Privacy Policy

Last updated: February 25, 2026

This Privacy Policy describes how BuilderGPT ("we", "our", or "us") collects, uses, and protects your information when you use our mobile application ("App").

By using the App, you agree to the practices described in this Privacy Policy. If you do not agree, please do not use the App.

1. Information We Collect

We aim to collect only the minimum amount of information necessary to operate and improve the App. Depending on how you use BuilderGPT, we may collect and process the following types of data:

1.1 Device and Technical Information

• Device model and operating system version;
• Language and region settings on your device;
• App version and basic technical configuration.

1.2 Usage Data

• Screens you view and buttons you tap within the App;
• Session length and frequency of use;
• Events related to features (for example, when you start an AI generation, open guides, or complete certain actions);
• Crash reports and error logs.

1.3 Subscription and Purchase Information

• Subscription status (for example, active / inactive / plan type);
• Token balances and Token purchase history;
• Identifiers related to your app store purchases (for example, anonymous transaction IDs or product identifiers) as provided by the app store or our subscription provider.

1.4 AI Inputs (Prompts) and Uploaded Content

When you use AI features, you may provide text prompts and/or other inputs. In some versions of the App, you may also upload files for processing (if available).

• Prompts or text instructions you enter for AI generation;
• Any reference images you optionally attach to guide the AI generation.

1.5 Network Information

• Approximate IP address (used for security, basic analytics, and to operate the service).

1.6 What We Do Not Collect by Default

• We do not collect your real name, email address, or contacts through the App interface, unless you voluntarily contact us by email.
• We do not collect your precise GPS location.
• We do not perform facial recognition or extract biometric identifiers from your uploads.

2. How We Use the Information

We use the collected data to:

• Provide and maintain the App;
• Operate AI features and generate content based on your inputs;
• Manage subscriptions, Token balances, and in-app purchases;
• Display your Token balance, subscription status, and history inside the App;
• Monitor and improve performance, stability, and user experience;
• Detect, prevent, and address technical issues, abuse, or misuse;
• Generate anonymous statistics and analytics to understand how the App is used.

3. AI-Powered Features and Third-Party AI Services

3.1 What Data Is Sent to a Third-Party AI Service

The App includes AI-powered features that allow you to generate Minecraft structures from text descriptions. To provide these features, the following data may be sent to a third-party AI service:

• Text prompts — the description of the build you enter (for example, "a medieval castle with towers");
• Reference images — if you optionally attach an image to guide the generation.

No other personal data (such as your name, email, device identifier, IP address, or payment information) is sent to the third-party AI service.

3.2 Who the Data Is Sent To

Your text prompts and optional reference images are sent to OpenAI, L.L.C. ("OpenAI") via their API for processing. OpenAI acts as a data processor on our behalf solely to generate the requested content.

You can review OpenAI's privacy practices at: https://openai.com/policies/privacy-policy

3.3 How the Data Is Used by the AI Service

• Your prompts and images are used solely to generate the content you requested.
• Under OpenAI's API data usage policy, data submitted through the API is not used to train or improve OpenAI's models.
• OpenAI may retain API inputs for up to 30 days for abuse and misuse monitoring purposes, after which they are deleted. Zero-day retention may apply depending on the endpoint used.
• Your data is not sold to any third party and is not used for advertising.

3.4 Your Consent

Before any data is sent to the third-party AI service for the first time, the App will ask for your explicit consent. You may choose to decline, in which case your data will not be sent and the AI generation features will not be available. You only need to provide consent once; it will be remembered for future use.

3.5 Data Security in Transit

All data transmitted between the App, our servers, and OpenAI's API is encrypted using HTTPS/TLS. OpenAI maintains industry-standard security measures to protect data during processing.

3.6 Onboarding and Promotional Examples

The App may display example prompts, example results, previews, or demonstration content in onboarding screens, paywalls, tutorials, or marketing materials. These examples are for illustrative purposes only and do not reflect guaranteed results.

Outputs from generative AI may vary significantly based on prompt wording, context, system parameters, model updates, safety filters, and service load. As a result, the quality, style, detail level, and usefulness of generated outputs may differ from any examples shown.

