Shannon

Privacy Policy

Last updated: May 30, 2026

This document is provided for informational purposes. Professional legal review is recommended.

Your trust is the foundation of Shannon. Shannon is provided by Cluesmith LLC ('we,' 'us,' 'our'). This policy explains what data we collect, why, what we do with it, and what we will never do with it. We wrote it to be read by humans, not lawyers.

The Short Version

  • We access your data only to provide Shannon's services to you.
  • We will never sell your personal data to anyone. Ever.
  • We share data with a small number of service providers (listed below) only as needed to deliver Shannon. They are contractually bound to protect your data.
  • We will never use your personal content (emails, messages, calendar entries) to train AI models without your explicit opt-in consent. We may use anonymized usage patterns to improve Shannon's reliability and features — you can opt out of this at any time. When the team needs to look at specific personal data to fix a bug or resolve a support issue, we do that under strict access controls described in §5, not as 'training' or 'improvement.'
  • Any Shannon team member who accesses user data does so under strict controls with a documented reason.
  • You can export or delete all your data at any time.

1. Information We Collect

Account Information. Your name and email address when you create an account.

Connected Service Data. When you connect services (including but not limited to Gmail, Google Calendar, Google Drive, WhatsApp), Shannon accesses the data you explicitly authorize via OAuth. You choose which services to connect, and you can disconnect any service at any time. When you disconnect a service, Shannon stops accessing that data immediately.

Conversation Data. Your conversations with Shannon, including questions, requests, and Shannon's responses.

Derived Data. Information Shannon creates based on your data. This includes task lists, contact profiles, project summaries, and morning briefings. This data belongs to you.

Usage Data. Technical information about how you use Shannon: device type, session duration, features used, and error logs. This does not include the content of your emails, messages, or conversations.

Information About Third Parties. Shannon may encounter information about other people in your emails, messages, and calendar entries — including family members, friends, colleagues, and others who communicate with you. Shannon may also build context about these individuals within your account to provide its services — for example, remembering a colleague's contact details, a friend's birthday, or a child's school and dietary needs. This context exists solely within your account, under your control, and is deleted when you delete your account or when you ask Shannon to remove it. Shannon does not contact third parties directly and does not use third-party information for any purpose other than assisting you. We treat all third-party information with the same security and deletion protections described in this policy. If you have concerns about third-party information that Shannon has processed, you can ask Shannon to remove it at any time.

2. How We Use Your Information

We use your data for the following specific purposes:

Purpose Data Used Legal Basis
Deliver Shannon's core services (email scanning, calendar management, task tracking, briefings) Connected service data, conversation data, derived data Contract performance
Respond to your support requests Account info, conversation data Contract performance
Send you service communications (briefings, alerts) Account info, connected service data Contract performance
Detect and prevent fraud or abuse Account info, usage data Legitimate interest
Improve Shannon's reliability and fix bugs Usage data, error logs (not personal content) Legitimate interest
Improve Shannon's features and user experience Anonymized, aggregated usage patterns only Legitimate interest (with opt-out available)

3. What we do NOT do

  • We do not sell your data to third parties.
  • We do not use your personal content (emails, messages, calendar) to train AI models without your explicit consent.
  • We do not show you ads or share data with advertisers.
  • We do not build profiles of you for any purpose other than delivering Shannon's services to you.

4. Service Providers (Sub-Processors)

Shannon works with a small number of service providers to deliver your experience. Each is held to strict privacy and security standards.

Provider Purpose Data Shared
Anthropic AI language model that powers Shannon's responses Your conversations and connected data are sent to Anthropic's API to generate responses. Anthropic's commercial API terms prohibit use of customer data for model training. When you delete your Shannon account, we stop sending data to Anthropic. Data previously processed by Anthropic is subject to Anthropic's own data retention practices. See Anthropic's commercial customer privacy policy for current data handling details.
Fly.io Cloud hosting infrastructure All Shannon data is hosted on Fly.io's US infrastructure. See Fly.io's security practices for current certifications and encryption details.
Resend Email delivery (briefings, alerts) Your email address and briefing content. See Resend's privacy policy and DPA.
Composio Service integrations (OAuth connections) OAuth tokens for connected services. Composio facilitates the secure connection between Shannon and your services (Gmail, Google Calendar, etc.) but does not access or store the content of those services. See Composio's privacy policy.
PostHog Product analytics Usage patterns, feature interactions, session data. Does not include personal content. See PostHog's privacy policy.

