QL Notes, Sheets, Slides, and Diagrams hold your research — models, theses, client decks. This page explains, precisely, where that content lives, what protects it, and what sharing and deleting actually do. No marketing gloss: each guarantee below is how the system is built.
Every doc is stored in QuantLogix's own database (Supabase Postgres, dedicated tables per doc type) inside the team channel you created it in. The database is never exposed to browsers: row-level security is enabled with no public policies, so the only path to your content is our authenticated API, which checks your sign-in (Clerk) and your channel membership on every request.
Docs are visible only to members of their channel. There is no public feed, no cross-team access, and no indexing of doc content.
Saves are checkpointed automatically — at most one snapshot per 90 seconds per doc (plus one whenever a different author takes over), keeping the last 25 versions of each doc, up to 8 MB per snapshot. You can restore any of them; restoring first checkpoints the current state, so a restore is itself reversible.
Export is built in and lossless where it matters: Sheets export to multi-tab .xlsx with formulas preserved (not just values), Slides export to .pptx including images, and Notes export as Markdown. Your work is never locked in.
Deleting a doc removes it immediately, along with its version-history snapshots and comments. Deleting a channel removes all of its docs, shares, comments, and version history. Existing share links stop working the moment the underlying doc is gone.
Doc content is sent to AI features only when you explicitly invoke them on that doc (for example, asking QL Intelligence about a note). Nothing in your docs is used for advertising, and comments and docs are processed only to provide the product — see the Privacy Policy for the complete data-practices statement.
