Welcome to STRTALK.
These Terms of Use (“Terms”) govern your access to and use of the STRTALK mobile and desktop application, website, and any associated services (collectively, “STRTALK” or the “Service”), which are provided to you by SOURCELESS INC., a company incorporated under the laws of Delaware, USA, with its registered office at United States of America16192 Coastal Highway, Lewes,DE 19969, USA (“we”, “us”, or “our”).
STRTALK is a privacy-focused communication platform that enables users to exchange messages, make voice and video calls, and share files securely using end-to-end encryption and peer-to-peer transmission based on the proprietary Voice Over Blockchain Protocol (VOBP). Our infrastructure is designed to minimize data collection and ensure that your communication remains private and under your control.
By downloading, installing, accessing, or using STRTALK, you confirm that you have read, understood, and agreed to be bound by these Terms. If you do not agree with any part of these Terms, you should not use the Service.
These Terms apply to all users of STRTALK, whether registered via a phone number or via a STR.Domain (or similar organizational identifier), and regardless of the device or operating system used.
STRTALK is a software-based communication platform made available through mobile and desktop applications (“STRTALK App”), available for Apple, Android and Windows devices, that allows users to engage in secure, real-time communication. The services provided by STRTALK include, but are not limited to:
The Service is architected to operate using end-to-end encryption and a peer-to-peer transmission model, both of which are implemented through STRTALK’s proprietary protocol, known as the Voice Over Blockchain Protocol (VOBP).
The encryption keys necessary to secure user communication are generated and stored locally on the user’s device. STRTALK does not store, duplicate, or otherwise have access to user encryption keys, message content, call recordings, or shared files. Communications are encrypted before transmission and are decrypted only on the intended recipient’s device.
The Service is made available solely for lawful personal or organizational use, subject to these Terms and applicable laws. STRTALK reserves the right to modify, suspend, or discontinue any aspect of the Service at any time, in whole or in part, for operational, legal, technical, or security reasons.
While we aim to ensure a stable and secure service, we do not guarantee that STRTALK will always function without interruption, delays, or errors. The Service may be modified, suspended, or discontinued in whole or in part at any time, with or without prior notice, including for maintenance, updates, or technical or legal reasons.
Due to the design of STRTALK and the use of VOBP, all messages, calls, and files are encrypted and decrypted locally on the user’s device. We do not store message content or user encryption keys, and we are not able to access or retrieve this information. You are solely responsible for securing your own device and preserving your own data.
STRTALK routes communication directly between devices whenever technically possible. In cases where network limitations require the use of relays or intermediary nodes, the data remains end-to-end encrypted and is not accessible to STRTALK or any third party.
STRTALK does not provide financial or payment services. If you use CCOIN, this is a separate service operated by CCOIN FINANCE CORPORATE STRUCTURE CO., LTD, and is subject to its own terms and privacy policy. STRTALK bears no responsibility for any services, data processing, or disputes arising from the use of CCOIN.
We reserve the right to improve, update, or otherwise modify the Service or any of its features from time to time. These changes may include security enhancements, performance improvements, or changes required by applicable law.
There are important differences between our Services and your mobile phone and a fixed-line telephone and SMS services. Our Services do not provide access to emergency services or emergency services providers, including the police, fire departments, or hospitals, or otherwise connect to public safety answering points. You should ensure you can contact your relevant emergency services providers through a mobile phone, a fixed-line telephone, or other service.
Access to and use of the STRTALK application and its services is permitted only to individuals who meet the following criteria:
By registering for or using the Service, you represent and warrant that you meet all of the above eligibility requirements. STRTALK reserves the right to restrict or terminate access to the Service if we reasonably believe that you do not meet these requirements.
To use STRTALK, you must create an account, which may be based on:
When registering, you agree to:
STRTALK does not require users to provide a real name or additional personal details for general use of the Service. However, where a STR.Domain is issued by an organization (e.g. employer or institution), the terms of use or internal policies of that organization may also apply. In such cases, STRTALK disclaims responsibility for that organization's use or processing of personal data.
If you register using a phone number, your STRTALK account is uniquely tied to that number. Changing your number does not transfer your account — a new number will result in a new STRTALK account with no access to prior messages, calls, contacts, or encryption keys.
Additionally, if you log out of the app or uninstall it without exporting your data (where possible), all communication history and device-stored encryption keys associated with that number will be permanently lost. This is a direct consequence of STRTALK’s security design: we do not retain, back up, or sync user content or keys on our servers.
For privacy and security reasons, STRTALK does not support account migration, account linking, cloud-based backups, or data recovery services. Users are fully responsible for safeguarding their own data and, where available, using export features or device-level backups prior to changing identifiers or uninstalling the app.
We strongly recommend that users ensure their device is securely stored and that they understand the consequences of removing or resetting STRTALK without having preserved their data locally.
Each STRTALK account registered using a phone number is uniquely and exclusively associated with that specific number. Only one active STRTALK account may be used per phone number at a time.
You may not have the possibility to:
STRTALK does not support account aliasing, cloning, or number-based account reactivation. If a phone number is reassigned (e.g., by a telecom provider), STRTALK considers the new user of that number to be a separate user for all purposes under these Terms.
To support data minimization principles under applicable data protection laws, and to maintain the efficiency and security of the Service, STRTALK reserves the right to deactivate and delete user accounts that have remained inactive for an extended period, as set out below.
If your account shows no meaningful activity — such as login events, message exchanges, call attempts, or key exchanges, STRTALK may, at its discretion:
This process is conducted without retaining, duplicating, or archiving any user content, as STRTALK does not store messages, files, call history, or encryption keys on its servers. Once an account is deleted due to inactivity, all related data that may exist on the device (e.g. encrypted chat history or local session tokens) becomes permanently inaccessible unless the user has taken prior action to preserve it locally.
