Privacy Policy for Double Trouble

Last updated: 6 July 2026

Double Trouble is a darts checkout trainer for iPhone. This policy explains, as simply as possible, what happens to your data when you use it.

Short version

Double Trouble collects nothing. There is no account, no backend server, and no analytics or advertising SDK of any kind. Every piece of data the app creates — your name, your practice history, your settings — stays on your device, in the app's local storage, for as long as the app is installed.

What the app stores locally

• The name you enter on first launch (used only to personalize on-screen text)
• Your practice sessions and attempts (targets, darts thrown, accuracy)
• Your preferences (sound, haptics, default timer length, preferred double order)

None of this ever leaves your device. It is not transmitted to us or to any third party, because the app has no network access to send it anywhere.

Data collection, tracking, and third parties

We do not collect, sell, or share any personal data. We do not use cookies, third-party analytics, advertising networks, or any form of cross-app or cross-site tracking.

Deleting your data

Deleting the app from your device permanently deletes all of its local data. There is nothing stored anywhere else to delete.

Children's privacy

Because the app collects no data from anyone, it does not knowingly collect data from children either.

Changes to this policy

If this policy ever changes — for example, if a future version adds a feature that involves data leaving the device — this page will be updated and the "last updated" date above will change accordingly.
