TradeCalc

Privacy Policy

Effective date: June 13, 2026 · TradeCalc: Construction Calc · App Harbour ApS

The short version: TradeCalc collects no data. None. The app is 100% offline, requires no account, contains no analytics, no ads and no tracking, and operates no server. Everything you enter stays on your device.

Data we collect

We do not collect, store, transmit or sell any personal data or usage data of any kind. The app:

Data stored on your device

Your calculations and settings are processed and stored only locally on your device. Every calculation happens on the device. We have no access to anything you enter, and deleting the app removes this data.

Purchases through Apple

The Lifetime purchase and the weekly and annual subscriptions are processed entirely by Apple through the App Store (StoreKit). We never see or store your payment details. Apple confirms your purchase status to the app on-device so the paid calculators can unlock. Apple's handling of your payment data is described in Apple's Privacy Policy.

Third parties

Apple, as the payment processor for in-app purchases, is the only third party involved in operating the app. We share no data with anyone, because we collect none.

Children's privacy

The app collects no data from anyone, including children.

Your rights

Privacy laws such as the GDPR give you rights over personal data a company holds about you. We hold none. If you contact us by email for support, we use your email address only to reply and you can ask us to delete the correspondence at any time.

Changes to this policy

If we ever change how the app works in a way that affects privacy, we will update this policy and the effective date above before the change ships.
