Privacy
Policy.
Calculator Ultra keeps your everyday math private. This policy explains what stays on your device and the one feature that connects to an external service.
Effective July 21, 2026
THE SHORT VERSION
No account. No ads. No sale of personal information.
Your app content stays on your device. Only live currency rates require a network request, and the number you type is never sent with that request.
Our privacy approach
Calculator Ultra is designed to work without an account. WokCode does not collect, sell, rent, or use your personal information for advertising, tracking, profiling, or third-party analytics. The app contains no advertising or third-party analytics SDKs.
Information stored on your device
Your calculations, calculation history, notes, memory values, saved conversions, date results, language, accessibility settings, selected theme, and widget state are stored locally in the app's private storage. WokCode does not receive this information. The app and its widget use an Apple App Group to share only the local state needed for the widget to work.
Currency exchange rates
On iPhone and iPad, the currency converter requests current exchange-rate data from Frankfurter at api.frankfurter.dev. The request includes the selected base-currency code, but it does not include the number you enter, your result, calculation history, notes, advertising identifier, contacts, photos, precise location, or account information. Like any internet request, the service operator and its infrastructure provider may process an IP address, request headers, and timestamps needed to deliver and protect the service. Returned exchange rates and their date are cached locally so recent rates remain available when the network is unavailable.
Offline features
Calculation, scientific functions, non-currency unit conversion, date tools, history, notes, the four built-in themes, language settings, and Home Screen widgets work without sending their content to WokCode. The current Android version does not request internet access.
Retention and deletion
WokCode does not operate a Calculator Ultra account or user-profile server. App-controlled information remains on your device until you delete individual history items, use an available in-app clear option, or delete the app. Device backups are controlled by your operating-system and cloud-backup settings.
Children's privacy
Calculator Ultra is a general-audience utility. It has no accounts, messaging, social networking, user-generated-content publishing, behavioral advertising, or features intended to collect personal information from children.
Disclosure and legal requests
WokCode does not sell personal information or share it for targeted advertising. We may disclose information only if required by applicable law or when reasonably necessary to protect users, WokCode, or the security of the service. Because WokCode does not receive your local app content, we generally do not have that content to disclose.
Changes and contact
If Calculator Ultra's data practices change, this page and the applicable app-store privacy disclosures will be updated before the new practices take effect. Questions about this policy can be sent to phakin.marketing@gmail.com.
