Cornr is built around one promise: your neighbours know which block you are on, and nothing more. Here is exactly what that means.
Cornr never stores your exact location. Your phone works out which hexagon of the map you're standing in and sends only that hexagon's ID. Your coordinates never leave your device. There is no column in our database that could hold your address, because we deliberately removed it.
Your neighbors see what you write and the fact that you're active. Nobody outside your cornr sees your talk at all, because a cornr cannot be read from outside.
We use Supabase to store data and Apple Push Notification service to deliver notifications. That is the complete list. We don't sell your data, share it with advertisers, or use it to train anything.
Open Cornr and go to You → Settings → Delete account. That removes your profile, your posts, your messages, and the account itself. It happens immediately, it cannot be undone, and you do not have to email anyone to ask.
Cornr is not for anyone under 17, and we don't knowingly collect anything from children. If you believe a child has an account, write to us and we'll remove it.
You can see everything we hold about you inside the app, correct it in Settings, and delete all of it at any time. If you're somewhere with additional data rights and need something we haven't covered, use our contact form.
If we change anything meaningful here we'll tell you in the app before it takes effect, not quietly, and not by updating a date on a page nobody reads.
We answer every message, and there is no wrong one to send.
