Privacy Policy

Kin AI is operated by Kin Technologies LLC (“Kin,” “we,” “us,” or “our”). This Privacy Policy explains how we collect, use, disclose, and protect information about you when you use our website (kinai.family), text messaging service, and related services (collectively, the “Service”).

Questions? Contact us at hello@kinai.family.

Account information. When you create an account, we collect your name, email address, and any profile information you provide.

Calendar data. With your explicit permission, we access your Google Calendar with read-only permission. We read your calendar to understand your schedule and build your briefings — Kin never writes to, modifies, or deletes events on your calendar. We do not access your calendar without your consent.

Household data. You may optionally add information about your household including partner details, children's names, ages, and activities, and other family members. This information is used only to personalize your Kin experience.

Usage data. We automatically collect information about how you use the Service, including features accessed, interactions with Kin's AI, session data, and diagnostic information.

Device information. We collect device type, operating system, and browser version to provide support and improve the Service.

Payment information. Subscription billing is handled entirely by Stripe. Payment card details are collected and stored by Stripe — we never see or store your full card number.

We use the information we collect to:

• Provide, operate, and improve the Kin AI service
• Generate personalized family schedule briefings and reminders
• Detect scheduling conflicts and notify you proactively
• Sync and manage your calendar events with your permission
• Process your subscription and manage billing
• Send important service communications
• Respond to support requests
• Detect and prevent fraud, abuse, and security issues
• Comply with legal obligations

We do not sell your personal information to third parties. We do not use your calendar data for advertising purposes.

Kin AI uses artificial intelligence to analyze your calendar, generate briefings, and provide scheduling insights. This processing is performed using Anthropic's Claude AI platform. Your calendar data and household context may be sent to Anthropic to generate AI responses on your behalf.

Anthropic processes data under data processing agreements that restrict the use of your data for model training. For Anthropic's privacy practices, see anthropic.com/privacy.

We minimize the data sent to AI systems — only the information necessary to answer your query or generate your briefing is transmitted.

We share your data with the following service providers:

• Supabase — database and authentication infrastructure. Data stored in the United States.
• Vercel — application hosting and edge network. Request metadata (IP, user-agent) is processed at the edge; no application data is stored beyond standard server logs.
• Google — calendar access via Google OAuth. Subject to Google's Privacy Policy.
• Anthropic — AI inference for generating schedule briefings and insights.
• Stripe — subscription billing via Stripe Checkout and the Stripe Customer Portal. Payment card data is collected and stored by Stripe; we never see or store full card numbers.
• Twilio — SMS delivery for your morning briefing and reminders.
• Resend — transactional email delivery (account, billing, and support emails).
• Slack — operational alerts to our team about service health.
• Sentry — error tracking and crash reporting. Anonymized diagnostic data only.

We may also disclose your information if required by law, to protect the safety of our users, or in connection with a merger or acquisition (in which case you will be notified).

Consent. By submitting your phone number to Kin's waitlist or onboarding flow you consent to receive recurring automated SMS messages from Kin including a daily morning briefing, pickup-risk alerts, weekly check-ins, and transactional account messages.

Frequency. Typically one morning briefing per day plus occasional alerts and weekly check-ins. Frequency varies with your household's schedule.

Carrier charges. Message and data rates may apply. Kin does not charge for SMS; your carrier may.

Opt-out (STOP). Reply STOP to any Kin message at any time to immediately unsubscribe. You will receive one final confirmation message and no further automated SMS thereafter.

Help (HELP). Reply HELP to any Kin message for assistance, or email hello@kinai.family.

Carrier support. Kin's A2P 10DLC SMS program is delivered via Twilio. Supported carriers include AT&T, Verizon, T-Mobile, and most other US/Canada carriers. Delivery is not guaranteed during carrier outages.

Kin requests access to your Google Calendar using OAuth 2.0. We request read-only access to view your schedule. Kin never writes to, modifies, or deletes events on your calendar.

Scope of use: We access only the calendars you authorize during setup. We do not share your calendar data with other users except your connected household partner(s).

You can revoke Kin's access to your Google Calendar at any time from your Google Account settings at myaccount.google.com/permissions.

Kin's use of Google user data complies with the Google API Services User Data Policy, including the Limited Use requirements.

We retain your account and calendar data for as long as your account is active. If you delete your account, we will delete your personal data within 30 days, except where retention is required by law.

AI interaction logs may be retained in anonymized or aggregated form for up to 12 months to improve our service.

Access and correction. You can view and update your account information in your dashboard at any time.

Deletion. To delete your account, email hello@kinai.family with the subject “Delete my account” from the email address on file. We will permanently remove your profile, household data, and calendar access within 30 days.

Subscription management. You can manage or cancel your subscription at any time from /dashboard/billing, which opens the Stripe Customer Portal.

Data export. You may request a copy of your data by contacting us at hello@kinai.family. We will provide your data in a machine-readable format within 30 days.

Calendar access. You can revoke Google Calendar access without deleting your account. Some features will be unavailable without calendar access.

Our legal basis for processing: (a) contract performance — to provide the service; (b) legitimate interests — to improve and secure the service; (c) consent — for Google Calendar access. To exercise rights, contact hello@kinai.family.

California residents have rights under the CCPA, as amended by the CPRA:

• Right to know what personal information we collect, use, disclose, and sell

Kin is designed for use by adults managing family schedules. The Service is not directed to children under 13. We do not knowingly collect personal information from children under 13.

Parents may enter information about their children (such as names and activities) as part of managing household schedules. This data is managed by the adult account holder.

We implement encryption in transit (TLS 1.2+), AES-256 encryption at rest via Supabase Postgres for all database storage, access controls, and security monitoring to protect your data. We use Sentry for error tracking to identify and respond to issues promptly; Sentry events are scrubbed of personal identifiers (phone, email, names, IDs) before transmission.

If you discover a security vulnerability, contact hello@kinai.family.

We may update this Privacy Policy from time to time. We will notify you of material changes by posting the updated policy on the website and, where required by law, by email.
