Lockstitch (“Lockstitch”, “the app”) is a sewing puzzle game for iPhone, iPad and Android. It is published on Google Play by Imperial AI Limited and on the Apple App Store by Techarge Limited (each “we”, “us” for its store). This policy explains what the app does with your information.
Summary
- The app collects no personal data. There is no account, no analytics, no advertising SDK, no tracking and no crash reporting.
- The app makes no network requests of its own.
- Your game progress, wardrobe and settings are stored only on your device and are deleted when you uninstall the app.
- Purchases are handled entirely by Apple or Google. We receive no payment details.
Data we collect
None. We do not receive, collect, log, share or sell any personal or usage data. The app has no account or sign-in, does not talk to any server of ours, and contains no third-party analytics, advertising, tracking or crash-reporting SDKs.
Data stored on your device
The following is kept in the app’s local storage on your device and is never sent to us:
- your game progress and scores
- your wardrobe of garments you have made
- your settings, such as whether sound is on or off
- whether the purchased theme has been unlocked
Uninstalling the app deletes all of this data.
Purchases
Lockstitch has an optional one-time in-app purchase, the seasonal Halloween theme. Purchases are handled entirely by Apple (App Store) or Google (Google Play) under their own terms and privacy policies. We receive no payment details. The app only receives the store’s confirmation that a product was bought, so that it can unlock it. “Restore purchases” simply asks the store again.
Permissions
The app requests no device permissions beyond the platform billing permission used for the in-app purchase. It does not use your camera, microphone, location, contacts or photos.
Children
Lockstitch is suitable for all ages. It collects nothing from anyone, children included.
Your rights
Because we hold no personal data about you, there is nothing for us to access, correct or delete. All app data is on your device and under your control.
Changes to this policy
If this policy changes, the new version will be posted on this page with an updated “Last updated” date. If a future version adds optional accounts or online features, this policy will be updated before release.
