Where is my data saved? (Security Issues)

The Importance of Data Security in Web-Based Gantt Charts

A company's core project schedules, new product launch plans, and internal resource allocations are mostly highly confidential. Although many companies are adopting cloud-based collaboration SaaS (Software as a Service) tools, there are still significant security concerns among enterprises and public institutions regarding the transmission and storage of core corporate data on external servers. In this environment, one of the most critical criteria when choosing a project management tool is: "Where is my data physically stored, and who has access to it?"

Rudia Online Gantt's Perfect Local Storage Architecture

To fundamentally block these security concerns, Rudia Online Gantt is designed with a 100% Client-Side Application architecture.

1. Zero Data Transmission to External Servers

Typical web applications communicate with back-end servers and store information in databases whenever a user enters text or changes a date. However, Rudia Gantt is different. All data created on the chart—such as WBS structures, durations, task names, and progress rates—are computed and reside solely within the memory and Local Storage of the web browser you are currently using. No data packets are ever transmitted to Rudia Factory's servers or third-party cloud servers (AWS, GCP, etc.), meaning the possibility of data leaks simply does not exist.

2. Temporary Saving Mechanism utilizing Local Storage

To prevent data loss even if you accidentally close the browser tab or refresh, Rudia Gantt performs real-time temporary saving using the browser's native secure isolated space, Local Storage. This data remains safely on your personal PC's hard drive area even after closing the browser, allowing you to seamlessly continue your work upon your next visit.

Permanent Storage and Secure Sharing Methods (JSON / Excel)

Clearing your web browser's cache or local storage may delete the temporarily saved data. Therefore, when your work is complete or a backup is needed, you must perform an Export to a separate file.

• JSON File Backup (.rudia.net): Click the [Export] button at the top right of the chart to download a JSON formatted data file to your PC. This file can be saved to a USB drive or safely shared with team members via internal secure messengers.
• Excel & PDF Export: For management reporting or sharing with partners, you can convert and save the schedule as Excel or PDF files to your local device.

Rudia Online Gantt is the optimal project management solution that guarantees strict privacy akin to installable software while simultaneously providing the powerful accessibility of the web. Manage your confidential project schedules perfectly without worrying about data leaks.
