Privacy Policy

This page explains what this website and the Epigraph app for iPhone do with your information. It will change as Epigraph does, and the date above shows when it last did.

This website

The waitlist

When you join the waitlist we keep the email address you typed, the time you joined, and, where the link you arrived by carried one, a short note of where it came from. That's all. It's stored with Supabase on a server in Mumbai, India, and nothing on this site can read the list back.

We use the address to send you updates on Epigraph as it's built, and to tell you when it's on the App Store. Every email has an unsubscribe link, and you can ask us to remove your address at any time.

Playing songs

Pressing play on this site fetches a 30-second preview and its artwork from Apple's servers, so Apple sees your IP address, as it does for any web request, and Apple's own privacy policy applies. Book covers are served from this site.

Cookies and logs

Today this site sets no cookies and runs no analytics. If we add either, this page will say what they collect. Our hosting provider keeps the usual short-lived server logs, which include your IP address, your browser and the pages you asked for.

The app

On your phone

Your shelf, likes, listening counts, reading sessions, preferences and reading goal are stored on your phone and go into your phone's own backups. We can't see them, apart from the numbers under Comparing with other readers.

Reading books

When Epigraph reads a book's description to find its moods, it uses Apple's on-device language model where your phone has one. The description doesn't leave your phone for this.

Looking things up

To find covers, book details and previews, Epigraph sends book titles, authors, song titles, artists and whatever you type in search to Open Library and Apple. Those services see your IP address, as with any web request, and their own privacy policies apply. Epigraph doesn't send them your shelf as a whole.

Apple Music

If you connect Apple Music, Epigraph uses it to save playlists to your library. Nothing from your Apple Music account is sent to us.

Comparing with other readers

Epigraph compares your reading with other readers, so once you have something to compare, it sends how many books you've read, how many are waiting, how many you've read this year, how many songs you've played and your best streak. Your country goes too, only if you turn that on. These numbers are kept with a random code that isn't tied to your name or device, on a server run by Supabase in Mumbai, India. No other reader can see them. Turn this off at any time from What's shared in Your stats, and your numbers are deleted. If you delete Epigraph without turning it off, they're removed after six months.

Notifications

Release-day reminders are scheduled on your phone. They're only sent if you ask for one.

Photos

If you save a share card to Photos, Epigraph asks to add it. It can only add images, so it can't see your photos.

Children

Epigraph isn't made for children under 13, and we don't knowingly collect anything from them.

Changes

If this policy changes, we'll update the date at the top of this page.