We select service providers that meet our security and privacy standards. We may add service providers as Shannon develops. If we add a new provider that handles your personal data, we will update this policy. Providers' specific practices may change over time. We link to their current policies above rather than restating them, so you always have the most up-to-date information. We review our service providers' privacy practices periodically. If we become aware of changes that materially reduce protection of your data, we will evaluate alternatives.

5. Employee Access to Your Data

We take this seriously. Here is exactly how it works:

  • No Shannon team member has routine access to your personal data. Access is granted only when required for a specific, documented reason (e.g., resolving a support request you initiated, investigating a system error).
  • Confidentiality agreements. Every team member and contractor who could access personal data has signed a binding confidentiality agreement.
  • Access is documented. We maintain a record of who on our team can access user data and why.
  • Access is limited. Only team members whose role requires it can access user data, and only for the purpose of providing and improving the service.

6. Data Used to Improve Shannon

We want to be transparent about this because it matters.

We treat 'training the AI model' and 'improving the product' as separate things, with separate rules.

What we use without asking: Anonymized, aggregated usage patterns — for example, "40% of users set up morning briefings in their first week" or "email scanning takes an average of 3 seconds." This data cannot be traced back to any individual.

What we will never use without your explicit consent: Your actual emails, messages, conversations, calendar entries, or any personal content. If we ever want to use personal content to improve Shannon (for example, to fine-tune how Shannon prioritizes emails), we will ask you first with a clear explanation of what, why, and how. You can say no, and it will not affect your service.

Technical safeguards: Before any data enters an analytics or improvement pipeline, it passes through an anonymization process that strips all personal identifiers. We use aggregation thresholds to ensure no individual's data can be reverse-engineered from aggregate statistics.

7. Google API Data Compliance

Shannon accesses Google user data (Gmail, Google Calendar, Google Drive) through authorized OAuth connections. Our use and transfer of information received from Google APIs to any other app will adhere to Google API Services User Data Policy, including the Limited Use requirements. Specifically: we only use Google API data to provide and improve Shannon's services to you; we do not use Google API data for serving advertisements; and we do not transfer Google API data to third parties except as necessary to provide Shannon's services, as required by law, or with your explicit consent. The use of 'improve' in this section refers to operational improvements to Shannon's services. See Section 6 for our separate rules on how data may or may not be used for AI training or product development.

Interim Integration Note: Google API connections are currently brokered securely via our infrastructure partner, Composio. The following scope table describes the direct-authorization model currently being rolled out across our platform.

Google scopes Shannon requests and what each one powers:

Scope What Shannon does with it
gmail.send Send emails on your behalf when you ask (you review and approve each draft first).
gmail.readonly Summarize incoming mail and surface what needs your attention in your briefing.
gmail.modify Apply labels, archive, and mark read when you ask Shannon to organize your inbox (never permanent delete).
calendar.events Create, update, and look up calendar events you ask about.
contacts.readonly Resolve names you mention ("email Sarah") to the right saved Google contact.
contacts.other.readonly Also resolve people you've corresponded with but never explicitly saved (Google "Other contacts").
drive.file Save files Shannon creates at your request and list those app-created files — never your existing Drive.
drive.readonly When you reference a Drive file, find and read it — including extracting text from uploaded documents (PDF / Word / Excel) — so Shannon can summarize, search, or answer questions about it.

Human Review Restrictions: There is no human review of Google API data by our personnel, except under the strict internal access controls and troubleshooting protocols described in Section 5 of this policy.

8. Your Rights

You have the following rights over your data, regardless of where you live.

  • Access: Request a copy of all personal data we hold about you.
  • Correction: Request correction of inaccurate data.
  • Deletion: Request deletion of your account and all associated data. We will complete deletion within 30 days.
  • Export: Download your data in a portable, machine-readable format.

To exercise any of these rights, contact us at [email protected].

