CALLBUNKER TERMS OF USE

Last Updated: September 18, 2026

AGREEMENT TO THESE TERMS

These Terms of Use (“Terms”) govern your access to and use of CallBunker, including the CallBunker mobile application, the website located at https://www.callbunker.com, and related products and services provided by CallBunker LLC (collectively, the “Services”).

CallBunker LLC (“CallBunker,” “we,” “us,” or “our”) is a Massachusetts limited liability company.

PLEASE READ THESE TERMS CAREFULLY.

By creating an account, accessing, purchasing, or using the Services, you agree to these Terms and our Privacy Policy.

If you do not agree to these Terms, do not use the Services.

  1. ABOUT CALLBUNKER

CallBunker is a communications protection service designed to give users greater control over who can reach them.

CallBunker may provide users with a dedicated CallBunker phone number through which supported calls and text messages can be received or sent.

Depending on the user’s settings and available features, unknown callers or senders may be required to complete a verification process before their communication is connected or delivered.

Verification methods may include PIN-based verification, voice-based verification, or other authentication methods introduced by CallBunker.

CallBunker features may include:

Features may change as CallBunker develops.

  1. CALLBUNKER IS AN ACCESS CONTROL SERVICE

CallBunker is designed to create an additional verification layer between unknown callers or senders and the CallBunker user.

A successful verification means only that the applicable CallBunker verification process was completed successfully.

It does not guarantee the caller’s or sender’s:

CallBunker does not guarantee that every spam call, scam, fraudulent communication, spoofed communication, malicious communication, unwanted message, or unauthorized caller will be detected, blocked, or prevented.

Users remain responsible for exercising reasonable judgment when communicating with unknown parties.

CallBunker is not a substitute for emergency services, law enforcement, financial fraud protection, carrier security services, or professional security services.

  1. PERSONAL NUMBERS AND CALLBUNKER NUMBERS

CallBunker may assign a dedicated telephone number to a user’s account.

The CallBunker number functions as an access point through which supported CallBunker calling, messaging, and verification features may operate.

Communications made directly to a user’s personal telephone number may not pass through CallBunker’s verification systems.

Accordingly, users who want the strongest available CallBunker protection should consider keeping their personal number private and providing their CallBunker number when they want communications to pass through CallBunker’s supported verification features.

A CallBunker number does not protect communications that bypass the CallBunker service.

  1. CALLBUNKER NUMBER ASSIGNMENT

Telephone numbers made available through CallBunker are provided through telecommunications infrastructure providers and remain subject to carrier, provider, regulatory, technical, and availability requirements.

Assignment of a CallBunker number does not transfer ownership of the telephone number to the user.

Instead, users receive a limited right to use an assigned number while their account remains eligible for the applicable CallBunker service.

CallBunker may reclaim, replace, suspend, or change an assigned number when reasonably necessary because of:

CallBunker does not guarantee permanent availability of any particular telephone number.

Users may have the ability to change their CallBunker number subject to the product rules, limits, and any fees disclosed before the change is completed.

  1. ACCOUNT REGISTRATION

Certain CallBunker features require an account.

You agree to provide accurate, current, and complete registration information and to update that information when necessary.

You are responsible for protecting your account credentials and for activity occurring through your account.

You must promptly notify CallBunker if you believe your account, credentials, personal number, or CallBunker number has been compromised.

CallBunker may require verification of your telephone number or other account information before providing certain features.

  1. PHONE NUMBER VERIFICATION

CallBunker may require users to verify ownership or control of their personal mobile number through an SMS one-time password, verification code, or another supported verification method.

If you change the personal number associated with your account, CallBunker may require verification of the new number before completing the change.

You may not register or use a telephone number that you do not own, control, or have authorization to use.

  1. CALLER AND SENDER VERIFICATION

CallBunker users may configure verification requirements for communications received through their CallBunker number.

Depending on available features and user settings, an unknown caller or sender may be required to complete PIN, voice, or another supported verification method.

A failed verification attempt may result in the communication being rejected, blocked, or otherwise restricted.

Successful verification may allow the communication to proceed and, depending on user settings and CallBunker functionality, may affect how that caller or sender is treated during future communications.

Users remain responsible for managing their Trusted and Blocked lists and deciding whom they permit to contact them.

  1. VOICE VERIFICATION

CallBunker’s voice-verification feature may use real-time speech recognition provided through our telecommunications provider.

CallBunker does not record or store raw voice audio from voice-verification attempts.

During voice verification, audio may be streamed through Twilio’s communications infrastructure for real-time speech recognition. Spoken information is converted into text for comparison with the applicable verification phrase.

CallBunker does not create or maintain a stored raw audio recording or voiceprint as part of this verification process.

