Privacy Policy

Summary

We do not collect, sell or share personal data. The website and the app have no accounts, no analytics, no advertising and no tracking. Calculations run on your device.

The website

• The calculators run entirely in your browser. What you enter is not sent to us.
• The site sets no cookies and uses no analytics, advertising or social-media scripts. Fonts are served from our own domain.
• “Copy link to this sizing” puts your inputs in a link on your clipboard. It is shared only if you share it.
• The site is hosted by Vercel. Like any web host, Vercel processes technical request information, such as IP address, browser type and the page requested, to deliver pages and protect the service from abuse. We do not use that information to identify you. See Vercel’s privacy policy.
• If you email or call us, we use your message and contact details only to reply.

The iPhone app

Calculations and saved jobs

All calculations run on your device. Saved jobs, including job names and notes you enter, are stored only on your device and are not transmitted to us or to any third party. Deleting the app removes them.

PDF reports are created on your device. A report leaves your device only if you choose to share it, using the iOS share sheet, to a destination you select.

Purchases

Lifetime Pro is a one-time in-app purchase processed by Apple through the App Store. We do not receive your payment details. The app uses Apple’s StoreKit to confirm whether Lifetime Pro is active for your Apple Account.

Permissions

The app does not request access to your location, contacts, photos, camera, microphone or advertising identifier.

Children

Neither the website nor the app collects personal information from anyone, including children.

Changes

If these practices change, this page will be updated with a new effective date before the change takes effect.
