Privacy Policy — Dayhue

Effective October 20, 2026

The short version: Dayhue keeps your journal on your device. There is no account, no server and no analytics.

What Dayhue stores

Your moods, feeling words, tags, entries, written weekly recaps and (if you choose to keep them) voice recordings are stored on this device, in the app's protected storage. Dayhue has no servers and cannot see them. They leave the device only if you share or export them, or through your own device or iCloud backup (see Backups and deletion). Deleting an entry deletes it from the app. If you delete the app, this data is deleted with it.

What Dayhue does not do

• No account or sign-in.
• No analytics, advertising or tracking SDKs. No data is sold or shared.
• No third-party AI. Dayhue does not send anything you write or say to any AI service.

Permissions

Dayhue asks only when you use the feature, and every permission is optional:

• Microphone: when you tap Speak, so you can say an entry out loud.
• Speech recognition: only if Apple's newer on-device speech model is unavailable. Recognition still runs on this device.
• Face ID: when you turn on the lock in Settings, to unlock Dayhue.
• Notifications: when you set a daily reminder. It is a local notification scheduled on this device.
• Health (write only): when you turn on “Save moods to Apple Health” in Settings.

Voice entry

When you tap Speak, your speech is turned into text on this device using Apple's on-device speech recognition. Audio is not uploaded. By default the audio is thrown away after transcription; if you turn on "Keep the audio recording", it is saved only on this device. iOS may download Apple's speech model the first time you use voice entry.

Written recap and prompts (Pro)

The weekly recap and reflective prompts use Apple's on-device Foundation Models on devices that support Apple Intelligence. When you ask for a recap, the on-device model reads your moods, the feeling words you chose and your entry text to write it. The reflective prompts use only your tags. This happens on this device and nothing is sent anywhere. On other devices, a plain statistics recap is shown instead.

Apple Health

Saving to Apple Health is optional and off by default. If you turn it on, Dayhue writes the moods you log (and the feeling words you pick) to Apple Health as State of Mind. This is the only thing Dayhue does with Health: it writes, and never reads, shares or sends it. You can turn this off at any time; records already in Health stay there and you can manage or delete them in the Health app. Deleting an entry in Dayhue also removes its record from Health. Health data is not stored in iCloud by Dayhue.

Widgets, Siri and notifications

Widgets and Siri use a small file in a shared App Group container that holds each recent day's mood level and date. It never contains the text of your entries, so widgets show your mood level, never your words, even when Dayhue is locked.

Purchases

Purchases are handled by Apple through the App Store. Dayhue does not see your payment details.

Network use

Dayhue itself makes no network requests. The App Store handles purchases, and iOS may download on-device models.

Backups and deletion

Your device backup, and your iCloud backup if you use one, can include Dayhue's data, so a journal survives a restore to a new device. That backup is managed by Apple and your settings, not by Dayhue; Dayhue has no servers and no copy of your data. To delete your data, delete entries in Dayhue or delete the app. To remove it from backups, manage your backups in iOS Settings.

Export and your control

You can export everything as a zip (Markdown, JSON and CSV) from Settings at any time, free. You decide whether to share it.

Children

Dayhue is not directed to children.

Support and contact

Visit the support page, or email hello@nexg.tech

Not medical advice

Dayhue is a journal, not a medical device or therapy. Talk to a doctor or therapist for medical decisions. If you want to talk to someone, the Support screen lists crisis lines, and findahelpline.com lists helplines in 175+ countries.

Changes

If this policy changes, the new version will be published at the address above.
