We build official companion apps for indie tabletop and RPG publishers — designed, built, and published under your brand. Zero cost. Zero risk. Pure upside.
Don't imagine the end product — hold it. Every app here is real, built by DigiRune, and either live in the stores or on its way.
A universal tool for every tabletop RPG — scan any paper character sheet into a clean, editable digital character.
Official field companion for MERCS 2.5 — built with Fifth Angel Studios.
Official companion for Twisted: Steampunk Skirmish — built with Demented Games.
We're not a consultancy quoting a budget. We build, publish, and maintain the entire app at our own cost — you bring the game and share the upside.
DigiRune covers all development, store publishing, maintenance, and support. You bring the IP and the community — nothing more.
Keep 30% of every sale — passive income on a product you never build, launch, or maintain.
Every app is built for your game and published under your name — an official companion that's unmistakably yours.
Expansions, updates, store policy, bug fixes, support — all handled. Your only job is telling your community it exists.
Simple by design. Publishers bring the IP and the community. DigiRune handles everything else.
A straightforward revenue share. You keep 100% of your IP; we license it to build and publish under your brand.
We build to your game's full depth. You review and approve everything before it goes live. Usually five to six weeks from start to submission.
Live on both stores under your branding. We maintain it; you announce it and collect your share — indefinitely.
Every DigiRune app comes out of The Forge — our internal build process with a quality gate at every step.
Your rules go in word-for-word. Nothing paraphrased, nothing invented — every stat and line checked against your source.
Tested on real phones and tablets — iOS and Android, online and offline — before you ever see it.
Your community's first impression is the one that counts. We build for a launch with zero excuses — then keep it that way.
DigiRune is run by Will McCullough — Marine Corps veteran, 25-year entrepreneur, developer and lifelong tabletop gamer.
Combat Engineer. Senior Drill Instructor. Broker-owner who represented 1,000+ real-estate clients and brought the first-ever UFC event to South Carolina as Governor-appointed Chairman of the State Athletic Commission. Roles where precision, accountability, and attention to detail were never optional — the same standard baked into every app DigiRune builds.
What that means for you: your IP is in experienced, accountable hands — someone who has built businesses from scratch, navigated regulation, and delivered under pressure for decades.
Twisted is live. Sheetmancer and MERCS are next. Yours could follow.

will@digirunestudios.com This policy describes how McCullough Development, Inc., doing business as DigiRune Studios ("DigiRune Studios," "we," "us," or "our"), handles information across this website and our companion applications. Individual apps may include their own supplemental privacy details at the point of download.
DigiRune Studios is a division of McCullough Development, Inc., a South Carolina corporation based in Beaufort, South Carolina, United States. We build official companion applications for indie tabletop and role-playing game publishers, along with freestanding tools for the broader tabletop community.
We aim to collect as little as possible. Depending on how you interact with us, this may include:
We do not sell your personal information, and we do not use it for third-party advertising.
Our applications are distributed through the Apple App Store and Google Play. When you purchase an app, the transaction is handled entirely by Apple or Google under their own terms and privacy policies. We do not receive or store your payment card details.
We rely on a small number of trusted providers to operate our services: static web hosting for this site; Apple and Google for app distribution and purchases; Google Firebase (Authentication and Cloud Firestore) to provide optional cross-device sign-in and synchronization in applications that offer it; and certain optional in-app features, such as on-demand translation, that may send the text you choose to translate to a third-party service only when you actively use that feature. In applications that offer image-to-text or similar AI-assisted features, we use an AI processing provider (Anthropic, maker of the Claude models), relayed through a secure server we operate (Cloudflare), which receives only the content you submit for that feature and returns the extracted result. Under Anthropic’s commercial API terms, content sent through the API is not used to train its models and is automatically deleted after a short retention period. Each provider processes information under its own privacy policy.
We keep correspondence and contact information only as long as needed to address your request and to maintain reasonable business records, after which it is deleted or archived. Information stored locally within an app remains under your control and can be cleared from your device at any time. If you use optional sign-in to sync data across devices, that information is retained while your account remains active; you can clear it or delete your account at any time from within the app or by contacting us, after which the synced data is removed.
Our website and applications are intended for a general audience and are not directed to children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us and we will take appropriate steps to delete it.
You may contact us at any time to ask what information we hold about you, to request a correction, or to request deletion of information you have shared with us. Depending on where you live, you may have additional rights under applicable privacy laws, and we will honor those rights as required.
We may update this policy from time to time. When we do, we will revise the "Last updated" date above.

If you signed in to a DigiRune Studios companion app using your Google or Apple account, you can request deletion of your account and all associated synced data at any time. Signing out within the app ends your session on that device, but does not by itself delete data stored in our systems.
To permanently delete your account and data, email will@digirunestudios.com from the email address associated with your account, using the subject line Account Deletion Request. We will permanently delete your account identifier (such as your email address and unique user ID) and any preferences or content you chose to sync, within 30 days, and confirm by email once complete.
Information stored only on your own device can be cleared at any time from within the app. We retain no synced data after deletion, except where retention is required by law.
