Subtitle Blocker
APK
This super-niche application was developed purely to deal with a strong dislike of the fast-moving, distracting subtitles that are hard-coded into many social media videos and cannot be turned off. When enabled, the overlay can either be docked as a small unobtrusive tab on the side of the screen, or expanded into a resizable, moveable rectangle which can be dragged to cover the area displaying subtitles. Colours, opacity, which edge the tab pins to, and symmetric (centre-anchored) resize are all configurable. Basic operation should be completely obvious: • Tap the chevrons » in the middle of the overlay to collapse it to a side tab. • Tap the tab to expand it again. • Drag any corner to resize. • Drag anywhere else to move. • Triple-tap the overlay to open Settings. You can add the "Sub Blocker" tile to your Android Quick Settings panel (swipe down, tap the edit pencil, drag the tile into your active tiles) to quickly toggle the overlay on and off without opening the app. Feedback and feature requests are welcome.

Sudoku (Privacy Friendly)
APK
Privacy Friendly Sudoku is a logic puzzle game. The goal is to fill the complete board with numbers. Every number may only occur once in every column, row and subsection. Privacy Friendly Sudoku has three different game modes: 1. a 6x6 game field with 2x3 subsections 2. a 9x9 game field with 3x3 subsections 3. a 12x12 game field with 3x4 subsections For each game mode there are four different difficulty levels that are not measured by the number of preset values, but rather by the solving strategies needed to solve the game. The generator always tries to provide a game that has the minimum amount of preset values needed to solve the game. Additionally, users can create their own custom sudokus of arbitrary difficulty for each of the three game modes. Sudokus can be shared with other users by using the available import and export functions. Another community feature is the 'daily sudoku', which is newly generated each day and the same for every user of the app. The app can be used in both light and dark mode. Our Privacy Friendly App differs from other applications with respect to two aspects: 1. The Privacy Friendly Sudoku App does not use any permission. 2. The Privacy Friendly Sudoku App completely relinquishes advertisement. Many other free apps in the Google Play Store dazzle annoying advertising and also shortens battery life.
