Privacy Policy

We don't collect, store, or share any personal information. There are no accounts, no ads, no analytics, and no third-party tracking. Your calculations never leave your device.

None. 1+1 Calculator does not ask for your name, email, location, or any other personal information, and it contains no advertising or analytics software that would collect it in the background.

Everything you create in the app — your calculation tape, tabs, saved memory values, and settings — is stored locally on your device only. We have no servers that receive it and no way to see it.

The optional "Infinity" unlock is sold and processed entirely by Apple through the App Store. We never see or receive your payment details. To confirm whether you own Infinity, the app asks Apple's StoreKit for your purchase entitlement on your device; no personal information is sent to us in the process.

Apple's handling of your purchase is governed by Apple's Privacy Policy.

• No advertising or ad networks.
• No analytics, crash tracking, or usage measurement.
• No third-party SDKs that collect data.
• No selling or sharing of data — there is none to sell.

1+1 Calculator does not collect data from anyone, including children. It is safe for users of any age.

If the app ever changes in a way that affects this policy, we'll update this page and revise the "last updated" date above.
