Todo List (PFA)
APK
The Privacy Friendly To-Do List can be used to keep outstanding tasks in mind and organize a personal schedule. This application allows to create lists of tasks which can be individually managed. Each list contains a set of tasks. Each task can have a deadline, a reminder time and a list of subtasks. By setting a reminder time the user will be informed by a notification. It is possible to display all tasks in a calendar, to protect the app with a secret pin and to sort and prioritize tasks within a list. Colors indicate the urgency of a task (taking the deadline into account). Features of Privacy Friendly To-Do List 1. PIN protection Open the Settings menu to setup a PIN protection for your application. The PIN needs to be a number with 4 digits. You are asked for it every time you start the application / start the main view. 2. Reminder You can set a reminder to your tasks that will notify you if a deadline is approaching. Settings provide you the possibility to enable a notification sound. 3. Widget In addition, this app provides a widget that you can add to your device’s home screen. The widget presents you tasks that belong to a chosen list. Clicking on a task or its checkbox leads to the main view of Privacy Friendly To-Do List. 4. Progress by subtasks By default, progress can be chosen freely by the user when creating or editing a task. To-Do List gives the opportunity to automatically compute and show the progress of a task dependent on its done subtasks. Therefore go to Settings and enable progress by subtasks. Our Privacy Friendly App differs from other applications with respect to three aspects: 1) Minimal permissions Privacy Friendly To-Do List does not use more permissions than are strictly necessary to provide its functionality. 2) No advertisement Privacy Friendly To-Do List completely relinquishes advertisement. Many other free apps in the Google Play Store dazzle annoying advertising which also shortens battery life. 3) No tracking Privacy Friendly To-Do List does not use any trackers. Privacy Friendly To-Do List is part of the Privacy Friendly Apps group developed by the research group SECUSO at Karlsruhe Institute of Technology.
