Contact us
We answer emails, not robots. Here's how to reach us depending on what you need.
General question
For any question about the app, how it works or our technical choices, email us at:
We read every message and reply as quickly as we can.
Report a bug
The app behaving unexpectedly? A number blocked by mistake, a crash, a broken display?
Please include your Android model and the app version (shown in Settings) and start the subject line with [Bug].
Number-removal request
Is your number being blocked by mistake? The removal process is explained in detail on our dedicated page:
Since our list comes from official number-range data and community reports, removal generally has to be requested directly with the relevant source.
What we can't do
We don't run an online form for now — no dedicated backend for that, and we'd rather be honest than promise a form that sits forgotten in an inbox. A direct email is simpler and more reliable.
We don't have a phone number either (the irony isn't lost on us). For everything else, email does the job, and we take the time to read.
