Privacy & legal notice
Last updated: October 2026.
Who is responsible
This site (sitraka.lu) is published personally by Sitraka Forler, in Luxembourg. Contact: sitrakaforler@gmail.com. Hosting: Vercel Inc. (deployed to European Union regions). The data you entrust to the site (newsletter, accounts, event submissions) stays in the EU. One optional feature calls a service outside the EU; it is described below.
What data, and why
- Newsletter: if you subscribe, your email is stored at Brevo (EU-hosted) after a double opt-in (you confirm via a link). Purpose: sending you the weekly events digest. Legal basis: your consent. One-click unsubscribe in every email.
- Christian Daily: the app works without an account(everything stays in your browser). If you sign in (Google/GitHub via Supabase, EU-hosted project), we store your first name and your daily check-ins to sync across your devices. Only you can read them (row-level security). Legal basis: your consent.
- Fat Loss Tracker (/checklists/fat-loss/): your meals, weight, body-fat readings, tape measurements, sleep and profile are health data. By default they stay in your browser (IndexedDB and localStorage) and are never sent to Sitraka Forler. The answers to the health questions (pregnancy, breastfeeding, eating disorder, kidney disease, medicines) never leave the browser. Nothing you enter is sent, and the tool records no event; the tracker screen is not counted by the audience measurement, the presentation page is (see Analytics).
- Work (job-search workspace, /checklists/work/): your profile, postings, applications and notes stay in your browser (IndexedDB). The workspace requires signing in with Google or GitHub through Supabase (the same EU-hosted project as Daily), which keeps only your account identity (email, plus the name and avatar your provider returns) to guard access. None of your job-search data is uploaded. Legal basis: your consent; deletion on request at sitrakaforler@gmail.com.
- Random verse (Christian Daily, "New verse" button): when you click it, your browser requests a verse from bible-api.com, a third-party service hosted in the United States, which therefore receives your IP address, your browser's user agent and the origin sitraka.lu. No cookie, nothing else is sent; if the service is unreachable the app falls back to a local list.
- Event submissions: if you propose an event via /submit, your name and email (both optional) are stored with the submission at Supabase (EU-hosted), only to review the event and follow up if needed. Never published, never used for prospecting; deleted on request at sitrakaforler@gmail.com.
- Analytics: Vercel Analytics and Vercel Speed Insights (page views and performance metrics), aggregated and cookie-free: no individual profile, no advertising tracker. Speed Insights also measures page performance (route, browser, device type, country). The Fat Loss Tracker screen and the sign-in return parameters are excluded from both.
- Local tools (offline Daily, Checklists, agenda pins, the "one honest line" journal), stored in your browser's localStorage: what you type there is never sent to a server. Only anonymous usage counters are emitted (page view, filter used, item pinned, check-in done, link clicked), never the content you type.
How long
Newsletter email: until you unsubscribe. Daily and Work accounts: until you ask for deletion. Analytics: aggregated, no individual data retained.
Your rights
You can request access, rectification or erasure of your data, or object to its processing, email sitrakaforler@gmail.com. You may also lodge a complaint with Luxembourg's data protection authority, the CNPD.
Quizzes of the Data Analytics for Business course
The end-of-session quizzes of the course taught at the Université Catholique de Lille (sitraka.lu/teaching/data-analytics/) require signing in with a Google account; Google handles that sign-in under its own privacy policy. Signing in creates an account on this site with your name, e-mail address and profile picture as Google sends them. For each quiz we keep your answers, your score and the start and end times. Purpose: the course participation grade, and nothing else; only that grade, as part of your course mark, goes to the university. Only the instructor can see your answers and scores; Supabase hosts them in the European Union as a processor. While you take a quiz, your answers in progress are also kept in your browser, so that a reload does not lose them. Everything is deleted by 31 March 2027 at the latest, once grades are final, including the sign-in account if you use no other feature of the site. Without a Google account, or if you prefer not to use one, you take the same quiz on paper, with the same weight. The controller and the legal basis are being confirmed with the university's data protection officer. To access your data or have it deleted sooner: sitrakaforler@gmail.com.
Cookies
The site sets no advertising cookie and no third-party tracker. Signing in to Daily uses technical storage strictly necessary for the session. The Fat Loss Tracker keeps your data in your browser's storage, which is strictly necessary for the tool you use.
