Memory per user
Memory per user means each person has their own memory inside your app, and a call reads only the memory of the user it names.
How it works
Your code names the user in every call with the X-Harny-User header. Recall returns what that person's memory holds, and nothing from anyone else's.
When to use a separate app
Use a separate app for each separate authorization domain, such as two customers who must never share anything.
Do my users need a Harny account?
No. They are people your app already knows. Your calls name them.
Go on. Get Harny.
The first 500 monthly-active end users are free for good. Create an app key and make your first call in minutes.
