but we have also written code to automate the task of turning OptOutCode on or off with a simple “switch” on an app. 4. It’s business-friendly: Businesses can easily read and parse the “0$S” opt-out code from each device using backward-compatible and future proof protocols that require no special authorizations. We want to thank Professor Sebastian Zimmeck of Wesleyan University (credited with inventing GPC) for recently pointing out to us that Google has a somewhat similar protocol to allow users to opt-out of their Wi-Fi routers’ signals to be used by Google Maps, providing an independent industry validation that a portion of the name of a device can be used as an opt-out signal. This app has three purposes: 1. It makes it even easier for consumers to turn on OptOutCode on their iOS devices 2. It demonstrates how easy it is for companies who make apps (social media, gaming, dating, mapping, etc.) to detect OptOutCode and understand that consumer wants to opt-out of targeted advertising and other privacy-invading AdTech. Similarly, it demonstrates how easy it is for companies who make and/or deploy IoTs that connect to devices with OptOutCode to respect the privacy of those users. 3. It offers companies who want to promote privacy a simple way to integrate the OptOutCode “switch” into their own apps (we also created a banner they can add to their websites to help their web visitors enable Global Privacy Control (a Universal Opt-Out Mechanism for browsers) and OptOutCode to extend their protections beyond to web to apps and IoTs they connect to.
