Caller context
Practical labels tell you what a number behaves like — not who you are talking to — so the decision stays yours.
Privacy-first caller ID
Know who's calling before you answer.
Useful caller context — scam, sales, delivery and more — without handing over your contacts, your call log, or which numbers you look up.
No contacts access No call log No lookup history
Spam calls keep getting smarter. Most caller ID apps ask for more than they need — your contacts, your call data. We refuse to make that trade.
What you get
Caller context, without the creepiness.
Useful labels, private lookups, and community reports — so you can decide before you pick up.
Private lookup
Check an unknown number without our servers learning which number you asked about. Privacy by cryptography, not by promise.
Community reports
Report what a number behaves like, and benefit from what others have flagged — building shared context, not a personal dossier.
Inside the app

Synced caller ID on device, private lookups for the unknowns, and community reports you can read at a glance.

Private lookup technology
Caller ID privacy you don't take on faith.
Most caller ID lookups reveal the number being checked to a company's server. MyShieldra works differently. Built on Apple's Live Caller ID Lookup, each request is protected with Oblivious HTTP, Privacy Pass anonymous authentication, and Private Information Retrieval, so your iPhone can ask for caller context without our service learning the real number or your IP address.
Not just a policy promise —
it's a cryptographic limit on what our server can learn.
1Your iPhone
turns the incoming number into an encrypted PIR query
2Apple's Oblivious HTTP OHTTP
hides the client's IP address before the lookup reaches our service
3MyShieldra PIR service PIR
finds the matching label without seeing the real number
lookup service sees neither your IP nor the real number
4Your iPhone
decodes the protected answer and shows the label
No contacts or call log are uploaded — not to us, not to Apple. Only the number being checked is looked up, and it stays protected the whole way.
