How to use the Sandbox

Quick guide to use the HoloGraph sandbox.

Switching modes

Mode switching lets you move between exploration (similar to Mythoskolis HoloGraph) and edit mode, which is required to add people and relations.


Creating people

Each time you create a character, a simple profile is provided: first name (required), last name and birth name (optional - you can disable their display and management in the sandbox settings), as well as an optional portrait that you may upload yourself.


Assisted relation creation

When creating a new character, the sandbox takes the existing context into account. It can therefore suggest relevant sibling, kinship, or co-parenting links based on the characters already present in your family tree.

The same applies to suggested last names, helping maintain overall consistency within your genealogy.


Editing created people

You can modify the information of any character displayed on screen at any time by interacting with the 📝 icon. Clicking on the portrait of a satellite character will also reveal this option, without needing to bring them to the center first.


Editing relations

You can view the existing links of a character by clicking the relationship icon in edit mode (also accessible from a satellite character).

A summary of the relationships will be displayed, allowing you to freely modify or delete them.

⚠️ It is possible to assign multiple different types to a relationship between two characters. This feature is intentional, but should be used carefully depending on what you wish to model. Rest assured: no action can alter or disrupt the proper functioning of the tool.


Creating a relation

Do not create the same character twice in your tree.

If you wish to connect two existing characters, use the relationship creation tool from one of them, then select the other to define the nature of their link.


Search and quick access

Just like the Mythoskolis HoloGraph, you can quickly access the character of your choice using the search field.

Since the sandbox also manages surnames, you can access dedicated overview pages listing everyone associated with a specific family name, whether it is a birth name or not. You can also quickly navigate to these characters by clicking on their badge.


Statistics

The menu also gives you access to general statistics about your tree. For completionists, this window makes it easy to identify characters who do not yet have a portrait.


Save and import

The sandbox allows you to save your work so you do not have to start from scratch. The tree and portraits remain on your device; saving and importing them are local operations. Optional PIN recovery uses an email code delivery service, described below.

By default, no data is transmitted and the tool is directly accessible without any registration form. Your data belongs to you, and you may use your real names and photos if you wish: Mythoskolis will not make any use of them. Only the optional PIN-recovery feature sends the email address to the delivery service when a temporary code is requested; the tree and portraits never leave the device. In return, Mythoskolis declines all responsibility for any fraudulent or defamatory use that may result from the sandbox.


Protecting changes with a PIN

From the sandbox menu, choose Protect this sandbox and set a 4-to-8-digit PIN. Exploration remains freely available, but entering edit mode, importing a file, and starting over require the PIN while the session is locked. You can lock the session again at any time from the menu or options.

The PIN and your data remain on your device. Only a verifier derived from the PIN is stored; the PIN itself is never saved in plain text. Reloading the page locks the session again.

You may optionally add a recovery email. An initial 6-digit code verifies that the address belongs to you. If you later forget the PIN, another one-time code lets you define a new PIN—the old one is never sent or revealed. The address itself is not stored in clear text in the sandbox or its exports: only its hash, an opaque identifier, and a verification proof are retained. No account is created and no genealogy data is sent to the server.

When exporting a protected sandbox, you can keep the lock in the .myth file or create a shareable copy without it. Creating that copy does not alter the sandbox currently open.

This lock is mainly intended to prevent accidental changes: it does not encrypt the file contents. Without a verified email, Mythoskolis cannot reset a forgotten PIN. “Forgot your PIN?” then opens the advanced options; permanent erasure follows a separate flow requiring ERASE and a final confirmation.


Voluntary model limitations

The sandbox is based on a simple principle: only direct relationships can be created (parent, child, sibling, union).

More distant relationships (grandparents, cousins, uncles, etc.) are not created directly, but naturally emerge from the chain of direct links. This choice ensures a genealogy that remains clear, consistent, and scalable.


A space for experimentation

The sandbox is designed as a space for exploration and experimentation. You can test, modify, delete, and rebuild your trees freely, without any risk of “breaking” anything.

The goal is not immediate perfection, but a progressive understanding of your genealogy.
