Privacy Policy

Last updated: April 8, 2026

What we collect

When you create an account, we collect your name, email address, and password. As you use kinako, we store the data you enter — clients, projects, invoices, proposals, notes, and files. We also collect basic usage analytics (pages visited, features used) to improve the product.

How we use your data

Your data is used to provide and improve kinako. We do not sell your personal information to third parties. We do not use your business data (clients, projects, financial information) for advertising or marketing purposes. AI features process your content to generate summaries and drafts — this data is not used to train models.

Third-party services

We use the following services to operate kinako:

  • Supabase — database, authentication, and file storage
  • Stripe — payment processing (we never see or store your full card number)
  • Vercel — hosting and deployment

Data security

All data is transmitted over HTTPS. Database access is protected by row-level security policies — you can only access your own data. File uploads are stored in private buckets with signed, time-limited access URLs.

Data deletion

You can delete your account at any time from your settings. When you delete your account, all associated data (clients, projects, files, invoices, notes) is permanently removed within 30 days.

Cookies

We use essential cookies for authentication and session management. We do not use third-party tracking cookies or run advertising scripts.

Changes to this policy

If we make significant changes to this policy, we will notify you by email. Minor clarifications may be made without notice.
