Unless your device has pre-installed software for this, you will need to install an e-reader app for viewing the eBooks and an audio player to listen to audiobooks.
Important: if you are having problems opening the eBooks, this is very likely because your eReader software has trouble opening the EPUB files (which are contained within the app and copied to the SD card to make them available to other software), for whatever reasons. If this keeps happening, please try a different eReader software (such as the free Aldiko reader) and check in your system settings which app is configured for opening EPUB eBooks by default.
Also please email me email@example.com if you're having any problems using the app.
This app needs permissions to access the internet in order to download the audio recordings and write access to external storage (SD card) to export resources to make them available to other (viewer) apps. Cthulhoid doesn't use ads and doesn't record or transmit any usage or user data.
Content and user interface of this app are english only! Please don't give me a hard time because the stories are in english, I'm not a translator and translated versions are usually not in the public domain.
