It started with my father

Get in touch with us ↗
Does Intro guarantee a caller is safe?
No. Caller information and screening are decision aids, not a guarantee. Names, business details and verification appear when available; some numbers may remain unidentified. Never share an OTP, PIN or password with a caller.
What if I'm expecting an unfamiliar caller?
Add the number to your trusted contacts, choose a more open screening mode, or turn on “Allow all calls” in Settings. You stay in control of how restrictive screening is.
How does Intro use my contacts?
With Contacts permission, Intro automatically sends contact names and phone numbers to its servers. This supports contact recognition, network connections and community caller identification. Contact-derived caller details may be shown to other Intro users. Read the full privacy policy for the data collected and your choices.
What do I need to use screening?
An Android phone, active account access, and the relevant caller ID, call-screening and display permissions. Check your subscription status in the app's Settings. Intro is designed primarily for users in India; caller and business information depends on available coverage.
