Privacy Policy

Effective Date: June 11, 2026•Last Updated: November 6, 2026•Developer: 3nsofts

The Short Version

Sheetforge does not collect, transmit, or sell any personal data or spreadsheet content. Your data stays on your device unless you choose to save or share it elsewhere. We have no spreadsheet servers, no analytics, and no accounts.

1. Overview

Sheetforge is a spreadsheet application for macOS, iOS and iPadOS developed by 3nsofts. We built it with a single guiding principle: your data is yours and stays on your device. Sheetforge does not collect, transmit, store, or sell any personal data or spreadsheet content.

2. Data We Do Not Collect

Sheetforge does not collect, transmit, or store any of the following:

  • Spreadsheet content (cell values, formulas, file names)
  • Personal identifiers (name, email, Apple ID)
  • Usage analytics or telemetry
  • Crash reports sent to 3nsofts servers
  • Device identifiers or hardware fingerprints
  • Location data
  • Contacts, calendar, or photos
  • Clipboard contents (never read in the background)

3. Data That Stays On Your Device

Sheetforge stores the following data locally on your device:

3.1 Workbook Files

On Mac, workbook files are read from and written to locations you choose, with local file-access bookmarks where needed. On iPhone and iPad, imported files become local native working copies in the app's storage, leaving the imported original unchanged. Recent-file metadata is stored locally. You can explicitly choose a Files provider or sharing destination when exporting; that provider handles any upload under its own policy. Sheetforge does not automatically synchronize workbooks to a developer server. Your own operating-system backups may include app data according to your Apple backup settings.

3.2 Application Preferences

Application preferences and recent-file information use Apple's local device storage, including UserDefaults. Available preferences vary by platform. Sheetforge does not send these preferences to 3nsofts or operate a preference synchronization service.

3.3 Autosave and Recovery

Saving and recovery data remain local: Mac saves to the working workbook location, while iPhone and iPad save native working projects in app storage. These saves do not replace an imported mobile source file. No recovery copies are sent to 3nsofts.

4. AI Features (Apple Intelligence)

Sheetforge's AI Assistant uses Apple's on-device Foundation Models framework (Apple Intelligence). This means:

  • All AI processing happens entirely on your device — no data is sent to 3nsofts servers or any third-party AI service.
  • Spreadsheet content passed to the AI (formula suggestions, data analysis) is processed locally by the Apple Intelligence system model and is subject to Apple's Privacy Policy.
  • AI results are used locally in the app; 3nsofts does not receive your prompts, selected spreadsheet content or results.
  • AI features require macOS 26, iOS 26 or iPadOS 26 or later, compatible hardware, Apple Intelligence enabled and Apple's on-device model available. Apple controls model setup and availability by device, software, language and region. Spreadsheet editing and calculation remain available without AI.

5. No Account Required

Sheetforge does not require you to create an account, sign in with Apple, or provide any personal information to use any feature of the app, including AI features.

6. Network Access

Sheetforge does not make outbound network connections. The app:

  • Does not contact any 3nsofts server
  • Does not use analytics SDKs
  • Does not check for updates over the network (updates are delivered through the App Store)
  • Does not load remote content into spreadsheets

Apple handles App Store downloads, updates, licensing and system model setup under its own policies. If you explicitly open or export a file through a cloud storage provider, or share a file, Apple's system interface and the provider you choose handle that transfer. No spreadsheet content is sent to a 3nsofts backend.

7. File System Access

Sheetforge requests access to files only when you explicitly open or save them using Apple's standard Files picker or Mac Open/Save dialogs. It does not scan your file system, access files outside your selection, or maintain broad file system access.

8. Sandboxing

Sheetforge uses Apple's application sandbox protections on each platform. The operating system limits access to other apps and files beyond the app's own storage and the file access you grant through system interfaces.

9. Children's Privacy

Sheetforge does not collect any personal data from anyone, including children under the age of 13. No account creation, data submission, or personal information is required or possible.

10. Third-Party SDKs and Frameworks

Sheetforge uses no third-party analytics, advertising, or data-collection SDKs. It relies solely on Apple's first-party frameworks (SwiftUI, Swift Charts, Foundation, Apple Intelligence).

11. App Store

Sheetforge is distributed through the App Store. Apple handles all transactions and download processes. Apple's privacy policy governs data collected during that process. See apple.com/legal/privacy.

12. Changes to This Policy

If we update this Privacy Policy, the new version will be published on our website and the updated date will be revised at the top of this document. Because Sheetforge collects no data, changes to this policy will typically reflect new Apple platform capabilities or clarifications — not new data-collection practices.

Sheetforge is designed so that the strongest privacy guarantee we can make is also the simplest: we never see your data because it never leaves your device.
