Usage Rules for Privacy-Preserving Temporary SMS Numbers

Welcome to the formal guidelines for using our privacy-first temporary SMS numbers service. This document is designed for business clients who require reliable messaging capabilities while minimizing personal data exposure. Built on a scalable, secure foundation and integrated with the PlastinkaCo infrastructure and the yodayo ecosystem, our platform provides virtual numbers that mask end-user identities, protect sensitive data, and streamline verification and communications workflows.

Format and Intent

The format of these rules isRules of Use. It defines how you may provision, operate, monitor, and terminate temporary numbers, as well as the responsibilities of you as a customer and ours as a service provider. By engaging with the service, you agree to adhere to these rules, to comply with applicable laws, and to implement security controls appropriate to your risk posture. The rules are written to be actionable for developers, security leads, product managers, and business executives alike.

Core Principles: Privacy-First by Default

Our approach centers on privacy protection throughout the lifecycle of temporary numbers. The core principles include data minimization, purpose limitation, strong access controls, and transparent data handling. Temporary numbers are designed to decouple user identity from message traffic, enabling you to perform customer verification, onboarding, and communications without storing full phone numbers in your systems. In practice, this means short-term, masked identifiers, encrypted transit, and restricted retention windows aligned with business needs and regulatory requirements.

How the Service Works: Technical Overview

The service operates as a managed layer that bridges your application with a pool of virtual numbers. Key elements include number provisioning, message routing, and event notification via webhooks. When you request a temporary number, the system allocates a shadow channel from a pooled set, associates it with your client context, and returns the number to your application. All inbound messages from end users are routed through our platform and then delivered to your webhook or API endpoint, with the original content subject to masking as configured by your policy.

For testing and validation, you can use the dedicated test workflow, sometimes involving the shortcode24255 textas a frictionless signal to verify channel viability. This capability helps you validate end-to-end routing, latency, and delivery confirmation without exposing real user data. The platform supports RESTful API endpoints for provisioning (/numbers), sending and receiving messages (/messages), and webhook callbacks (/webhooks). These endpoints are documented in our API reference and are designed to be integrated with modern CI/CD pipelines and DevOps practices.

Security Architecture and Encryption

Security is embedded at every layer. Data in transit uses TLS 1.2/1.3 with perfect forward secrecy. At rest, sensitive data is encrypted with AES-256, and keys are managed through a centralized, auditable Key Management Service (KMS). Access to the console, APIs, and logs is protected by multi-factor authentication (MFA), IP allowlisting, and role-based access control (RBAC). Audit logs capture user actions, API calls, and number provisioning events to support compliance reporting and incident investigations.

To further enhance privacy, we employ data minimization in message storage: only the minimum necessary metadata is stored, and message bodies are retained only as long as required by your retention policy. Anonymization and redaction rules can be configured to ensure that customer data never appears in internal dashboards or non-secure channels. Our infrastructure, including the PlastinkaCo backend, is designed for resilience, with redundant regions, automated failover, and continuous monitoring to minimize exposure to data leaks or service disruption.

Data Retention, Anonymization, and Deletion

Retention policies are defined by your organization’s data governance framework and compliant with applicable regulations (for example, GDPR and CCPA where relevant). Temporary numbers themselves are ephemeral by design. Message content is stored only as long as it is necessary for delivery confirmation, analytics, or required business purposes. When a temporary number is released, associated metadata is scrubbed or anonymized in accordance with your policy. You can configure automatic rotation, manual release, or policy-driven expiry to ensure numbers are not held longer than needed. Periodic purging processes run during maintenance windows to minimize operational impact.

Integration and Operational Guidance

Business integrations should be built around a stable API contract. Use cases commonly include user verification, login flows, customer support channels, marketing campaigns, and supplier onboarding. Our platform supports native connectors to the yodayo ecosystem, enabling streamlined workflow orchestration between verification, anti-fraud, and communications layers. When designing your integration, consider the following best practices:

• Prefer short-lived numbers for verification flows to reduce data exposure.
• Implement idempotent provisioning to avoid duplicate numbers on retries or outages.
• Validate inbound messages with digital signatures or per-channel tokens to prevent spoofing.
• Use webhooks with retry policies and scalable queues to handle bursts in message traffic.
• Leverage event types such as number_assigned, inbound_message, outbound_status, and number_released for robust state tracking.

