Effective date: 15 August 2026.
The short version
Cable Size UK collects no data. There is nothing to opt out of, because nothing is gathered in the first place.
What the app does with your data
Every calculation happens on your device. The app has no user accounts, no analytics, no advertising, no tracking, and it makes no network connections. The circuit details you enter never leave your device, and the developer has no way to see them.
Purchases
The app is bought through Apple's App Store. Apple processes that transaction under its own privacy policy; the developer receives no personal information about you from it.
Changes
If a future version of the app changes any of the above, this policy will be updated before that version is released, and the change will be noted in the version's release notes.
