Privacy Policy

How we collect, use, and protect your data.

Last updated: March 2026Version 1.0

Who we are

Closio AI is an AI-powered proposal generation tool operated by Abdullah Khan. Our registered address and contact details are available at closioai.com/contact. For all privacy-related enquiries, contact us at privacy@closioai.com.

What data we collect

Account data

When you create an account we collect your full name, email address, company name, and job title. This data is required to provide the service.

Proposal data

All proposals you create, including client names, project details, and generated content, are stored securely in our database. This data belongs to you and can be exported or deleted at any time.

Usage data

We collect anonymous usage data including pages visited, features used, and session duration. This helps us improve the product. We use PostHog for analytics — data is anonymised and not sold to third parties.

Payment data

We do not store your payment card details. All payments are processed by Polar.sh who act as Merchant of Record. Polar's privacy policy applies to payment data.

Communications

If you contact us by email, we store that correspondence. If you subscribe to our email list via Loops.so, your email and name are stored in Loops.

How we use your data

  • To provide and improve the Closio AI service
  • To authenticate your account and keep it secure
  • To send transactional emails — proposal notifications, payment confirmations, team invites
  • To send product updates if you have opted in
  • To respond to support requests
  • To detect and prevent fraud or abuse

Who we share data with

We do not sell your data. We share data only with the third-party services required to operate Closio AI.

Data storage and security

Your data is stored in Supabase's hosted PostgreSQL database with Row Level Security (RLS) enabled — meaning each user can only access their own data. Data is encrypted at rest and in transit using TLS 1.3. Signature images and signed PDFs are stored in Supabase Storage with encrypted buckets.
