1. Introduction

This Privacy Policy explains how Sarenica ("we", "us", "our") collects, uses, stores, and protects information when you use our website, desktop application, and related services. Sarenica is a personal self-tracking and research tool designed for individual users. It is not employer surveillance software, not remote-control software, and not a hidden monitoring tool.

2. Our Privacy Model

Privacy is a core product requirement, not a secondary feature.

Local-first by default: sensitive wellness and activity data is intended to stay on your device unless you explicitly enable sync or another cloud feature.
Consent-based collection: camera, keyboard, mouse, microphone, wearable, and sync-related features are controlled through user-facing settings and consent flows.
User control: you can turn features on or off, disconnect integrations, and request deletion of synced account data.
No keystroke content capture: Sarenica is designed to use keyboard activity for speed, cadence, and error-pattern metrics, not to read the content of what you type.

3. Information We Collect

Account and support information

We may collect information you provide directly, such as your name, email address, support messages, billing-related details, and account preferences.

Desktop activity and wellness signals

If you enable desktop tracking features, Sarenica may process signals such as fatigue scores, blink or eye-state events, typing-speed estimates, keyboard activity patterns, mouse activity patterns, active and idle time, session duration, and related derived metrics.

Camera-related information

If you enable camera-based fatigue features, the app may process camera input to estimate signals such as blink events, eye closure duration, face availability, and related fatigue indicators. Depending on the feature configuration, processing is intended to be performed locally on the device unless a separate cloud feature clearly states otherwise.

Wearable and integration data

If you connect services such as wearables or other approved integrations, we may access the data you authorize through those integrations in order to provide unified trend analysis and insights.

Technical and diagnostic information

We may collect crash logs, entitlement status, device/app version information, installation diagnostics, and connectivity diagnostics needed to operate, secure, and support the service.

4. How We Use Information

Provide the app experience: to calculate metrics, show trends, generate insights, and maintain your personal dashboard.
Operate local helper processes: certain desktop features may rely on local runtime components, including local backend or Python-based helper processes, to analyze signals on-device.
Sync data when you enable it: if cloud sync or an integration is enabled, we use your information to transfer, store, and restore your authorized data.
Support and security: to troubleshoot issues, prevent abuse, maintain entitlement or subscription status, and improve reliability.
Improve the product: if we use de-identified or aggregated information for product improvement, analytics, or model evaluation, we do so under the controls and permissions described in the product.

5. Microsoft Store and Desktop Permissions

The desktop app may request or use capabilities that are necessary for a packaged desktop application, including full-trust execution and device access needed for the features you enable.

Camera: used for camera-based fatigue and attention-related features only when enabled by the user.
Keyboard and mouse activity: used to compute metrics such as activity, typing speed, idle time, or interaction trends. Sarenica is not intended to capture message or document content.
Full-trust desktop runtime: packaged desktop builds may launch local helper processes required to perform on-device analysis and local service communication.
User visibility and control: these capabilities are part of the app’s disclosed functionality and are not intended to run covertly.

6. Sharing and Disclosure

We do not sell your personal data. We may disclose information only in limited situations such as:

to service providers who help us operate billing, hosting, support, or integrations, subject to appropriate contractual controls;
to integration partners when you explicitly connect and authorize those services;
to comply with law, enforce our terms, or protect rights, safety, and security;
as part of a merger, acquisition, or asset transfer, subject to applicable legal protections.

7. Retention and Security

Security measures: we use reasonable technical and organizational safeguards, including encryption and transport security where applicable.
Local storage: some information is stored on your device in local databases, caches, settings files, and runtime folders needed for desktop operation.
Retention: we retain data for as long as needed to provide the service, comply with legal obligations, resolve disputes, and enforce agreements, unless you delete it earlier where controls are available.

8. Your Choices and Rights

enable or disable supported detectors and integrations;
control sync and consent settings within the app;
request access, correction, export, or deletion of applicable personal data, subject to legal limitations;
disconnect integrations and stop future collection from those services.

9. Important Disclosures

Not medical advice: Sarenica provides informational metrics and productivity or wellness insights. It is not a medical device and does not provide medical diagnosis or treatment.
Individual use: Sarenica is designed for personal use and self-observation. Users are responsible for complying with workplace, school, or local legal rules that apply to their use of the product.

10. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will revise the effective date on this page and, where appropriate, provide additional notice.
