Effective Date: November 7, 2026
Calcwick is a calculator and converter for iPhone and iPad published by EqualInformation, LLC. You type a phrase such as "18% tip on 64.50 split 3" or "2 cups in ml" and it answers. This page explains what stays on your device and what the advertising and purchase services do.
There is no sign-up and no cloud copy of what you type. We do not ask for your name, email address or phone number and we run no server that receives your calculations.
Everything you type (the tape, History, variables, favourites, custom units) is stored in the app's own storage on your device. The reading of your phrases happens on the device. A small list of your favourite conversions and their answers is also placed in a shared keychain item so the Home Screen widget on the same device can show them; it never leaves the device.
Rates come bundled with the app and can be refreshed on request from the European Central Bank euro foreign exchange reference rates (www.ecb.europa.eu), which are free to obtain from the ECB website. Refreshing requests one public file; nothing about you or your calculations is sent. Cross rates between two currencies are calculated by Calcwick. Rates are for information only and are not endorsed by the ECB.
The free version shows ads supplied by Google AdMob: banners on some screens, an occasional full-screen ad at a natural pause, and optional videos you can watch to earn ad-free time. Before any ad is requested the app asks the App Tracking Transparency question and then, where it applies, Google's consent form. If you decline, ads are not personalised. AdMob may collect device identifiers and ad interaction data as described in Google's privacy policy. Calcwick shows no ads before your first answer and none while you type.
You can remove ads with an auto-renewing monthly subscription or earn ad-free time by watching short videos. Purchases are handled by Apple through the App Store; we never see your payment details and the app only learns whether a subscription is active.
Calcwick is not directed at children under 13 and does not knowingly collect data from them.
None of your content. The app contains no analytics or crash-reporting library of its own. Apple may provide us with aggregated, non-identifying App Store statistics.
If this policy changes, the date at the top changes and the new text replaces this page.
