Privacy Policy

1. Information We Collect

When you create an account, we collect your email address and name (provided via Google OAuth or email sign-in). When you use Wintura to generate proposals, we collect the client briefs, proposal content, and agency profile information you provide.

We also automatically collect usage data including pages visited, features used, and proposal view tracking (anonymized IP hashes for deduplication, not raw IP addresses).

2. How We Use Your Information

We use your information to:

• Provide and improve the Wintura service
• Generate AI-powered proposals based on your client briefs
• Send transactional emails (magic link login, proposal delivery)
• Process payments through Stripe
• Track proposal views to help you understand client engagement

3. Data Storage & Security

Your data is stored in a secure PostgreSQL database hosted on Neon (AWS us-east-2). All connections are encrypted in transit via TLS. We do not store raw IP addresses — only salted hashes for view deduplication.

Payment information is handled entirely by Stripe and never touches our servers.

4. Third-Party Services

We use the following third-party services:

• Anthropic (Claude AI) — to generate proposal content from your briefs
• Stripe — to process subscription payments
• Resend — to send transactional emails
• Vercel — to host the application
• Neon — to host the database
• Google — for OAuth authentication

Each service has its own privacy policy. We encourage you to review them.

5. AI-Generated Content

Client briefs you submit are sent to Anthropic's Claude API to generate proposals. Anthropic does not use API inputs for training. Your briefs and generated proposals are not shared with other users or used to improve AI models.

6. Data Retention

Your account data and proposals are retained as long as your account is active. You can delete individual proposals at any time. To delete your entire account and all associated data, contact us at the email below.

7. Cookies

We use essential cookies only — session cookies for authentication. We do not use tracking cookies or third-party analytics cookies.

8. Your Rights

You have the right to access, correct, or delete your personal data. You can export your proposals at any time via PDF export. To exercise any data rights, contact us at privacy@wintura.ai.

9. Changes

We may update this privacy policy from time to time. We will notify you of material changes via email or an in-app notification.
