Privacy Policy
Last Updated: September 26, 2026
Syren is operated by Aurandel, PBC, a Delaware public benefit corporation (“Aurandel,” “Syren,” “we,” “us,” or “our”).
This Privacy Policy explains how we collect, use, disclose, protect, and retain information when you visit the Syren website, request access to Syren, communicate with us, or use the Syren service.
Syren is currently offered as a private, invite-only beta. This Privacy Policy does not promise anonymity, absolute confidentiality, or perfect security.
1. Information We Collect
Account information
When you create or use a Syren account, we may collect information such as:
- your email address;
- authentication credentials and related security information;
- invitation, verification, and account status;
- account settings and preferences; and
- information associated with account access, security, and administration.
Conversations and companion information
When you interact with Syren, we may process information that you provide or that is generated through your use of the service, including:
- conversation text;
- voice transcripts;
- conversation history;
- conversation summaries and session recaps;
- saved memories;
- information used to maintain conversation continuity and safety features;
- companion preferences;
- custom companion descriptions and instructions;
- information used to personalize future interactions; and
- technical representations derived from conversation information that help Syren retrieve relevant memories or context.
Because Syren is designed for personal and intimate conversation, information you choose to share may sometimes concern sensitive subjects, including relationships, sexuality, emotional experiences, health, beliefs, or other private matters.
You decide what you share with Syren. Please do not provide information about yourself or another person that you do not want processed as described in this Policy.
Voice information
If you use voice features, microphone audio is transmitted to Syren's backend and may be transmitted to a speech-recognition provider so that it can be transcribed.
Syren's current backend processes these audio uploads in memory and does not intentionally save the original microphone recording to Syren's persistent audio storage as part of ordinary transcription.
The resulting transcript may become part of your conversation history, memories, summaries, or other continuity information.
Third-party voice or transcription providers may process information according to their own systems, agreements, and retention practices.
Usage and technical information
We may collect operational information necessary to provide, secure, troubleshoot, and improve the service, such as:
- feature usage;
- request and response timing;
- token or provider usage;
- service costs;
- application events;
- device and browser information;
- security events;
- diagnostic and error information; and
- network-related information.
We design our application error logging to avoid intentionally recording conversation content. Technical systems and infrastructure providers may nevertheless process information necessary to operate, secure, diagnose, or deliver the service.
Invitations and communications
If you request an invitation, we may collect your email address and information associated with your request, including consent or submission timestamps. If you use the optional companion design preview, its name, selected traits, voice choice, and color stay in your browser until you submit an invitation request. Those four choices are then saved with that request.
If you contact us, we may collect your email address, your message, and related submission information.
Please do not include unnecessary sensitive information in general contact forms.
Security and abuse prevention
We may process network, device, account, or similar technical information to prevent abuse, fraud, unauthorized access, attacks, or other misuse.
Some anti-abuse systems may use hashed or otherwise transformed network identifiers.
Hosting, security, networking, and content-delivery providers may also generate and retain technical request or security logs.
2. How We Use Information
We may use information to:
- provide and operate Syren;
- create and authenticate accounts;
- generate AI responses;
- transcribe voice input and generate spoken responses;
- maintain conversation continuity;
- retrieve memories and preferences relevant to future conversations;
- personalize companion behavior at your direction;
- provide safety-related features;
- maintain, troubleshoot, and improve the service;
- monitor reliability, usage, performance, and costs;
- detect and prevent fraud, abuse, security incidents, or misuse;
- respond to support and privacy requests;
- administer the private beta;
- enforce our Terms and other policies;
- protect Syren, Aurandel, our users, and others; and
- comply with applicable law and lawful legal process.
We do not need access to the substance of conversations for routine administrative usage reporting.
3. AI, Voice, Hosting, and Other Service Providers
Syren relies on third-party and self-hosted systems to provide the service.
