RuneKeys is an iPhone app developed by Pierre Bongen that provides users with a variety of keyboards for writing in runes. The app offers keyboards for both the Elder Futhark and Anglo-Saxon Futhork runic alphabets, allowing users to transcribe English and German texts using these ancient writing systems.

With RuneKeys, users can choose from different keyboard options, including a keyboard for transcribing English, a keyboard for transcribing German, and a pure Elder Futhark keyboard. Similarly, there is also a keyboard for transcribing English and a pure Anglo-Saxon Futhork keyboard available.

One of the notable features of the RuneKeys keyboards is that pressing and holding a key reveals additional characters and symbols related to that specific rune. This includes variations of runes, alternative transcriptions, and related characters, such as numerical variations like 2 and ².

In terms of privacy, RuneKeys follows the principle of data thrift, meaning it only collects, processes, and stores the data that is necessary for the app to function. The app does not require user accounts or ask for personal data. Any data entered within the RuneKeys app stays within the app and is only passed to the operating system for processing, such as inserting the characters into a text field. RuneKeys does not collect or process personal data, and there is no user tracking implemented.
