Keep study files private on shared devices

Know where data lives

The tools calculate in your browser. Temporary results stay in local browser storage for 24 hours. Session history remains until you delete it or clear the site's browser data. There is no account or device synchronization.

Take care on shared computers

Anyone using the same browser profile may be able to see saved sessions and results. Delete results and history when you finish. Downloaded files remain in the device's download folder even after browser data is cleared; remove them separately if needed.

Leave sensitive data out

Use generic educational examples instead of patient identifiers, passwords or confidential records. Clearing browser data may remove your only stored copy. Export what you need first and keep it in a location you control. Private-browsing mode may not retain results after the window closes.
