Privacy Policy — Chart & Graph Maker

Effective Date: June 23, 2025
Last Updated: October 26, 2025

Welcome to Chart Maker: Quick Tool ("App"). This Privacy Policy explains how we collect, use, disclose, and protect your information when you use our App. We are committed to safeguarding your privacy and maintaining transparency about our practices.

1. Information We Collect

We do not collect any personal information such as your name, email, phone number, or address.

However, our App collects limited, non-personal and anonymized information for performance improvement and feedback purposes:

a. Usage and Device Data (via Google Analytics)

We use Google Analytics to collect anonymous information such as:

• App usage patterns (e.g., which features are used most frequently)
  
  

• Device information (e.g., device model, OS version)
  
  

• General location data (e.g., country or region, derived from IP addresses)
  
  

This data is aggregated and cannot identify individual users.

b. Anonymous Feedback (User Suggestions)

When you use the “Suggest a Feature” or “Send Feedback” function:

• You may optionally submit text-based suggestions about features you would like to see in the App.
  
  

• These submissions are stored anonymously in our secure Firebase database.
  
  

• No personal data (name, email, etc.) is collected.
  
  

• Each device is identified only by a technical installation ID to prevent spam and duplicates.
  
  

We do not require any account, login, or registration to use this feature.

2. How We Use Information

The anonymized data collected is used solely to:

• Analyze and improve App performance and functionality
  
  

• Understand user needs and preferences
  
  

• Identify popular or requested features for future updates
  
  

• Maintain system stability and prevent abuse (rate limiting, spam prevention)
  
  

We do not use this data for advertising or profiling.

3. Sharing Information

We only share anonymized, non-personal data with trusted service providers as follows:

• Google Analytics (by Google LLC) — for aggregated usage analysis
  
  

• Firebase (by Google LLC) — for storing anonymous feedback safely
  
  

All partners process data in accordance with their own privacy policies:

• Google Privacy Policy
  
  

We do not share or sell any user information to third parties for marketing or advertising purposes.

4. Data Storage and Security

• All data is securely transmitted and stored using industry-standard encryption.
  
  

• Feedback text and installation identifiers are stored in Firebase Firestore, protected by strict security rules.
  
  

• We take reasonable measures to protect your information against unauthorized access, alteration, or disclosure.
  
  

5. Data Retention and Deletion

• Anonymous feedback is typically retained for up to 180 days, then permanently deleted.
  
  

• Users can request deletion of their feedback by providing their App Installation ID via email at abzpro.apps@gmail.com.
  
  

• We will remove the associated data from our system within a reasonable timeframe.
  
  

6. Children’s Privacy

Our App can be used by users of all ages but is not directed toward children under 13.
We do not knowingly collect any personal data from children.
If we discover that a child under 13 has submitted any identifiable information, we will promptly delete it.

7. Changes to This Policy

We may update this Privacy Policy periodically to reflect new features or legal requirements.
Any updates will be posted in this document and, where appropriate, in the App itself.
Please review this page occasionally to stay informed.