Technically, we recommend a microservices approach with clear isolation between the messaging layer and business logic. The PlastinkaCo platform provides scalable backends and a robust API surface. On top of this, yodayo connectors help bridge with your preferred tooling, enabling enterprise-grade orchestration, analytics, and governance across the SMS lifecycle.

Usage Rules: Acceptable Use and Prohibited Actions

To maintain trust and safety, the following rules apply to all customers. Violations may result in suspension or termination of access with or without notice. These rules are designed to prevent abuse, protect privacy, and comply with legal obligations:

• Do not use temporary numbers to impersonate individuals, conduct fraud, or facilitate illegal activities.
• Do not store full phone numbers in customer databases beyond what's strictly necessary for business operations and in line with your retention policy.
• Avoid bulk or automated messaging that could degrade service quality or trigger anti-spam controls without user consent.
• Do not attempt to bypass masking, logging, or privacy controls; respect data minimization and request-for-access protocols.
• Adhere to applicable communications regulations, such as opt-in/opt-out requirements and regional data transfer rules.
• Do not export or route messages through untrusted third parties without appropriate security controls and data processing agreements.

We support strict rate limiting and anomaly detection. If traffic patterns resemble abuse, the system may throttle or suspend provisioning to protect overall service integrity and other customers. You may request adjustments to rate limits through your account manager, subject to security review and compliance checks.

Developer Guidance and SLA Expectations

Developers should rely on the documented API contracts, use proper authentication and key management, and implement robust error handling. Our service level agreement (SLA) covers availability, incident response, and support response times. Typical uptime targets are aligned with enterprise expectations, with maintenance windows communicated in advance. In the event of a service disruption, we provide status dashboards, incident communications, and post-mortem reports to ensure transparency and continuous improvement.

Privacy Management and Third-Party Sharing

Transparency and control over data flows are central to our privacy model. We minimize the personal data processed by the service and offer options for data localization, pseudonymization, and restricted visibility of message content in analytics views. If you require third-party audits or certifications, we can coordinate with independent assessors to verify our security controls. Any sharing of data with third parties is governed by data processing agreements and is restricted to what is necessary to operate the service, with safeguards around data minimization and purpose limitation.

Operational Resilience and Monitoring

Resilience is built into the cloud architecture, with multi-region deployments, automated failover, and continuous monitoring. We provide health checks, latency metrics, and alerting for key service components such as number provisioning, routing, webhooks, and storage. Regular penetration testing, vulnerability scanning, and security reviews are part of our maintenance routine. We encourage customers to implement their own monitoring on top of the platform to ensure visibility into their own usage patterns and any anomalies that may indicate misconfiguration or abuse.

Compliance and Legal Considerations

We align with applicable data protection and privacy laws, including GDPR and regional equivalents. Our retention, deletion, and data handling practices are designed to support lawful processing, data subject rights requests, and incident reporting requirements. If you operate in multiple jurisdictions, you can configure region-specific data handling rules and localization settings to meet local legal obligations while preserving overall privacy guarantees.

Operational Readiness: Onboarding and Support

New customers go through a structured onboarding process, including identity verification, environment provisioning, and initial policy configuration. Training materials and API documentation are provided to accelerate productive use. Our support team offers proactive guidance on best practices for privacy, security, and reliability. For critical deployments, you can request dedicated support and a named technical account manager to align with your governance framework.

Evidence of Compliance and Reporting

You will receive periodic reports on security events, data processing activities, and system performance. We provide access to audit-ready logs and compliance artifacts to simplify regulatory reporting and internal governance reviews. If you operate under a formal privacy program, you can map our data flows to your Data Inventory, Data Map, and DPIA (Data Protection Impact Assessment) workflows.

Transition, Termination, and Data Liberation

When you decide to discontinue use, you can terminate provisioning per your contractual terms. We offer data export and secure deletion options, ensuring that temporary numbers, logs, and metadata are removed in accordance with your retention policy. If you require an orderly wind-down, we provide a transition plan to minimize disruption to your operations and protect customer privacy throughout the migration.
