Your journal and exports
Sleep entries, notes, tags, and ISI responses are stored on your device. PDF and CSV exports are generated on your device; you choose where to save or share them.
Privacy Policy
Your sleep journal should stay quiet by default.
The core SleepLedger experience does not require an account and is local-first by default. Your diary and exports are handled on your device, and Apple manages purchases.
Purchases and restores
Apple StoreKit handles SleepLedger Pro purchases, restores, and transaction verification. The app checks verified StoreKit transactions to determine access to Pro features.
Apple Health
Where available, connecting Apple Health is optional and requires your permission. SleepLedger reads sleep timing and duration as background context. Deleting a SleepLedger record does not delete the original Apple Health samples.
App analytics and ad measurement
The next iOS update removes optional Meta and TikTok measurement, Apple Ads token exchange, and app conversion reporting. It does not record behavioral analytics events or request tracking permission. Earlier builds may still include optional ad measurement. Removing these integrations does not erase data previously sent by older versions.
Website and support
Cloudflare hosts this website. The website uses Cloudflare Web Analytics for cookie-free page-view and performance measurement. If you contact support, we receive the information you choose to include in your message.
Optional website behavior analytics
If you allow website analytics, Microsoft Clarity collects website interactions such as clicks, scrolling, page navigation, device/browser information, and session recordings to help us improve this website. Clarity may use cookies to connect visits. Advertising storage is denied. We do not send your in-app sleep journal, Health data, ISI answers, or exports to Clarity. This website's analytics is separate from the iOS app.
Clarity does not load before you allow it. Use Analytics settings in the footer to decline or withdraw consent; withdrawal reloads the page to stop recording. Your choice is saved in this browser for up to 180 days. Withdrawal stops future capture but does not erase previously collected sessions.
Retired hosted features
The website no longer provides device registration, sleep entry uploads, audio uploads, or server-generated exports. Retiring these interfaces does not itself erase data that may remain in older service storage. Contact support with questions about previously submitted data or deletion requests.
