OneSignal Additional Product Terms

Effective July 23, 2026

OneSignal Additional Product Terms

These OneSignal Additional Product Terms ("Additional Product Terms") describe the specific terms that apply to certain OneSignal services, products or features offered by OneSignal (each, an "Additional Product"). These Additional Product Terms are incorporated into, and form a part of, the Pro Terms or Master Services Agreement, or other equivalent agreement (as applicable, the "Agreement") between OneSignal and the entity that entered into the Agreement ("Customer").

In the event of a conflict between the Agreement and these Additional Product Terms, the applicable Additional Product Terms will control to the extent of the conflict. A violation of these Additional Product Terms is a violation of the Agreement. Capitalized terms not defined herein have the meaning given to them in the Agreement.

Amendments. OneSignal may change these Additional Product Terms upon updating its terms at https://onesignal.com/additional-product-terms, except that Section 1.5 (No Training on Customer Data), once incorporated into a renewal Order Form, may only be modified by written amendment signed by both parties.

1. AI Tools

This Section 1 establishes universal provisions that apply to all AI Tools that OneSignal makes available as part of the Services. AI Tools are identified in the Services with an AI indicator or are otherwise obvious from context. "AI Tools" is defined in the Agreement and includes, without limitation, OneSignal AI, AI Compose, and AI-assisted content generation tools.

1.1 Pricing and Usage.

OneSignal does not currently charge additional fees for use of the AI Tools. OneSignal reserves the right to introduce fees for AI Tools upon reasonable prior notice to Customer. OneSignal may monitor, limit, or suspend access to the AI Tools if usage is believed to circumvent rate limits, negatively affect service performance or integrity, or violate the Agreement or the Acceptable Use Policy.

1.2 Retention.

OneSignal retains AI Conversation Data ("AI Conversation Data" means conversation history, prompts, and other input and output data generated through Customer's use of the AI Tools) for a period disclosed in OneSignal's AI Data Practices documentation at https://documentation.onesignal.com/docs/en/ai-data-practices (provided for informational purposes only and does not form part of this Agreement), after which it is deleted in the ordinary course. Retention at the AI sub-processor inference layer is governed by OneSignal's sub-processor terms and disclosed in the OneSignal DPA and List of Subprocessors. OneSignal may update its retention policy from time to time by updating its AI Data Practices documentation.

1.3 Organization Level Disable.

Customer may disable the AI Tools, in whole or by feature where granular controls are available, at the organization level. For more information, see OneSignal's AI Data Practices documentation at https://documentation.onesignal.com/docs/en/ai-data-practices (provided for informational purposes only and does not form part of this Agreement).

1.4 AI Sub-Processor Terms.

Use of the AI Tools is subject to the third-party terms applicable to OneSignal's AI sub-processors, which are incorporated herein by reference. The currently designated AI sub-processors and the applicable third-party terms are disclosed in OneSignal's List of Subprocessors at https://onesignal.com/list-of-subprocessors. OneSignal may update its AI sub-processors from time to time in accordance with the OneSignal DPA.

1.5 No Training on Customer Data.

OneSignal will not use Customer Content, Subscriber Data, or AI Conversation Data to train, fine-tune, or otherwise improve any AI or machine learning model; provided that pseudonymized or aggregated technical operational identifiers (including hashed IP addresses and device identifiers) may be used for platform operations, security monitoring, and service improvement. For the avoidance of doubt, OneSignal may use OneSignal Analytics Data (as defined in the Agreement), including for training, developing, and improving machine learning and artificial intelligence models, provided that such models are trained solely on OneSignal Analytics Data and not on Customer Content or Subscriber Data. Once this Section 1.5 is incorporated by reference into an Order Form, it may only be modified by written amendment signed by both parties, notwithstanding the general amendment provision of these Additional Product Terms.

1.6 Service Quality Review.

OneSignal may permit authorized personnel to access and review permanently anonymized evaluation logs derived from AI Tools interactions retained under Section 1.2 for service quality purposes, such as identifying errors, evaluating output accuracy, and improving AI-powered features. Access is limited to authorized OneSignal personnel subject to confidentiality obligations consistent with those applicable to the Services. Such access does not constitute use of Customer data to train or fine-tune AI models and does not limit the no-training commitment in Section 1.5.

