Privacy Policy

Who is responsible

RowLilt is provided by WeiYue Zhang (“we,” “us”). This policy covers the RowLilt iPhone app and this website. Contact us at qpalzmxncbcbxnzm@gmail.com with privacy questions or requests.

Your projects and imported files

Project names, imported PDF patterns and images, part details, counters, reading positions, notes, and undo history are stored locally in the app on your iPhone. We do not upload this project content to our servers or to RevenueCat. RowLilt has no user accounts and no automatic project cloud sync.

When you export or share a backup, you choose where the file goes. That file contains project content, including its pattern and progress. The destination app, person, or storage provider handles the copy under its own practices. Device backups or storage services you enable are also controlled by you and those providers.

Purchases and Pro access

Apple processes the in-app payment. RevenueCat helps check purchases, restore access, and manage the Pro entitlement. It processes an automatically generated anonymous app user ID, purchase records and receipt or transaction information, and technical information needed for the service, such as app and operating-system versions, device type, locale, and currency.

We use purchase information for app functionality, fraud prevention, and purchase statistics. RowLilt does not send your name, email address, project files, or notes to RevenueCat. We do not receive your full payment card details from Apple.

For more information, see RevenueCat’s privacy information and Apple’s privacy information. Restoring a purchase restores Pro access; it does not transfer local project files.

No advertising or advertising tracking

RowLilt does not display ads, use an advertising identifier, sell your personal information, or use your data to track you across other companies’ apps and websites for advertising. The app does not include a separate advertising or behavioral analytics SDK.

When you contact support

If you email us, we receive your email address and the message, screenshots, or other information you choose to send. We use this information to respond, investigate the issue, and maintain support records. Email is handled by our email provider.

If you choose to provide a purchase support ID, we may use it to locate the purchase record relevant to your request. Please avoid sending passwords, payment card details, or pattern files unless they are needed and you have the right to share them.

When you visit this website

This site is hosted by Cloudflare. To deliver and protect the site, Cloudflare may process connection and request information, including IP addresses, request details, and browser or system information. See Cloudflare’s privacy policy.

We do not embed advertising, analytics scripts, external fonts, or social trackers on this website. The site does not set advertising or analytics cookies. The hosting provider may use technical security cookies where needed to operate its services.

Retention, deletion, and your choices

You control local project files. Delete a project in the app to remove its local copy. Removing the app may remove its local data. Copies you exported, shared, or included in device backups must be managed separately at those destinations.

Purchase records are retained as needed to provide and restore access, resolve purchase issues, prevent fraud, and meet legal obligations. Support messages are kept as needed to handle the request and related follow-up. Removing the app does not automatically erase records held by Apple, RevenueCat, or an email provider.

Depending on where you live, you may have rights to access, correct, delete, or obtain a copy of personal information, or to object to or restrict certain processing. Email us to make a request. We may need enough information to verify and locate the relevant record. We cannot retrieve local project files from your device. You may also contact your local data protection authority.

Service providers and processing locations

We use service providers only for the purposes described here: purchase management, payment processing, email support, and website delivery. Providers may process information in countries outside your own. We may also disclose information when legally required or as necessary to protect the app and its users.

Policy updates

We may update this policy when the app or our practices change. The date above identifies the latest version. Material changes will be described here or in the app, as appropriate.
