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.

TRANSPARENT FREEMIUM & ONE-TIME PRICING

Free Plan: Manage up to 2 active forms simultaneously with 100% unlimited responses. Zero credit card required.

ChoiceGuard Pro ($29.00 One-Time): Manage unlimited active forms simultaneously across your Google account forever. Pay once, own for life. Zero recurring monthly or annual rent.

RADICAL PRIVACY & DATA TRANSPARENCY

ChoiceGuard operates on a strict local-first architecture. 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.

License Verification Transparency: When activating a Pro license, ChoiceGuard performs a single verification check against api.864zeros.com solely to confirm key authenticity and enforce multi-seat limits. No personal identifiers, Google profile data, email addresses, or form contents are ever transmitted or stored—only the license key and an anonymous, randomly generated installation identifier are processed.