Where feasible, STRTALK may attempt to notify the user in advance of the scheduled deletion, using the last known contact method associated with the account. However, no guarantee of notice is provided, and deletion may occur without warning if the user cannot be reached or identified through valid credentials.
Reactivation of a deleted account is not possible, and any future use of the Service would require re-registration as a new user. STRTALK shall not be liable for any loss of data resulting from account inactivity or deletion in accordance with this section.
Due to the technical design of STRTALK — which prioritizes user privacy and data security through local encryption and device-based authentication — users are solely responsible for maintaining access to the credentials and devices associated with their STRTALK account.
If you lose access to your:
then STRTALK will not be able to restore access to your account or recover any associated data. We do not have the technical means to decrypt or reconstruct communication content under any circumstances, including at the user’s request.
As a result, we cannot assist with account recovery, reset or regenerate your encryption keys, or recover or retrieve any lost or deleted content (e.g., messages, calls, files).
It is your responsibility to:
You acknowledge and agree that STRTALK shall not be liable for any loss of access, data, or functionality arising from your inability to authenticate or recover your account in accordance with this section.
By using STRTALK, you agree to use the Service in a lawful, responsible, and respectful manner. This means you will not use STRTALK to violate any laws, harm others, interfere with the platform, or misuse its features. Also, you must not engage in activity that violates our Terms or other terms and policies that may apply to your use of our Services. To this end, you are solely responsible for your actions and communications while using the Service.
To protect the privacy, security, and integrity of the STRTALK platform and its users, you agree to use the Service only for its intended and lawful purposes. You shall not use, or attempt to use, STRTALK in any manner that is prohibited under these Terms.
You may not use the Service to:
You must not, directly or indirectly, nor permit others to:
Due to STRTALK’s end-to-end encryption and peer-to-peer architecture, we do not have access to your communication content and are unable to monitor or moderate the use of the Service in real time.
However, we reserve the right to:
You are solely and fully responsible for your conduct while using the Service, as well as for any content, data, or communications you choose to transmit, share, or make accessible through STRTALK. In particular, you must ensure that your use of the Service:
If we become aware of behavior that appears to violate these Terms or applicable law, we may:
Disabling or suspending your account will be in accordance with the “Termination” section below.
We reserve the right to take action in accordance with applicable legal obligations and proportionality principles, even if we cannot view or verify the actual message content.
STRTALK may enable access to certain services provided by third parties, such as payment functionality that allows users to send or receive financial assets or perform financial transactions through third-party platforms (e.g., CCOIN or other integrated financial entity).
These services are made accessible through the STRTALK interface for user convenience but are operated, controlled, and provided independently by the relevant third-party service providers.
When you choose to use any such integrated service, including initiating a financial transaction or accessing a linked wallet, you acknowledge and agree that:
Where available, users may access a separate payment service, CCOIN, which is operated by CCOIN FINANCE CORPORATE STRUCTURE CO., LTD, a legally distinct entity from SOURCELESS INC. The terms and conditions, privacy policies, and legal responsibilities for STRTALK PAY are entirely separate from these Terms and will be made available within the STRTALK app or website through direct links or API integration.
Any issues, complaints, or support requests regarding payment functionality or related financial services must be directed to CCOIN FINANCE CORPORATE STRUCTURE CO., LTD in accordance with their own user agreement.
Certain features of the STRTALK Service rely on or support integration with third-party providers for core functionality, including but not limited to:
Where such integrations are enabled, the third-party provider may receive limited technical data (e.g., phone number) strictly for the purpose of delivering the intended service. These providers operate independently and are governed by their own terms of use and privacy policies.
STRTALK does not control or assume responsibility for the data practices, availability, or security of such third-party services. By using STRTALK features that depend on these integrations, you acknowledge that:
The inclusion of any third-party service within the STRTALK platform does not imply endorsement or affiliation. STRTALK provides such integrations on an “as-is” basis and disclaims all responsibility for the accuracy, functionality, or availability of third-party systems.
You acknowledge that your interactions with third-party providers, including any contractual, financial, or legal relationships, are solely between you and those providers.
All content you create, transmit, or share via the STRTALK Service — including but not limited to messages, audio, video, images, documents, and other data (“User Content”) — remains fully owned by you. By using the Service, you do not transfer, assign, or license any intellectual property rights in your User Content to STRTALK, except where provided otherwise.
You retain all intellectual property rights, moral rights, and any other proprietary interests you may hold over the User Content, subject to applicable law. STRTALK does not assert any editorial control, licensing claims, commercial rights, or downstream use of your content, and does not index, profile, or catalog User Content for internal or external use.
As the content owner, you are solely responsible for:
You understand and agree that STRTALK's role is strictly limited to enabling the encrypted transmission of communications between users. To this effect, in order to operate and provide our Services, you grant STRTALK a worldwide, non-exclusive, royalty-free, sublicensable, and transferable license to use, reproduce, distribute, create derivative works of, display, and perform the information that you upload, submit, store, send, or receive on or through our Services. The rights you grant in this license are for the limited purpose of operating and providing our Services.
STRTALK does not pre-screen, monitor, or store the content of communications between users. We do not engage in content moderation or filtering, and we are not able to verify, remove, or restore any messages, files, or media shared via the Service.
While STRTALK may implement technical safeguards to protect platform stability and detect abusive usage patterns, we do not monitor private conversations, and we disclaim any responsibility for the content exchanged between users.
All intellectual property rights in and to the STRTALK application, including but not limited to the software code, user interface, design elements, logos, trademarks, service marks, technical architecture, and official documentation (collectively, the "STRTALK Materials") are and shall remain the exclusive property of STRTALK, or its licensors where applicable.