3.7 Storage of AI Inputs and Outputs

• We may temporarily store prompts and associated technical metadata on our secure servers to process requests, prevent abuse, troubleshoot issues, and improve reliability.
• Generated outputs ("Generated Content") may be stored so you can access your history and reuse results inside the App (where the feature is available).
• While we aim to store data reliably, prompts, history, or Generated Content may be deleted or lost due to technical issues, maintenance, server problems, or data corruption. We do not guarantee permanent availability of any Generated Content, to the maximum extent permitted by law.

3.8 No Biometric Identification or Face Recognition

We do not use uploads or Generated Content to perform facial recognition, identify individuals, or build biometric profiles.

3.9 No Use for Training Separate Models Without Your Consent

We do not use your prompts, uploads, or Generated Content to train or create separate general-purpose AI models beyond what is necessary to provide BuilderGPT's AI features, unless we clearly inform you and obtain your explicit consent where required.

3.10 Your Responsibility for Content

You are responsible for the prompts and any content you upload, as well as for how you use Generated Content. You must ensure that:

• you have the rights to use any content you upload;
• your inputs and use of Generated Content do not violate laws or third-party rights;
• you comply with all relevant policies (for example, Minecraft-related policies by Mojang/Microsoft).

4. Legal Bases for Processing (Where Applicable)

Depending on your location (for example, if you are in the European Economic Area or the UK), we process personal data under one or more legal bases:

• Performance of a contract: to provide access to the App, tokens, subscriptions, and AI features;
• Legitimate interests: to improve the App, prevent abuse, and maintain security;
• Consent: where required, for specific uses such as sending data to third-party AI services for generation;
• Compliance with legal obligations: where required by law.

5. Third-Party Services

We may use trusted third-party services to operate the App, such as:

• OpenAI — to power AI-based content generation features (see Section 3 for details on what data is shared);
• RevenueCat or similar providers, to manage subscriptions and in-app purchases;
• App store providers (Apple App Store, Google Play) for billing and distribution;
• Analytics and crash reporting services used in the Expo / React Native ecosystem;
• Hosting and infrastructure providers for servers and databases.

These third parties may process data on our behalf and are obligated to protect it under their own policies and applicable law. We require that any third party with access to user data provides the same or equivalent level of data protection as described in this Privacy Policy.

6. Data Retention

We retain information for as long as reasonably necessary to operate the App and fulfill the purposes described in this Policy, or as required by law.

• Device and usage data: retained as needed for analytics and troubleshooting, then deleted or anonymized.
• Subscription and purchase records: retained as required for accounting, tax, and legal obligations.
• AI inputs and uploaded content (if applicable): may be stored temporarily for processing, security, and troubleshooting.
• Generated Content: may be stored to support your history, but may be deleted at any time due to technical issues or maintenance.
• AI consent records: retained as long as your account exists to avoid repeated consent requests.

7. Children's Privacy

The App is not intended for children under 13. We do not knowingly collect personal data from children under 13. If you believe that a child under 13 has provided us with personal information, please contact us so we can delete it.

8. International Data Transfers

We may store and process information on servers located in different countries. In particular, data sent to OpenAI for AI processing may be processed on servers located in the United States. Data protection laws may differ from those in your country. We take reasonable steps to protect information in accordance with this Policy and applicable law.

9. Security

We use reasonable technical and organizational measures to protect data from accidental loss, misuse, and unauthorized access, such as:

• secure servers and restricted access controls;
• encryption in transit (HTTPS/TLS) for all data transfers, including transfers to third-party AI services;
• data minimization and access limitation.

However, no method of transmission or storage is 100% secure and we cannot guarantee absolute security.

10. Your Rights

Depending on your location, you may have rights regarding your personal data, including access, correction, deletion, restriction, objection, and data portability (where applicable).

To exercise your rights, contact us at: gohelpapps0@gmail.com. We may ask you to verify your identity before fulfilling your request.

11. Cookies and Similar Technologies

The mobile App typically does not use "cookies" like websites, but may use similar technologies (such as local storage or identifiers) to remember preferences, operate subscriptions/tokens, and support analytics or reliability.

12. Do Not Track and Similar Signals

Some browsers provide "Do Not Track" signals. There is no universally accepted standard for responding to them, and our App does not respond to DNT signals.

13. Changes to This Privacy Policy

We may update this Policy from time to time. If we make material changes, we will notify you within the App, via the app store listing, or by other reasonable means. Continued use after changes become effective constitutes acceptance.
