This app will track all your cryptocurrencies in one place and let you know how much they are worth converted to fiat money.The important thing for the user is that this app is going to ensure 100% trust. It will not require any login/registration process. It won’t collect users’ data by sending it to the server. Users’ provided data about cryptocurrency investments will be only stored inside a local database that is kept inside an Android device. However, to know the portfolio’s value converted to the fiat money, the app is going to use the Internet to get the latest conversion rates.As the topic of money for people is so sensitive, to ensure trust, this app. is being developed openly by creating blog posts series and making the project code available so everyone can see that there is nothing to hide.

Communicate securely and independent, regardless of the legal situation or whether messengers use E2EE. No server needed. #ChatKontrolleStoppen Why KryptEY? Breaking of end-to-end encryption (E2EE) by laws such as the planned EU chat control is an ongoing issue. Content in messengers that use E2EE, such as Whatsapp or Signal, could thus be monitored by third parties. E2EE is often, but not always, standard in messengers. There are proven methods for E2EE such as PGP. However, these methods are sometimes cumbersomely integrated and require a lot of effort to use. KryptEY is an Android keyboard that implements the Signal protocol. The keyboard works messenger-independently and both the X3DH Key Agreement Protocol and the Double Ratchet Algorithm work without a server, thus it enables a highly independent use of the protocol. Features Based upon Simple Keyboard ( https://github.com/rkkr/simple-keyboard ), KryptEY adds a view above the Keyboard for the E2EE functionality. * use E2EE through Signal Protocol in any messenger * encryption/decryption of messages * enter message through separate text field in keyboard * use clipboard to read messages * manage contacts in own contact list in keyboard * message log to view sent/received messages * send messages as plain JSON (raw mode) or hidden in a decoy text (fairytale mode) * verification of E2EE functionality via fingerprint * Q&A View for questions * dark & light theme See https://github.com/amnesica/KryptEY/blob/master/KRYPTEY.md for further information on how KryptEY is working. Security The existing security properties for the Signal Protocol are also valid for the keyboard. Limitations The keyboard was designed as a POC and only allows 1-to-1 conversations. However, the application can also be used in a group chat to a limited extent. Here, a message can be directed to a specific chat partner and not to all people. Other participants of the group chat cannot decrypt the message. Text messages in Telegram are getting copied as HTML and not as plain text. When decoding the message with the fairytale mode the copied message is compromised and can't be read properly. Therefore, it can't be decoded at all. However, the raw mode works properly. When using KryptEY with Telegram we recommend the raw mode. Some messengers like Threema only allows up to 3500 bytes per message. Therefore, different character input limitations apply. To stay under the 3500 bytes limit, only 500 characters are allowed for raw and fairytale mode. For convenience these limitation applies for all messengers. Demo For a demonstration on how KryptEY is used see https://github.com/amnesica/KryptEY/tree/master#demo KryptEY was created by mellitopia and amnesica. The code is open source and can be found at https://github.com/amnesica/KryptEY

筷字输入法 (Kuaizi IME) is a system based on the combinatorial features of Chinese Pinyin. It is an efficient and fast input method editor, suitable for electronic touchscreen devices. 筷字输入法 (Kuaizi IME) abandones the traditional method of tapping on virtual keyboard keys one by one, it instead offers a swipe input method for Pinyin, combined with the combinatorial features of Pinyin letters. The key layout is designed to make Pinyin input more accurate and convenient. 筷字输入法 (Kuaizi IME) provides editing support such as cursor movement and text selection for the target editor, thereby eliminating the frustration of being unable to accurately position inputs and text due to the small screen size of mobile devices. This further enhances text input and editing efficiency on small-screen devices. User-data generated by 筷字输入法 (Kuaizi IME) is stored locally. It does not connect to the internet and will not collect nor analyze user data or behavior habits. Furthermore, it does not support or provide predictive input nor fuzzy matching mechanisms. To some extent, this input method editor aims to enhance the users' ability to recognize and memorize Chinese characters and Pinyin, ensuring that the reliance on digital tools does not lead to the gradual forgetting and eventual abandonment of 「汉字」(Hànzì, Chinese characters), a treasure of Chinese civilization.

Kvaesitso is a launcher application for Android which replaces the device's default home screen.
