Effective October 17, 2026
Strong Sixteenth is a construction calculator app for Android, published by Mims Software Co LLC ("we"). This policy explains what the app does with your information. In short: nothing reaches us. Your work stays on your phone (and in your own Google backup, if you use it) unless you send it.
Nothing. The app has no account or sign-up, no ads, no analytics, and no crash reporting. It does not use the internet. We do not receive, store, or sell any information about you or how you use the app.
This data is stored in the app's private storage on your device. If you've turned on Android backup, Android also keeps a copy in your own Google account's backup, so your work comes back when you reinstall the app or move to a new phone. That copy belongs to you: we never receive it and can't see it.
When you tap Share, the app hands the text or PDF to the app you choose (for example, messages or email). What happens next is up to you and that app. The app never shares anything on its own.
The optional Pro unlock is sold through Google Play. Google processes the payment under Google's privacy policy. The app asks the Google Play app on your phone whether you own Pro. We receive the usual sales reports from Google Play (such as the country and amount of a purchase), and never your payment details.
The app is intended for adults and is not directed to children under 13.
If this policy changes, we'll update this page and its effective date.
