Privacy Policy
1. Introduction & Overview
This Privacy Policy applies to the mobile application Pacer, developed as an independent, standalone offline utility. We are fundamentally committed to protecting your personal privacy.
Pacer is built upon an uncompromising Privacy-by-Design and Zero-Permission architectural philosophy. The application does not require internet connectivity, does not request access to device hardware, and does not collect, record, track, transmit, or monetize any personal information.
2. Information Collection & Processing
2.1 Zero Personal Data Collection: We do not collect, harvest, or request any personally identifiable information (PII), such as your name, email address, physical address, phone number, biometric data, IP address, device serial numbers, or advertising identifiers (GAID).
2.2 No Sensor or Health Hardware Access: Pacer does not connect to or read data from heart rate monitors, pulse oximeters, microphones, cameras, GPS sensors, or external health services. Breathing pacing is governed purely by client-side mathematical algorithms and visual timers.
2.3 100% On-Device Local State: Any preference settings (such as chosen breathing protocols, custom interval lengths) or session counters (total mindful minutes, completed cycles) are stored strictly inside the application's private, sandboxed internal storage. This data remains exclusively on your physical device and is never transmitted off-device.
3. Device Permissions Policy
The application operates with a strict Zero Dangerous Permissions Policy. The application manifest contains no user-facing or sensitive permission declarations:
- NO Internet Permission: The app has zero capability to communicate over the web or connect to remote servers.
- NO Storage Permissions: No access to external photos, media, files, or documents.
- NO Camera / Microphone: No audio or video capture capabilities.
- NO Location Permissions: Zero geolocation or GPS tracking.
- NO Contacts / Identity: Zero access to your address book or accounts.
4. Third-Party Services, SDKs & Advertising
Pacer contains zero third-party SDKs, tracking pixels, analytics frameworks, or advertising libraries:
- No analytics SDKs or third-party crash reporters.
- No social media SDKs or tracking pixels.
- No behavioral profilers, programmatic data brokers, or telemetry monitors.
5. Data Retention & Deletion Policy
Because we do not collect or maintain remote servers, we store no user data on external infrastructure.
How to Delete Your Data: You maintain absolute ownership over your local data. You can erase 100% of your local session counters and preferences at any time by:
- Navigating to your device's Settings → Apps → Pacer → Storage → Clear Storage, or
- Uninstalling the Pacer application from your device. Uninstalling removes the application sandbox and permanently destroys all local data.
6. Children's Privacy (COPPA & GDPR-K)
Pacer is fully safe for individuals of all ages, including children under the age of 13 in the United States (COPPA compliant) and under the age of 16 in the European Union (GDPR-K compliant). Because the application neither requests permissions nor collects any personal information, it presents zero risk of unauthorized disclosure or tracking for minors.
7. Security of Your Information
By operating in an air-gapped, offline manner, Pacer eliminates the primary attack vectors associated with cloud-connected mobile apps. Your local data is guarded by the operating system's native application sandbox isolation mechanisms.
8. Changes to This Privacy Policy
We may periodically update this Privacy Policy to reflect modifications in regulatory standards. Any updates will be published on this URL with an updated “Last Updated” date.
