About One-Shot Architect

How it works

  1. Start with three generated concepts, or choose Make Your Own Adventure to open a blank workbench.
  2. Choose party power, setting, theme, objective, conflict, signature mechanic, and tone directly from the curated library. Lock anything you want to preserve and let One-Shot Architect fill the rest.
  3. Use the sliders to shape how the session should play, including combat, roleplay, investigation, exploration, puzzles, danger, and complexity.
  4. Export one Adventure Outline designed to give a GM the complete situation, key people, scene progression, discoveries, pressure, signature set piece, climax, outcomes, runtime cuts, and scaling guidance in a concise form.

Privacy & storage

One-Shot Architect works offline and stores projects locally on this device. Adventure and project contents are not sent to Nat 1 Nerds. If you purchase Unlimited, the applicable app store and RevenueCat process purchase and entitlement status; they do not receive your adventure content. Export a Project Backup (JSON) whenever you want a portable copy.

Generation

Adventures are built locally from a curated content library and your selections. The same seed and controls reproduce the same outline, and no project data needs to leave your device.

System-agnostic by design

One-Shot Architect is designed to work across tabletop roleplaying systems. It deliberately leaves out rules-specific target numbers, stat blocks, classes, spells, damage formulas, and proprietary game mechanics. Party Power sets the narrative scale of the adventure; the GM translates exact difficulty and statistics into the system being played.

Privacy Policy

Effective August 31, 2026

Short version: Your adventure content stays on your device unless you choose to export or share it. One-Shot Architect has no ads or behavioral tracking. App-store purchase and entitlement status is processed only to provide Unlimited access.

Adventure and project data

Projects are stored locally on your device and generated adventure outlines are created on-device. Nat 1 Nerds does not receive the contents of your projects, prompts, outlines, or exports.

Free usage meter

The app stores a small local record of how many new adventures have been created during the current calendar month so it can provide the free allowance of three adventures per month. This record contains no adventure text and is not transmitted to Nat 1 Nerds.

Purchases

If you buy Monthly Unlimited or Lifetime Unlimited, payment is handled by Google Play. RevenueCat is used to verify purchase and entitlement status across installs on the same store ecosystem. Purchase records may include store product identifiers, transaction status, entitlement status, and an anonymous app-user identifier. Adventure content is never sent with purchase information.

Other collection

The app does not require a Nat 1 Nerds account and does not include advertising, behavioral analytics, cross-app tracking, cloud project synchronization, location access, contacts access, or background collection of adventure data.

Exports and sharing

When you export or share a PDF, Markdown file, or project backup, the destination is chosen by you through your device or browser. Those files are not automatically sent to Nat 1 Nerds.

Support

If you voluntarily contact Nat 1 Nerds for support, any information you choose to include in that message is handled only for the purpose of responding to your request.

Deleting project data

You can delete saved projects individually or use Delete project data in the About screen to remove One-Shot Architect projects and ordinary app preferences from the device. The current-month free usage meter is retained until its normal monthly reset so this control cannot be used as a free-limit reset. App-store purchase records are managed by the applicable store.

Changes

If future versions add services that change these practices, this policy and the relevant store privacy disclosures must be updated before those services are released.

Help & Support

Before contacting support

  • Save a Project Backup (JSON) if the issue involves a specific project.
  • Copy the Support Reference from the About screen when an adventure has been generated.
  • Include the app version and build shown in About.

Common fixes

  • If a project appears missing, open Projects and check the local project library.
  • If an export does not open automatically on mobile, use the system share sheet to save it to Files, Drive, or another app.
  • If Unlimited is missing after reinstalling or changing devices within the same store ecosystem, open About → Plan & purchases → Restore purchases.
  • If a monthly subscriber wants to cancel or change renewal, use Manage subscription in the Plan & purchases section.
  • If project data needs to be cleared, export anything you want to keep before using Delete project data.

Contact

Use the Nat 1 Nerds support contact provided in the App Store or Google Play listing. Include your Support Reference when possible.

The free plan is permanent. You receive three new adventures each calendar month. Rerolling, editing, reopening, duplicating, importing, and re-exporting existing projects do not consume another free adventure.

Website purchases

Restore with a purchase code

Paste a code saved from a website purchase. This switches the purchase used by this browser.

Purchase codes restore paid access. To move your adventures too, export and import a Project Backup (JSON). Android purchases still use Google Play restoration.

Local data

Delete project data?

This cannot be undone. All locally saved One-Shot Architect projects and ordinary app preferences on this device will be removed. Your current-month free usage meter and app-store purchase record are not reset. Export project backups first if you want to keep them.
