Yes! However, we perform housekeeping to ensure we don’t run out of space. Typically, data that hasn't been accessed for 7 days will be deleted. More information can be found

The Retention Period

Your data on justseed.it will be stored indefinitely provided it is actively seeding. However it is important to understand the retention period for inactive data is a standard 7 (seven) days. This means any data that hasn't actually seeded or been direct downloaded for more than 7 days will be deleted.

It is important to note that the retention period varies. Under heavy usage the retention period for a server may drop below 7 days. The system will drop the retention period to as low as necessary in order to allow new content to be added.
