Cookie & Browser Storage Policy

enorasisCore · SK.Informatics · Last updated: June 2026 · Version 10.9.106

enorasisCore (enorasiscore.eu) is an educational browser-based machine learning platform. This page explains what is stored on your device when you use our website.

Short summary: We do not use advertising or analytics cookies (e.g. Google Analytics). We use essential browser storage (localStorage) for login, preferences, and platform operation. ML training data (photos, models) stays on your computer or phone, not on our training servers.

1. HTTP cookies from our website

enorasisCore code does not set marketing or tracking cookies on enorasiscore.eu. Your banner choice is stored in localStorage (cookieConsent), not as an HTTP cookie.

2. Browser storage (localStorage)

The keys below support platform functionality. You can remove them by clearing site data in your browser (login/license state will be lost).

Name	Type	Purpose	Duration
`cookieConsent`	localStorage	Remember cookie banner choice	Until cleared
`userLanguage`	localStorage	Language preference (Greek / English)	Until cleared
`devAuthToken`, `userData`	localStorage	Account session and license/trial info	Until logout or cleared
`selectedHardware`, `rememberHardwareChoice`	localStorage	Hardware choice (micro:bit, ESP32, etc.)	Until cleared
`app_installed_version`, `app_css_hash`	localStorage	Automatic app version updates	Until cleared
`lastActivity`	localStorage	Inactive session timeout	Until cleared
`projectType`, `pwaDeclined`, `browserAlertDismissed`	localStorage	UI preferences (non-essential)	Until cleared

3. Service Worker (cache)

We use a service worker to load HTML/JS faster. This is technical caching, not user tracking.

4. Account data (login / registration)

When you register or sign in with email, our backend (Google Apps Script) receives only what is needed: email, password (hashed), and license information. This is not a browser cookie, but account processing required to run the service.

Images and ML models you train are not uploaded to our training servers — they remain in your browser.

5. Third parties

Google Sign-In (optional, on the login page): if you choose Google sign-in, Google's Privacy Policy applies. Google may set its own cookies.
Google Fonts / CDN: fonts and libraries are loaded from CDNs; we do not load analytics scripts.

6. Educational use & children

The platform is intended for educators, supervised students, and makers. It is not designed for children under 13 to register on their own without parental or school consent.

In classrooms, registration and use should be under teacher supervision or in line with your school's policy.

7. What "Essential Only" means

By essential storage we mean the data needed for the platform to work correctly, which is not used for advertising or tracking:

Login & license: devAuthToken, userData — to keep you signed in and apply your license/trial.
Operational preferences: userLanguage (language), selectedHardware (hardware choice).
Technical: app_installed_version, app_css_hash (auto-update), lastActivity (inactive session timeout), cookieConsent (your banner choice).

The following are non-essential (UI preferences) and do not affect core functionality: projectType, pwaDeclined, browserAlertDismissed.

Banner buttons:

Essential Only — the platform uses only the essential storage listed above.
Accept All — in the current release this does not enable any extra advertising or analytics cookies (there are none). The choice is simply saved so the banner is not shown again.