This license is for the sole purpose of enabling you to use our Services in the manner permitted by our Terms. No licenses or rights are granted to you by implication or otherwise, except for the licenses and rights expressly granted to you.

STRTALK is provided as a free, encrypted communication platform. We continuously work to improve the performance, security, and functionality of the Service.

Service availability may be affected by planned or unplanned interruptions, including for:
You may terminate your use of STRTALK at any time by deleting the app from your device. If your account is based on a phone number, this action will result in permanent loss of access to that account and all associated data, including messages and encryption keys, which are stored locally on your device and not recoverable by STRTALK.
No separate cancellation process is required. Simply uninstalling the app or ceasing to use the Service constitutes your voluntary termination.
We reserve the right to suspend or terminate your access to STRTALK at any time, with or without prior notice, if:
Termination for cause may follow a warning or notice period where appropriate, but immediate termination is permitted in serious or urgent cases. If your account is deleted or disabled by STRTALK under this clause, all local data will be permanently lost, and you will need to re-register to use the Service again.
If you believe your account was suspended or disabled in error, you may contact our support team at [email protected]. Please note that due to the nature of STRTALK’s encryption model, we may be unable to verify, investigate, or restore any content or user identity following deletion.
We may update or modify these Terms of Use from time to time to reflect:
When we make material changes to these Terms, we will publish the updated version on our website and/or within the STRTALK application, along with the effective date of the update. The latest version will always be available at https://privacy.strtalk.app or through the app interface.

If informal resolution is unsuccessful, either party may propose mediation before a neutral mediator, in accordance with applicable USA alternative dispute resolution procedures.
If mediation or arbitration is not applicable or not agreed, any legal proceedings relating to the Service or these Terms shall be brought before the competent Delaware courts.

We reserve the right to designate that certain features or services within the STRTALK application may be subject to separate terms and conditions. Where applicable, you will be given the opportunity to review and accept such terms before using those features.
STRTALK is operated under Delaware law and intended for use in jurisdictions where its operation is lawful.
