The short version
Bloomsheet is designed to analyze spreadsheets on your device. Saku Studio does not receive a copy of the datasets you open, the charts you save or the results you calculate. The app has no advertising, no third-party analytics and no user account.
Spreadsheet content
CSV, TSV, text and Excel files are opened and processed locally. Imported datasets, saved charts, custom palettes and workspace state are stored in Bloomsheet’s local app storage. They are not uploaded to a Bloomsheet or Saku Studio server.
Bloomsheet creates a temporary file only when an export needs one. A file leaves the app when you deliberately save it, share it or choose another destination through Apple’s system interfaces.
Analysis and Apple Intelligence
Core insights and statistical tests use deterministic calculations in the app. On supported devices, optional natural-language chart and transformation tools may use Apple’s on-device intelligence frameworks. Bloomsheet does not send spreadsheet content to a Saku Studio model or server.
Purchases
Bloomsheet Pro purchases are handled by Apple through StoreKit. Apple processes payment and account information under its own privacy policy. Bloomsheet receives the product and entitlement status needed to unlock features; Saku Studio does not receive your payment-card details.
Deleting your data
You can remove individual datasets and saved charts inside Bloomsheet. Removing the app and its data from your device removes the local Bloomsheet workspace, subject to any device backup you have chosen to keep with Apple.
