Privacy policy
Last updated: 2 November 2026
In short. We collect the minimum: your email to let you know when we open, and, if you have an account, what we need to track your progress. We do not sell your data and we do not run targeted advertising. You can have everything deleted by writing to us.
Who is responsible for your data?
The data controller is CSIDE TECHNOLOGY PLT (SSM n° 202004002735), Emporis S02-10, Persiaran Surian, Kota Damansara, 47810 Petaling Jaya, Selangor, Malaysia. Contact for any question about your data: contact@theoreme-app.com.

If you are under 15
In France, a child under 15 cannot consent on their own to receive our emails: the agreement of a parent or legal guardian is required. A parent can ask us at any time for access to their child's data or for its deletion.
Who has access?
Only the Théorème team members who need it, and our technical providers, who act on our instructions:
- Supabase (database and accounts), data hosted in the European Union
- Vercel (website hosting)
- Sentry (tracking of technical errors on the site, which may include your IP address and information about your browser)
- SendGrid (sending emails)
- Stripe (payment), when subscriptions open
Some of these providers are based outside the European Union. Transfers are covered by the European Commission's standard contractual clauses or an equivalent mechanism.
The site loads its fonts from Google Fonts servers, which receive your IP address when this happens. [Remove if the fonts are hosted directly on the site.]
Cookies
The site uses no advertising cookies and no audience measurement tools. Only the cookies needed to log in to your account are set.
Your rights
You can at any time:
- access your data and get a copy of it;
- have it corrected or deleted;
- withdraw your consent and unsubscribe, using the link in every email;
- object to processing or ask for it to be restricted;
- get your data back in a readable format (portability).
Write to us at contact@theoreme-app.com. We reply within one month. If you believe your rights are not being respected, you can contact the CNIL (cnil.fr).
Security
Data is encrypted in transit. The list of sign-ups cannot be viewed from the site: only the Théorème team has access to it.

If this policy changes, the date at the top of the page is updated. For an important change, we will let you know by email.
