Privacy Policy

1. Introduction

Human Interface Design LLC ("Company," "we," "us," or "our"), doing business as OS1, operates the OS1 mobile application and the website OS1.computer (collectively, the "Service"). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our Service.

OS1 is designed to feel personal without making privacy feel mysterious. We process your chats and attachments to provide AI responses, offer optional memory, sync conversations through your personal iCloud account when enabled, and collect limited analytics and diagnostics so we can keep the product reliable.

Our principal place of business is 418 Broadway, Ste N, Albany, New York 12207. You can contact us at legal@hi.OS1.computer.

2. Information We Collect

Information You Provide

We collect information you provide or generate when using the Service, including:

• Name, email address, and support messages you send us
• User-generated content, including prompts, messages, images, files, and outputs
• Authentication tokens used to keep you signed in
• Apple Push Notification tokens, if you opt in to notifications
• Feature preferences you set in the app, such as memory, iCloud sync, health-data, finance-data, location, and prompt-suggestion settings
• Signals used to verify legitimate devices and detect abuse, fraud, or automated traffic, including device integrity and account-status signals

Subscriptions and Billing

Subscriptions and paid features may be sold through Apple In-App Purchase, Stripe, or other payment processors we support. Payment processors handle payment details such as card numbers; we receive and store purchase and subscription records needed to provide the Service, such as product and transaction identifiers, receipt or checkout payloads, processor customer identifiers, subscription status, renewal status, refund status, and period start/end dates. We also maintain a credit ledger associated with your account.

Memory

Memory is optional and can be enabled or disabled in the app. When memory is enabled, OS1 may extract short, durable details from your conversations, such as preferences, ongoing projects, relationships, or standing instructions, and store them separately from your chat history to personalize future responses. Memory is not intended for secrets, credentials, payment data, exact addresses, health data, or other highly sensitive details. If memory is disabled, OS1 does not recall or save memories for that request. You can review and delete saved memories in the app.

Generated Media

When you generate images or video, we store the generated media or links to it, the prompt and parameters used to generate it, the underlying model identifier, and related metadata so the media can be displayed in your conversation and recovered if a generation continues after your app disconnects.

Automatically Collected Information

When you access the Service, we may automatically collect:

• Device information, such as device type, operating system, and app version
• Usage data, such as features used, interaction events, timestamps, and settings
• Log data, such as IP address, browser type, request metadata, and pages visited
• Crash and diagnostics data, such as crash traces, performance data, device state, and error metadata

We use self-hosted or controlled analytics and diagnostics where practical. Analytics events help us understand product usage at a high level. Crash and diagnostics data help us fix bugs. We do not use these tools to read your private conversations for advertising.

Waitlist and Marketing

If you sign up for our website waitlist, you voluntarily provide your email address, which we use to send product updates about OS1. Waitlist emails are processed by an email-delivery provider on our behalf and are not necessarily linked to an in-app account.

3. How We Use Your Information

We use the information we collect to:

• Provide, maintain, personalize, and improve the Service
• Process subscriptions, credits, and account entitlements
• Generate AI responses and media using the models and tools available in OS1
• Enable optional features, such as memory, iCloud sync, notifications, and tools
• Send administrative information, updates, and security alerts
• Respond to comments, questions, and support requests
• Monitor usage trends and product quality
• Detect, prevent, and address technical issues, fraud, abuse, and safety risks
• Suspend, restrict, or terminate abusive accounts or devices
• Comply with legal obligations

4. Local Storage, iCloud, and Conversations

The OS1 mobile application stores conversation history locally on your device. If iCloud sync is enabled, your conversations and related local app data may also be stored in your personal iCloud account using Apple's CloudKit infrastructure. iCloud storage is controlled by your Apple account and governed by Apple's privacy policy and terms.

Your messages, attachments, tool results, and related metadata pass through our servers and the underlying providers we use in order to provide responses, use tools, process uploads, generate media, enforce safety rules, and operate the Service. We store server-side data where needed to provide the Service, including account and authentication state, push and preference settings, subscription and credit data, memories if enabled, generated media, media jobs, and related operational metadata.

5. Infrastructure and AI Providers

OS1 relies on infrastructure and service providers, including providers of cloud hosting, storage, content delivery, language-model inference, image and video generation, web and other search, analytics, diagnostics, push notifications, email delivery, fraud and abuse prevention, and Apple platform services.

When you use the Service, your inputs and outputs may be transmitted to and processed by the relevant providers as needed to fulfill your request. Where commercially reasonable, we configure model providers not to train on your data, including through provider settings that disallow prompt training when available. We cannot guarantee every third party's independent data-handling practices, and each provider's own terms and policies may also apply.

The Service is not a marketplace or selector for underlying providers. We may add, remove, or replace providers and models as the Service evolves.

6. Data Retention

We retain personal information for as long as reasonably necessary to provide and improve the Service, maintain your account, comply with legal and platform obligations, resolve disputes, prevent abuse, and enforce our agreements. Different categories of data may have different retention periods.

You may request deletion of personal information by contacting us at legal@hi.OS1.computer. We may retain certain information for a limited period after a deletion request where needed for security, fraud prevention, legal compliance, billing records, backups, dispute resolution, or enforcement of our terms. We may retain aggregated or de-identified information in a form that does not identify you.

7. Data Sharing and Disclosure

We may share, disclose, or transfer information in the following circumstances:

• Service Providers: With vendors who perform services on our behalf, including hosting, storage, model inference, content generation, search, payment, analytics, diagnostics, push notifications, email delivery, and fraud prevention
• AI and Tool Providers: With model, media-generation, search, maps, music, weather, finance, or other providers as needed to fulfill requests you make through the Service
• Affiliates: With our current or future affiliates, parents, or subsidiaries for purposes consistent with this Privacy Policy
• Legal and Safety: If required by law, regulation, legal process, or governmental request, or when reasonably necessary to protect rights, safety, security, or the integrity of the Service
• Business Transfers: In connection with a merger, acquisition, financing, reorganization, bankruptcy, sale of assets or equity, or similar transaction, including diligence related to that transaction
• With Your Direction or Consent: When you direct us to share information or otherwise consent to sharing
• Aggregated or De-identified Data: We may use and share aggregated, anonymized, or de-identified data for analytics, research, model evaluation, benchmarking, product development, and similar purposes

We do not sell your private conversation content to data brokers or use it for cross-context behavioral advertising. If applicable law gives you a right to opt out of certain sharing, sales, or targeted advertising, you may exercise that right by contacting us as described below.

8. Data Security

We implement commercially reasonable technical and organizational measures to protect your personal information. However, no method of transmission over the Internet or electronic storage is 100% secure. We cannot guarantee absolute security of your data.

9. Your Rights and Choices

Depending on your jurisdiction, you may have the right to:

• Access, correct, export, or delete your personal information
• Object to or restrict certain processing of your data
• Withdraw consent where processing is based on consent
• Opt out of certain sharing, sales, or targeted advertising where applicable

You can also control certain data uses directly in the app, including memory, iCloud sync, notifications, and optional data tools. Turning memory off stops OS1 from recalling or saving memories for new requests, but it does not automatically delete memories that were previously saved. You can delete saved memories in the app or contact us for help with broader account data requests.

To exercise privacy rights or ask questions, please contact us at legal@hi.OS1.computer.

10. Children's Privacy

The Service is not intended for children under 13 years of age. We do not knowingly collect personal information from children under 13. If we become aware that we have collected personal information from a child under 13, we will take steps to delete that information.

11. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Changes are effective when posted unless otherwise stated. If we make material changes, we will take reasonable steps to notify you, such as through the Service or by updating the date above.
