YouMail stands out as a 100% free spam blocker app on the Google Play Store, encrypting all data in transit for security. Its privacy policy notes potential data sharing with third parties, such as data analytics providers and payment processors. Google Play disclosures indicate it may collect unspecified information.

Truecaller provides a free spam blocker option, backed by a user base reported as over 330 million people worldwide in one source, with another citing over 50 crore users (estimates vary, reflecting its global reach). Privacy concerns arise from data handling practices common in crowd-sourced apps.

Hiya offers free spam blocking with automatic detection using a list of known phone numbers, supported by a global user base of 100 million and over 10 billion robocalls blocked. A premium tier exists at $1.99/month or $19.99/year, implying core blocking remains free. This makes it suitable for users seeking hands-off protection.

CallApp delivers free spam blocking trusted by 85 million users. It focuses on caller ID and blacklist features, with freemium upgrades possible. User feedback highlights its community-driven spam detection.

Calls Blacklist provides free spam blocking with a 4.4-star rating and a community of over 12 million users. A Pro version costs $1.99, but the base app handles blacklisting effectively. Privacy notes align with standard Android app permissions.

How to Choose the Right Free Spam Blocker for Your Needs

Weigh user trust through large bases, such as Hiya's 100 million or Truecaller's 330 million-plus estimates, for better spam detection via crowd-sourcing. Check features like automatic blocking for convenience or encryption for security. Review data sharing in privacy policies--YouMail, for example, shares with third parties including analytics providers.
