Privacy Policy
Last updated: September 23, 2026
Overview
RetinaReset is designed with minimal data collection. This policy describes what we process and why.
Data Stored on Your Device
The App stores locally on your device:
- Protocol progress, streak, and settings
This data stays on your device unless you explicitly use features that contact our servers.
Data Sent to Our Servers
AI Assistant
When you use the AI chat, your messages are sent to our API and forwarded to our AI provider (Azure OpenAI or OpenAI) to generate replies. Do not share personal health identifiers you are not comfortable processing through third-party AI services.
Website analytics (Google Analytics 4)
On retinareset.com, Google Analytics 4 is optional. The rule depends on the country of your IP address.
- United States and other regions outside the EU, EEA, United Kingdom, and Switzerland: analytics may run until you opt out. You can dismiss the notice; the lasting control is Cookie settings.
- EU, EEA, United Kingdom, and Switzerland: analytics stays off until you accept it. Reject is on the same banner. You can withdraw that choice on Cookie settings.
We do not sell or share personal information, and this site does not load advertising cookies. A Global Privacy Control signal is treated as an opt-out of sale or share.
Events are page views and similar usage data. We do not intentionally send your name, email, or health information to Google Analytics. Cookie names and lifetimes are in the Cookie Policy.
The app does not use this website banner. App data is described in the other sections of this policy.
Location
The App may request location permission to calculate local sunrise and sunset for the circadian protocol and to estimate current sky conditions (clear vs overcast) for the morning light session.
Your coordinates are not uploaded to our own servers. To compute these values, approximate coordinates are sent directly from your device to third-party services — a sunrise/sunset provider (sunrise-sunset.org) and a weather provider (Open-Meteo) — which return the requested times and cloud-cover data under their own privacy policies. When these services are unavailable, the App falls back to an on-device approximation.
Notifications
Reminder notifications are scheduled locally on your device. We do not receive the content of your reminders.
Data Retention
We do not maintain user accounts. AI chat messages are processed to generate replies and are not retained for marketing purposes beyond what our AI provider requires for service operation.
Children's Privacy
The App is not directed at children under 13.
Changes
We may update this Privacy Policy. Material changes will be reflected in the App.
