Privacy Policy

Effective 7 September 2026 · Last updated 7 September 2026

This policy describes how the iPhone app HistoryCalc (bundle ID com.historycalc.historycalc) handles information. HistoryCalc is a calculator with an on-device history tape. It is not an account-based cloud service.

What stays on your iPhone

Calculation history, notes, favorites, language, and keypad preferences are stored only on your device. We do not sync this tape to our servers, and we do not operate a HistoryCalc cloud account for your calculations.

You can delete a single tape row, or clear all local history, in the app.

What we do not do

• No advertising SDK, no analytics SDK, no crash-reporting SDK in this version.
• No tracking across other companies’ apps or websites.
• No selling of personal data.
• We do not read your photo library in the background.

Sign in with Apple and purchases

You can calculate without an account. Sign in with Apple is used only when you buy or restore the one-time unlock.

If you sign in, Apple may provide a user identifier (and, on first authorization, an email). HistoryCalc stores the Apple user identifier in the iOS Keychain on this device so we can show signed-in state and offer account deletion. Purchase status is provided by Apple’s App Store / StoreKit. We never see your Apple ID password or payment card number.

Network access is used for Sign in with Apple, in-app purchase, and restore. Calculating, browsing the tape, discounts, and generating a share image work offline.

Photos

If you choose Save to Photos, the app writes an image you just created. That uses Apple’s add-only Photos permission. We do not upload photos.

Third parties

The only third party involved in these flows is Apple (Sign in with Apple, App Store, StoreKit, and the Photos app on your device). Their handling of data is governed by Apple’s policies.

Children

HistoryCalc is a general calculator tool (age rating 4+). It is not directed at children under 13, and it does not knowingly collect personal information from children.

Your choices

• Clear or delete tape rows in the app at any time.
• If you signed in, Settings → Account lets you remove the Apple sign-in on this device (and optionally delete local history).
• You can deny Photos permission; saving to the library will then be unavailable.
• Uninstalling the app removes local HistoryCalc data on that iPhone.

Changes

If this policy changes in a material way, we will update the date on this page. Continued use after an update means you accept the revised policy.
