Last Updated: 2026-01-15

1. Introduction

Welcome to ChartMkr ("we", "our", or "us"). We are committed to protecting your privacy and ensuring the security of your personal information. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our AI-powered chart generation platform at chartmkr.com (the "Service"). By using ChartMkr, you agree to the collection and use of information in accordance with this policy.

2. Information We Collect

We collect several types of information to provide and improve our Service:

  • Account Information: When you register, we collect your name, email address, and encrypted password. If you use Google OAuth login, we receive your basic profile information from Google.
  • User Content: Data you upload for chart generation, including spreadsheets, CSV files, and text data. This data is used solely to generate your charts and is stored in your account.
  • Usage Data: We automatically collect information about how you interact with our Service, including pages visited, features used, chart types generated, and time spent on the platform.
  • Payment Information: When you purchase a Pro subscription, payment is processed securely through Creem. We do not store your credit card details; only transaction records and subscription status are retained.

3. How We Use Your Information

We use the collected information for the following purposes:

  • Service Delivery: To provide AI-powered chart generation. Your data is used solely for chart generation and display, and for no other purpose.
  • Account Management: To manage your account, process payments, track your credit balance and membership benefits, and provide customer support.
  • Service Improvement: To analyze anonymous usage patterns and feature usage to improve user experience. We will never use your data to train AI models.

4. Data Security

We take data security seriously and implement multiple layers of protection. All data transmission is encrypted using TLS/SSL. Your uploaded data and generated charts are stored securely in our cloud infrastructure (Supabase) with encryption at rest. We use secure authentication mechanisms and regularly audit our security practices.

5. Third-Party Services

We use trusted third-party services to operate ChartMkr: Supabase for database and authentication, Creem for payment processing, Cloudflare R2 for file storage, and OpenAI for AI chart generation. These providers have their own privacy policies and are contractually obligated to protect your data. We do not sell your personal information to any third parties.

6. Data Retention and Deletion

We retain your personal information and user content for as long as your account is active. You can delete individual documents and charts at any time through the dashboard. If you wish to delete your entire account and all associated data, please contact us at [email protected]. Upon account deletion, we will remove your personal information within 30 days, except where retention is required by law or for legitimate business purposes.

7. Your Rights

Depending on your location, you may have the following rights: Access and obtain a copy of your data, rectify inaccurate information, request deletion of your data, object to or restrict certain processing, and data portability. For users in the European Economic Area (EEA), we comply with GDPR requirements. To exercise any of these rights, please contact us at:
