Why you collect it.
How you store it (security measures).
How long you retain it.
Whether you share it with any third parties (e.g., payment processors, delivery services) and why.
How users can request to access, correct, or delete their data.
Link to Policy: Include a link to your privacy policy in your bot’s @BotFather description.
Implement Robust Security Measures for Stored Data:
If your bot needs to store phone numbers (or any other personal data), ensure it’s done securely:
Encryption:
Encryption at Rest: Store all sensitive data, including phone numbers, in an encrypted format in your database. Use industry-standard encryption algorithms.
Encryption in Transit: Ensure all communication between your bot’s server, database, and any third-party APIs uses secure protocols (e.g., HTTPS/SSL/TLS).
Access Control:
Principle of Least Privilege: Grant telegram number database database and server access only to authorized personnel who absolutely need it, and limit their permissions to the minimum necessary.
Multi-Factor Authentication (MFA): Implement MFA for all administrative access to your bot’s backend systems and databases.
Data Minimization & Retention:
Only store data for as long as it is the importance of email address data protection necessary for the stated purpose. Implement data retention policies to automatically delete data after a certain period if it’s no longer needed.
Regular Security Audits: Periodically book your list audit your bot’s code, infrastructure, and data storage for vulnerabilities. Stay updated on common security threats (e.g., OWASP Top 10) and best practices.
