Unofficial DM Screen Connector Privacy Notice
Effective September 6, 2026
The connector handles selected game-page data only when you request a sync. It transfers that data only to the hosted or native Dungeon Master Campaign Console you are using. It does not collect D&D Beyond or Roll20 credentials, operate an analytics or advertising service, or send game data to the developer for independent use.
Purpose
The connector has one purpose: keeping one Dungeon Master's own tabletop tools in sync. It moves user-requested campaign, character, initiative, inventory, note, homebrew, and dice-roll data between the DM Screen, supported D&D Beyond pages, Roll20, and the local Loremaster's Compass desktop app. It can apply reviewed journal or inventory changes, or create a private D&D Beyond magic item, only after the user chooses the corresponding action.
Data access
- D&D Beyond: the supported character, campaign, or private homebrew editor page URL and identifier plus visible character names, statistics, conditions, inventory, coin containers, equipped or attuned items, campaign rosters, tagged DM notes, and user-entered magic-item builder fields.
- Roll20: visible Turn Order names and initiative values, plus local Compass dice text that the user asks Roll20 to resolve.
- DM Screen: the requested sync command, its result, and the game data needed to update the active table profile.
The connector does not read or copy passwords, browser-saved credentials, cookies, authentication tokens, payment details, private messages, unrelated browsing history, or content from unsupported websites.
Data handling
- Hosted DM Screen: requested results pass from the connector to the open DM Screen page and may be saved in the user's active DM Screen profile. The hosted console and its infrastructure providers process that profile data only to provide the console.
- Native Windows DM Screen: requested results pass through a relay bound to
127.0.0.1on the same computer and are stored in the user's local profile. - Loremaster's Compass dice: only while a Roll20 chat box is on screen, the connector can poll a local-only Compass relay on
127.0.0.1, ports 21356–21358, and post the dice text the user sees into that chat. This connection cannot leave the device. The connector never reads or writes the clipboard. Roll20 performs the roll natively; the connector does not calculate or invent a result. - D&D Beyond updates: approved changes are applied inside the signed-in D&D Beyond page; account credentials remain in Chrome and are never copied to the DM Screen.
The extension itself retains no separate copy after a request completes. DM Screen snapshots and notes remain in the selected hosted or native profile. The connector does not sell or transfer data for independent purposes, use it for advertising or creditworthiness or lending decisions, or allow the developer to read it except with the user's explicit consent for a specific support request, as necessary for security, or as required by law. Its use of information received from supported pages adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements.
For supported character and campaign requests, Chrome may load a selected D&D Beyond page in a temporary inactive tab so the connector does not switch away from the user's current page. The temporary tab closes after the request. D&D Beyond writes use the signed-in page workflow and report their verification result in the console.
User control
Chrome displays the requested permissions before installation. Nothing is scanned until the user selects a sync control. Each write reports its verification result in the console. Removing or disabling the connector in Chrome immediately ends its access to supported pages.
Independent, unofficial tool
The DM Screen connector and Loremaster's Compass bridge are independent, unofficial tools. They are not affiliated with, endorsed by, or sponsored by Google, D&D Beyond, Wizards of the Coast, Fandom, or Roll20.
