01
The recipient always decides
Nothing is shown until they choose to open it. They see who is asking and how much was paid, never the message itself, before they decide.
Safety
The recipient holds every switch.
Kildr only works if the person on the other end stays in control. They do: decline a request, block a sender for good, or opt out of Kildr entirely.

Recipient control
Five ways the other person stays in charge.
02
A request, not a campaign
Each request carries one message and expires after 7 days if it isn't opened. A sender can pay to send again, but they can never make it arrive: once you block them, later requests are held silently and you are not notified at all.
03
Decline, block, or opt out
A recipient can decline a single request, block one specific sender so nothing they send afterwards reaches the phone, or opt out of Kildr entirely so no request can be delivered to their number. Anything a blocked sender paid for is only ever shown if the recipient chooses to unblock them, and then it arrives slowly, one message at a time.
04
Reporting
Every opened message can be reported. Abusive senders lose access to Kildr. Paying is not a shield.
05
What payment does and doesn't buy
Payment buys the ability to submit one request through Kildr. It never buys consent, a reading, a reply, or forgiveness.
See it work
A block is the last word.
Blocking a sender stops every future request from reaching your phone. They are never told. Anything they pay for afterwards is held silently, and only ever surfaces if you decide to unblock them.
Try the demo. Block the sender, then unblock, to see exactly what a recipient controls.
Wondering where the line is? Is it illegal to contact someone who blocked you?
Incoming request
DemoAlex wants to send you a message.
Amount paid: $120
The sender paid this amount to Kildr for the request. You do not receive it, and you still decide what happens next.
For illustration only. Opening a real Kildr message is free for the recipient. Nothing in this demo is sent to anyone.
For senders
Reaching out should not expose you either.
Your number is never shared
The recipient never sees your phone number. It is used only to verify you and to give you a private status link.
Anonymity is your choice
Choose to show your name or stay anonymous. If you stay anonymous, the recipient only sees that someone wants to send one message.
The message stays sealed
They won't see what you've written unless they choose to open the message. It is stored encrypted and never travels inside the SMS.
