Nametag is developed as open source and is officially provided as a service. For free, you can manage up to 50 people and up to 10 groups. To get started for free, click 'Start for Free.'

You can use it by linking your Google account or by registering your name, email address, and password. This time, enter your name, email address, and password and click 'Sign in.'

Once your account is created and you have successfully signed in, click 'Create your first person.'

Register information about people who are related to you. First, enter 'Name,' 'Known Through,' and 'Relationship to You.' The 'Relationship Node' is the person who connects you to that person, and is set to 'You' by default. For 'Relationship,' select friends, partners, family, etc.

Enter the date you last met in 'Late Contact' and important dates such as wedding anniversaries and birthdays in 'Important Dates.' Once you have entered all the information, click 'Create' to register the person.

As you register people, Dashboard will display a simple graph of their relationships with you.

You can also register 'friends of friends' by entering the name of a friend in the relationship node, as shown below. Even if you don't have a direct relationship with someone, you can record their relationship by registering them as 'my wife's mentor,' 'my boyfriend's friend,' or 'my sister's acquaintance.'

'Groups' allows you to create and manage groups that bring together registered people.

'Relationship Types' allows you to manage relationships between people.

The Personal plan, which costs $1 per month (about 158 yen) / $10 per year (about 1580 yen), allows you to register relationships with up to 1,000 people and up to 500 groups, and all functions can be used. The Pro plan, which costs $2 per month (about 320 yen) / $20 per year (about 3,200 yen), unlocks all restrictions and allows you to preview new features.

Furthermore, Nametag's source code is available on GitHub under the AGPL-3.0 license. If you set up the environment on your own server, you can use all functions free of charge and without any restrictions, and there is no need to register for email services.
