Privacy policy

Last updated 3 November 2026

The short version: Margin doesn't collect any data. It has no accounts, analytics, tracking or advertising, and no servers of its own. Everything it knows about you stays on your iPhone.

What Margin stores on your iPhone

Margin saves your settings in storage shared between the app and its widgets, on your iPhone only:

Your theme, typeface and alignment.
Your lists of apps, and which list a Focus filter has made active.
The text of your note.
The place you chose for the weather: its name and coordinates.

Deleting the app deletes all of this. None of it is sent to us or to anyone else.

Permissions Margin asks for

All of these are optional. Margin works without them, with fewer widgets filled in.

Calendars — to show your next events in the Today and Next up widgets. Margin reads your events on your iPhone and never sends them anywhere.
Location — used once, while you're setting up the weather, to find where you are. Margin saves the place, not your location history, and doesn't track you after that.
Photos (add only) — to save a plain wallpaper in your theme's colour. Margin can't see the photos in your library.

Services Margin uses

Margin has no servers of its own. It uses two Apple services:

Apple Weather (WeatherKit) receives the coordinates of the place you chose, to return its forecast. See Apple Weather's data sources.
Apple Maps receives your location once, when you set up the weather, to turn it into a place name such as "London".

Apple handles this information under its privacy policy. The launcher opens other apps with their links. It doesn't send them anything.

Data we collect

None. Margin has no third-party code, analytics, crash reporting services or advertising. If you opt in to sharing crash reports or diagnostics with app developers in iOS Settings, Apple may share anonymised crash logs with us under Apple's privacy policy.

If you install a beta through TestFlight, Apple shares the information described in its TestFlight privacy notice, such as your name, email and any feedback or screenshots you choose to send.

This website

This website doesn't use cookies, analytics or third-party fonts or scripts.

Children

Margin isn't aimed at children and doesn't knowingly collect information from anyone.

Changes

If this policy changes, the new version will be posted here with a new date at the top.
