1. The short version
I don't collect any of your data.
Sunrise, sunset, twilight and day length are all worked out on your iPhone. Lighter Days doesn't need the internet for any of that.
If you share your location, it's sent to Apple Maps for the name of the town and its time zone. A city you search for goes to Apple Maps too. Apple handles those requests under its own privacy policy.
Nothing is sent to me or kept on a server, and nothing is sold or shared. There are no accounts, ads, analytics or tracking.
The place you pick and your settings stay on your iPhone. Deleting the app removes them.
The sections below go into more detail.
2. Your location
Sharing your location is optional. Lighter Days asks for it only while you're using the app, and only to set the sunrise and sunset times for where you are. It never asks for your location in the background, and the widgets don't use it at all; they work from the place you last saw in the app.
When you share your location, your coordinates are sent to Apple Maps to look up the name of the town and its time zone. They aren't used for anything else.
Without your location, Lighter Days uses the city for your iPhone's time zone, or a city you search for.
3. City search
What you type into the city search is sent to Apple Maps to find matching places. The city you pick is looked up with Apple Maps for its time zone.
4. Clock-change reminders
If you turn on reminders, Lighter Days asks for permission to send notifications and schedules a local notification on your iPhone for the evening before the clocks change. The reminders are set up on your iPhone; nothing is sent to a server to schedule them.
5. What stays on your iPhone
The following is stored only on your iPhone, in storage that belongs to Lighter Days and its widgets:
- The place you picked or the last place your location gave: its name, coordinates and time zone.
- Your settings, including whether reminders are on.
None of it is uploaded, synced or shared. Deleting the app removes it. Device backups may keep app data according to your settings.
6. Third-party services
The only outside service is Apple Maps, as described above. It handles those requests under Apple's Privacy Policy.
Lighter Days has no analytics, ads, tracking or third-party SDKs, and no account to create. I don't run a server for it. It's a one-time purchase, and Apple handles the payment.
