Voice AI Calculator is operated by Shanghai Gingko Intelligent Technology Co.,Ltd. (上海菁曜智科技有限公司). Contact: dianna@gingko-ai.com. This policy describes the company app and its connected services.
Basic keypad calculations and supported expressions run on your device. When you sign in and explicitly enable history synchronization after reading its disclosure, calculation records are synchronized to your account in the selected service region so that you can access them on another device signed in to the same account and region. Records include your question, expression, result, available calculation steps, timestamps, the language of the saved record, input-source category, and units, follow-up context or verification status necessary to restore the calculation record. History backup excludes token usage, cost estimates, trace identifiers, speech-recognition model details or recording duration, confidence scores and latency measurements. This includes calculations completed locally, not only questions sent to AI. History synchronization is off until you explicitly enable it. Merging existing guest records is a separate disclosed choice. History synchronization does not include voice recordings and is separate from optional question contribution for product improvement. Statements about temporary AI-processing retention apply only to solving requests; your voluntary history backup stores the question text and calculation record for later access.
When the network is unavailable, records wait on your device for retry. A record is not backed up until upload is confirmed; pending or failed records may be lost if local app data is erased before synchronization. Existing local records may be merged after the sign-in notice; records already discarded by earlier app versions cannot be recovered. Access to existing account history does not end when the free period or subscription expires. Avoid entering sensitive personal information in calculation questions.
With your cloud-processing consent, audio is transmitted to Alibaba Cloud for speech recognition, and calculation questions and relevant calculation context are transmitted to Alibaba Cloud Model Studio for AI solving or review. This includes the content needed to answer a follow-up question. Voice feedback also uses cloud speech recognition. Our application database does not store recordings. This does not mean that our processing providers retain no request data: provider storage, security processing and legally required retention follow their service terms and privacy notices. Alibaba Cloud states that customer data is not used for model training. We have not verified or promised Zero Data Retention for this app.
The app uses separate China and US service backends, with service selection based on network country and the signed-in service region. Our international service uses Alibaba Cloud model and speech endpoints in the Singapore region; the China service uses Beijing-region endpoints. These are the running service endpoints verified on November 4, 2026, and do not guarantee that all provider processing or retention occurs at that gateway location. A US App Store listing does not mean that all processing takes place in the United States. Provider processing is governed by the applicable regional service terms and privacy notices.
Sign in with Apple supplies an account identifier used to authenticate you. Our database stores account identifiers, regional account records, sessions, trial periods and verified subscription information such as product, transaction identifiers and validity periods. Apple handles payment-card information; the app does not obtain your card details. A minimal original trial deadline and a server-signed trial proof are retained in secure storage on this device after deletion to prevent account deletion or switching accounts from restarting the 14-day period. They do not contain your calculation history or previous account identity. We do not promise to identify the same person after complete device erasure or on a new device.
Our service records daily allowances, temporary concurrency permits and available model-usage counts to provide cloud access, enforce limits and maintain security. These usage counters do not include question text, audio or authorization tokens. Service and network infrastructure may also process connection metadata such as IP addresses and request timestamps. These records are not used for advertising tracking.
If you separately enable question contribution in Privacy Settings, new redacted questions, expressions, results and fixed outcome categories may be submitted to improve calculation reliability. This is off by default. Old history is not uploaded retroactively. Redaction can miss personal information; submitted content is not guaranteed anonymous. Records are internally linked to your account for deletion, and authorized administrators can review them. Disabling contribution stops future submissions but does not itself delete existing submissions. If you submit Feedback, the feedback text, input method, app version, language and submission time are stored with an account association for support and troubleshooting.
Account-associated records, feedback and contributed questions remain in the active database until the account is deleted; the current implementation does not apply an automatic age-based expiry to those submitted-content records. Account deletion removes the current regional account and its associated active-database history, linked guest records, feedback and contributed questions, and clears local account data and calculation history. Completed deletion cannot be undone, including by registering again with the same Apple account. Only the minimum device trial state described above remains; account-linked trial eligibility records are deleted. Daily usage counters are limited to at most 32 UTC dates and cleanup runs on a later service admission; expired temporary usage permits are cleaned up on a later admission after two days. Copies in backups are not erased immediately by account deletion. The current US automated database and log backup settings retain backups for 7 days. Separately created manual recovery snapshots do not have a verified automatic 7-day expiry, so we do not promise that every backup copy disappears within 7 days. Backup copies are separate from active-account records; contact us for a deletion request involving retained recovery copies. We restrict restoration of recovery copies so that an older backup cannot simply return deleted account data to active service. If the latest deletion state cannot be verified, restoration to public service is blocked until it can be verified. Backup copies are not offered as a way to recover a deleted account. This does not mean that all recovery copies are physically erased immediately. Provider retention is separate from our own database and may include legal or security exceptions.
You may use the free basic keypad without agreeing to cloud processing. You can withdraw cloud-processing consent and turn off optional contribution through Privacy Settings, and clear history through the history controls. When history is bound to your account, clearing history also clears that account’s cloud history in its service region. A clearing request made offline waits for synchronization when the connection returns; cloud clearing is not complete until the service confirms it. To delete your current regional account, open Account & Membership, then Account settings, then Delete account. Signed-in users confirm their identity with Apple; a separate deletion entry is provided for guest accounts. Read the irreversible-deletion warning before confirming. Deletion does not cancel an Apple subscription; manage or cancel it through your Apple Account. China and US accounts are separate. For privacy or deletion questions, contact dianna@gingko-ai.com.
We use Apple for sign-in and in-app purchases and Alibaba Cloud for hosting, speech recognition and AI processing. Information may also be disclosed when legally required. We do not use the app for third-party advertising or tracking users across other companies’ apps and websites. We do not promise that content submitted to cloud services is anonymous.
The app is a general-purpose calculator and is not offered as a Kids Category service. We use HTTPS/WSS, account controls and restricted administrative access to protect service data; no system can guarantee absolute security. We may update this policy when practices change. Material changes to data handling will be disclosed in the app or the updated policy. This policy applies from November 5, 2026 once the corresponding service release is available.
