Callro vs. TrueCaller
TrueCaller maintains a massive crowdsourced database of phone numbers. The catch: every user's contacts are uploaded to build that database. Your privacy is the product.
Quick Answer
Truecaller requires users to upload their contacts to build its crowdsourced directory. Callro provides 26-layer on-device spam blocking without accessing your address book, ensuring your private data never leaves your phone.

The Bottom Line
TrueCaller's entire business model depends on harvesting your contacts to build their database. When you install TrueCaller, everyone in your address book becomes part of their system — without their consent. Callro never touches your contacts.
