Yizcho Island App Privacy Policy

Last updated: August 13, 2026

Yizcho operates the Yizcho Island iOS app. This page explains the app's privacy practices. The separate Yizcho Store Privacy Policy applies when you use the Yizcho website, store, physical-goods checkout, or other store services.

Cat camera, photos, and your Cat Archive

When you choose to create a Cat Card, the app uses Apple's on-device camera and animal-recognition technologies to check for a cat and create the card. Camera images, selected profile photos, Cat Cards, and the Cat Archive are stored locally on your device in this version of the app. We do not upload those photos to Yizcho, Supabase, Klaviyo, or Shopify. The app does not request your precise location, microphone, contacts, or advertising identifier for this feature.

Optional Yizcho account

You can use the main Cat Card and Archive features without creating an account. If you choose to create an account, we process your email address, a Yizcho/Supabase user identifier, account timestamps, language or device-region setting, and your marketing choice. Your password is sent directly to Supabase Auth over an encrypted connection for authentication; the Yizcho app does not store your password in readable form.

We use Supabase to provide authentication, account security, and order-linking features. We use Klaviyo for account-related communications and, only when you actively turn on the optional marketing switch, Yizcho news and availability updates. Creating an account does not subscribe you to marketing by default. You can unsubscribe from marketing messages at any time.

Physical products and Shopify checkout

The app may show physical art dolls or other physical products. Product availability, cart creation, checkout, payment, fulfillment, and shipping are provided by Shopify and its payment partners. Checkout opens in a system-provided Safari view. Shopify may collect information you enter there, such as your name, email, phone number, billing and shipping addresses, and order details, under this Privacy Policy and Shopify's applicable notices. Yizcho does not receive or store your complete payment card number. The app and our order service may retain a cart or checkout-session identifier, product and variant identifiers, purchase amount and currency, order status, and tracking information so that you can view order progress and we can fulfill and support the order.

Public World view and analytics

The app's public World view uses a non-persistent web view and blocks the marketing and advertising trackers configured for the general Yizcho website. The normal website, and the Shopify checkout opened in the system Safari view, may use cookies or similar technologies as described elsewhere in this Privacy Policy. The iOS app does not use the advertising identifier and does not combine app data with third-party data for targeted advertising or advertising measurement.

Technical operations and service providers

Our infrastructure providers may process limited technical request information, such as network address, request time, route, response status, and security or diagnostic information, to authenticate requests, prevent abuse, maintain reliability, and troubleshoot the service. We disclose data only to service providers needed to operate the app and store, or when required by law; we do not sell personal information.

Why we process information

Where applicable law requires a legal basis, we process information to provide features you request and perform our contract with you; with your consent for optional marketing; for legitimate interests such as security, fraud prevention, support, and service reliability; and to comply with legal obligations. You may withdraw marketing consent at any time without affecting processing that occurred before withdrawal.

Retention and deletion

You can delete an optional Yizcho account inside the app under My > Account & Security > Delete cloud account. A successful deletion removes the Supabase authentication identity and app profile, signs out active account sessions, clears the account profile photo stored by the app, and requests deletion of the associated Klaviyo profile. If that deletion request cannot be completed, the app reports an error so you can retry or contact support.

Deleting a cloud account does not silently erase the separate Cat Archive stored only on your iPhone. You can remove individual Cat Cards or erase the full local Cat Archive from the My tab in the app. Deleting the app also removes its remaining local data. Order and transaction records may be retained or de-identified where reasonably necessary for fulfillment, fraud prevention, accounting, tax, legal, or dispute-resolution obligations.

Your choices and contact

You may decline camera access, use the app without an account, leave marketing turned off, unsubscribe from marketing, delete your cloud account in the app, and contact us to request access, correction, or deletion where applicable. For privacy or account-deletion help, email hello@yizcho.com or use our Yizcho Island App Support page.

Children

Yizcho Island is not directed to children under 13, and we do not knowingly collect personal information from children under 13. A parent or guardian who believes a child provided personal information may contact us to request deletion.

Changes

If app features or data practices change, we will update this section and the App Store privacy disclosures before or with the relevant release, as appropriate.
