Tweek is a minimal planner and to-do app for iPhone, iPad, Mac and Android. It opens in a weekly view by default, with month and day views also available. Google, Outlook and Apple calendars appear alongside tasks. Tasks can carry colour tags, subtasks, notes, files and images, recurring schedules and reminders, and task sets can be shared through a link. The service works with an account, and the privacy policy states that the company stores the content users create.
Tweek is operated by SIA SCADA, based in Riga, Latvia, so the operator is an EU company subject to the GDPR. The privacy policy's list of sub-processors, however, places hosting with Digital Ocean and Google Cloud in the United States, and no European hosting option is named. An organisation that needs task data kept within the EU should ask the vendor to confirm where each data category is stored, and weigh the US cloud exposure this implies before adopting the app for work.
