Tap Drill Chart & CNC Speeds — Privacy Policy

1. No data is collected

The app does not collect, store on a server, or transmit any personal information. There is no account to create, no sign-in, no email address requested, and no analytics or advertising software of any kind inside it.

The tool diameters, materials, thread sizes, and machine limits you type are saved on your iPhone only, so the app can show the same values when you reopen it. Deleting the app deletes them.

2. No tracking, no advertising

There is no advertising in this app and no tracking of any kind. Because nothing is tracked, the app never shows the "Allow this app to track your activity" prompt — that prompt exists to ask permission for something this app does not do.

3. Works with no internet connection

Every calculation, table, and reference document runs entirely on your device. The app makes no network requests during normal use. You can keep it in airplane mode permanently and lose nothing.

4. If you email us

The app has buttons that open your mail app to report a problem, suggest a feature, or report a wrong number. Those buttons pre-fill the app version and your device model so we can answer without asking you questions back. Nothing is sent unless you press send yourself, and we use those messages only to reply to you and fix the issue.

5. Purchases

The app is a one-time purchase through the App Store. Apple handles the transaction; we never see your payment details. There is no subscription and no in-app purchase.

6. Children

The app is a professional tool for machinists and is not directed at children. Since it collects no data at all, it collects no data from children either.

7. Changes to this policy

If a future version of the app ever collects anything, this page will be updated before that version is released, and the App Store privacy label will be updated to match.
