Privacy Policy
Effective October 7, 2026
The short version
D4D does not collect, store or share any of your data. Everything the app shows is read on your device and stays on your device. There are no accounts, no analytics, no advertising and no servers. The only exception is optional: Weather and Time to Leave ask Apple for the forecast and travel times, described below.
What D4D reads, and why
D4D only asks for a permission when you choose to turn on that feature, and you can change it at any time in Settings.
- Calendars – to show today's and tomorrow's events in the app and in your widgets.
- Reminders – to show your open reminders, and to add or complete a reminder when you ask it to.
- Apple Health – to show the values you choose: steps, active energy, exercise minutes, walking distance, flights climbed, heart rate and resting heart rate. D4D only reads these values. It never writes to Health.
- Location (while using the app or widgets) – only if you turn on the Weather or Time to Leave widget sections, to show the weather where you are and how long it takes to reach your next event that has a location. D4D never tracks your location in the background or keeps a history of it.
Where your data is kept
To display your widgets, D4D keeps a small copy of today's events, reminders, health totals, your settings and, if you use Weather or Time to Leave, your last known location, the latest weather and the next travel time, in a private storage area on your device that only the D4D app and its widgets can open. Deleting the app deletes this copy.
Health data
Health data is never used for advertising or marketing, never shared with anyone, and never stored in iCloud by D4D.
Third parties
D4D contains no third-party code, software development kits, trackers or analytics.
When you search for a city to add as a world clock, the text you type is sent to Apple Maps to find the city and its time zone, as with any Apple Maps search. It isn't linked to your calendars, reminders or health data, and nothing else is sent.
If you turn on Weather, your location is sent to Apple Weather (WeatherKit) to get the forecast. If you turn on Time to Leave, your location and the location of your next event are sent to Apple Maps to get the travel time. Apple handles this data under the Apple Privacy Policy. D4D sends nothing else, and nothing is sent to D4D or any other company. Weather data is provided by Apple Weather.
Children
D4D does not knowingly collect information from anyone, including children.
Changes
If this policy changes, the new version will be posted on this page with a new effective date.
