Privacy Policy
Last updated: 28 June 2026
This policy explains what LatexNotes collects, why, and who it is shared with. We try to collect as little as possible.
What we collect
- Account details - if you sign up, your email address and a securely hashed password.
- Your notes - the PDFs you upload and the LaTeX and PDFs produced from them. For signed-in users these are stored in your account so you can reopen them. If you are signed out, your history is kept only in your own browser and never reaches our database.
- Basic analytics - anonymous, privacy-friendly page-view and visitor counts via Vercel Analytics. No advertising cookies, no cross-site tracking.
- Product usage - aggregate records of how the app is used: for example that a transcription succeeded or failed and the general reason why, and which features were used. This is linked only to your account id, never includes the content of your notes, and uses no cookies and no third-party trackers. We use it to find and fix what is broken or confusing.
How your notes are processed
To transcribe a page, its image is sent to Google’s Gemini API, which returns the LaTeX. This is the only purpose your pages are used for. We do not sell your data or use it to train models.
Where data is stored
Accounts and saved documents are stored in our database (hosted on Supabase/Postgres). The application is hosted on Vercel and Render. These providers process data on our behalf to run the Service.
Third parties we use
- Google (Gemini API) - performs the transcription.
- Vercel - hosts the website and provides anonymous analytics.
- Render - hosts the backend that runs transcription and compiling.
- Supabase - the database for accounts and saved documents.
The full list, including what each one processes, is on our Subprocessors page.
Keeping or deleting your data
You can delete any saved note from the “Recent notes” area at any time, which removes it from our database. To delete your whole account and its data, ask via the Support page and we will remove it.
