Privacy Policy

Last Updated: April 21, 2026

Overview

Algo2Vis (hereinafter referred to as "we," "us," or "our") operates the https://algo2vis.com website and related services. This Privacy Policy explains how we collect, use, store, and protect your information when you use our data structure and algorithm visualization services. We are committed to handling your data with care and transparency.

Data We Collect

We collect the following categories of information:

1. Code Files and Content: When you upload or write code using the online editor to generate visualization animations, we receive and process your code files. These files are used to execute algorithms, generate visualization results, and may be stored based on your settings.

2. Account Information: When you register for an account, we collect your email address through our third-party authentication service provider, Clerk. If you choose to log in via a social account, Clerk provides us with the basic information you authorize, such as username and profile picture.

3. Usage Data: We collect data related to your interaction with the service, such as the types of algorithms you access, the number of visualizations generated, session duration, and feature usage frequency. This helps us improve service performance and user experience.

4. Billing Information: All payment processing is handled by Creem. We do not directly collect or store your full payment credentials (e.g., credit card numbers). We only receive transaction status, subscription level, and billing identifiers related to your account from Creem.

How We Use Your Data

We use the collected data for the following purposes:

To execute your uploaded code and generate corresponding data structure and algorithm visualization animations.

To manage your account, verify your identity, and enforce subscription-related access restrictions.

To send necessary service notifications (e.g., account verification, subscription status updates).

To analyze aggregated usage data to monitor service stability, diagnose issues, and improve product functionality.

To fulfill legal obligations.

We commit: We do not sell your personal data to any third party, nor do we use your uploaded proprietary code to train machine learning models for ourselves or third parties.

Data Retention

Code Files: Code you actively upload for one-time visualization will be automatically deleted within a reasonable time after processing. Code you choose to save in "My Code" or similar history will be stored until you actively delete it or close your account.

Account Information: We retain your account information as long as your account is active. After you request account deletion, we will delete your personal data within 30 days, unless required by law to retain it for a longer period.

Usage Data: Aggregated, non-personally identifiable usage data may be retained permanently for service analysis.

We rely on the following third-party service providers to operate Algo2Vis:

Clerk: Used for user authentication and account management. When you use Clerk for login, their privacy policy governs their processing of your data.

Creem: Acts as our payment processor, handling all subscription and payment transactions. Your payment information is subject to Creem's privacy policy.

Alibaba Cloud: Serves as our cloud computing service provider for deploying servers, databases, and storing files. Your data (e.g., code, account information) is stored on their platform.

Cookies and Tracking Technologies
