What a watch does
A watch is a request to hear about one society by email. You give an address, confirm it once, and Rentnama writes to you when the thing it promised actually happens at that society.
It is not a newsletter and not a digest of everything on Rentnama. A watch is tied to the society you were looking at when you started it.
Empty and useful societies
A watch means something different depending on what is already known about the place. At a society with no reports yet, it means: tell me when somebody reports a rent here. At a society that already has evidence, it means: tell me when those rents change.
Watching an empty society is often the more useful of the two. Most societies on Rentnama have no reports yet, and a watch is how that demand becomes visible.
Confirming and stopping
A watch is not active until you confirm it from the email Rentnama sends. An unconfirmed watch never receives a notice.
Every notice carries a link that stops the watch, and you can stop one at any time without signing in. If a message bounces or you mark it as spam, Rentnama stops sending to that address entirely.
What a watch is not
Watching a society is not a claim that you live there, and it is never treated as one. Your email address is stored encrypted, is not shown to anyone and is not attached to any rent report you have shared. Watch counts are only ever used in aggregate.
