Privacy Policy
Last updated July 29, 2026
The short version
Dayword does not collect, transmit, or sell your personal information. The app has no accounts, no analytics, no advertising, and no third-party trackers. Everything the app knows about you stays on your device.
Information we collect
None. We do not operate a server that receives data from the app, and the app does not ask you for a name, email address, phone number, or any other identifier.
Information stored on your device
To do its job, Dayword saves the following locally on your iPhone, in the app's own storage and its shared app group container (used so the widget can display your words):
- Your learning progress — which words you've seen, how you rated them, and when each is next due for review.
- Your vocabulary calibration result, if you take the optional estimate.
- Your preferences — daily new-word limit, simplified or traditional characters, and reminder time.
This data is never sent to us. It is included in your iPhone's backups if you have iCloud Backup or encrypted local backups enabled, in which case it is handled under Apple's privacy policy, not ours. Deleting the app, or using "Delete all learning data" in Settings, deletes this data.
Notifications
If you turn on the daily reminder, Dayword schedules a local notification on your device at the time you choose. Local notifications never leave your iPhone and do not involve a push server. You can turn reminders off at any time in the app's Settings or in iOS Settings.
Network access
The app's vocabulary, example sentences, and audio ship inside the app itself. Dayword makes no network requests to us or to any third party in normal use.
Children
Dayword is suitable for general audiences and does not knowingly collect personal information from anyone, including children under 13.
Your rights
Because we hold no data about you, there is nothing for us to export, correct, or delete on your behalf. You control all of it directly on your device. If you have a question about this, write to us at the address below and we'll answer.
Changes to this policy
If a future version of Dayword adds a feature that involves sending data off your device — for example, optional sync across devices — we will update this page before that version ships and describe exactly what is sent and why. The "last updated" date at the top will change when we do.
