Privacy Policy

1. Information We Collect

• Account Information: When you sign in via Apple, Google, or Email, we securely store your unique authentication ID, display name, and email to enable cross-device synchronization (iOS, Android) and cloud backups.
• Productivity Statistics: Focus session duration, completed focus tasks, tags, and streak milestones are stored in Cloud Firestore to provide deep work insights.
• Location Data (When-in-Use): If you choose to enable astronomical focus features such as Sacred Dawn (Brahma Muhūrta) or solar-aligned focus routines, Sanctum requests permission to access your device's location while using the app. This location data is processed exclusively on your device using high-precision astronomical algorithms to calculate local sunrise, sunset, and solar dawn intervals. Your geographic coordinates are never transmitted to external servers, never stored in our cloud databases, and never shared or sold to third parties or advertising networks. Granting location access is completely optional; if you choose not to grant permission, Sanctum seamlessly falls back to timezone-based seasonal solar estimates.
• Local Device Calendar: If you explicitly grant calendar permissions, Sanctum schedules focus blocks to your local device calendar (Apple Calendar via EventKit on iOS / Android Calendar Provider on Android). We never inspect, read, or transmit your private personal calendar entries.
• On-Device App Shielding & Focus Modes: On Android, if you choose to enable Distraction Shields and App Blocking, Sanctum utilizes local on-device system permissions (Usage Access, Accessibility, and Overlay) strictly to detect and shield designated distracting apps while a focus timer is active. No browsing history, app usage activity, or personal app content is ever recorded, stored, or transmitted off your device.

2. Zero Third-Party Advertising & Tracking

Sanctum does not include third-party advertising SDKs, behavioral cross-site trackers, or data-broker telemetry. We never sell, rent, or license your personal information or location data to third parties.

3. Data Storage and Security

All data in transit is encrypted using modern TLS 1.3 cryptographic protocols, and data at rest is encrypted with the AES-256 standard via Google Cloud infrastructure.

4. Account Deletion & Data Retention

You have unconditional control over your data. You can instantly and permanently delete your account and all associated focus history directly inside the app under Settings > Delete Account on both iOS and Android, or by submitting a deletion request to support@shindeaditya.com.
