Private diary
What's on your mind
stays with you.
Shiru is a diary for iOS and Android — encrypted on your device, no account, no server.
Coming soon — Shiru is currently in store review.
What makes Shiru different
Privacy-first
All entries stay on your device. AES-256 encryption via SQLCipher — we have no access to your diary.
No account needed
No e-mail, no login, no server sync. You authenticate with a PIN, password or biometrics — all on-device.
Mood & insights
Capture how you feel. A warm visualisation of your mood over time helps you notice patterns.
Photos, audio, location, weather
Enrich entries with images, voice notes, places and weather data. Everything optional — you decide.
Cloud backup with your password
If you want: end-to-end-encrypted backup to your own iCloud (iOS) or Google Drive (Android). Nobody else can read it.
Simple and warm
Minimal, editorial, free of distractions. Journalling as a calm ritual, not a to-do.
