What Data LifeLog Stores
All data you create in LifeLog — including notes, note content, photos, categories, tags, and reminders — is stored only on your device in a private, encrypted database. This data:
- Is never uploaded to any server
- Is never shared with any third party
- Is never used for advertising or analytics
- Is never accessible to other apps on your device
- Is deleted permanently when you uninstall LifeLog
Crash Reporting (Firebase Crashlytics)
LifeLog uses Firebase Crashlytics, a service provided by Google, to automatically collect crash reports when the app encounters an unexpected error. This helps us identify and fix bugs.
When a crash occurs, Crashlytics may collect:
- The crash stack trace (technical description of what went wrong)
- Your device model and Android OS version
- The LifeLog app version
- The timestamp of the crash
- Two app-state values we attach: the database schema version number and whether app-lock is enabled (true/false — not the lock credential itself)
Crashlytics does not collect your notes, photos, categories, tags, or any content you have written in the app. Crash reports contain only technical diagnostic information.
Firebase Crashlytics is governed by Google’s Privacy Policy. You can learn more about how Firebase handles data at firebase.google.com/support/privacy.
App-Lock Credentials
If you enable the PIN, pattern, or biometric app-lock feature:
- PIN and pattern credentials are hashed using PBKDF2 with a unique random salt and stored in encrypted storage backed by the Android Keystore. The original PIN or pattern cannot be recovered from the stored value.
- Biometric authentication is handled entirely by Android’s built-in biometric system. LifeLog never accesses or stores your fingerprint or face data.
- Lock credentials never leave your device.
Export and Import
When you use the Export feature, LifeLog writes a file (JSON or CSV) to a location you choose on your device. That file is entirely under your control. LifeLog does not transmit exported files anywhere. If you share an export file with another person or service, you are responsible for the privacy of that file.
Photos
Photos you attach to notes are stored in LifeLog’s private app storage on your device. They are not uploaded or shared. If you use the “Save to device” option in the photo viewer, a copy is placed in your device’s photo gallery — that copy is then subject to your device’s own photo storage and backup settings (e.g. Google Photos auto-backup).
Local Notifications (Reminders)
Reminders are scheduled and delivered entirely on your device using Android’s notification system. Reminder content is not sent to any server.
Device Backups
LifeLog is configured to exclude its database, settings, and photos from Android’s cloud backup system (Google One Backup) and device-to-device transfers. This prevents your private journal data from being stored in Google’s cloud without your explicit knowledge. If you want to back up your data, use LifeLog’s built-in Export feature.
Children’s Privacy
LifeLog does not knowingly collect any information from children under the age of 13. The app does not collect personal information from any user.
Changes to This Policy
If we make material changes to this policy — for example, if we add a new feature that involves data collection — we will update the Effective Date above and note the change in the app’s release notes.
