No account to delete
ScientCalc · Expensive Petroleum · com.ep.paulscalc does not offer account registration and does not keep a server-side database of your calculation history. You can delete local data directly on your device.
Android
Open Android Settings → Apps → ScientCalc → Storage (or Storage & cache) → Clear storage / Clear data. Menu names vary by device. This removes locally saved history, settings, drafts, favourites and manual or cached rates, and cannot be undone within the app. Clearing only the cache may not remove saved app data.
Web and other devices
For the web calculator, open your browser’s site settings and delete the data for the calculator’s website. On iOS, delete the app and its data from device storage; offloading the app can preserve data. Repeat on each device or browser where you used the calculator. System backups may contain copies: manage or delete them through your operating-system or backup-provider settings.
