Privacy
Canonize keeps as little about you as it can.
Without an account
Your progress and notes are saved only in your browser, on your device. They aren't sent anywhere.
With an account
We store your email address, used only to send your sign-in links. We also store your progress: each work's status (want to, reading, finished, or watched), any rating, finish date, and page counts you add, how that changed day by day (for your charts), and your notes. If you choose a username, we store your profile too. Accounts run on Supabase (supabase.com), which stores this, and sign-in emails are sent through Resend (resend.com). Like most services, they keep short-lived security logs, such as IP addresses.
Importing
When you import from Goodreads, Letterboxd or Spotify, the file you pick is read in your browser and isn't uploaded. Only the works you choose to mark are saved, like any other progress. Last.fm and 1001 Albums Generator are read from your browser, from their public pages for the username or project you type; your Last.fm username is kept in this browser. To check albums' track lists, your browser asks Last.fm for them by album name. Works you import are saved with where they came from and the day, so friends see the import as one line in their feed.
Friends
Friends are optional. If you choose a username, anyone signed in who types it exactly sees it and the name you give, so they can send you a request. There's no list or search of everyone. Friends you accept see your favorite works, your progress, ratings, page counts, and history, and the notes you share with them. Notes are private unless you tick “Share with friends”. No one ever sees your email address. Remove a friend at any time, and they stop seeing your progress.
Suggestions
When you suggest a work, we store the canon, the name and maker you type, and when. Signed in, it's linked to your account, and we email your account's address to say what happened to it. Not signed in, you can leave an email address for that reply; we delete it once we've told you (for a canon we haven't built yet, that's when we build it). We review suggestions with the help of Claude, by Anthropic, which sees the suggestion but never your email address. The replies are sent through Resend.
Links to shops
A book's page links to Amazon, and a film's to JustWatch and Amazon, to find a copy or where to watch it. Following one takes you to their site, where their privacy policies apply; we don't tell them who you are.
Counting visits
To see how many people use Canonize, we count visits with Cloudflare Web Analytics. Cloudflare (cloudflare.com) also serves the site. When a page opens, your browser tells Cloudflare which page it was, the page you came from, and how quickly it loaded, and Cloudflare notes your type of browser and device and your country. It sets no cookies, stores nothing in your browser, and doesn't recognize you from one visit to the next or follow you to other sites. We see only totals, such as visits to each page.
What we don't do
There are no ads and no tracking cookies. We don't sell or share your information.
Deleting your information
Sign in, choose Account, then Delete account. That removes your email address and everything saved with it: your progress, notes, profile, and friends. To remove progress and notes saved in a browser without an account, clear that browser's data for this site.
