Privacy Policy

E6B Slide Rule · Last updated 9 September 2026

E6B Slide Rule collects no data about you. None at all.

What the app stores

One number and one timestamp: the angle you last left the dial at, and when you left it there. This is kept on your device so the dial is where you put it when you come back to it, and it is discarded after 24 hours. It is not synced, not backed up to us, and never leaves the device.

What the app does not do

• It makes no network requests. The app has no reason to reach the internet and never does.
• It contains no analytics, no advertising and no third-party SDKs.
• It does not track you, on this app or anywhere else.
• It does not ask for your location, contacts, photos, health data, or any other permission.
• It does not use iCloud.

Children

The app is suitable for all ages and collects nothing from anyone, including children.

Changes

If this ever changes, this page will say so and the date above will be updated. Any version of the app that collects anything would also declare it in its App Store privacy label.
