Privacy Policy

Grindx AI (“we”, “us”, “our”) provides an AI-powered study assistant that helps users upload study materials, generate summaries, ask questions, create practice questions, and use mock tests and text-to-speech features.

This Privacy Policy explains what information we collect, how we use it, when we share it, how long we keep it, and what choices users have.

1. Information We Collect

We may collect the following categories of information:

A. Account Information

When you create an account or sign in, we may collect:

• Stripe customer ID
• Stripe subscription ID
• Subscription status
• Trial and plan end dates

E. Minimal Anti-Abuse Retention

If you delete your account after using a free trial or paid subscription flow, we may retain a minimal record of your email address solely to help prevent repeated free-trial abuse and protect the integrity of our billing system. We do not retain deleted study content for this purpose.

• Create and manage user accounts

• Enforce plan limits and prevent misuse
• Maintain app security, reliability, and performance
• Comply with legal obligations

3. How We Process Study Content

Study materials and chat content you submit are processed to deliver app functionality, including:

• Document analysis
• AI-generated answers
• OCR and image-based text extraction
• Language translation

This processing may involve trusted third-party service providers that help us deliver these features.

4. Third-Party Services

We may use third-party providers to operate Grindx AI, including services for:

• Authentication and database hosting
• Subscription and payment processing
• AI and language model processing

6. Data Retention

We retain personal information only for as long as reasonably necessary for the purposes described in this Privacy Policy.

Account and Study Data

Documents, chat history, profile data, and related app data are kept while your account remains active, unless deleted earlier by you or us.

Deleted Documents and Chat

If you delete a document or clear chat history, the associated stored data is removed from our app systems in line with our deletion workflow.

Deleted Accounts

If you delete your account, your profile, documents, chat history, and related study data are removed from our application systems, subject to technical, legal, fraud-prevention, and billing-integrity needs.

Limited Retained Identifier

If applicable, we may retain a minimal email record solely to prevent repeated trial abuse and support billing integrity. We do not keep deleted study materials for that purpose.

9. Children’s Privacy

Grindx AI is intended for general educational use. If you are a parent or guardian and believe a child has provided personal information in violation of applicable law, contact us so we can review and take appropriate action.

10. International Data Processing

Your information may be processed in countries other than your own, depending on where our service providers operate. Where required, we take reasonable steps to protect personal information in line with applicable law.

11. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. When we do, we will update the effective date above. Continued use of the app after an update means the updated Privacy Policy applies, to the extent permitted by law.
