Privacy Policy

Nummeric is built so that nothing about your calculations leaves your device unless you explicitly choose to share. This isn't a marketing claim — it's the architecture. There are no analytics SDKs, no tracking pixels, no third-party libraries that phone home.

Data We Collect

None. Nummeric does not collect, transmit, or store any personal data on external servers. We have no analytics, no crash reporting services, no user accounts, and no server infrastructure that receives your data.

Data Stored on Your Device

Nummeric stores the following data locally on your device:

• Calculation history — your past calculations and results
• Notebooks — your math notebook documents
• Scratchpad — saved values and notes
• User constants — custom constants you define
• Preferences — your chosen theme, settings, and layout configurations

All of this data is stored using Apple's SwiftData framework on your device. It never leaves your device unless you explicitly enable iCloud sync or use the share function.

iCloud Sync

If you enable iCloud sync (off by default), your calculation history, notebooks, and scratchpad are synced across your Apple devices using Apple's CloudKit infrastructure. This data is encrypted in transit and at rest by Apple. Neogy LLC does not have access to your iCloud data. You can disable sync at any time in Nummeric's settings.

Apple Intelligence Features

Nummeric uses Apple's on-device FoundationModels framework for features like Ask Nummeric (AI chat), smart paste, and history insights. All AI processing happens entirely on your device. No data is sent to Apple's servers, Neogy LLC's servers, or any third party for AI processing.

Camera & Microphone

Nummeric may request access to your camera (to scan equations and receipts) and microphone (for voice input). These features process data entirely on your device:

• Camera — images are processed on-device and are not stored or transmitted
• Microphone — audio is processed using on-device speech recognition and is not stored or transmitted

You can revoke these permissions at any time in iOS Settings.

Location

Nummeric requests your location once during initial setup to auto-detect your local tax region for the sales tax calculator. Your location is used momentarily and is never stored or shared.

Face ID / Touch ID

Nummeric offers biometric authentication to protect your calculation history. Biometric data is handled entirely by Apple's Secure Enclave. Nummeric never has access to your biometric data.

Currency Exchange Rates

The unit converter fetches live currency exchange rates from a public API. This is the only network request Nummeric makes. No personal data or device identifiers are included in these requests. Rates are cached locally for offline use.

Third-Party Services

None. Nummeric contains zero third-party SDKs, zero analytics frameworks, zero advertising libraries, and zero social media trackers. The only external dependency is the currency rate API mentioned above.

Children's Privacy

Nummeric does not collect personal information from anyone, including children under 13. The app is safe for all ages.

Changes to This Policy

If we change this policy, we will update the date at the top of this page. Because Nummeric collects no data, meaningful changes to this policy are unlikely.
