SettingsCommon questions about Lexon and how your data is handled.
Your documents stay in your library until you delete them. There is no expiration or time limit. The only automatic cleanup is for version history: each document keeps up to 50 previous versions; older versions are pruned automatically.
All your documents, folders, tags, and images are stored locally in your browser using IndexedDB. Nothing is sent to or stored on our servers. Your document content never leaves your device unless you explicitly export or share it. We use Google Analytics for anonymized usage statistics (e.g. page views); see our Privacy and Cookie policies for details.
We use Google Analytics to collect anonymized usage data (pages visited, time on site, etc.) to improve Lexon. Your document content is never sent to Google or any analytics service. You can opt out using the Google Analytics Opt-out Browser Add-on or your browser settings.
Yes. Lexon is offline-first. After you load the app once, it works without an internet connection. Your documents are stored locally in your browser, so you can write, edit, and organize your notes even when you are offline.
You can import DOCX (Word) files and convert them to Markdown. You can export your documents as Markdown (.md), HTML, or PDF (via print). All editing is done in Markdown with live preview and a rich editor (TipTap) option.
Yes. Since documents are stored in your browser, clearing site data (including IndexedDB and localStorage) will remove all your saved documents, folders, and preferences. Export any documents you want to keep before clearing your browser data.
Yes. Lexon is free to use. There are no subscription fees or premium tiers. Create documents, organize them in folders, use tags, and export in multiple formats at no cost.
Yes. Lexon supports LaTeX math (KaTeX) for formulas and syntax-highlighted code blocks. You can write equations and code snippets with proper formatting in your Markdown documents.
Markdown is a lightweight markup language that lets you format text with simple syntax (e.g. # for headings, ** for bold). A Markdown editor like Lexon helps you write in Markdown with live preview, export to other formats, and keep your content in a future-proof, plain-text format that works across platforms.
