Introduction
This Privacy Policy explains how Grouper ("we," "us," "our") collects, uses, stores, and protects information when you use our platform, including the Grouper Telegram bot, the website at grouper.space, and associated services (collectively, the "Service").
By using the Service, you consent to the data practices described in this policy. If you do not agree, please do not use the Service.

- TronGrid API — TRON blockchain queries for payment verification. Processes public blockchain data.
- Infrastructure providers — Cloud hosting for servers, databases, and workers. May process IP addresses and server logs.
We do not sell, rent, or trade your personal information to third parties for marketing purposes.
Data Retention
We retain your data for as long as necessary to provide the Service:
- Account data (Telegram ID, wallet address) — Retained while your account is active
- Transaction records — Retained for a minimum of 3 years for audit and compliance
- Expired subscription data — Retained in anonymized form for analytics
- Server logs — Retained for up to 90 days
Data Security
We implement industry-standard security measures:
- Encrypted database connections (TLS/SSL)
- HMAC-signed internal API communications
- Rate limiting on public endpoints
- CSRF protection on administrative interfaces
- Secure secret management with validation at startup
While we take reasonable measures to protect your information, no method of transmission or storage is 100% secure.
Blockchain Data
TRON blockchain transactions are public and permanent. When you send or receive USDT through the Service, transaction details (wallet addresses, amounts, timestamps) are recorded on the public blockchain and cannot be deleted. This is inherent to blockchain technology and not controlled by Grouper.
Your Rights
Depending on your jurisdiction, you may have the following rights:
- Access — Request a copy of the data we hold about you
- Correction — Request correction of inaccurate data (e.g., updating your wallet address)
- Deletion — Request deletion of your account data, subject to retention obligations
- Data portability — Request your data in a structured, machine-readable format
To exercise any of these rights, contact us at hello@grouper.space. We will respond within 30 days.
Children's Privacy
The Service is not intended for individuals under 18. We do not knowingly collect personal information from children. If we become aware of such collection, we will delete it promptly.
Changes to This Policy
We may update this Privacy Policy from time to time. When we make material changes, we will update the "Last updated" date. Your continued use after changes are posted constitutes acceptance of the revised policy.
