Privacy Policy

1. Overview

Nomina ("the App") is a local-first name day calendar for European countries, built for iPhone and related Apple surfaces such as widgets and Apple Watch views. It shows daily name days, matches them against your contacts, and lets you set up local reminders. This Privacy Policy explains what data stays on your device and what limited information may be transmitted through Apple-managed services.

2. Data we work with

Nomina processes several categories of data locally on your device:

• Contacts — accessed locally through the iOS Contacts framework to match first names against name day calendars. Contact data is read on-device only and is never uploaded, transmitted, or stored outside the Contacts database.
• Name day calendars — bundled as JSON files inside the app. No network requests are made to load or update name day data.
• Notifications — scheduled locally using UNUserNotificationCenter. There is no push notification server. All reminders are generated and triggered entirely on your device.
• User preferences — selected countries, reminder settings, widget configuration, appearance choices, and similar local settings stored in UserDefaults and App Groups.
• Favorites sync data — if you enable iCloud sync, favorite contacts and related reminder preferences may sync through your private iCloud account using Apple's CloudKit infrastructure.

This data is stored locally on your device. It is deleted when you remove the app unless iOS backup/restore mechanisms preserve it as part of your own device backup workflow.

When iCloud sync is enabled, synced favorites are stored in your Apple-managed private CloudKit container and follow Apple's iCloud retention and account controls. The developer does not operate a custom user backend for this sync.

3. Contacts access

You can revoke contacts access at any time in Settings → Privacy & Security → Contacts → Nomina. The app continues to work without contacts access — you simply will not see matched names from your address book.

4. Anonymous telemetry

Nomina uses TelemetryDeck for anonymous aggregate product analytics. These analytics help the developer understand app quality and feature usage without building personal profiles or ad targeting.

The app may send signals such as:

• App launches
• Country selection changes
• Reminder and onboarding flow events
• Widget configuration events
• Watch settings and support-surface events
• Paywall presentation and premium flow actions

TelemetryDeck also attaches limited runtime metadata automatically, such as app version, device model family, operating system version, language, region, and similar technical context described in its SDK documentation.

5. Network use

Nomina may access the network for three categories of work:

• Apple iCloud sync handling — optional favorites sync through the user's CloudKit account
• Apple purchase handling — StoreKit 2 product loading, purchases, and restore flows
• Anonymous telemetry delivery — sending aggregate product signals to TelemetryDeck

Name day data is bundled inside the app and does not require a network connection. The app works fully offline for its core nameday experience, aside from optional iCloud sync and Apple purchase flows.

6. In-app purchases

• Premium access is handled by Apple using StoreKit 2
• The developer does not receive your payment card details or billing information
• Entitlement state may be stored locally on your device to keep premium UX responsive
• Restores are handled through Apple-managed purchase records

7. No account required

Nomina does not require you to create an account. There is no login, no email collection, and no user profile maintained by the developer.

8. Data sharing

• No advertising SDKs
• No social SDKs
• No user account backend
• No cross-app behavioural advertising
• No sale of personal information

The only third-party services used by the app are Apple platform services for iCloud and purchase flows, plus TelemetryDeck for anonymous aggregate telemetry.

9. Data retention

• Local app data: stored on your device until you delete the app or clear it manually
• iCloud favorites sync: stored in your private CloudKit space for as long as you keep sync enabled and your Apple account retains that data
• Anonymous telemetry events: retained by TelemetryDeck according to its own retention policy for aggregate analytics
• Purchase records: maintained by Apple under Apple's own systems and policies

10. HealthKit

Nomina does not use HealthKit. No health data is read, written, or accessed.

11. Children's privacy

Nomina does not collect personal data from any user, including children under 13. The app does not require an account, does not build personal profiles, and does not contain advertising or behavioural tracking.

12. GDPR and CCPA

Because Nomina does not collect, store, or transmit personal data to a developer-run backend (beyond anonymous telemetry), data subject access, deletion, and portability requests generally do not apply to developer-held personal records. You control local data by managing or deleting the app on your device and Apple-account data through your iCloud settings. TelemetryDeck processes anonymous signals only; its privacy practices are described at telemetrydeck.com/privacy.

13. Your control

You can delete locally stored Nomina data by deleting the app from your device. You can revoke contacts and notification permissions independently in iOS Settings. If you enabled iCloud sync, you can also disable it from the app or your Apple account settings. Because the app does not require a developer account, there is no separate developer-side profile to request for deletion.

14. Changes to this policy

If this Privacy Policy changes, the "Last Updated" date above will be revised. Significant changes may also be reflected in app release notes. The current version of this policy is available at ios.dnesdan.cz/nomina/privacy-policy.
