# Client‑Side Rendering & Privacy

Blings MP5 technology renders videos on the viewer's device. Personal data is merged into the video in the browser and never leaves the user's environment.

* **Data stays local:** Personal information used to personalize the video is not sent to Blings servers during playback.
* **Reduced server risk:** Because personal data never travels to our servers for rendering, the risk of a server‑side data breach is minimized.
* **Real‑time updates:** The video reflects real‑time data from your systems without exposing that data externally.

When analytics are enabled, only anonymized events—such as a view or button click—are sent back to Blings for reporting. **These events do not include personally identifiable information**.
