Your number and privacy, in your control
- We never publish individual names on a public page or in search results.
- We never show any user who uploaded a number or a name — that data is for compliance and administration only.
- We do not publish your address book as a public list or identify you as the uploader.
- Your data stays in its own region and never leaves it.

Frequently asked questions
Is the lookup free?
Yes. Reverse lookup on the website is completely free, with no account and no app.
Why is the number owner’s name not shown on the site?
The site shows verified business names submitted by those businesses. Names from address books are not published on public web pages; app searches are available under the contact-sharing requirements.
How do I remove my number?
Open “Remove my number”, verify ownership by sending a WhatsApp message, then confirm removal. If WhatsApp is unavailable, use the email support request on the same page.
Do you sell my data or show ads?
No. No ads and no data sales. Our only revenue is the yearly subscription after the first free month.
Where is my data stored?
In one region: Riyadh. Its database, its keys, and its backups are its own, and your data does not leave the Kingdom. Numbers from Europe and the UK are refused at registration, because we do not run a region there.