Additional information concerning voice-data processing is available in our Privacy Policy.

  1. CONTACT ACCESS

CallBunker may provide optional features allowing users to access contacts stored on their device.

Contact access requires the applicable device permission.

The user’s complete contact book is not bulk uploaded or synchronized to CallBunker’s backend servers.

Contacts may be accessed locally to allow users to:

If a user intentionally adds a specific telephone number to a Trusted or Blocked list, that specific number may be transmitted to and stored by CallBunker so the selected filtering preference can be provided.

Additional information is available in our Privacy Policy.

  1. PROTECTED TEXT MESSAGING

CallBunker may provide SMS functionality through assigned CallBunker numbers.

Depending on the user’s settings, incoming messages from unknown senders may be subject to verification before delivery.

When verification is required, a message from an unverified sender may be temporarily held while the sender completes the verification process.

If verification is successfully completed, the applicable message may be delivered to the CallBunker user’s messaging interface.

If verification is not successfully completed, a pending message may expire without being delivered.

Pending or unverified messages are currently removed from CallBunker’s active pending-message system after 24 hours if the required verification is not completed.

Delivered messages may be stored to provide the user’s in-app conversation history.

CallBunker currently uses MongoDB Atlas as cloud database infrastructure for message history and related account information.

Messaging functionality depends on telecommunications providers, carriers, network availability, registration requirements, and other infrastructure outside CallBunker’s exclusive control.

CallBunker does not guarantee that every message will be delivered, delivered immediately, successfully screened, or protected from spam, fraud, spoofing, or abuse.

  1. SMS PROGRAM TERMS

CallBunker may send SMS communications relating to:

By expressly opting in to an applicable CallBunker SMS program, you consent to receive the types of messages described when consent is provided.

Message frequency varies based on account activity, features used, communications requested, and the applicable messaging program.

Message and data rates may apply.

Where applicable, reply STOP to opt out of eligible recurring SMS communications.

Where applicable, reply HELP for assistance or contact CallBunker at CallBunkerapp@gmail.com.

Consent to receive optional or promotional SMS messages is not a condition of purchasing CallBunker services.

Consent to one messaging program does not constitute consent to unrelated marketing or promotional messaging.

CallBunker does not sell, rent, or share mobile phone numbers, SMS opt-in information, or SMS consent with third parties or affiliates for their own marketing or promotional purposes.

Wireless carriers are not liable for delayed or undelivered messages.

Additional information regarding mobile information and messaging privacy is available in the CallBunker Privacy Policy.

  1. SMS CONSENT

Where consent is required, CallBunker will obtain applicable consent before sending covered SMS communications.

SMS consent must be provided through the applicable opt-in process and is separate from general acceptance of these Terms when separate consent is required.

Merely creating a CallBunker account or accepting these Terms does not constitute consent to receive unrelated promotional SMS messages.

Users may withdraw consent from eligible recurring messaging programs by following the applicable opt-out instructions, including replying STOP where supported.

CallBunker will honor applicable opt-out requirements.

Certain messages necessary to complete a user-requested transaction, respond to a request, maintain account security, or provide a specifically requested service may be treated differently where permitted by applicable law and messaging requirements.

  1. MESSAGE STORAGE

Delivered messages may be stored in CallBunker’s backend systems so that users can access their in-app conversation history.

Delivered messages are currently retained until they are deleted by the user or authorized CallBunker personnel, the account is closed, or deletion is otherwise required under CallBunker’s policies or applicable law.

Pending messages from senders who have not completed required verification are stored separately and automatically expire from the active pending-message system after 24 hours if verification is not completed.

Users should not use CallBunker as their sole permanent archive for important communications.

CallBunker may modify reasonable retention practices as the Services evolve, subject to the Privacy Policy and applicable law.

  1. SUBSCRIPTIONS

Certain CallBunker features require a paid subscription.

Available subscription plans, prices, billing periods, trials, and included features will be displayed before purchase.

Unless otherwise stated at the time of purchase, subscriptions may automatically renew until canceled.

Subscription pricing and offerings may change from time to time in accordance with applicable law and payment-provider requirements.

  1. FREE TRIALS

CallBunker may offer eligible users a free trial.

The duration and specific terms of the trial will be disclosed when the offer is presented.

Where a trial is connected to an automatically renewing subscription, the subscription may begin and the applicable payment method may be charged when the trial ends unless the subscription is canceled in accordance with the applicable purchase terms.

CallBunker may modify, limit, or discontinue promotional trial offers.

  1. GOOGLE PLAY BILLING

Purchases made through the Android version of CallBunker may be processed through Google Play.

Google Play’s applicable payment and subscription terms apply to transactions it processes.

CallBunker may receive transaction and subscription information necessary to determine subscription status but does not need to receive or store the user’s complete payment-card number when Google Play processes the transaction.

