Privacy Policy

Last Updated: October 2, 2026

Welcome to Kasane! We are committed to protecting your privacy and handling your personal health information responsibly. This Privacy Policy explains how we collect, use, store, and share your information when you use the Kasane mobile application ("App"). Section 10 covers the Kasane 3.0 beta list on our website.

Your data lives on your device
All your data is stored on-device. If you use Sign in with Apple, it syncs to iCloud on Apple's servers. Our only server is a lightweight relay for AI requests — it doesn't log or store your data, and we never have access to your personal health information.
AI is core to Kasane
Kasane is built around AI-powered personalized behavior change. AI features cannot be disabled because they are fundamental to how the app works. If you are not comfortable with health context data being sent to Anthropic for processing, Kasane is not the right fit.
We send the minimum data necessary
We never send raw wearable streams, lab PDFs, or HealthKit records over the wire. Your health data is distilled on-device into brief context summaries — only what's needed to generate your personalized plan.
Anthropic does not train on your data
Data sent through Anthropic's API is not used for model training. They retain inputs and outputs for up to 7 days for safety monitoring, then permanently delete them.

1. Information We Collect

We collect information to provide and improve the App's features, particularly personalized habit guidance and Focus Plans. This includes:

Information You Provide Directly: Your Profile Information (name, date of birth, biological sex, health goals) and Health Context (exercise frequency, sleep habits, nutrition, stress levels, medical conditions, alcohol and tobacco use, family health history, and medications).

Habit and Check-In Data: Habits you create or accept, daily check-ins, streak data, graduation milestones, and voice check-in transcripts.

Information Generated by the App: Includes AI-Generated Content (personalized Focus Plans, habit suggestions, milestone celebrations, and check-in analysis based on your data).

2. How We Use Your Information

We use your data to:

Provide App functionality (display habits, track progress, manage check-ins).
Enable AI features (generate personalized Focus Plans, analyze check-ins, suggest habits).
Improve App usability and features.

3. Data Storage and Security

Local Storage: All data is stored locally on your device using Apple's CoreData framework.
iCloud Sync (Automatic): Your data syncs to your personal iCloud account via CloudKit, under Apple's control. Kasane does not operate its own servers for your personal data.
Security Measures: We implement industry-standard technical measures provided by iOS to secure your data; however, no system is 100% secure.
Data Retention: On-device data persists until you delete it (e.g., by removing habits, deleting your profile, or uninstalling the App). Kasane does not maintain a server-side copy of your personal or health data.

4. AI Processing and Our Proxy Server

Certain App features require sending data to Anthropic's Claude API for AI processing:

What is sent: To generate Focus Plans, habit suggestions, check-in analysis, and other AI features, we send relevant context which may include: profile information (age, sex), health context (exercise, sleep, nutrition, stress, medical conditions), habit data, and check-in content. Raw health data (wearable streams, lab documents, HealthKit records) is never sent directly — it is distilled on-device into brief context summaries containing only the minimum information needed to generate your personalized plan.
How it is sent: Requests pass through our proxy server (a Cloudflare Worker at api.kasanelife.com). This server exists solely to keep the API key server-side. Our proxy does not log, store, or inspect request or response content.
Anthropic's data handling: Anthropic does not train on data sent through their API. They retain API inputs and outputs for up to 7 days for safety monitoring, then delete them. Please review Anthropic's Privacy Policy and API Terms.

5. Subscription Billing (Inner Circle)

If you purchase an Inner Circle subscription, payment is processed by Apple through the App Store. Kasane does not receive your payment-method information. We receive an anonymous transaction identifier from Apple that confirms your active entitlement, used solely to unlock subscription features in the App. You can manage or cancel your subscription anytime in Settings → Apple ID → Subscriptions.

We do not sell your personal data. We will not share your information with other third parties unless required by law, to protect our rights, or in the event of a merger or acquisition (with prior notice).

