Privacy Policy

This Privacy Policy explains how the Chessvision.ai Telegram Bot ("Bot") collects, uses, stores, and shares information from its users ("Users").

This policy applies to the Chessvision.ai Telegram Bot available at https://t.me/ChessvisionAiBot.

We respect your privacy and are committed to protecting the personal information you share with us. Details of our data practices are described below.

How We Collect, Use, Store, and Share Data

Library Integration

The Bot allows Users to save scanned chess diagrams to their Chessvision.ai Library ("Library") accounts. To enable this feature, a User must link their Telegram account to their Library account. This connection is one-directional - you can use the Bot to send diagrams to your Library, but the Library does not have access to your Telegram account or messages.

When you connect your accounts, your Telegram user ID and username are shared with the App. Saved diagrams are stored in FEN format along with limited metadata (such as the diagram name, creation time, and last opened time).

Usage Data

We collect anonymized usage data to help us understand how the Bot is used and to improve its functionality. This may include information such as feature usage frequency or interaction patterns. To analyze this data, we use third-party analytics tools, including Google Analytics, Segment, and Amplitude.

Data Security and Retention

We use appropriate technical and organizational measures to protect your information from unauthorized access, alteration, disclosure, or destruction. We retain collected data only for as long as necessary to fulfill the purposes described in this policy or as required by applicable law.

Changes to This Privacy Policy

We may update this Privacy Policy from time to time. When we do, we will revise the “Last modified” date at the top of this page. We encourage Users to review this page periodically to stay informed about any changes. Continued use of the Bot after such updates constitutes your acknowledgment and acceptance of the revised policy.

Your Acceptance of These Terms

By using the Bot, you agree to this Privacy Policy. If you do not agree with its terms, please discontinue use of the Bot.
