Privacy Policy — BlockSim

Effective Date: 2025-12-12

BlockSim ("we", "us", or "the App") provides an AI-assisted crypto strategy simulation platform with leaderboards and AI chat for generating custom strategies. This Privacy Policy explains how we use the two permissions requested by the App (Network access and Notifications) and how we handle data.

1. App Permissions (Network & Notifications)

Network access is required for:

Notification permission is used to:

2. Personal Data

By default, BlockSim is designed to minimize personal data collection. We do not collect or store personal identity data (name, email, phone number, photos, biometric data) unless you explicitly provide such information through a feature that asks for it. Core simulation and AI features can be used without creating an account.

3. What We May Collect

When you use network-enabled features, we may process the following non-personal information:

If you choose to use the AI chat that uses external AI services, the text of your prompts and the generated responses may be transmitted to the AI provider as described when you enable that feature. You will be informed and required to opt in where applicable.

4. Local Processing

Whenever possible, simulations and strategy calculations are performed locally on your device. Local data (user settings, local simulation histories) remains on your device unless you explicitly choose to share or publish strategy results to the public leaderboard.

5. Leaderboards and Public Data

If you publish performance to public leaderboards, the following information may be shown publicly:

Leaderboard entries do not include personal contact details. You may request removal of a leaderboard entry via the contact information below.

6. Third-Party Services

BlockSim may use third-party services for market data, AI model hosting, and crash/analytics reporting. These services may process data as described in their own privacy policies. When an external AI provider is used, any prompts or inputs you submit to the AI will be transmitted to that provider only with your consent.

Facebook SDK. BlockSim integrates the Facebook SDK for analytics and attribution. The Facebook SDK may collect device identifiers, app events, and crash data as described in Facebook's Data Policy. We do not receive your Facebook account password or direct social graph data from this SDK.

7. Data Security

We take reasonable measures to protect data transmitted to our servers, including transport layer encryption. We do not store personal identity information by default. Local data is stored on your device and can be cleared from the App settings.

8. Children

BlockSim is not intended for children under 13. We do not knowingly collect personal information from children under 13.

9. Your Rights & Controls

10. Changes to this Policy

We may update this policy from time to time. The revised policy will include a new effective date. Continued use of the App after changes indicates acceptance of the updated policy.