Users may be required to manage or cancel subscriptions through their Google Play account.

Uninstalling the CallBunker application or deleting a CallBunker account does not necessarily cancel an active Google Play subscription.

Users are responsible for canceling subscriptions through the applicable payment provider where required.

  1. REFUNDS

Refund eligibility for purchases processed through Google Play is subject to applicable law, Google Play policies, and any additional refund rights expressly provided by CallBunker.

CallBunker does not guarantee refunds except where required by applicable law or applicable platform policies.

  1. ACCEPTABLE USE

You agree to use CallBunker only for lawful purposes.

You may not use CallBunker to:

CallBunker may investigate suspected abuse and may restrict, suspend, or terminate accounts when reasonably necessary to protect users, CallBunker, telecommunications providers, carriers, or others.

  1. TELECOMMUNICATIONS AND CARRIER REQUIREMENTS

CallBunker relies on telecommunications providers, mobile carriers, messaging providers, internet providers, and other third parties to provide portions of the Services.

Calling and messaging functionality may therefore be subject to:

CallBunker may modify, restrict, or suspend communications functionality when reasonably necessary to comply with these requirements.

  1. EMERGENCY SERVICES

CallBunker should not be relied upon as the sole means of contacting emergency services.

For emergencies, use your device’s standard telephone service or another appropriate method to contact emergency responders.

Do not rely on CallBunker caller verification, protected messaging, or other CallBunker functionality for emergency communications.

  1. USER COMMUNICATIONS

Users may transmit communications through CallBunker’s calling and messaging functionality.

You remain responsible for communications you initiate through the Services.

You represent that you have the rights and lawful authority necessary to transmit content you send using CallBunker.

CallBunker does not claim ownership of private communications merely because they are transmitted or stored through CallBunker infrastructure.

You grant CallBunker and its service providers the limited rights necessary to process, transmit, route, display, store, secure, and deliver communications and otherwise provide the Services.

These operational rights do not permit CallBunker to sell your private message content for third-party advertising.

  1. THIRD-PARTY SERVICE PROVIDERS

CallBunker currently relies on service providers including:

These providers may process information necessary to perform their respective services.

CallBunker’s use of personal information and service providers is described further in our Privacy Policy.

CallBunker does not currently use third-party advertising SDKs within the CallBunker application.

  1. INTELLECTUAL PROPERTY

CallBunker and its licensors own the CallBunker software, website, branding, logos, designs, interfaces, documentation, and other proprietary content made available through the Services, except for content owned by users or third parties.

Subject to these Terms, CallBunker grants you a limited, nonexclusive, nontransferable, revocable license to use the Services for their intended purpose.

You may not copy, modify, reverse engineer, distribute, sell, sublicense, or commercially exploit CallBunker software or proprietary content except where permitted by applicable law or expressly authorized by CallBunker.

This provision does not transfer ownership of your private calls, messages, contacts, or personal information to CallBunker.

The Privacy Policy is incorporated into these Terms by reference.

  1. ANALYTICS AND ADVERTISING

CallBunker does not currently use third-party advertising SDKs, behavioral advertising systems, or third-party analytics or crash-reporting platforms such as Google Analytics, Sentry, or Mixpanel within the CallBunker application.

If these practices materially change, CallBunker will update its disclosures as appropriate.

  1. SERVICE AVAILABILITY

We work to maintain reliable Services, but we cannot guarantee uninterrupted or error-free operation.

The Services may be temporarily unavailable because of:

CallBunker may modify, suspend, discontinue, or replace features when reasonably necessary.

  1. ACCOUNT SUSPENSION AND TERMINATION

CallBunker may suspend or terminate access to the Services if we reasonably determine that:

Where appropriate and legally permitted, CallBunker may provide notice or an opportunity to address the issue.

  1. USER TERMINATION

You may stop using CallBunker at any time.

Account deletion and subscription cancellation are separate actions.

Deleting your CallBunker account or uninstalling the application may not automatically cancel an active subscription processed through Google Play or another payment provider.

Users remain responsible for canceling applicable subscriptions through the payment provider where required.

TO THE FULLEST EXTENT PERMITTED BY LAW, CALLBUNKER AND THE SERVICES ARE PROVIDED “AS IS” AND “AS AVAILABLE.”

(A) THE AMOUNT YOU PAID TO CALLBUNKER FOR THE SERVICES DURING THE SIX MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM; OR

Some jurisdictions do not permit certain liability limitations, so portions of this section may not apply to you.

If a change materially affects users’ rights or obligations, CallBunker may provide additional notice where required by applicable law.

Continued use of the Services after updated Terms become effective constitutes acceptance to the extent permitted by applicable law.
