A focused workflow, not another bulky form builder.

Each FormSuite add-on does one operational job around Google Forms, Sheets, Docs, or Gmail — then gets out of the way.

1

Pick the capacity field

Choose the dropdown, multiple-choice, or checkbox item that represents sessions, roles, or appointment slots.

2

Set each quota

Give every option its own limit and write the message visitors see when it fills.

3

Test a copy

Submit samples first so the live form behaves predictably.

Watch the demo.

Watch the workflow once, then run a small test in your own Google file.

Frequently asked questions

Does Google Forms already have response limits?

Yes. Google Forms supports native closing by total response count or date and time. Use those controls for a simple cap or deadline. FormGuard adds per-choice quotas, scheduled opening, close messages, and owner alerts. Read the Google announcement.

Can it limit each time slot separately?

Yes. Assign a separate quota to each choice. Already-open forms and simultaneous submissions can exceed a quota; use a safety buffer and verify a fresh respondent preview. Run a two-choice quota test before launch.

Should I test on a live form first?

No. Use a copied form with tiny quotas, then apply the same setup to the real form after it passes.

Built for schools. Signed for student data privacy.

FormGuard is requested by California school districts through the CITE Privacy Services program.

LidaBan Studio has executed a California student data privacy agreement (CA-NDPA v1.5) at the request of San Bernardino City Unified School District. Other California districts can countersign the same terms through CITE Privacy Services. See FormGuard for Schools — pricing and district procurement.

FormGuard stores nothing outside your school's own Google Workspace: all settings live in Google Apps Script properties inside your tenant, and the add-on makes zero external requests. Per our signed exhibits: no AI training on student data, no advertising, no data sale. Security practices are aligned with the CIS Critical Security Controls, backed by a 72-hour incident notification commitment and an annual security review.
