Your privacy, taken seriously — by design
outils.ch is built to help you fast without harvesting your data. Here's plainly what's processed and what isn't. Nothing superfluous, nothing hidden.
Everything runs in your browser
Nearly all tools compute locally on your device: amounts, IBANs, AHV numbers, files, text… none of it is sent to or stored on a server. You can even cut your connection after the page loads — most tools keep working.
Anonymous audience measurement
To know how many people use the site and which tools are useful, we use Vercel Web Analytics and Speed Insights. These measurements are aggregated and anonymous: no advertising cookies, no individual profiling, no resale. We see trends (visits, tools opened), never who you are.
Favourites & recently opened
When you pin a tool as a favourite or open one, that's saved in your browser's local storage (localStorage), on your device only. It's never sent to a server, and you can clear it by clearing the site's data.
facturama Pro waitlist
If you leave your email to be notified about the launch of facturama Pro, it's stored in a Supabase database hosted in Europe. It is used only to contact you about facturama Pro — no resale, no other use, no unsolicited newsletter. You can request deletion at any time (see “Your rights”).
calorio account & sync
If you create a calorio account (by email or via Google) to sync your data across devices, your email address and the data you enter (profile, food log, weight tracking) are stored in a Supabase database hosted in the European Union. They are used only to provide the sync. You can sign out and request deletion of your account and data at any time.
AI coach & photo analysis (calorio Pro)
When you use the nutrition coach “Avo” or photo meal analysis, your message or photo is sent to Google (Gemini API) to generate the reply, and is not kept by outils.ch afterwards. Please don't include sensitive information. These features provide estimates, not medical advice.
Payment (calorio Pro)
Subscriptions are handled by Stripe. When you subscribe, your payment details are entered and stored by Stripe, never by outils.ch — we only receive your subscription status (active / cancelled) to unlock Pro features.
Links to the tools
Some tools open in their own app (dedicated domains). Those apps follow the same “100% in-browser” principle but operate independently; clicking through takes you off this page.
Your rights
Under the Swiss Data Protection Act (revFADP) and, where applicable, the EU GDPR, you can request access to, correction of, or deletion of your data. Data controller: Krystel Fiorbianco, Route de Derborence 28, 1976 Aven (Swiss Digital Studio). Write to us via swissdigitalstudio.ch and we'll handle your request promptly.
