The requirement to be "portable" doesn't override the need to be privacy-conscious. PostHog allows you to mask sensitive information directly on the , meaning sensitive data is never sent to the server in the first place. You can define CSS selectors to block specific elements or use a custom masking function to obfuscate text while still capturing user behavior on the client.

Implement automated cron jobs within your portable gateway to purge local recording files after a set period (e.g., 7 or 14 days) to prevent disk space exhaustion and minimize data liability. Conclusion

Because the data is stored as standard JSON (not a binary proprietary format), you can write a simple Python or Node script to read these files and reconstruct the session without ever touching PostHog’s server.

PostHog session replay is a powerful tool for understanding user behavior, but many teams want to know how "portable" those recordings really are. Whether you need to move data for compliance, long-term storage, or external analysis, understanding the portability of PostHog session replays is essential for a modern data stack. The Reality of Session Replay Portability
PostHog’s portability also extends to . Because it is open-source, teams with strict compliance needs can self-host the platform, ensuring session data never leaves their private cloud. Deep-Dive Features for Developers
PostHog Session Replay has traditionally been a powerful, integrated part of its all-in-one product suite . However, the shift toward —driven by its mobile SDKs and open-source nature—is changing how developers debug across platforms. The "Portable" Shift: Beyond the Browser
