Call Blocker: Anti Spam ("the App") is developed by Caja Negra Dev. This Privacy Policy explains what information is stored, how it is used, and how it is protected.
2. Information Stored by the App
The App stores the following information locally on your device:
Phone numbers you add to the Block List and Allow List.
History of calls blocked by the App.
App preferences and settings (language, schedules, blocking options).
This information never leaves your device unless you enable Google Drive backup.
If you choose to report a call as spam, the following information is sent to our servers:
Phone number: The reported phone number is normalized to the international E.164 format (for example, +34612345678) and sent to our servers to help identify and block spam numbers for the community.
Hashed device identifier: A unique identifier generated from your device that allows us to prevent duplicate reports. It cannot be used to personally identify you.
Spam category: The category you selected, such as Telemarketing, Fraud, Robocall, Harassment, or Other.
Reporter country: The mobile operator or SIM country code (for example, "ES") used for regional statistics.
Your personal phone number is never transmitted from your device.
If you enable backup, the App stores your Block List and Allow List in your own Google Drive, inside a private folder accessible only by you. We do not have access to these files.
Fingerprint and facial recognition authentication are handled entirely by Android on your device. The App does not access, collect, or store any biometric data.
The App may request the following permissions:
Phone: Detect incoming and missed calls.
Call Logs: Determine whether a call was incoming or outgoing.
Contacts: Ensure your saved contacts are never blocked.
Notifications: Notify you when a call is blocked or when an unknown caller is detected.
Call Screening: Block calls in real time according to your configured rules.
Users of the free version may see advertisements provided by Google. Google may collect device information to display relevant ads.
Premium users do not see advertisements.
