Summary: Your calculations are never sent to us. In the free version they stay on your device; with SciCalc Pro, your history also syncs through your own private iCloud (Apple's CloudKit), staying in your personal iCloud account. The free version of SciCalc shows a banner ad from Google AdMob, which collects limited device and ad-interaction data to serve those ads. Upgrading to SciCalc Pro removes all ads. We have no account system and run no servers of our own.
SciCalc is developed by MW Supply Limited (“we”). This policy explains what stays on your device and what is processed by the limited third-party services we use to show ads (free version) and to offer an optional Pro upgrade. The app has no account system and no backend — you can use every feature without signing in to us.
SciCalc stores the following on your device so the app remembers it between launches:
This stays on your device, is never sent to us, can be cleared at any time with the Clear History button or the MC key, and is removed entirely if you delete the app.
iCloud sync (SciCalc Pro). If you subscribe to Pro, your calculation history is also synced through your own private iCloud database using Apple's CloudKit, so it stays in sync across your iPhone and iPad and is restored when you set up a new device. This data lives in your personal iCloud account under your Apple ID — it is visible only to you, handled under Apple's iCloud terms and privacy policy, and we never receive it or have access to it. History is not synced to iCloud in the free version.
The free version of SciCalc is supported by a single banner ad shown at the bottom of the calculator. It is served by Google AdMob (the Google Mobile Ads SDK). To serve it, Google may collect and process information including:
This information is collected and used by Google, not by us, under Google's Privacy Policy and as described in How Google uses information from sites or apps that use its services. MW Supply Limited only receives aggregate, non-identifying reports such as ad impressions and estimated revenue. Your calculations are never shared with Google or used to target ads.
App Tracking Transparency. iOS asks whether SciCalc may track you across other companies' apps and websites. If you choose “Ask App Not to Track,” the advertising identifier is not used and you will see only non-personalized ads. You can use the app fully either way.
Consent (EEA, UK & other regions). Where required by law, SciCalc uses Google's User Messaging Platform to ask for your consent before personalized ads are shown, and respects your choice.
Removing ads. Upgrading to SciCalc Pro removes the banner entirely. While you are a Pro member, the app does not request or display ads.
SciCalc Pro is an optional auto-renewable subscription (monthly or annual) that removes all ads, unlocks multi-function graphing (up to six functions at once), and keeps unlimited calculation history. Purchases, billing, renewals, and refunds are handled entirely by Apple through the App Store using StoreKit — we never see or store your name, card number, or Apple ID. To unlock Pro, the app checks your purchase entitlement directly with the App Store on your device; this check does not identify you to us. Manage or cancel anytime in iOS Settings → Apple Account → Subscriptions.
Apart from the advertising and purchase services described above — and, for Pro subscribers, syncing your history to your own private iCloud as described in section 2 — SciCalc makes no network requests of its own and has no servers to talk to. Your calculations are never transmitted to us, and in the free version they never leave your device.
To show ads in the free version, SciCalc includes two SDKs, both from Google:
Both are governed by Google's Privacy Policy. SciCalc contains no analytics frameworks and no crash reporting other than Apple's own first-party reporting (governed by Apple's privacy policy, and only if you opted in to Share With App Developers in iOS Settings → Privacy & Security → Analytics & Improvements). SciCalc Pro members are not shown ads, and the app does not request ads for them.
SciCalc does not access your location, camera, microphone, contacts, or health data. The advertising identifier is used only for ads in the free version, and only if you allow tracking as described in section 3.
SciCalc is a general-audience calculator rated 4+ on the App Store. Because the free version shows ads, we instruct Google to serve only family-appropriate (maximum content rating G) ads. We do not knowingly collect personal information from children. Upgrading to SciCalc Pro removes all ads.
If we change how SciCalc handles data, we will update this page and the "Last updated" date above. Material changes will also be reflected in the App Store privacy nutrition labels for the affected version.
