Stop dealing with overbooked events, broken choice limiters, and paying recurring monthly subscriptions just to cap form responses.

ChoiceGuard dynamically limits options and manages capacity across Google Forms directly within your workspace. Built with a concurrency-safe locking engine, ChoiceGuard prevents double-booking and race conditions during simultaneous sign-ups — whether you are managing classroom workshop seats, event RSVP slots, or limited inventory orders.

Everything runs 100% inside your Google account. Zero external server hops, zero data brokers, no ads, and no recurring monthly or annual rent.

WHAT IT DOES

  • Dynamic Choice Elimination: Assign exact limits to any Multiple Choice, Dropdown, or Checkbox question. As respondents submit, exhausted choices disappear from future forms in real time.
  • Concurrency Mutex Protection: Built on Apps Script's native LockService, ensuring simultaneous submissions never exceed your hard caps or cause race-condition overbookings.
  • Automated Form Gatekeeping: Automatically close the form with a custom friendly notification once all session options or inventory items are filled.
  • One-Click Inventory Reset: Restore all original choices and reset response counters instantly when launching a new registration cycle.
  • Native Editor Sidebar: Manage question limits directly alongside your form questions without switching between external management portals.

WHY IT'S DIFFERENT

Most form-limiting add-ons in the Google Workspace Marketplace operate as subscription cash registers — charging recurring monthly fees for basic counting scripts. Even worse, many transmit your respondent lists and form entries to third-party servers to process counters, introducing major compliance and data privacy risks.

ChoiceGuard is built on local-first principles: your form responses never leave your Google session. The counting, state management, and option modifications occur entirely within Google Apps Script and your document properties.

SOVEREIGN OWNERSHIP — ZERO SUBSCRIPTIONS

We do not believe in renting tools you use to manage basic business operations. ChoiceGuard is available as a one-time lifetime license. Pay once, use it for life across your Google account. Never a recurring monthly or annual fee.

RADICAL PRIVACY & MINIMAL SCOPES

ChoiceGuard requests only non-sensitive currentonly scopes (forms.currentonly). It only has access to the active Google Form where you explicitly open it. It cannot read your Google Drive, inspect other forms, or access private email messages. Period.