1.7 OneSignal Slack Agent.

OneSignal Slack Agent ("Slack Agent") is an AI-powered assistant that Customer may install in its Slack workspace to access and interact with its OneSignal account data and Services through a conversational interface. The Slack Agent is currently offered as a Trial or Beta feature; Section 4 of these Additional Product Terms applies during the beta period and controls in the event of any conflict with this Section 1.7.

Access and Actions. Once installed, the Slack Agent may access Customer's platform data, including campaign analytics, notification templates, and subscriber data, and may take actions within the Services on Customer's behalf, such as creating and modifying notification templates and drafting messages. Customer is responsible for all actions taken by the Slack Agent on its behalf, including any fees incurred as a result of those actions. Actions taken by the Slack Agent are deemed actions of Customer.

Installation and Configuration. Customer is responsible for installing and configuring the Slack Agent, including managing which Slack workspace members may interact with it and what OneSignal account data and functionality they may access through it. Customer should configure access to include only the data and actions Customer intends to make available through its Slack workspace.

Data Handling. The Slack Agent is powered by OneSignal's AI infrastructure and is subject to the same data handling terms as the AI Tools described in Sections 1.2 through 1.6 of these Additional Product Terms, including the no-training commitment in Section 1.5 and the service quality review provisions in Section 1.6.

2. RCS Messaging

The Services include Rich Communication Services ("RCS") messaging features. The terms in this Section 2 apply to Customer's use of RCS through the Services and are in addition to Customer's obligations under the Acceptable Use Policy.

2.1 RCS Brand Verification and Non-Refundable Fees.

Customer's ability to send RCS messages is subject to a brand verification process administered by Google and applicable carriers. As part of this process, Customer is required to provide information including its brand name, brand colors, logo images, and an RCS agent description. This information will be shared with Google, applicable carriers, and OneSignal's RCS service providers (including their downstream partners) as necessary to complete verification and enable RCS messaging. OneSignal may request additional information from Customer to complete or maintain verification. Fees paid by Customer for RCS brand verification (whether to OneSignal, its service providers, or Google) are non-refundable, regardless of whether verification is approved, withdrawn, or revoked.

2.2 Acceptable Use, Content Vetting, and Consent.

Customer's use of RCS is subject to the Acceptable Use Policy at https://onesignal.com/aup, including all content, consent, opt-in, and vetting requirements applicable to mobile messaging. Customer must obtain and maintain valid opt-in and consent records for all RCS recipients in accordance with applicable law and applicable carrier requirements. OneSignal may suspend, throttle, or disable Customer's RCS messaging access if Customer's usage patterns suggest abuse, including, without limitation, extremely high-frequency or high-volume sending patterns commonly associated with messaging pumping or other abusive practices.

2.3 Charges, Message Type Upgrades, and Customer Liability.

Customer is liable for all RCS usage charges incurred under its account, including charges resulting from actions taken by Customer's Authorized Users or any Customer AI Agent operating on Customer's behalf.

RCS message pricing varies by message type, region, and content. Specific message parameters (e.g., character count, the inclusion of images or media attachments, and personalization) may cause a message to be sent as, or automatically upgraded to, a higher-priced message type (for example, from RCS Basic to RCS Single in international regions, or from RCS Rich to RCS Rich Media in the United States). RCS Single and RCS Rich Media are typically priced approximately three times (3x) the rate of RCS Basic and RCS Rich, respectively. These upgrades occur automatically at the time the message is processed for delivery and OneSignal cannot gate messages in advance of delivery to prevent such upgrades. Customer is responsible for monitoring its RCS message content and managing its usage to control total charges. OneSignal may provide estimation tools to assist Customer in anticipating charges; however, such tools provide estimates only and do not guarantee final charges due to factors including personalization, regional rules, and final delivery characteristics.

2.4 Uncontracted RCS Products.

Charges incurred for RCS message types not specifically contracted for in the Order Form (including, by way of example, RCS Single charges incurred when Customer has contracted only for RCS Basic) will be billed to Customer at the rates set forth under the "Uncontracted Products" section of the Order Form. Customer's continued use of the Services following such charges constitutes acceptance of the applicable rates.

