Questions
WhatsApp needs the full international number: country code + mobile number, without the leading 0 — for India, 91 followed by the 10-digit mobile. The cleaner does this for every number in your list.
Yes. “98765 43210”, “+91-98765-43210” and “09876543210” are recognised as the same number, and only the first one is kept.
It's too short or too long, looks like a landline (Indian mobiles start with 6–9), or is a placeholder like 9999999999. Each one shows the reason.
Yes. Export your contacts as a .vcf file from your phone or Google Contacts and upload it — names and numbers are read automatically.
No. Cleaning happens entirely in your browser; your list never reaches our servers.
