Privacy Policy

Practice stays on your device

Practice Combination Lock does not require an account and does not include advertising, analytics or tracking SDKs. The app does not send your combination or practice activity to a developer-operated server.

Your combination, color choice, sound and haptic settings, number-visibility preference, and local success count are stored on your device. The app does not request access to your contacts, photos, location, camera or microphone.

Purchases

Optional tips use Apple’s in-app purchase system. Apple processes payments. The app receives product and transaction information to complete purchases; the developer does not receive your payment-card information.

Sharing and support

When you print or share a combination guide, you choose where it goes using the system share sheet. Only share your combination with people you trust. If you email support, your email address and the information you include are received through the support mailbox and used to respond.

Children and families

The app’s practice features work without personal information. The optional Tip Jar is available in Settings. Please avoid including a child’s personal information in support messages.

Website and external services

These pages use no analytics, advertising scripts or cookies set by this website. The hosting provider may process normal request information, such as IP addresses, to deliver and secure the website. Apple and email services operate under their own privacy policies.

Storage and deletion

Local preferences and practice progress remain on your device until you change them or delete the app. To request deletion of information you sent by email, contact the support address below. Apple manages its own purchase records under its privacy policy.

Operator and contact

This app is operated by Chirag Mirani.
