The useful details
Device & permissions
Android 8.0 or later. No login or network connection is required. Photo access is requested when you attach images.
Your data
Journal entries and photos stay in private app storage on your device. This version has no account, cloud sync, automatic upload, advertising or app analytics SDK. Export a JSON backup to preserve entries, photos and goals; CSV and PDF are also available for selected dates.
Read the full privacy policy (English)Good to know
- Cloud sync, encrypted exports, widgets and full parity with other journal apps are not included.
- This is a personal reflection tool, not mental-health diagnosis or treatment.
- Local backups and exports are unencrypted: protect the destination you choose. Restoring a backup replaces current local records after confirmation. Uninstalling or clearing app data removes private records; exported copies must be managed and deleted separately.
Daybook Privacy Policy
Last updated:
Publisher and scope
Daybook is published by Safeeas. This privacy policy describes the current local-first Android app and how your information is handled.
Information used on your device
Your dated reflections, mood choices, notes, activity labels and groups, goals, reminder settings, and photos you choose to attach. Calendar summaries and achievements are calculated from these local records. To display and edit your journal, show history and summaries, and deliver reminders you enable.
Network and providers
Daybook has no Internet permission. This version does not transmit your journal or app usage to Safeeas and includes no advertising or product-analytics SDK.
Permissions and optional features
Photos are selected through the Android document picker; Daybook does not request broad photo-library access. Optional notifications deliver local reflection reminders; boot/time-change events reschedule them. Optional app lock uses Android biometrics or the device screen credential. Daybook receives an authentication result, never a fingerprint, face template or your screen-lock credential. The lock hides screenshots while enabled but does not encrypt saved records or exports.
Export, backup and restore
Settings provides a JSON backup/restore and date-filtered CSV and PDF journal exports. Backups can include attached photos. These files are readable and are not encrypted by Daybook. Imported backups are checked against this app’s supported backup format and data rules. Replacing current local records requires confirmation. These local/manual exports are not an app-managed end-to-end encrypted backup service.
Delete your local data
You can remove reflections and attached photos using journal editing controls. To remove all app records, photos and settings, use Android Settings > Apps > Daybook > Storage > Clear storage, or uninstall Daybook.
Accounts and cloud
You do not need an account. This app has no account registration, sign-in, cloud backup or automatic synchronization. No app-managed record upload is enabled. Safeeas does not receive your local records through an account service.
Retention and deletion
Local records remain until you delete them, replace them by restoring a backup, clear app storage or uninstall the app. The app disables Android automatic app backup. Keep your own backup before destructive changes. Exported files, shared recipient copies and original files held by other apps are outside the app’s private storage; delete those separately. An uninstall cannot recall a file you have shared. Safeeas cannot recover unbacked-up local records.
Security and your choices
Android private app storage restricts ordinary access by other apps. App records are not protected by an additional app-wide encryption layer; device security still matters. Protect the device and any export destination. A system file picker can include third-party cloud-storage providers; choosing one transfers the exported file under that provider’s rules. The chosen provider controls that transfer and its stored copy; delete the copy separately with that provider. The app does not add advertising, advertising identifiers or behavioral-tracking SDKs. Android, Google Play and apps you explicitly choose may process information under their own policies.
Purpose and limitations
Daybook is a personal reflection and mood journal. It is not a medical device and does not diagnose, treat, cure or prevent any medical condition. Consult a qualified healthcare professional for medical advice, diagnosis or treatment. The app does not monitor entries for emergencies or provide crisis response.
Age and younger users
This app is intended for people aged 13 and older, including teenagers. It is not intended for children under 13. The app does not ask for a date of birth, verify age or provide parental controls. Where local law requires a parent or guardian’s consent, obtain that consent before using the app or sending personal information to support. A parent or guardian can help a younger user manage local records and remove them using the same deletion controls. An age of 13 does not by itself establish that a user is an adult under local law.
Information you send to support
Your local app records are not automatically sent to Safeeas. If you choose to email xiaozhu7888@gmail.com, we receive your email address, the message and any attachments you send. We use that correspondence to respond to your question, troubleshoot the issue or handle your privacy request. Email is handled through the email providers used by you and Safeeas under their own privacy practices. We retain support correspondence while the request is being handled and delete it after resolution unless a limited follow-up or legal record needs to be retained. You can ask us to delete support correspondence at the same address; any information that must be retained for a legal reason will be explained in our response. Do not send passwords or other secrets.
Contact and updates
For privacy questions, support or a request concerning support correspondence, email Safeeas at xiaozhu7888@gmail.com. Include the app name and a brief description of your request; avoid sending diary contents, health records, document scans or other sensitive attachments unless needed to resolve the issue. This policy was last updated on 24 October 2026. We will update it to explain material changes before enabling new data uploads or account features.

Version: 0.5.1 (6) / Android 8.0 or later / English app interface.
Install from this website
Download the APK from this page and open it. Android may ask you to allow this browser or file manager to install apps. Allow this installation source only if you trust it; you can turn that permission off after installation. If Android reports a security warning or blocks installation, stop and contact support.
Update without losing your records
Before updating, export a JSON backup from Settings and keep it safe. Use Android’s Update option with the same package (com.safeeas.daybook) and signing certificate. The older private test package is a separate app: installing this APK does not migrate its private records. Keep the old app and use its backup/restore controls; do not uninstall or clear storage to force an update. Contact support if installation is refused.
Your data stays on your device
No account is needed. Daybook has no Internet permission, cloud sync, automatic upload, advertising or app analytics. Reflections, moods and selected photos stay in private device storage. Optional biometric/device lock hides the app; it does not encrypt stored records or exports. JSON backups and CSV/PDF exports are readable. A cloud provider selected in the file picker may receive an export; protect and delete that copy separately.
Installation help: xiaozhu7888@gmail.com. Include Android version and the error; do not send journal entries, photos or backups.
