Riseline: Stair Calculator · last updated 2026-10-30
Riseline: Stair Calculator works fully on your device. We do not collect, store or share any personal data, and the app has no account, no analytics and no advertising.
Everything you enter stays in the app's storage on your device. It is never sent to us or to third parties. If you create a backup or an export, you choose where the file goes.
The app checks our server at appfactory.pro for updates to its guide library. These requests contain no personal data, and we keep no logs of them.
Optional purchases are processed by Apple (App Store) or Google (Google Play) under their privacy policies. We receive no payment details.
The app asks for each of these only when you use the feature that needs it, and you can change it in your device settings at any time:
We hold no data about you, so there is nothing for us to keep or delete. Your records stay on your device until you delete them in the app or delete the app, which removes all of its data. Backups and exports you saved yourself stay where you put them until you delete them.
If you write to us, we receive your email address and what you send. We use them only to answer you, do not share them with anyone else, and delete the correspondence when you ask.
The app is not directed to children under 13 and does not knowingly collect any data from them.
If this policy changes, the date at the top changes with it.
