Privacy Policy

latexci is designed to collect as little data as possible.

Tools that run entirely in your browser (LaTeX Preview, LaTeX Diff, Table Generator, Word → LaTeX .docx conversion): your LaTeX source, uploaded files, and generated output never leave your device. Nothing is sent to our servers.

PDF export: your LaTeX source is sent to latexonline.cc, a third-party compile service, to generate a PDF. No account information or personal data is transmitted — only the raw LaTeX text.

Account creation (optional): if you create an account, we store your email address, a hashed password, and the documents you choose to save. This data is stored in Supabase (EU region).

Analytics: we may collect anonymised page-view counts and referrer data via Vercel Analytics. No cookies are set for this purpose.

Payments: if you upgrade to a paid plan, payment details are handled entirely by Stripe. latexci never sees or stores your card number.

Email address: to authenticate you, send transactional emails (password reset, receipts), and contact you about your account.

Saved documents: to display them in your dashboard and sync them across your devices.

We do not sell, rent, or share your personal data with third parties for marketing purposes.

We use a single, essential session cookie for authenticated users. This cookie stores your login state and expires when you sign out.

We do not use advertising cookies, tracking pixels, or third-party analytics cookies.

Supabase — database and authentication provider. Data is stored in the EU (West region). See supabase.com/privacy.

Vercel — hosting and edge network. See vercel.com/legal/privacy-policy.

Stripe — payment processing. See stripe.com/privacy.

latexonline.cc — PDF compilation (only when you click the PDF export button). Their privacy policy is available at latexonline.cc.

Your account and saved documents are retained until you delete your account.

You can delete your account at any time from your dashboard settings. All associated documents are permanently deleted within 30 days.

If you are located in the European Economic Area (EEA), you have the right to access, rectify, erase, restrict, or port your personal data.
