# Recommendations ## Recommended Technical Specifications All of Tactyc computations are done in software code (i.e. JavaScript/TypeScript) and on your browser. The speed and performance of your user experience depends heavily on your browser version. We recommend using the following browsers for Tactyc: * Google Chrome: 55 and higher * Safari: 49 and higher * Firefox: 10 and higher Given Tactyc's quantitative heavy dashboards, mobile devices are not fully supported currently. Please use Tactyc in a desktop environment. ## **Concurrent Users Warning** If multiple users are concurrently are simultaneously changing data for a fund, Tactyc will honor the **last saved** changed for an investment or a fund. This might result in not all the changes being captured if one of the users does not have the latest session data. **Recommendation:** Please avoid having multiple users change data at the same time. The best practice is to have one single user editing at a time, while other users are viewing in read-only mode. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
