Barra: bloqueia golpe e spam

Barra is your family's watchdog against scam calls, spam, and abusive telemarketing. It recognizes the robot and blocks the call before the first ring—the decision happens on your phone, in milliseconds, even without internet.

Tired of unwanted calls from unknown numbers? Robots change numbers all the time, but repeat the same numbering range. Barra recognizes this pattern and filters these calls automatically, without you needing to register each number individually.

HOW IT PROTECTS
• Blocking on the device itself: the decision happens on your phone, in milliseconds, even without internet.

• Robot range detection: scammers change numbers all the time; Barra recognizes the pattern of the range, not just the exact number.

• Collective reporting database: numbers blocked as scams help protect everyone—we only send a scrambled code, never your contact list.

• You choose the level of protection: everyone with scam filtering, only those in your contact list, or only the family circle.

MADE TO PROTECT THOSE YOU LOVE
• Simple Mode: large screen and clear buttons for parents and grandparents to use without help.

• Family Circle: in the most protected mode, only the people you choose can call.

• Install on your parents' cell phone and set up in minutes.

AND IT EVEN ORGANIZES THE CONTACT LIST
• Finds duplicate contacts and merges them into one, with automatic backup — nothing is deleted without your approval.

TRUE PRIVACY
• No ads and no data sales.

• Your contact list never leaves your phone.

• Identified Brazilian company, with public CNPJ and clear privacy policy: barra.attempo.net/privacidade.html

HOW MUCH DOES IT COST?
• 15-day free trial with all features, no credit card required.

• After the trial, scam blocking continues to work for free.

• Complete plan for R$ 9.90/month for up to 3 devices.

HOW IT WORKS INSIDE
Barra uses the official Android call screening role. When you open the app for the first time, Android asks for your confirmation to give this role to Barra — that's how it manages to block the call before the phone rings.
