How Blurline works
Set your boundaries, share the link, view the overlap. Takes a minute.
Set your boundaries
Green is ok, orange means discuss first, red is no. Missing something? Add it.
Share your link
Send your Blurline via WhatsApp, Tinder or SMS. The other person sets their own boundaries without seeing yours.
View the overlap
See where you both stand. Tap "Seen" as a read receipt. In the background, this is registered like a dashcam.
Different from anything you know
Beforehand, not in the moment
Everything happens in the chat phase, not in the bedroom.
No registration, no download
Works directly in your browser via a link. No app store, no account.
Privacy as foundation
Data is automatically deleted after 24 hours. No names, no database. Zero-knowledge.
Anonymous overlap
You only see the combined result. Who chose what is never revealed.
Dashcam, not a contract
In the background it is registered that both people have seen the boundaries. Context, not evidence.
"Seen", not "agreed"
No agree button. Just a read receipt. Boundaries can always change.
