WristCalc
Updated November 4, 2026
The app is provided by Shanghai Juzhen Zhiwai Keji Youxian Gongsi (transliteration of the Chinese legal entity name). BeyondMatrix is the app vendor name.
WristCalc is free, works offline and requires no account. The app has no ads, analytics SDK, developer backend or network permission. It does not transmit calculations to the developer.
Expressions and up to 20 successful results stay in the watch app's local storage for display, reuse and deletion. The app does not request location, contacts, health, camera or microphone access and does not collect data. Before first use, the Huawei edition displays the complete offline Chinese and English privacy policy. Agree and start saves your choice on this watch and opens the tools. Refuse and exit closes the app; reopening shows the policy again. Language and privacy choices also stay on this watch. The policy remains accessible from the home screen; uninstalling removes these local records. Other platforms retain their existing privacy entry.
The Apple edition also saves unfinished discount and offer-comparison drafts on this watch so you can continue later. You can discard those drafts from their respective screens.
Delete records in Recent. Uninstalling removes the app's active local storage; operating-system backups and restoration follow your device's settings and policies.
This help site uses GitHub Pages, with no site-added analytics, ads or login. GitHub may process ordinary web-request information under its privacy statement. Stores, operating systems and the GitHub support channel you choose to use have their own policies.
