Cookies
Few cookies, none for advertising unless we say so here.
Last updated: 11 November 2026
The app uses few cookies. Here is the full list, with what each one does and how long it stays.
Needed for the app to work
- sira_lang: your language (1 year).
- sira_free: the free book of the day (2 days).
- sira_pro, sira_own: remember that your access is open (for as long as the access lasts).
- Supabase session cookies (sb-…): keep you signed in to your account.
- Browser local storage (sira.…): progress, saved cards, questionnaire answers, points. This data never leaves your device as long as you have no account.
Audience measurement
- sira_sid: a random identifier (6 months), unrelated to your identity, to count journeys (page viewed, chapter read, offer viewed, checkout started). The IP address is not recorded.
- Vercel Analytics: cookieless traffic and performance measurement.
Advertising (only if enabled)
If we run ads, we may enable the Meta pixel to measure their effect. Meta then sets its own cookies (_fbp, _fbc) and receives standard events (page viewed, offer viewed, checkout started, purchase). You can object by blocking third-party cookies in your browser or from the ad settings of your Meta account.
Current status: [to be completed: Meta pixel enabled or not].
On the payment page
Stripe uses its own cookies to secure the payment and detect fraud (see Stripe's policy).
How to manage them
Your browser lets you delete or block cookies; the app keeps working, but you will be signed out and asked for your language again. Local storage is cleared from the browser settings.
