Privacy

Copybook is run by Vox (@Voxyz_ai). It asks for your email only if you subscribe or sign in, and it sets no cookies.

Your email, if you subscribe

Subscribe sends one email, through Resend, with a link that confirms it was you. Until the link is opened nothing is kept, and an address gets at most one such email a day however often it is typed in. Opening the link adds the address to Vox’s mailing list at Resend, which sends the email. Every email has an unsubscribe link, and unsubscribing stops all mail; to come back, subscribe again and open the new link. To have the address deleted, message @Voxyz_ai on X.

Your email and your copies, if you sign in

Signing in is optional: it lets the tips you copy follow you to your other devices. If accounts are not switched on, Sign in says so and sends nothing. When they are, Sign in sends a one-time link to your email through Supabase, which keeps your address for the account. The tips you copied on this device join the account when you sign in, and so does each copy after: which tip, and the day you copied it.

Sign out ends your session. To have the account and its copies deleted, message @Voxyz_ai on X.

What stays in your browser

Your browser keeps, in its local storage, the tips you copied and the day of each, so the sidebar, the library and the tip pages can show them, and the tips’ short names, for the sidebar’s list. It also keeps your theme, whether Topics is folded, the agent you last picked on the MCP page and, once you sign in, your session. None of it leaves this device, except your copies and your session, which go to your account while you are signed in.

Clear my copies, in Settings, removes your copies from this browser, and from your account if you are signed in. Clearing this site’s data in your browser removes all of it.

Analytics

An analytics script loads only if analytics is switched on for the site. Switched on, it is a cookieless tool such as Plausible or Umami, which counts page visits and three events: a copy (which tip, and whether by a button, a key or a selection), a signup (which form and which page, never the address) and a click through to the post on X. None of them carries your email or anything you type.

Hosting

Copybook is served by Vercel. Like any web host, Vercel sees your IP address and the page you ask for, and keeps them in its logs for a short time to run and protect the site. Copybook writes nothing of its own to those logs.

What it does not collect

There are no ads and no other trackers. Copybook MCP, which your agent can connect to, answers each request and keeps no record of what it was asked.

Children

Copybook is made for people who build software and is not meant for children under 13 (under 16 in the EU). It does not knowingly keep a child’s email. If a child subscribed or signed in, message @Voxyz_aion X and the address will be deleted.

Earlier products

Voxyz Cloud, Studio and the Playbook have closed. If you bought one and need help, message @Voxyz_ai on X.
