In short: Slidethrum does not collect, store or transmit any personal data.
The apps work completely offline: the game and the puzzle images are part of the app. There is no registration, no account, no analytics or tracking, no advertising and no sharing of data. The apps do not connect to any servers on their own. At most your game settings and best results are stored, on the device only; deleting the app removes them.
The web app is loaded from appsthrum.com; the web server processes technically necessary access data (IP address, time, requested file) in its logs. The chosen language, game settings and best results live in your browser's local storage and never leave it. So the game works offline, the browser keeps the web app's files in its cache. The web app sets no cookies and contains no analytics or advertising services.
The information pages at appsthrum.com/slidethrum/ use a self-hosted Matomo statistic without third-party cookies. Linked pages (appsthrum.com, schiebepuzzle.com, EÖDL, publisher) are subject to the notices there.
Slidethrum is a project of Dyslexia Research Center USA. The puzzles come from schiebepuzzle.com by the EÖDL.
