Privacy policy

This page explains what Arc Deck collects, why, and what you can do about it. Arc Deck is made by xGravity and run by Alchemic Graph ("we").

On this website

• Early access list. If you join, we store your email address and the page you joined from. We use it only to tell you about your Arc Deck account.
• The live room. While you're on the site, your browser gets a random id and shares your pointer position with other people on the site at that moment. It isn't linked to you and isn't stored.
• Your browser. The site keeps one setting in your browser so it can skip the intro on your next visit.

We don't use advertising trackers, and we don't sell your information.

In the Arc Deck app

• Your account. Your email, your name and an optional logo.
• Your decks. The files you upload and the slides made from them. Your decks are yours. Viewers see them only through links you share.
• Viewing stats. When people view a deck that someone shares with them, we record when it was opened, time spent on each slide, return visits and shares, so the person who shared it can see them. If you were sent a personal link, those stats are tied to your name. Viewers are told on the deck that views are recorded.

Who handles the data

The site is hosted on Netlify. Accounts, decks and the early access list are stored with Supabase. Account emails are sent through Resend. Each handles data only to provide its service.

Your choices

You can ask us to show you or delete anything we hold about you. Email hello@arcdeck.co. Deleting your account deletes your decks.

Changes

If this policy changes, we'll update this page and the date below, and tell account holders about any big change by email.
