SPAM-JAMR™ — Advanced Call Protection
Effective date: February 1, 2026 | CYBERINE LLC, Bunker Hill, West Virginia, USA
The short version: SPAM-JAMR analyzes calls entirely on your device. We do not collect, transmit, sell, or share your phone numbers, contacts, call history, location, or any other personal information. The app has no accounts, no analytics, no advertising, and no tracking. Its only network activity is downloading public threat data — never uploading anything about you.
1. Who We Are
SPAM-JAMR™ is a call screening application developed and published by CYBERINE LLC ("we," "us," "our"), a West Virginia limited liability company. This policy describes how the SPAM-JAMR Android application handles information.
2. Information We Do Not Collect
SPAM-JAMR is designed so that your personal information never leaves your device. We do not collect, receive, store on our servers, or have access to:
Your phone number or the phone numbers of people who call you
Your contact list or any contact details
Call recordings, call logs, voicemails, or call content of any kind
Your precise or approximate location
Device identifiers, advertising identifiers, or usage analytics
Any personally identifying information
The app requires no account, registration, sign-in, or email address. We operate no user database because there is nothing to put in one.
3. How Call Analysis Works
When a call arrives, SPAM-JAMR evaluates it on your device using a multi-factor risk model that considers the caller's area code risk profile, on-device machine learning, observed call behavior patterns, and public regulatory complaint data. All of this computation, and all of the data it produces, stays on your phone. Risk scores, blocked-call records, analysis history, your spam list, and your whitelist are stored in a local database on your device only.
4. Permissions and Why We Request Them
The following is the complete list of Android permissions the App declares, organized by how Android grants them. All permissions are used exclusively on-device; none of them results in personal data being transmitted anywhere.
Android only prompts you for some of these. Others are granted through system settings screens, and some are granted automatically at install with no prompt at all. We list every one of them here — including the silent ones — because we believe you should know about all of them, not just the ones Android asks you about.
4.1 Permissions You Grant Through Dialogs
Android asks you for these individually, and you can review or revoke them anytime under Settings > Apps > SPAM-JAMR > Permissions.
Phone (read phone state, make calls, answer calls): Used to detect incoming call state and to power the call overlay's ANSWER and CALL BACK actions, which place or answer calls only when you tap those buttons. Never used to place calls on its own. Required for call screening to function.
Contacts (optional): Read locally to recognize trusted callers and support your whitelist. Your contacts are never uploaded, copied off-device, or shared.
Approximate location (optional): The App requests coarse location only — never precise/GPS location. On Android 12 and later, your settings will show this as "approximate" with no precise-location option, because the App does not request one. It is used locally to enhance regional area code intelligence. Declining this permission does not disable call screening; the App supports a privacy mode without it.
Notifications (Android 13+): Used to alert you about blocked calls, spam activity, and protection status. On Android 11–12, no prompt exists and notifications are enabled by default; you control them through notification settings on all versions.
4.2 Access You Grant Through System Settings
These are handled on Android settings screens rather than pop-up dialogs — one you select yourself, and one Android grants automatically alongside it.
Caller ID & spam app role: You select SPAM-JAMR as your call screening app under Android's Default apps settings. This system role is how the App receives incoming calls to evaluate, and it is the App's core function. You can reassign or remove the role at any time.
Display over other apps (optional): Used to show the real-time call analysis overlay during incoming calls. You do not grant this one manually: on Android 11 and later, Android grants it automatically when you select SPAM-JAMR as your call screening app, because it is tied to that role — and if the App ever loses the call screening role, Android revokes this permission with it. You can also revoke it yourself at any time under Special App Access (called "Display over other apps," or "Appear on top" on Samsung devices), or turn the overlay off in the App's settings after confirming a warning. If this capability is ever lost while you expect the overlay to be on, the App tells you — a one-time alert, a note on each screened call's notification, and a reduced protection score with a one-tap route to restore it.
4.3 Permissions Android Grants Automatically at Install
Android classifies these as low-risk "normal" permissions and grants them silently when the App installs — you are never prompted, and they do not appear in the main Permissions screen (only under "All permissions" in App info). We disclose them here anyway, with their exact purposes:
Internet and network state: Used solely for the public threat-data downloads described in Section 5, and to check connectivity before attempting them. No user data is ever uploaded. We call this out prominently because an app with network access deserves scrutiny — Section 5 describes exactly what the connection is used for, and Sections 2 and 3 describe what it is never used for.
Foreground service (phone call type): Required by Android so the call overlay and screening remain active for the duration of a call.
Run at startup: Used to restore your call protection automatically after your device restarts, so you are not left unprotected without knowing it.
Vibration: Used for notification vibration alerts.
4.4 What the App Does Not Request
SPAM-JAMR does not request or use: call log permissions (read or write), SMS/MMS permissions, microphone or call recording, camera, precise (GPS) location, accessibility services, or device administrator capabilities.
5. Network Activity: Downloads Only
SPAM-JAMR connects to the internet solely to download public threat intelligence data. These downloads work like fetching a public webpage — the requests do not contain your phone number, your callers' numbers, your contacts, your location, or any other personal data. Sources include:
FTC Do Not Call complaint data (api.ftc.gov) — aggregate, public-domain complaint volumes by area code, retrieved with date-range queries only
FCC and government open data (Socrata open data platforms) — public consumer complaint datasets
Area code database updates — downloaded from a public GitHub repository
You control data updates within the app and may disable them. Downloaded data is cached locally on your device.
6. Data Storage, Export, and Deletion
All app data lives in a local database on your device.
You may export a diagnostic report of your app data at any time from within the app; the export is generated locally and shared only where you choose to send it.
Uninstalling the app permanently deletes all app data. There is nothing to delete on our end, because we never had any of it.
7. Third Parties
We do not sell, rent, trade, or share personal information with anyone — because we do not have it. The app contains no third-party advertising SDKs, no analytics SDKs, and no social media integrations. Government data sources listed above receive standard, anonymous download requests only.
8. Children's Privacy
SPAM-JAMR is not directed at children under 13, and because the app collects no personal information from any user, it collects none from children.
9. Security
Because your data never leaves your device, its security is anchored in your device's own protections. The app additionally validates its internal broadcasts with signature verification and confines processing to its own sandboxed storage.
10. Changes to This Policy
If we change this policy, we will update the effective date above and publish the revised version at this address. Material changes will be noted in the app's release notes. Because the app collects no contact information, we cannot notify you individually — please review this page periodically.
