Privacy

Short version: you need an account to use Glossa. It holds your email address, the texts you import, and your reading: the words you’ve marked and where you are in each text. This device keeps your display settings.

Your account

You sign in with a link sent to your email address, so Glossa never has a password for you. The address is stored with your account and is only used to send you sign-in links.

Saved with your account

The texts you import (pasted, uploaded or from a link): their title and text and, for links, the address of the page and a copy of the page as the site sent it. When you import a link, our server fetches the page, so the site sees a request from Glossa, not from you. We also save which texts are in your library, which ones you’ve removed, and any names you’ve given them. Your texts can only be read from your account.

Your reading: which words you’ve marked as known or don’t know, word lists you’ve imported, how often you’ve seen and looked up each word, when you opened and finished each text, and the sentence you’ve reached. It’s saved to your account so it follows you to any device you sign in on.

When a text you import has a word our dictionary doesn’t list, we record the word itself so it can be looked up. Other learners can’t see it unless it appears in a text they can read.

If you subscribe, the status of your plan and when it renews.

Saved on this device

Your theme, reading settings and whether the sidebar is open stay in this browser’s local storage and aren’t sent to us. The browser also keeps a copy of some of your account’s data, such as your word marks, your progress and the texts you opened recently, so pages open quickly. That copy is tied to your account and is cleared when you sign out or someone else signs in on this browser.

Who handles it

Supabase stores your account and everything saved with it, and sends the sign-in emails.

DeepSeek receives the sentences of the texts you import. Its model splits them into words and writes a short meaning for each word as the text uses it. DeepSeek gets the text only, not your email address or account.

Stripe handles payment if you subscribe. We send it your email address and your account’s id; you give your card details to Stripe, not to us. Stripe never receives your texts.

Now and then we translate a text’s sentences into English with a tool we run ourselves, which sends that text to DeepSeek or to Anthropic.

We don’t sell your data or share it with anyone else.

Deleting it

Removing a text takes it out of your library; it stays in your account with your progress, and importing the same link again brings it back. Clearing this site’s data in your browser deletes your settings and the copy kept there. To delete your account and everything saved with it, write to hello@tryglossa.com from the address you sign in with.

No tracking

No analytics, no ads and no third-party trackers. Fonts are served by Glossa itself.
