Google app engine entity gets deleted agter 7 days

I'm using Google cloud for back end of my Android app.
I save an entity:


But after 7 days the entity gets deleted from the datastore.
I want to keep them forever, or at least for much longer period.


It is possible that you reuse an entity's id and therefor overwrite the existing entity yourself every 7 days (well or a web crawler does).

Take a look at the datastore in the developers console. You should see only a few writes to your entity, but if i'm right you'll see something like 5 writes and more (the actual write count depends on the amount of indexes defined in your entity).

To make sure this doesn't happen you can simply set the @Id Long id property of your greeting to null before you call save() so you'll get an auto generated id.
