Privacy Policy

Last updated: August 26, 2026

1. Introduction This Privacy Policy describes how [Your Center Name / App Developer Name] ("we", "us", or "our") manages information in our Abacus Practice Application (the "App"). The App is designed to help students practice abacus skills and track their progress.

2. Information We Collect To manage student profiles and track practice sessions, we collect the following limited information:

• Account & Login Credentials: A user-provided mobile phone number and a 4-digit PIN. This combination is used solely as an account identifier for secure login. No SMS OTP or external phone verification is conducted.

• Student Practice Data: Practice performance metrics, including session timestamps, scores, speeds, level progression, and exercise history.

• Technical & Device Information: Basic non-personal technical data (such as device model and OS version) required to run the application smoothly.

3. How We Use Information We use the collected information exclusively to:

• Authenticate students into their practice accounts using their mobile number and PIN.

• Store and display student practice history, speed, and accuracy scores.

• Allow instructors and students to monitor learning progress over time.

4. Data Storage and Third-Party Services

• Supabase Cloud Database: We use Supabase (a secure backend platform) to host our database, handle user authentication, and store practice records. Data is stored securely using industry-standard database protection measures (including Row Level Security).

• We do not sell, rent, or share student phone numbers, PINs, or performance data with third-party advertisers or data brokers.

5. Application Permissions The App requires an active Internet Access permission to synchronize login information and practice data with our database. No unnecessary device permissions (such as Contacts, Location, or Camera) are requested or used.

6. Children’s Privacy Because this App is intended for educational practice by students (including young learners), we minimize data collection to the absolute necessary minimum (mobile number, 4-digit PIN, and practice scores). We do not collect names, home addresses, or location data. Parents or guardians may contact us at any time to request the deletion of a student's account and practice records.

7. Data Security We implement secure database access policies to protect student accounts. However, users are responsible for keeping their 4-digit PIN confidential.
