Privacy & analytics
Last updated: 12 July 2026
What we record
When you accept analytics, this site records the following behavioural events via PostHog (EU-hosted):
- Pageviews (which routes you visit, not what you type)
- Quiz lifecycle: start, answer saved, submit, abandon
- Review actions: opening a past attempt, filtering the attempts list
- Admin actions (only if you are an administrator): question create/edit, status change, run publish
- A stable, randomly-generated user id and the domain part of your email (e.g. e-uvt.ro)
What we do not record
- Your raw email address or name
- The content of your quiz answers
- Session replay, keystrokes, or mouse recordings
- Cross-site browsing activity or third-party cookies
Permissions & in-app disclosures
This is a website — it requests no device-level permissions: no camera, microphone, location, contacts, or file access. Everything the platform can touch is listed here:
- Google account (sign-in only): when you sign in with Google we receive your basic profile — e-uvt.ro email, name, and profile picture. We never see your password and cannot access your Gmail, Drive, or any other Google data.
- Your Gemini API key (optional): if you save a Google AI Studio key on your profile, it is stored encrypted (AES-256-GCM) and decrypted only to call Gemini on your behalf when you request an explanation. You can delete it at any time.
- Browser storage: localStorage holds your analytics consent choice and, after consent, the PostHog SDK state.
| Cookie | Purpose | Type |
|---|---|---|
| sid | Keeps you signed in (session) | Essential |
| quiz_lang | Remembers your question language (EN/RO) | Preference |
| theme | Remembers light/dark mode | Preference |
No advertising or cross-site tracking cookies are used.
Data collection labels
A summary of every category of data the platform handles, in the style of app-store privacy labels:
| Category | What exactly | Purpose | Linked to you? | Shared with third parties? |
|---|---|---|---|---|
| Account info | e-uvt.ro email, name, profile picture, nickname | Sign-in and your account | Yes | No |
| Study activity | Exam attempts, answers, scores, timestamps | Core functionality — your results history | Yes | No |
| AI chat content | Question content and your messages when you use "Explain" | Generating explanations | Yes | Sent to Google Gemini; cached explanations may be shown to other students without your identity |
| Credentials | Optional Gemini API key | Calling Gemini on your behalf | Yes (encrypted at rest) | Only to Google, when you use AI features |
| Preferences | Question language, answer shuffle, light/dark theme | Remembering your settings | Language/shuffle: yes. Theme: stays in your browser | No |
| Usage analytics | Pageviews, quiz lifecycle events, random id + email domain | Product improvement, anonymised aggregate stats | Pseudonymous (random id) | PostHog (EU-hosted processor), only after your consent |
We collect no payment information, no location data, no contacts, and no browsing history outside this site. Data is never sold.
Why we record it
This platform is built for academic and portfolio purposes. Aggregated, anonymised usage metrics — for example daily active users, quiz-completion rate, or average time per question — may be shown publicly in the author's portfolio, CV, and associated academic write-ups. No individual user is identifiable in those aggregates; the metrics report on the user base as a whole.
We also use the same data to fix bugs and improve the study experience.
Legal basis & your choices
The legal basis for this processing is your consent, given when you clicked Accept analytics in the banner. You can withdraw consent at any time using the button below — future events will not be captured and the PostHog SDK will stop sending data from your browser.
Where data lives & how long
Events are sent to PostHog's EU region (eu.i.posthog.com) and retained
according to PostHog's default retention for this project. Your account data (email,
name) lives in our own database and is kept for as long as your account exists.
Your rights
You can ask to access, correct, or delete your data at any time — including deletion of your analytics profile and your account. Contact: raul.radulescu00@e-uvt.ro.
