Privacy policy

Effective October 6, 2026. Knowear is published by Mason Isaacson. This policy explains how the app handles your information.

Your inventory stays on your device

Your welcome name, location names and notes, clothing details, and saved photos are stored locally. The app does not provide an account or cloud inventory sync. Device backups may include app data according to your Apple settings.

Optional AI photo identification

Knowear can be used to manage your inventory without sending photos to AI. Photo identification is optional. During setup, the app asks you once to confirm that you are at least 13 and, if you are under 18, that you have permission from a parent or guardian. You can leave identification off and enter details yourself.

When you identify a photo, a resized copy of that clothing photo is sent over HTTPS through our Cloudflare service to OpenAI. OpenAI screens and analyzes it to suggest item details. After identification, a separate resized copy is sent to OpenAI to remove the background while you review or save the item. The original stays on your device. Your welcome name, location names, notes, inventory, and your age or guardian-permission confirmation are not sent to OpenAI. You can turn identification off in Settings and enter details yourself.

Our Worker does not save a photo library or log image contents, prompts, or model responses. Cloudflare processes network information, including IP addresses, to deliver requests and limit abuse. OpenAI says API content is not used to train its models unless the customer opts in. The Responses API request disables response application-state storage, but OpenAI's standard abuse-monitoring logs may retain content for up to 30 days, unless longer retention is required by law or reasonably needed to protect OpenAI or others. OpenAI's safety systems may also retain an image for manual review if it is flagged as potential child sexual abuse material, even when retention controls apply. See OpenAI API data controls and Cloudflare's privacy policy. Avoid photographing sensitive documents or people when identifying clothes.

Subscriptions

Apple processes payments. RevenueCat validates purchases and manages subscription status using a generated anonymous customer identifier, purchase records, and technical information needed to provide the service. Purchase information also supports subscription reporting. When you request photo identification, our Cloudflare Worker uses that anonymous customer ID to check your membership and stores a hash for verification and usage limits; it does not save the ID as a user account. To enforce the annual AI allowance across restores, the service also stores a hash of the current App Store transaction, its access-expiration date, usage counts and temporary one-use processing tickets. Expired annual counters are retained for up to 90 days and removed on subsequent processing requests. We do not send your name, inventory, notes, or photos to RevenueCat, and we do not receive your payment card details. See RevenueCat's privacy policy.

App verification

Knowear uses Apple App Attest to protect photo identification from misuse. Our service retains an app-installation key identifier, its public key, a hash of your anonymous membership identifier, and a verification counter. Temporary challenges expire after five minutes. These records help verify requests and prevent replay; they do not contain your photos or inventory.

No advertising tracking

The app has no ads and does not use advertising identifiers or track you across other companies' apps and websites for advertising.

Your choices

Purchase and service records may be retained as needed to provide the service, prevent fraud, and meet legal obligations. For privacy questions or a data request, contact knowear.arrival679@slmails.com. If you contact us, we use the information you provide to answer your request.

Changes

We may update this policy as the app changes. The effective date above identifies the current version.
