TrackerControl allows users to monitor and control the widespread, ongoing, hidden data collection in mobile apps about user behaviour ('tracking').To detect tracking, TrackerControl combines the power of the Disconnect blocklist, used by Firefox, and our in-house blocklist is used, created from analysing ~2 000 000 apps! Additionally, TrackerControl supports custom blocklists.This approachreveals the companies behind tracking,allows to block tracking selectively, andexposes the purposes of tracking, such as analytics or advertising.The app also aims to educate about your rights under Data Protection Law, such the EU General Data Protection Regulation (GDPR).Under the hood, TrackerControl uses Android's VPN functionality, to analyse apps' network communications locally on the Android device. This is accomplished through a local VPN server, to enable network traffic analysis by TrackerControl.No root is required, other VPNs or Private DNS are not supported. No external VPN server is used, to keep your data safe! TrackerControl even protects you against DNS cloaking, a popular technique to hide trackers in websites and apps.TrackerControl will always be free and open source, being a research project.

Explore beyond the reaches of the Internet with Trail Sense. Designed for hiking, backpacking, camping, and geocaching Place beacons and navigate to them Use as a compass (only available on devices with a compass sensor) Follow paths Retrace your steps with backtrack Use a photo as a map Plan what to pack Be alerted before the sun sets Predict the weather (only available on devices with a barometer sensor) Use your phone as a flashlight And much more! Trail Sense is a tool, and just like any other tool that you bring into the wilderness, it's essential to have backup equipment and skills. This app is intended for information purposes only and the accuracy of the predictions and sensors are determined by a number of factors, including calibration, sensor quality, external sources, etc. Use at your own risk, always have backup tools (ex. compass), and stay safe. This app also does not, and will never, use the Internet - all information in Trail Sense comes directly from your phone's sensors, and no data will leave Trail Sense. COMMON ISSUES No compass: If your phone does not have a compass sensor, there is nothing I can do to make it work because that is hardware. You will still be able to use other features of Trail Sense. No weather: The Weather tool is only available if your phone has a barometer sensor. Found an issue or want a new feature? Contact me at trailsense@protonmail.com or create a new issue on GitHub: github.com/kylecorry31/Trail-Sense I'm the only developer of Trail Sense, so I will do my best to help out with issues - but I have a limited device selection to test on. PERMISSIONS Notifications: Allows Trail Sense to display notifications (backtrack, weather, sunset alerts, astronomy events, water boil timer, etc) Location: Allows Trail Sense to retrieve your location for navigation, weather (sea level calibration), and astronomy. Background location: Allows Trail Sense to retrieve your location for sunset alerts while in the background. On some devices, this will also improve the reliability of backtrack and weather monitor. Physical activity: Allows Trail Sense to use your phone's pedometer for distance calculation. Camera: Allows Trail Sense to use your camera on the sighting compass, clinometer, and for taking photos used by the Cloud Scanner, QR Code Scanner, and Photo maps. Alarms & reminders: Allows Trail Sense to post a notification at an exact time. This is used by the Clock tool (when updating system time) and Sunset and Sunrise Alerts.
