Voice AI Calculator — Terms of Service

Operated by Shanghai Gingko Intelligent Technology Co.,Ltd. (上海菁曜智科技有限公司). Contact: dianna@gingko-ai.com.

Using the calculator

The app accepts spoken or typed questions and provides a basic keypad. Speech recognition, AI interpretation and calculation results may be incorrect. Check the recognized question, assumptions, steps and result before relying on them. The app is not professional financial, medical or legal advice.

Free period and subscriptions

The free cloud-feature period runs for 14 consecutive days from first opening. Sign-in, account switching or deletion does not restart or extend it on the same installation. This free period does not create an Apple subscription or automatically charge you. Basic keypad calculation remains free after expiry.

Cloud voice, AI solving and review require an eligible trial or active plan. Monthly, quarterly and yearly plans provide the same features for different durations. The US prices are $1.99 per month, $4.99 per three months and $15.90 per year, subject to the price displayed by Apple at purchase and applicable taxes. The yearly plan is prepaid for one year, not monthly installments. A subscription starts only when you choose a plan and confirm purchase with Apple, and renews automatically unless canceled. Manage cancellation, renewal and refund requests through Apple. Restore Purchases is available in the app.

History and accounts

After sign-in and separately, explicitly enabling history backup, history synchronizes within your service region for access on other devices using the same account and region. Existing history remains accessible after trial or subscription expiry. Offline or failed uploads are not confirmed backups. Erasing local data before upload can lose pending records. China and international service accounts and data are separated; the app does not silently copy history between regions.

Deletion

You may initiate account deletion in the app, including for an automatically created guest account. Completed deletion removes local history and the account-associated active-service records described in the Privacy Policy. Deleted history cannot be recovered by registering again. A minimum original device trial state remains to prevent a fresh free period on that installation. Backup handling follows the verified Privacy Policy and deletion procedures; deletion does not mean every recovery copy is immediately physically erased. Deleting an app account does not cancel an Apple subscription.

Privacy and availability

History backup is separate from optional contribution of questions for calculation improvement. See the Privacy Policy for data fields, processing providers, service locations, retention and your choices. Internet access and provider availability are required for cloud services. Service functionality and these terms may be updated; relevant changes will be disclosed.
