Voice Calculator Privacy Policy
Updated: October 24, 2026
1. Calculation and voices
You can calculate and play the bundled voices without an account. The app does not request microphone, contacts, health or location access. Voice playback uses audio files included in the app; it does not record your voice.
2. Data stored on your device
Calculation history is stored in a local database. Preferences such as theme, voice, precision, text size and tour progress are stored on your device. Legacy local purchase, trial and identifier values may remain for compatibility; they do not restrict the current free features and are not sent by the current app. The developer does not receive your calculations, history or preferences.
3. App recommendations and network requests
At launch, on returning to the foreground or when opening a recommendation screen, the app may request public recommendation configuration from Alibaba Cloud OSS and app names, descriptions and icons from Apple services. Requests include public app identifiers and a store country code, using the App Store region when available or your device's region otherwise. They do not include your account identity, calculation history, purchases, receipts or a custom device identifier. Network providers receive connection information such as an IP address needed to serve these requests and process it under their own policies. The app does not use this information for analytics or profiling.
Recommendation configuration and app information are cached locally for offline display. These requests use a temporary network session without persistent cookies or credential storage. Unavailable recommendations do not prevent calculation.
4. Tracking and third parties
The current app does not integrate analytics or advertising tracking, build user profiles or report recommendation clicks. Tapping a recommendation, rating or sharing action may open an Apple service or a destination you choose. Those services handle subsequent activity under their own privacy policies. Copying a result places it on the system clipboard only when you choose to copy.
5. Retention and deletion
Local history and preferences remain on the device between launches. Clearing the calculator's displayed history does not delete the saved history database. Deleting the app, rather than offloading it, removes its local data. System backups may retain copies and may restore them when you restore a device; manage those copies in your Apple backup settings. The developer has no server copy of your calculation history or preferences to retrieve or delete.
6. Updates and contact
This policy is bundled with the app and can be read offline in Settings. Changes to the app's data handling will be reflected in an updated policy. For privacy questions, use the App Support information on this app's App Store page.
