Night Ledger (com.tea.sleepdiary) is a private sleep diary for iOS, published by World Seed, LLC. This Privacy Policy explains what information the Night Ledger app handles and how it is used.
In short: Night Ledger is designed for privacy. Your diary entries, settings, and data stay on your device. There are no accounts, no analytics, no advertising, no servers, no iCloud sync, and no tracking. World Seed, LLC never receives your data.
Information Stored On Your Device
Night Ledger stores all of your sleep diary entries, preferences, and reminder settings locally on your iPhone using on-device storage. This data is never transmitted to World Seed, LLC or any third party. It remains on your device until you delete the app or manually remove entries.
The app accesses local storage under Apple's required-reason API code CA92.1 (accessing information from the app itself). Our Apple Privacy Manifest declares zero collected data types and no tracking.
What We Collect
Nothing. World Seed, LLC operates no servers for Night Ledger. We do not collect, receive, store, or process any personal data from you. We have no access to your diary entries, sleep patterns, or any other information you record in the app.
Local Reminders
Night Ledger can schedule optional local reminders using iOS Notifications (UNUserNotificationCenter). These reminders are delivered entirely by your device and are not sent to or processed by World Seed, LLC. You control whether to enable notifications through the app and iOS Settings.
Exports
You can export your diary data to PDF, CSV, or JSON files. These exports are generated locally on your device. What you do with an exported file — such as saving it to Files, sharing it via email, or uploading it to a cloud service — is entirely your choice. World Seed, LLC never receives export data.
No Accounts, No Sync
Night Ledger does not require or support user accounts. There is no sign-up, no login, no iCloud sync, and no cloud backup managed by World Seed, LLC. Your data lives only on the device where you create it.
No Advertising or Analytics
Night Ledger contains no ads and embeds no third-party advertising or analytics SDKs. There are no trackers, no data brokers, and no profiling. We do not build advertising profiles or sell data to anyone.
No Network Access
Night Ledger does not connect to the internet, Game Center, leaderboards, or any remote service operated by World Seed, LLC. It works fully offline.
Children's Privacy
Night Ledger is a general-audience app and is not directed to children under 13. Because World Seed, LLC does not collect any data, we do not knowingly collect personal information from children. If you believe a child has provided us personal information, please contact us and we will address it.
Data Retention and Deletion
All data is stored locally on your device. You can delete individual entries within the app. Deleting the app removes all of your data from the device. Because World Seed, LLC never receives your data, there is nothing for us to retain or delete on our end.
Changes to This Policy
We may update this Privacy Policy from time to time. When we do, we will revise the "last updated" date shown at the top of this page. Your continued use of Night Ledger after an update means you accept the revised policy.
