SLEEP KEEPER · PRIVACY POLICY
Your night.
Your information.
Effective October 30, 2026 · App version 0.3.1

Your Sleep Journal
Sleep Keeper is a manual sleep journal. It stores the session start and end times, sleep and awake intervals, duration corrections and timing information needed to restore a running session. It also stores your theme, brightness, glow and tap-feedback settings. These records stay in this app's private storage on your device. They are used to show your own journal and run the app; VoidLight Creations does not receive them.
No Tracking Or Sensors
This version has no account, advertising, analytics, tracking SDK, network permission, microphone, camera, location or automatic sleep sensing. It does not connect to Health Connect or a wearable. Its only declared permission is vibration, used for optional tap feedback. The developer does not collect or share your journal, device identifiers or usage data through this app.
Backup And Restore
You can export completed sessions and corrections as a .skb file using Android's system file picker. A running session and settings are excluded. Files are not encrypted; their checksums detect corruption, not a trustworthy sender. Choose a private destination. A document provider you select, including a cloud provider, may receive and store the exported file under its own terms. Sleep Keeper does not upload it to the developer. Restore asks before adding sessions, skips matching records and preserves a running session. An internal safety copy is kept before a changing restore. Android automatic backup and automatic device transfer are disabled for app data.
Retention And Deletion
Records remain on your device until you clear Sleep Keeper's storage in Android Settings or uninstall it. Doing either removes the local journal, preferences and internal restore-safety copies. Keep an exported backup first if you want to retain completed sessions. Exported files and copies held by your chosen document provider remain until you delete them there. The app has no server account to delete and the developer cannot recover your local journal.
Google Play And Optional Contact
Google Play separately handles app distribution, the app purchase and any store diagnostics under Google's policies. This version has no in-app purchases or billing SDK. If you email support, your email address and anything you choose to send are processed through Outlook/Microsoft to answer your request. Do not send a sleep journal or other sensitive information unless it is needed and you choose to share it. Support correspondence is retained while needed to resolve the issue or meet legal obligations; you may request its deletion by email, subject to those obligations. It is not used for advertising.
Wellness, Not Medical Care
Logged sleep is your estimate. Sleep Keeper does not detect sleep, measure sleep stages or verify sleep quality. It is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. Consult a healthcare professional for medical advice, diagnosis, or treatment. The app is intended for adults and is not directed to children.
Changes
This policy describes version 0.3.1. New data handling or purchasing features will require an updated policy and applicable disclosures before release. The current public policy is available at the address above.
This website
This website presents Sleep Keeper and illustrative theme previews, not a sleep-recording service. It has no advertising, analytics scripts, contact form or tracking cookies in its source. Hosting and security providers may process ordinary request information, such as IP addresses and browser details, to deliver and protect the site. Visiting this page in a browser is separate from the Android app, which has no network permission.