6. Your Control and Choices

Access and Correction: Update your profile and manage habits directly in the App.
Data Deletion: Delete individual habits, check-ins, or your entire profile within the App. You can also delete your account in Settings, which removes all local data and all data stored in your iCloud account. Uninstalling the App removes all local data.
AI Features: AI features require the data described above to function. If you prefer not to send data to Anthropic, you may choose not to use AI-powered features (Focus Plans, voice check-ins, AI-generated suggestions).

7. Children's Privacy

The App is not directed to children under the age of 13. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact us so we can take appropriate action.

8. Changes to This Privacy Policy

We may update this Privacy Policy periodically. Significant changes will be communicated via the App or other methods. Continued use after updates constitutes acceptance of the new policy.

10. The Kasane 3.0 Beta List

This section covers the Kasane 3.0 beta signup form on kasanelife.com, operated by Enchant. Updated October 2, 2026.

What we save

Your email address, the signup time, and a record of your permission to receive Kasane beta invitations and updates. The form does not ask for health information.

Why we save it

So we can invite you to the beta and share updates about testing Kasane 3.0. When you join, Paul sends you a welcome email (reply to it and it reaches him), and he gets a note that you joined. Joining the list does not create an app account, start a subscription, or guarantee immediate beta access.

Where it goes

The list is stored in a private Cloudflare database in Enchant’s account. Our team can access it to manage beta invitations. There is no public endpoint for reading the list. Beta emails are sent through Cloudflare’s email service. This page does not record your form input in analytics or session recordings.

Keeping the form working

Cloudflare processes network information to serve requests. The signup service uses a short-lived hash derived from the connecting network address to limit repeated attempts. Its counters expire within 24 hours and are removed daily; the service does not store the raw network address in the beta list.

If you reply

Our welcome email asks a few questions you can answer by replying. Replies go to Paul’s inbox (paul@kasanelife.com, hosted by Google Workspace), and we read them to learn what families need from Kasane and to shape the beta. A reply may include health information about you or someone you care for, so share only what you’re comfortable with. Replies stay in that inbox; they aren’t added to the beta list or to any app account, and we don’t share them outside Enchant except with Google, which hosts the inbox. We delete your replies whenever you ask us to, and asking to leave the beta list counts as asking. Otherwise they stay in the inbox, including after an inactive signup expires from the list.

Changing your mind

Email pvm@enchant.co to ask us to remove your signup or correct your email. Signup records are removed after one year without a renewed signup. You can also ask to stop receiving beta emails whenever we contact you.

The beta app

This section covers the beta list only. Sections 1 to 9 cover the Kasane app, and its terms are on their own page. Review the privacy information supplied with your beta build before adding health information.

California Privacy Notice

Last Updated: October 2, 2026

This California Privacy Notice supplements the information in our Privacy Policy and applies solely to residents of California ("consumers" or "you"). We provide this notice to comply with the California Consumer Privacy Act of 2018 and the California Privacy Rights Act of 2020 ("California Privacy Law").

Any terms defined in California Privacy Law have the same meaning here.

Information We Collect

In the past 12 months we have collected the following categories of personal information:

Identifiers — device identifiers and email address when you contact support; email address, and the time and version of your consent, when you join the Kasane 3.0 beta list.
Personal information under Cal. Civ. Code § 1798.80(e) — name, date of birth, biological sex (when supplied by you).
Protected classification characteristics — age (derived from date of birth) and sex.
Commercial information — records of in-app subscriptions or purchases (if any).
Internet or similar network activity — limited, anonymized usage metrics describing your interaction with the App (only what is provided by Apple's App Store Connect); and, when you submit the beta signup form, a keyed hash of your network address, used only to limit repeated attempts and deleted within 24 hours.
Inferences — AI-generated Focus Plans and habit suggestions based on your health data and goals.
Sensitive Personal Information — health context you provide (exercise frequency, sleep habits, nutrition, stress levels, medical conditions, alcohol and tobacco use, family health history, medications), habit check-in data, voice check-in transcripts, and AI-generated health plans; and any health information you choose to include when you reply to a Kasane 3.0 beta email.