9. Data Retention

  • Active account: Your data is retained as long as your account is active.
  • Deleted account: All personal data is deleted within 30 days of account deletion. Primary deletion (database rows, agent runtime, persistent storage volume) happens within 24 hours of your request. Encrypted infrastructure backup snapshots, retained for operational recovery, age out automatically over the following two weeks. After 30 days no copy of your account data remains in our systems.
  • Anonymized data: Retained indefinitely (since it cannot identify you and cannot be re-identified).
  • Connected service data: When you disconnect a service, Shannon stops accessing that service immediately and revokes our access at the third-party provider where the provider supports it (e.g., Google's OAuth revoke endpoint). Cached data from that service is deleted within 30 days using the same primary-then-backup-aging timeline as account deletion.

10. Cookies

Shannon uses session cookies to keep you logged in and analytics cookies via PostHog to understand how people use Shannon. We use PostHog to track usage patterns such as features used, session length, and navigation flows. PostHog does not track your personal content (emails, messages, calendar entries). We do not use advertising cookies or share analytics data with advertisers. By using Shannon, you consent to the use of session and analytics cookies as described above.

11. Children's Privacy

Shannon is designed for adults and we do not knowingly allow anyone under 18 to create an account. However, Shannon may process information about children when it appears in a user's emails, messages, or calendar entries, for example, school communications, medical appointments, or messages from family members. Shannon may also build context about children within a user's account to provide its services, for example, remembering a child's school, doctor, or dietary needs. This context exists solely within the account holder's control, is subject to the same security and deletion protections described in this policy, and is permanently deleted when the account holder deletes their account.

12. International Data Transfers

Shannon's infrastructure is hosted in the United States via Fly.io. If you are located outside the United States, your data will be transferred to and processed in the US. For users in the European Economic Area or UK, we will put appropriate transfer mechanisms in place, including Standard Contractual Clauses, as required by applicable law.

13. Security

  • All data is encrypted in transit using TLS.
  • OAuth tokens (access + refresh) are encrypted at rest using XChaCha20-Poly1305 with versioned key rotation, so we can rotate encryption keys without downtime or re-encryption migrations.
  • Each user's compute environment runs in an isolated Firecracker microVM with its own dedicated persistent storage volume. Cross-user data access is structurally impossible.
  • Authentication uses signed JWTs verified against a published JWKS keyset.
  • We conduct security reviews as part of our development process.
  • In the event of a data breach affecting your personal information, we will notify you within 72 hours of becoming aware of it, in accordance with applicable law.

14. California Residents (CCPA/CPRA)

If you are a California resident, you have additional rights under the California Consumer Privacy Act:

  • Right to know what personal information we collect, use, and share.
  • Right to delete your personal information.
  • Right to opt out of the sale of personal information. We do not sell your personal information.
  • Right to limit the use and disclosure of sensitive personal information. You can request that we limit our use and disclosure of sensitive personal information (such as the contents of your emails, messages, and calendar entries) to what is necessary to deliver Shannon's services to you.
  • Non-discrimination. We will not treat you differently for exercising your privacy rights.
  • To exercise any of these rights, contact us at [email protected].

15. European Residents (GDPR)

If you are in the European Economic Area or UK:

  • Our lawful bases for processing are contract performance (to deliver Shannon) and legitimate interest (for security and product improvement using anonymized data).
  • You may contact our Data Protection contact at [email protected].
  • You may ask us to limit how we use your data.
  • You have the right to lodge a complaint with your local supervisory authority.
  • Cross-border data transfers are governed by Standard Contractual Clauses.
  • You may object to any processing based on legitimate interest.
  • If you opted in to use of your personal content for product improvement (e.g., fine-tuning), you can opt out at any time.

16. Governing Law

This Privacy Policy is governed by the laws of the State of California, United States. Any disputes arising from this policy will be resolved in the state or federal courts located in California. This choice of law does not limit your statutory privacy rights under GDPR, CCPA, or other applicable local laws.

17. Changes to This Policy

We may update this policy from time to time. Changes will be posted on our website with an updated effective date. For material changes that affect how we collect, use, or share your personal data, we will notify you by email at least 7 days before the change takes effect. Your continued use of Shannon after the effective date constitutes acceptance of the updated policy. We will never retroactively reduce your privacy protections without your consent.