2.5 Service Provider Pass-Through Restrictions.

OneSignal provides RCS messaging through one or more third-party service providers (including, as of the Effective Date, Twilio and Infobip). Customer's use of RCS is subject to applicable restrictions imposed by such providers as well as the Acceptable Use Policy. Customer agrees to comply with applicable provider content, vetting, and use restrictions to the same extent as if Customer were a direct customer of the provider. This Section 2.5 applies regardless of whether Customer accesses the Services through a OneSignal-managed account or through any main or sub-account configuration.

3. Third-Party Service Integrations and Customer AI Agent Connections

If Customer opts to include or enable any optional third-party service integrations in connection with Customer Properties, Customer will be bound by the terms and conditions and privacy policy of such third party. OneSignal is not responsible or liable for any Third Party Services, or for the use of any data that Customer authorizes to disclose to them via the Services or otherwise.

3.1 Customer AI Agent and MCP Connections.

For purposes of this Section 3.1: "Customer AI Agent" means any software, automated system, or large language model (LLM) powered tool that initiates API calls to the Services on Customer's behalf without direct human input on each action, including autonomous agents and orchestration pipelines; and "MCP Connection" means any programmatic interface between the Services and a Customer AI Agent using the Model Context Protocol or a functionally equivalent machine-to-machine protocol.

Customer is responsible for configuring the scope of data and actions that any Customer AI Agent or third-party AI or LLM service acting on Customer's behalf may access through an MCP Connection, and should configure MCP Connections to include only the systems, data, and accounts Customer intends to make available. Customer acknowledges that OneSignal data accessed through an MCP Connection, such as Subscriber Data, event data, and analytics, may be transmitted to and processed by the third-party AI or LLM service Customer has chosen; Customer is solely responsible for ensuring such transmission complies with applicable data protection laws, its privacy notices, and its agreements with that service; and OneSignal is not a party to, and accepts no responsibility under, any agreement between Customer and its chosen third-party AI or LLM service. Any such third-party AI or LLM service is a Third Party Service under the Agreement. Customer remains liable under the Agreement for all actions taken by any Customer AI Agent or third-party AI or LLM service acting on Customer's behalf through MCP Connections. Actions taken by a Customer AI Agent through an MCP Connection are deemed actions of Customer, and Customer is responsible for any fees incurred as a result of erroneous or unintended actions taken by a Customer AI Agent.

The current status of delete capability for the Customer AI Agent feature is described in the AI Data Practices documentation at https://documentation.onesignal.com/docs/en/ai-data-practices (provided for informational purposes only and does not form part of this Agreement).

OneSignal may, in its reasonable discretion, immediately suspend or throttle Customer's MCP Connections without suspending Customer's account as a whole, if OneSignal reasonably believes such connections are causing or are likely to cause: (i) infrastructure degradation affecting other customers; (ii) unauthorized access to or exfiltration of Customer or third-party data; (iii) violation of the AUP or applicable law; or (iv) material risk to the security or integrity of the Services. OneSignal will notify Customer promptly following any such suspension and will restore access upon Customer's remediation of the applicable issue.

4. Trials and Betas

For features offered as Trials and Betas, this Section 4 applies in addition to any feature-specific terms in these Additional Product Terms, and this Section 4 controls in the event of a conflict during the Trial or Beta period.

OneSignal may offer optional free, trial, beta, or early access to the Services or a feature thereof ("Trials and Betas"). Use of Trials and Betas is permitted only for Customer's internal evaluation during the period designated by OneSignal on the Order (or if not designated, 30 days). Either party may terminate Customer's use of Trials and Betas at any time for any reason. Trials and Betas may be inoperable, incomplete, or include features never released. Notwithstanding anything else in the Agreement, OneSignal offers no warranty, indemnity, SLA, or support for Trials and Betas, and its liability for Trials and Betas will not exceed US$500. Features made available as Trials and Betas may involve use of OneSignal's AI infrastructure for AI-powered functionality prior to the publication of full data practice documentation. Customer's participation in any such Trial or Beta constitutes its acknowledgment of such use. OneSignal will update its data processing documentation upon general availability of the applicable feature.

5. Optional Services

Customer may purchase optional Services, such as premium support or onboarding Services, if included in an Order Form.
