Frequently Asked Questions
Q. Where is my calculation history stored?
Your calculation data (history, memos, settings) is stored only on your device and is not uploaded to any server by the App. (Note that advertisements served by Google AdMob may transmit limited device/ad-interaction data; see the Privacy Policy for details.)
Q. Can I migrate my data to a new device?
The current version stores data locally only and does not offer automatic device-to-device migration. We recommend saving important results as memos and exporting them via the share feature if you need to keep them.
Q. I purchased Pro but I still see ads
If your purchase has not been applied immediately, please tap "Restore Purchases" on the Settings screen. If that does not resolve the issue, please contact us via the support email above.
Q. What does Pro include?
- 12 statistics functions in total: free tier includes 4 core (mean / SD / SEM / CV%); Pro unlocks 8 advanced (median / iqr / 95%CI / geomean / range / min / max / n)
- 24 conversion formulas (14 in free tier; Pro unlocks 10 more)
- Extended history retention (1 month / unlimited; free tier keeps 7 days)
- Up to 50 memos (free tier is limited to 5)
- Customizable keypad layout and conversion presets
- Ad-free experience
Q. Can I get a refund?
Refunds are handled by Apple under their refund policy and may be available depending on the circumstances. Please request a refund directly via Apple: https://reportaproblem.apple.com
Note that the developer cannot process refunds.
Q. How do I delete all of my data?
Uninstalling the App will delete all local data associated with the App.
Q. A calculation result looks unexpected
Please report it via the support email with the reproduction steps (input values, operation sequence, and displayed result). Including the App version and iOS version is helpful too.
