Privacy Policy

Effective date: July 8, 2026

VellumFE is an open-source client for GemStone IV. This policy covers the VellumFE applications (desktop, terminal, Android, and iOS) published by the VellumFE project.

What we collect

Nothing. VellumFE contains no analytics, telemetry, advertising, or tracking of any kind. The app makes no network connections other than the ones you explicitly initiate: connecting to the game (directly or via Lich), and — only when you run .mapdb download or use the equivalent settings button — fetching map data from GitHub.

Your login credentials

• Your play.net account name and password are used solely to authenticate with Simutronics’ servers (eaccess.play.net) over an encrypted TLS connection, or with a Lich proxy you configure yourself.
• If you enable Remember this login, credentials are stored locally on your device only. They are never transmitted anywhere except to the game servers during login.
• Credentials are removed when you delete the saved login or uninstall the app.

Game traffic

Everything you type and everything the game sends is exchanged directly between your device and Simutronics’ servers (or your own Lich proxy). The VellumFE project operates no servers and cannot see your gameplay. Your interaction with the game itself is governed by Simutronics’ policies.

Local data

Settings, window layouts, highlights, and optional session logs are stored on your device and never leave it. You can delete them at any time from the app or by removing its data.

Third parties

VellumFE embeds no third-party SDKs and shares no data with third parties.

Changes

If this policy changes, the updated version will be published at this page with a new effective date.
