Updated 21 October 2026. This policy covers the RiseSpan: Slope Calculator app for iPhone and iPad only.
RiseSpan does not collect, transmit or sell personal data. It has no accounts, no advertising, no analytics and no tracking, and it does not use the camera, microphone, location or motion sensors.
The values you type, saved calculations, calculation names and notes, projects, input presets, the current draft and your unit and display preferences are stored locally on your device using Apple's SwiftData and UserDefaults. They are not sent to us or to any third party and are not synced through iCloud by RiseSpan. They are included in your device backups according to your own iOS backup settings. Deleting a calculation or project in the app, or deleting the app, removes this local data.
PDF and CSV exports are created on your device. They leave your device only if you choose a destination in the iOS share sheet (for example Mail, Files or AirDrop); that destination's own privacy terms then apply.
The optional one-time RiseSpan Pro purchase is processed by Apple through the App Store. RiseSpan uses Apple's StoreKit on your device to check whether Pro is unlocked. We do not receive your payment details or Apple Account information. Apple's privacy policy applies to App Store purchases.
Links to this website or to your email app open only when you tap them. This website may be served by a hosting provider that keeps standard server logs.
RiseSpan is a general-audience utility and does not knowingly collect information from anyone.
If a future version changes how data is handled, this page and the App Store privacy details will be updated before that version is released. Questions: lokman782782@gmail.com.
This website uses self-hosted Umami at stats.roomivo.online to measure page visits. The tracker sends page metadata, browser language and screen size; URL query strings and fragments are excluded. It does not read form fields, identify users, set analytics cookies or record sessions. Analytics can be blocked by your browser and respects Do Not Track when available. This website measurement is separate from any data processing described above for the app.