Depending on the feature you use, these currently include:
- a third-party AI model provider for conversation generation;
- a third-party speech-recognition provider for transcribing voice input;
- speech synthesis operated on Syren-controlled infrastructure, and a third-party voice provider for certain custom companion voices; and
- hosting, networking, security, email, and infrastructure providers necessary to operate Syren.
When necessary to perform a requested feature, Syren may transmit relevant information to these providers. For example:
- relevant conversation context may be transmitted to an AI provider;
- microphone audio may be transmitted to a transcription provider; and
- response text may be transmitted to a speech provider.
We seek to limit information sent to providers to what is reasonably necessary to provide the relevant service.
Third-party providers process information under their own contractual, technical, security, retention, and legal requirements. Their systems may retain information for periods that differ from Syren's own retention practices.
We therefore do not promise that information transmitted to a service provider is never retained, processed outside your jurisdiction, reviewed for permitted operational or safety purposes, or otherwise handled as permitted by that provider's applicable agreement and settings.
We may change service providers as Syren evolves. Where a change materially affects our privacy practices, we may update this Policy.
4. Encryption and Security
We use technical and organizational measures designed to protect information against unauthorized access, disclosure, alteration, or loss.
Syren encrypts certain server-stored information, including stored memories, session recaps, continuity information, custom companion information, and related stored metadata. These protections use account-specific cryptographic separation so that protected information associated with different accounts is not encrypted under one interchangeable account key.
We also use access controls and other safeguards intended to reduce unnecessary access to conversation information.
Privileged access to protected information is restricted and may be logged for security and accountability purposes.
Some information necessarily exists in unencrypted form while it is actively being processed—for example, while generating an AI response, transcribing speech, retrieving information for a conversation, or synthesizing speech.
Some information is also outside Syren's server-side content encryption, including:
- information stored locally on your device;
- mathematical vector representations used for memory retrieval;
- information while it is transmitted to or processed by service providers; and
- certain operational or infrastructure information.
Information is encrypted in transit where supported by the applicable service and infrastructure.
No security system can guarantee that information will never be accessed, disclosed, altered, or destroyed without authorization. Accordingly, we do not promise absolute security.
5. Information Stored on Your Device
Syren may store information locally on your device to provide application functionality.
Depending on the version of the application and features you use, this may include:
- sign-in or session information;
- application state;
- conversation history;
- conversation drafts;
- preferences; and
- cached application resources.
Information stored on your device is subject to the security of that device, browser, operating system, account, backups, and synchronization services you use.
Deleting information from Syren's servers does not necessarily delete a copy stored on your device or in a device or browser backup.
The Syren web application may use browser storage and a service worker to support application functionality and installed-app behavior.
6. Memories and Conversation Controls
Syren provides controls that allow you to inspect and remove certain saved memories through the Memory Vault.
Deleting a saved memory removes that memory from Syren's active memory system. However, the underlying information may still appear elsewhere—for example:
- in an earlier conversation;
- in a previously generated recap or summary;
- on your device;
- in a backup awaiting expiration; or
- in information previously transmitted to a service provider.
Deleting one representation of information therefore does not necessarily delete every other representation containing the same underlying information.
7. Account Deletion
You may delete your Syren account using the available in-app account deletion feature.
Account deletion is designed to remove the active account and associated live records controlled by Syren.
Deletion may not immediately remove information from:
- backups or disaster-recovery systems;
- system logs;
- information required for fraud prevention, security, legal compliance, dispute resolution, or enforcement;
- information stored locally on your device; or
- systems controlled by third-party service providers.
Residual information in backups may remain until those backups are overwritten, recycled, or expire under applicable operational processes.
We do not promise instantaneous deletion of every physical representation of information.
We may retain limited information when reasonably necessary to comply with law, protect the service or others, establish or defend legal claims, investigate misuse, or enforce our agreements.
8. Retention
We retain information for as long as reasonably necessary for the purposes described in this Policy, including providing the service, maintaining continuity requested by users, protecting security, resolving disputes, meeting legal obligations, and operating the service.
