R-Type Systems LLC (“we,” “our,” or “us”) operates the Yufi application for macOS and iOS. Your privacy is paramount to us, and Yufi is built from the ground up to respect your personal data.

1. Information Collection and Use
Yufi does not collect, store, use, or share any personal information. * Your Documents and Data: All data, media, and files you add to a Yufi document are stored strictly locally on your device. We do not have servers that host your files. If you choose to save, sync, or backup your documents to external storage or cloud services (such as Apple iCloud, Google Drive, or Dropbox), that data is subject to the privacy policy of that specific third-party provider.

• No Tracking or Analytics: Yufi does not include any advertising software, tracking pixels, or third-party analytics frameworks. Your app usage remains completely private to you.

2. In-App Purchases and Subscriptions (Yufi+)
Yufi offers optional premium features via auto-renewable subscriptions processed securely through Apple’s App Store.

• We do not collect or store your financial information, credit card numbers, or billing addresses.
• All transaction details, payment processing, and subscription management are handled entirely and securely by Apple. Apple may provide us with anonymous, aggregated financial reports or anonymized transaction identifiers to validate subscription status, which cannot be linked back to you personally.

3. Changes to This Privacy Policy
We may update our Privacy Policy from time to time. Any changes will be reflected on this page with an updated “Last Updated” date.
