Last updated: March 15, 2026
ZenBuild ("we," "our," or "us") operates zenbuild.io (the "Service"). This Privacy Policy explains how we collect, use, disclose, and protect your information when you use our Service.
1. Information We Collect

- PDF files: Documents you upload, create, edit, or convert using our PDF tools.
- Signatures: Electronic signatures captured through our e-signature feature, including signature images and audit trail metadata (IP address, timestamp, user agent).

Information from Third Parties
- Google OAuth: If you sign in with Google, we receive your name, email address, and profile picture from Google.

- Stripe: Payment confirmation details, subscription status, and customer identifiers.
2. How We Use Your Information
We use your information to:
- Provide, maintain, and improve the Service.
- Process payments and manage subscriptions.
- Send transactional emails (account verification, password resets, billing receipts, form submission notifications, signing requests, referral notifications).
- Enforce plan limits and usage quotas.
- Generate anonymous, aggregated analytics to improve our tools.
- Detect and prevent fraud, abuse, and security incidents.
- Respond to support requests.
We do not sell your personal information to third parties. We do not use your form submission data or PDF files to train machine learning models.
3. How We Share Your Information
We share your information only with the following categories of service providers, solely to operate the Service:
| Provider | Purpose | Data Shared |
|---|

We may also disclose your information if required by law, court order, or governmental authority, or if we believe disclosure is necessary to protect our rights, your safety, or the safety of others.
4. Data Retention
- Account data: Retained for the lifetime of your account. Deleted within 30 days of account deletion.
- Form submissions: Retained until you delete them, or until your account is deleted.

5. Data Security
We implement industry-standard security measures, including:
- HTTPS/TLS encryption for all data in transit.
- Encrypted database connections with connection pooling.
- AES-256 encryption for sensitive stored credentials (OAuth tokens).
- SHA-256 hashing for API keys (we never store raw API keys).
- Timing-safe comparison for password-protected forms.
- Rate limiting on public endpoints to prevent abuse.
- Security headers (HSTS, X-Content-Type-Options, X-Frame-Options, Referrer-Policy).
No method of transmission or storage is 100% secure. While we strive to protect your information, we cannot guarantee absolute security.
