Hello, anyone knows what is expiry time of the file uploaded into ephemeral session (without registration) at Mega.nz?

Update, i got reply from the staff:
We cannot predict the expiry time, as it is determined by many factors.
To be safe, just use your account at least once a month.
Another reply:
Ephemeral sessions expire or become unavailable when the user clears the browser memory, reinstalls the operating system or otherwise loses his local browser config, or they were unused for at least a week.

So here is your answer. If you keep using the browser session you can have it running for a lot longer.

To continue a session after the browser has been closed, just go to https://mega.nz - no specific action is required.
