Who owns the copyright of outputs (charts, etc.) created with these tools?

The copyright of visualizations you create belongs to you. You are free to publish and use them as you wish.

Can I use outputs (charts, etc.) created with these tools commercially?

Yes. You can freely use them in reports, presentations, papers, books, websites, and more.

Can I save my work?

For data visualization tools, we provide the ability to save your work as a project. These are listed on your dashboard and can be opened with a single click. Other tools (data wrangling, color design) do not have a save function — please download the output for your use.

What is a project?

We call the combination of “your data” and “your work in a tool” a “project.”

Can I start using it right away?

We are currently building and testing the service. We plan to launch around March 2026.

How to Use

Do I need to install anything?

No installation is required. All tools run in your browser. You don’t need any special software — just an internet connection and a web browser.

Do I need programming skills?

No programming is required. You can create charts and process data simply by uploading or entering your data. We’ve designed professional tools to be as simple to use as possible.

What data formats are supported?

Most tools accept data in CSV format. Some tools also support specific formats such as GeoJSON. Each tool’s page lists supported data formats and provides sample data.

Since Excel files can contain various data structures, we don’t support direct Excel uploads. Instead, we provide the versatile data cleansing tool OpenRefine.

Is sample data available?

We offer two types of data portals: sample data bundled with each tool, and original datasets curated based on popular requests.

Pricing & Subscriptions

How much does it cost?

The most basic Standard Plan is ¥2,480/month. Annual billing includes a two-month discount. We also offer a plan that includes one-on-one coaching once a month in addition to tool access.

See the Pricing page for details.

Are subscriptions auto-renewed?

Yes. Using Stripe’s subscription system, your subscription is automatically renewed one month or one year after your payment date, depending on your plan.

Can I cancel at any time?

Yes, you can cancel at any time. After cancellation, automatic payments will stop, and you can continue using the service until the end of your current billing period.

Data Security

Can I use personal or confidential data?

Data used in our tools is generally not stored on our servers, but processing methods vary by tool. Some data visualization tools have a feature to save your work-in-progress, and in those cases data is stored on the server. For all other tools, data is not retained on the server side.

Future Plans

Will more tools be added?

We continuously add and improve tools in this service. We plan to add new data visualization and data wrangling tools on an ongoing basis. Some tools may be modified or discontinued. We welcome requests for tools and datasets, and will accommodate them as much as possible.

Adoption & Organizational Use

Can teams or companies use this?

Yes, teams and companies can use this service. As a suite of tools for streamlining data visualization and data wrangling, it can be used by people in various roles such as analysts and planners. It can also be adopted as a common data tool within a team.

However, a license is required for each user. We offer bulk account registration and volume discounts — please contact us via the Contact page.

Can it be used for corporate training or educational purposes?

Yes, it can be used for educational purposes. It can serve as a tool for learning data visualization and data literacy in university courses or corporate training. Since many of the tools are single-function, they are well-suited as teaching materials for understanding data structures and visualization mechanisms.
