J & S Studio Privacy Policies

At J & S Studio, we believe user privacy should not be a secondary thought. Our applications are built with an on-device-first design philosophy. We do not gather, store, track, or resell your personal information, records, files, or lists.

• 👉 ReSeller Receipts Privacy Policy - Automated iOS receipt scanner and cloud organizer for e-commerce resellers.

Global Privacy Practices

For all J & S Studio mobile applications:

• Local Database: All data you record (scanned books, vehicle VINs, receipt logs) is saved locally on your physical device using Apple SwiftData storage.
• No User Accounts: We do not require you to sign up for accounts, provide emails, or create passwords to use our utilities.
• Third-Party Libraries: We integrate standard SDKs like Google Mobile Ads (AdMob) for Standard (free) tier configurations to display banner ads. These SDKs may log system indicators or identifiers for standard ad attribution. If you upgrade to Premium inside the app, all advertisement components and trackers are completely disabled.
