Cadence Privacy Policy

Last Updated: October 2026 | Effective for: Cadence iOS Application
Core Principle: Cadence is built on a strict local-first architecture. All your habits, reminders, and plan notes reside exclusively on your personal device. We require no user accounts, perform zero data collection, and include zero third-party tracking or analytics SDKs.

1. Local-First Architecture & Data Storage

2. Zero Data Collection & No Tracking

In accordance with Apple's Privacy Manifest (PrivacyInfo.xcprivacy):

3. Apple System Permissions & APIs

4. Encrypted Backups & Export

Exported backups are encrypted locally using AES-GCM-256 with a key derived from your user passphrase. The developer has no access to your passphrase and cannot restore forgotten keys.

5. On-Device Natural Language Parser

Natural language parsing is executed entirely on-device using structured syntactic algorithms, without sending user input to cloud LLMs or remote APIs.

6. In-App Purchases & Subscriptions (StoreKit 2)

Cadence Pro subscriptions are processed securely by Apple's StoreKit 2. All billing and card information is handled directly by Apple under its privacy policy. The developer only receives anonymous cryptographic receipts to unlock Pro features.

7. Privacy-Safe Diagnostics

When generating diagnostic logs, sensitive task titles, notes, and passphrases are automatically redacted by the on-device privacy scrubber.