Sources of Personal Information

Directly from you (profile setup, health context entry, habit check-ins, voice check-ins).
Indirectly from you (limited App usage events via Apple's App Store Connect).
Directly from you when you join the Kasane 3.0 beta list on our website (email address and consent), and when you reply to a beta email.
Automatically when you submit the beta signup form (network information, processed by Cloudflare).

Use of Personal and Sensitive Personal Information

We use or disclose personal and sensitive personal information to:

Provide and personalize App functionality (display habits, track progress, generate Focus Plans).
Support, develop, and improve the App.
Respond to your support inquiries.
Send the Kasane 3.0 beta invitations and updates you asked for, and keep the signup form working by limiting repeated attempts.
Read replies to beta emails to learn what families need and to improve Kasane.
Comply with legal obligations or law-enforcement requests.

We do not use sensitive personal information for purposes outside those allowed by Cal. Civ. Code § 1798.121(a).

Sharing Personal Information

During the past 12 months we have disclosed the following categories of personal information to Anthropic, PBC (our AI service provider) strictly for processing AI requests. Requests are routed through our proxy server (a Cloudflare Worker) which does not log, store, or inspect content:

Personal information categories in Cal. Civ. Code § 1798.80(e).
Protected classification characteristics.
Inferences drawn from your data.
Sensitive Personal Information (health context needed for AI generation).

We enter contracts requiring Anthropic to keep this information confidential and use it only to perform the requested service. Anthropic does not train on data sent through their API and retains it for up to 7 days for safety monitoring before deletion.

We have also disclosed identifiers (your email address and consent record) and internet or network activity information to Cloudflare, Inc., which hosts our website, stores the Kasane 3.0 beta list and sends its emails on our behalf as a service provider, and the contents of replies to beta emails (which may include sensitive personal information) to Google LLC, which hosts our email inbox as a service provider.

We have not "sold" or "shared" personal information (including sensitive personal information) as those terms are defined under California Privacy Law, and we have no actual knowledge of selling or sharing personal information of consumers under 16.

Your Rights and Choices

California residents have the right to:

Know / Access & Data Portability — request details on personal information collected and receive a copy.
Delete — request deletion of personal information, subject to legal exceptions. The App provides deletion through profile and habit management. You may also uninstall the App to remove all local data. To remove a beta list signup, see section 10.
Correct — request correction of inaccurate personal information (most data can be edited directly in the App).
Opt-Out of Sale/Sharing — not applicable, as we do not sell or share personal information (including for cross-context behavioral advertising).
Right to Limit Use of Sensitive Personal Information — not applicable because we use Sensitive Personal Information solely for purposes permitted by California Privacy Law. You can restrict processing by not using AI-powered features or by deleting your data in the App.
Non-Discrimination — exercise of these rights will not result in discriminatory treatment.

How to Exercise Your Rights

Submit a verifiable request by emailing legal@kasanelife.com.

Only you (or a legally authorized representative) may submit a request. You may make two access/portability requests in a 12-month period. We will verify your identity before processing the request and will respond within 45 days (or up to 90 days with notice).

Retention

We retain personal information only as long as reasonably necessary to provide the App and its features or as required by law. Your data is stored on your device (and in your iCloud account) until you delete it. Kasane does not keep a server copy of your personal or health data. Transmissions to Anthropic are subject to their retention policy (up to 7 days for safety monitoring). Beta list signups are kept until you ask us to remove them and are deleted after one year without a renewed signup; the signup form’s rate-limit counters are deleted within 24 hours. Replies to beta emails are kept in our email until you ask us to delete them; asking to leave the beta list counts as asking.

Changes to This Notice

We may update this notice at any time. When we do, we will post the updated notice in the App and revise the "Last Updated" date. Continued use of the App after changes constitutes acceptance of the updated notice.
