Implementing Data Retention Policies for Session Replay Data

Data retention is a critical aspect to consider when using Session Replay tools. Typically, session history is retained for about 30 days. This period allows developers and analysts sufficient time to review user interactions and identify any issues. However, many platforms offer the option to extend this retention period up to 15 months for non-active sessions.

Key Considerations:

• Compliance:
• Storing session recordings must align with data privacy regulations like GDPR or CCPA.
• Ensure that sensitive user information is either anonymized or excluded from recordings.
• Storage Options:
• Decide whether you need short-term retention (e.g., 30 days) or long-term retention (up to 15 months).
• Evaluate cloud storage solutions that can handle large volumes of data securely.

By implementing robust data retention policies, you can balance the need for detailed user interaction analysis with compliance and data privacy requirements.

A Step-by-Step Guide to Implementing Session Replay in Your Web Application