Different categories of information may be retained for different periods.
For information under your control, available deletion tools may allow you to remove particular information or your account sooner.
Backups, logs, and information held by service providers may follow separate lifecycle and retention processes.
As Syren's beta infrastructure and operational practices mature, we may adopt more specific retention periods and update this Policy accordingly.
9. Disclosure of Information
We may disclose information:
To service providers
We may provide information to companies that perform services on our behalf, such as AI processing, transcription, speech synthesis, hosting, networking, email delivery, security, infrastructure, and technical operations.
For safety, security, or legal reasons
We may preserve, use, or disclose information when we reasonably believe it is necessary to:
- comply with applicable law, regulation, court order, subpoena, or other lawful process;
- respond to a valid governmental or law-enforcement request;
- protect the rights, property, or safety of Aurandel, Syren, our users, or others;
- investigate fraud, abuse, security incidents, or violations of our policies; or
- establish, exercise, or defend legal claims.
Nothing in this Policy promises that communications are legally privileged.
Business transactions
If Aurandel is involved in a financing, merger, acquisition, restructuring, bankruptcy, asset transfer, or similar corporate transaction, information may be disclosed as reasonably necessary to evaluate or complete that transaction, subject to applicable law and appropriate confidentiality protections.
10. Sale and Advertising
Syren does not currently sell personal information for money.
Syren does not currently use conversation content to serve third-party behavioral advertisements.
If these practices materially change, we will update this Policy and provide any choices required by applicable law before applying the changed practice where required.
11. International Processing
Syren's providers and infrastructure may process information in jurisdictions different from the one in which you live.
Those jurisdictions may have privacy or data-protection laws that differ from the laws where you live.
By using features that require these providers, your information may be transmitted to and processed in those jurisdictions as necessary to provide the service, subject to applicable law.
12. Your Privacy Choices and Rights
Depending on where you live and the laws that apply to Syren, you may have rights concerning your personal information, such as the right to request:
- access to certain information;
- deletion;
- correction;
- information about how personal information is used or disclosed;
- a portable copy of certain information; or
- other rights provided by applicable law.
Not every right applies in every jurisdiction or circumstance, and lawful exceptions may apply.
We may need to verify your identity or account ownership before fulfilling a request.
You may use Syren's in-app controls where available or submit a privacy request through our contact form.
We will not discriminate against you for exercising privacy rights provided by applicable law.
13. Sensitive Information
Syren is designed for personal conversation. As a result, users may voluntarily provide information that applicable privacy laws consider sensitive.
You are not required to disclose sensitive information merely to create an account.
When sensitive information is voluntarily provided in a conversation, we process it as necessary to provide the interaction, continuity, memory, personalization, safety, or other functionality requested through the service and as otherwise described in this Policy.
Please consider carefully what you choose to share.
14. Adults Only
Syren is intended only for adults who are 18 years of age or older.
The public website does not itself grant access to the Syren application. During the private beta, application access requires an invitation and an approved account.
If we learn that an account is being used by someone under 18, we may restrict or terminate the account and take reasonable steps regarding associated information.
If you believe a person under 18 is using Syren, please contact us.
15. No Medical or Professional Confidentiality
Syren is an AI companion service. It is not a healthcare provider, therapist, physician, attorney, financial adviser, or other licensed professional.
Information you disclose to Syren is therefore not necessarily protected by professional privileges or confidentiality rules that apply to communications with licensed healthcare professionals, attorneys, or similar professionals.
Please use discretion when sharing highly sensitive information.
16. Changes to This Policy
Syren is an evolving beta service. Our features, providers, security practices, and infrastructure may change.
We may update this Privacy Policy from time to time to reflect changes to the service, our practices, legal requirements, or other circumstances.
When we make material changes, we may provide additional notice where appropriate or required by law.
The “Last Updated” date at the top identifies the most recent version.
