Overview
Zeto Sign lets you collect legally binding eSignatures directly from your Google Forms™ workflow. If you use Google Forms™ for consent forms, waivers, HR onboarding, approvals, or client agreements, Zeto Sign closes the gap that Google Forms™ doesn't handle natively: a real, secure eSignature attached to every single submission.

Instead of asking clients to print, scan, or use complicated third-party PDF software, respondents sign directly from any phone, tablet, or desktop using a finger, mouse, or stylus. When they hit submit, Zeto Sign natively pushes the signature data straight into your connected Google Sheets™ document. No app switching. No printing. No manual data entry.

Security, Privacy, and Compliance
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Zeto Sign was built with enterprise-grade privacy in mind. While older legacy add-ons require invasive permissions to read your entire Google Drive™ or all of your Google Sheets™, Zeto Sign's modern architecture completely bypasses this. We only ask for the minimum scopes needed to sync your form questions. Your data remains yours, and we never sell, share, or use your workspace data for AI model training.
