Your calculations stay on your device.

Information we collect

WCA Toolbox does not collect, transmit, sell, or share personal information. The app does not require an account and does not include analytics, advertising, tracking, or third-party data collection services.

Data stored on your device

When you save a calculation, WCA Toolbox stores the calculation input, result, name, and related timestamps locally on your device so that you can reopen, edit, duplicate, or delete it later. This information is not uploaded to a server or shared by the app.

Location information

If you choose to use the optional automatic magnetic-variation feature, WCA Toolbox may request access to your location while the app is in use. Location is used only on the device to estimate magnetic variation for headings. The app does not send location data to us or to a third party.

You can deny or revoke location access at any time in your device settings. The app remains usable without location access; you can enter magnetic variation manually when needed.

Support email

If you contact support by email, your email provider will process the information you include in your message. We use that information only to respond to your request. Please avoid sending sensitive personal or operational information by email.

Children's privacy

WCA Toolbox is not directed to children, and we do not knowingly collect personal information from children.
