Privacy Policy

Logos is a personal AI wellness and planning assistant. This policy explains what information Logos handles, how it is used, and the choices you have.

Information We Collect

Account information may include your email address, Supabase user identifier, sign-in provider, subscription status, and operational account records. If you choose to subscribe, Stripe handles payment details and provides Logos with billing status, customer identifiers, and receipt-related metadata.

With your permission, the iOS app can read selected Apple Health, Calendar, Reminders, Location, Microphone, and Speech Recognition data. Health, calendar, reminder, speech, and local wellness summaries are used to provide app features you request.

If you connect Gmail or Google Calendar, Logos uses Pipedream to manage the separate Google authorization grants. OAuth tokens remain with Pipedream. Logos receives connected-account metadata and, for Google Calendar, the calendar and event fields needed to produce the read-only planning summary you request. This connection does not give the iOS app an inbox or email-reading feature.

How Logos Uses Information

Logos uses information to authenticate your account, run requested assistant features, maintain subscription access, sync supported account data, prevent abuse, debug service issues, and respond to support requests.

Cloud AI And Third-Party Processing

Logos does not send your personal data for Cloud AI processing until you give permission in the app. Before the first send, Logos identifies the information included in the request, names the recipients, and asks you to choose whether to send it.

Depending on the feature you request and the permissions you grant, the information sent may include:

• Your messages and prompts;
• HealthKit summary metrics you select;
• Native or connected Google Calendar and Reminders summaries you select;
• Approximate location context when relevant to your request;
• Saved responses, check-ins, or memory facts when those features are enabled; and
• Account identifiers and request metadata needed to authenticate, secure, and operate the service.

This information is sent first to the Logos backend and then to OpenAI, our third-party AI processor. OpenAI processes the information to generate the AI response you requested. Logos may also retain operational logs needed to secure, troubleshoot, and maintain the service. Logos does not use this information for advertising and does not sell it.

You can review private context before sending it, allow future sends for selected context types, or decline to send it. You can revoke a previous permission, turn off Cloud AI sharing, or disable Cloud AI at any time in the app's Privacy settings. Turning off Cloud AI prevents new assistant requests and their associated context from being sent to the Logos backend or OpenAI; supported local features remain available.

OpenAI and our other service providers process information only to provide services to Logos and are required by contract to protect it with the same or an equivalent level of privacy protection.

Health And Sensitive Data

Logos uses HealthKit data only to provide user-facing wellness summaries and assistant context. Logos does not use HealthKit data for advertising, marketing, use-based data mining, or sale to data brokers. Logos is not a medical device and does not provide diagnosis, treatment, emergency support, or clinical monitoring.

Sharing

Logos uses service providers for authentication, hosting, connected Google account authorization, payments, email delivery, analytics or operational logs, and AI processing. AI processing is provided by OpenAI. Payment processing is provided by Apple In-App Purchase on iOS and by Stripe for web subscriptions. These providers process data so Logos can operate the service and are required to protect that data under terms that provide the same or equal protection. We do not sell personal information.

Retention And Controls

You can export local app data, delete local analysis history, delete local wellness history, reset local state, sign out, and request account deletion from the app. Account deletion removes Logos backend account data associated with your Supabase account where supported. Stripe records may be retained for billing, tax, receipt, dispute, fraud prevention, and compliance obligations.

Children

Logos is not intended for children under 13. If you believe a child has provided personal information, contact us so we can review and delete it where required.

Changes

We may update this policy as Logos changes. The effective date above shows when this policy was last updated.
