🔒 Daylog — Privacy Policy

Effective date: 18 July 2026

The short version: your data never leaves your device unless you explicitly set up your own sync. We run no servers, collect nothing, and can't see your data even if we wanted to.

What data the app stores

Everything you enter — habits, moods, journals, time logs, workouts, tasks, notes, plans, events, articles — is stored locally on your device (browser localStorage). We do not operate any server that receives, stores, or processes your personal data.

What we collect

Nothing. The app contains no analytics, no ads, no trackers, no crash reporters, and no third-party SDKs that collect data.

Optional features that contact the internet

Google Sheet sync (optional, off by default): if you paste your own Google Apps Script link, the app sends your entries to your own Google Sheet in your own Google account. That data flow is between your device and your Google account — we are not involved. Governed by Google's privacy policy.
Health Connect readings are never included in this sync. Steps, distance, heart rate, sleep sessions, calories and workouts are stored in a separate place on your phone that the sync deliberately does not read, whether sync is on or off.
Background reminders via ntfy (optional, off by default): if you enable this, reminder titles/labels you write (e.g. "Log my day") are sent to the public push service ntfy.sh on a random secret topic so your phone can ring. Only reminder labels are sent — never your journal or tracked data.
Fonts: the app loads its typefaces from Google Fonts.

Device permissions and what they're used for

Daylog requests only permissions that power features you can see, and all data they produce stays on your device. Nothing is uploaded.

Usage access / screen time (PACKAGE_USAGE_STATS) — optional, off until you grant it: used solely for the app's digital-wellbeing feature: it reads how long your phone was in use today so Daylog can show your daily screen time and chart it against your mood. The figure is stored locally on your device only. It is never transmitted, never sold, never shared, and is not used for advertising or analytics. You can switch it off any time in Settings ▸ Auto-tracking ▸ Screen time, or revoke Usage access in Android settings.
Microphone (RECORD_AUDIO) — optional: used only while you actively tap the 🎤 Speak button, to dictate a journal entry or note. Speech recognition is handled by your device's own Android speech service; Daylog stores only the resulting text, locally. The microphone is never used in the background, and no audio is recorded, saved or transmitted by us.
Notifications, exact alarms, full-screen intent, vibrate, wake lock: used to deliver the reminders and alarms you create, and the ongoing notification while a timer is running.
Run at startup: used to restore your scheduled reminders after a phone restart.
Internet: used to load the app's own files and fonts, and only for the optional features listed below. No personal data is sent.

Health-related data

Any wellbeing figures you see (sleep hours, screen time, activity) are either typed by you or read from your device with your permission, and are stored locally on your device. Daylog is a personal journaling and productivity tool. It is not a medical device, provides no diagnosis or medical advice, and shares no health data with anyone.

Data deletion

Your data is yours: export a full backup anytime (Settings ▸ Backup & restore), and delete everything by clearing the app's site data / uninstalling. There is nothing to delete on our side, because we hold nothing.

Children

The app collects no data from anyone, including children.

Changes

If this policy changes, the new version will be posted at this URL with an updated effective date.
