# SIS

This is a basic Android app, which loads [the website of SIS CUNI](https://is.cuni.cz/studium/) (using [WebView](https://developer.android.com/reference/android/webkit/WebView.html)) and injects custom styles and scripts to make the website more mobile- and user-friendly.

This app does NOT collect usernames, passwords, personal information or any other data. [Privacy Policy](./PRIVACY.md)

*Note: Some things may be hidden or may not work.*

## Screenshots

*Note: The elements that appear cut off in the screenshots are, in fact, horizontally scrollable. \
(Czech version is shown, but switching to English is possible.)*

## Download

The app [was on Google Play in the past](https://web.archive.org/web/20250521154946/https://play.google.com/store/apps/details?id=io.github.sykoram.sis), but my developer account has been deleted because I didn't want to send my ID to Google.

At the time of removal (2025-05-21), the app had been installed on 1.7k devices and had rating of 4.8 stars (21 reviews, [6 comments](#feedback)).

To download the app, use one of the options below:

### Option 1: Obtainium (preferred way, automatic updates)

You need to have [Obtainium installed](https://wiki.obtainium.imranr.dev/). Then, click the following:

### Option 2: F-Droid (also preferred way, automatic updates)

[Get it on F-Droid](https://f-droid.org/packages/io.github.sykoram.sis)

### Option 3: direct APK download (you must update manually)

Download the APK file from [Releases](https://github.com/sykoram/sis/releases) → Assets → app-release.apk.

To install it, "Install apps from unknown/external sources" option has to be enabled in your Android. This option should be found somewhere in settings. You can try: \
"Settings → Apps & notifications → Special app access → Install unknown apps" \
"Settings → Security → Unknown sources"

Open the downloaded APK file and you should be able to install it. You might see a "Blocked by Play Protect" message, because I'm not a verified developer and the app is not being installed from Google Play.

## Project Installation, Build and Run
