Terms of Service

1. What this is

EggLedger exports Egg, Inc. spaceship mission history, including per-mission loot, to .xlsx and .csv, and lets you browse, filter, and chart that data. It ships in two forms:

• Desktop app. Windows, macOS, and Linux. Your mission data stays on your own machine.
• Web app. A hosted instance. Your mission data is decoded and stored on the server under your account.

You are using the hosted web app, so the Web app section below applies to you.

It is not a game client, a cheat, or a service operated by the game's authors. EggLedger was originally created by mk2 and is now developed and maintained by an individual, David Cole, not a company.

2. Provided as-is, no warranty

The software is licensed under the MIT License (Copyright 2026 David Cole). As that license states, it is provided "as is", without warranty of any kind, express or implied. The hosted web app and the optional Settings Sync service are offered on the same basis. There is no guarantee they will be available, uninterrupted, accurate, or fit for any particular purpose. You use them at your own risk.

3. Accounts and signing in

Signing in is handled by EggIdentity, a separate federated authentication service run by the same operator. You pick a sign-in source: Discord, Google, Microsoft, or GitHub. EggLedger never sees or stores your password.

EggIdentity has its own terms and privacy policy, and they govern the login itself. Keeping your sign-in source secure is your responsibility. The web app requires an account. The desktop app needs one only if you turn on Settings Sync.

4. Acceptable use

When you use EggLedger or its hosted services, you agree not to:

• Send unwanted or excessive load to auxbrain.com, or use this tool to attack, overload, or disrupt the Egg, Inc. API or any other system.
• Use the tool to violate Egg, Inc.'s own terms of service or the rules of the game.
• Attempt to circumvent authentication or access controls on any hosted service.
• Use the service to harm others, to distribute malware, or for any unlawful purpose.

EggLedger talks to the Egg, Inc. API the same way the game's own community tools have for years. That access exists for legitimate interoperability and personal data export, not as a licence to attack a third party's servers. If you run your own build of the software, the same expectations of responsible use apply, and you are responsible for how you use it.

5. No account risk warranty

No community tool, including this one, is sanctioned by the Egg, Inc. developer. The operator is not aware of any negative effects from using EggLedger, and the same read-only API access has been used safely by other community tools for years. Even so, this is not a guarantee, and you use the tool at your own risk.

6. Desktop app

The desktop app stores config, mission data, and exports next to its own binary. Nothing is uploaded unless you turn on Settings Sync. Keeping your own backups of that directory is up to you, and the operator cannot recover data you delete or lose.

7. Web app and stored data

The hosted web app decodes your Egg, Inc. backup on the server and stores the result in its database under your account. That covers your mission history, drops, backups, settings, and reports. The data is kept until it is deleted.

Disconnecting in settings deletes your synced settings and signs you out; it leaves your stored mission data in place. Deleting the account removes everything stored under it, and that is done by asking the operator. The hosted app is a convenience, not a backup service, and the operator gives no guarantee that stored data will survive an outage or a change to the service. The Privacy & Cookies page describes exactly what is stored and how to remove it.

8. Supporting the project

Supporting the project is entirely voluntary. Donations are handled by third-party platforms (GitHub Sponsors, Patreon, and Buy Me a Coffee). This application never processes or stores your payment card data. Refunds, billing, and cancellation are governed by the platform you paid through, not by this service.

9. Changes to the service

This is a personal project. The operator may change, suspend, or discontinue any part of the service, including the hosted web app and Settings Sync, at any time and without notice. These terms may also be updated. Continued use after a change means you accept the updated terms. The open-source code remains available under its licence regardless of what happens to any hosted service.

10. Limitation of liability

To the fullest extent permitted by law, the operator is not liable for any damages arising from your use of, or inability to use, the software or any hosted service. This is a free tool maintained in spare time. The MIT License's limitation of liability applies, and the same spirit applies to any hosted service: you accept all risk of using it.

11. Contact

Questions about these terms can go to the operator through the project's GitHub repository or the project Discord server.
