Player support

Let’s keep your collection safe.

For gameplay, progress, account, or accessibility help, contact Nestarium Support.

Email support

Include your device, browser or app version, what happened, and what you expected. Redact personal information from screenshots. Never send passwords, sign-in codes, authentication tokens, payment details, or a full save unless support specifically requests it.

Before troubleshooting a save

Do not clear browser data, uninstall, remove a player, or import a different save while investigating missing progress. Those actions can remove the only usable local copy.

Where is my progress saved?

Nestarium saves progress on your device. Supported private-test builds can also synchronize core progress to a cloud copy associated with that installation. A guest cloud identity is not necessarily recoverable after the browser or installation is lost.

How do I back up or transfer a save?

Open Settings → Account & Saves and use Export Save. Keep the file private. Import replaces saved data at the destination, so export that device first. Exports do not transfer authentication credentials.

How do I report a problem?

Describe the screen and action involved, whether it repeats, and any visible error. A redacted screenshot can help.

How do I request or remove cloud data?

Removing a local player does not automatically delete cloud records. See account and data requests before removing local information that may help identify the account.
