Privacy Policy

Effective 8 November 2026

In short: 1970s Calculator collects no personal data. There is no account, no analytics, no advertising, no tracking and no third-party code in the app. What you type into a calculator stays on your iPhone.

Who is responsible

This policy covers the 1970s Calculator app for iPhone and this website. They are made by Tibo Vincent-Ducimetière, an individual developer based in France, who is the data controller for the purposes of the EU General Data Protection Regulation (GDPR).

What the app collects

Nothing. The app does not collect, store on a server, share or sell any information about you. Specifically, it has:

• No sign-up or account of any kind.
• No analytics, crash reporting or usage statistics sent to the developer or anyone else.
• No advertising and no advertising identifiers.
• No tracking across apps or websites.
• No third-party SDKs or libraries that collect data.

What stays on your iPhone

Your settings and choices, such as which calculator you last used, colour themes, custom colours, tag names, key sounds and LED colours, are stored only on your device. Some of them are also kept in an App Group, a private storage area on your iPhone shared only with the app's own Control Center button, so that the button can open your last calculator. None of this leaves your device through the app. If you delete the app, this data is deleted with it.

Like any app, this data may be included in your own iCloud or computer backups of your iPhone, under your control and Apple's terms.

Purchases

Purchases are processed by Apple through the App Store. The developer never receives your name, email address or payment details. The app only checks Apple's anonymous purchase records on your device to know which calculators to unlock. For how Apple handles your information, see Apple's Privacy Policy.

Network use

The only time the app goes online is to contact the App Store, through Apple's own frameworks, to show prices, make a purchase or restore purchases. It contacts no other server. If you tap a web link in the app, such as the one in Credits, it opens in your browser.

Children

The app collects nothing from anyone, including children.

This website

This website sets no cookies, uses no analytics and loads nothing from third parties: no web fonts, scripts or trackers. The company hosting it may keep standard server logs (such as IP address, date and page requested) for security and operation, as all web hosts do; the developer does not use them to identify or track visitors.

Your rights

Because no personal data is collected, there is nothing for the developer to access, correct, export or delete. You still have all your rights under the GDPR and other applicable laws, including the right to complain to a supervisory authority; in France, that is the CNIL (cnil.fr).

Changes

If this policy changes, the new version will be posted on this page with a new effective date.
