Privacy

What this service knows about you, why, and how to make it forget.

Last updated 19 September 2026.

Who is responsible

AnimeLang is run by a sole proprietor in Texas, United States. Questions about your information, and requests to see or delete it, go to hello@animelang.com.

If you join the waitlist

Your email address, and the language you said you would like to learn if you chose one. That is all: no account is made and nothing else is recorded with it. It is used to tell you when AnimeLang opens, and for nothing else. To be taken off the list, write to hello@animelang.com.

If you have an account

• Your email address, so you can sign in and so we can send you a link to confirm it or to choose a new password. If you joined with an invitation, which one.
• Your notebook — the words you're learning, the groups they're in, your conversations and lessons with their transcripts, the tutor's notes about your mistakes, and your practice tally; and which languages you're learning and which language the app speaks to you in. This is the service; without it there is nothing to come back to. The two languages are also noted when you sign up, so that whichever device you first open the app on starts in them.
• What each request cost — the date, which part of the app asked, how much text was involved and the price of it. This is how a monthly allowance is enforced. It does not include what you wrote.
• Whether you are subscribed — the subscription's status and when the paid month ends, and the reference Stripe gives you. The payment itself is described below.
• Your totals and milestones — your XP, your XP on each of the last fourteen days, your days in a row, and how many words you've learned in each language, kept up to date as you practise, with your time zone so days are counted as yours; and when those reach certain numbers (1,000 XP, 100 words, 30 days), which one and when. Your profile shows the totals and the last seven days; the milestones go to the people who follow you. See below.

If you use Friends

Friends is optional. It starts when you pick a handle, and until you do, nobody can find you, see your profile or follow you.

• Your handle is how people find you: by typing it exactly, by scanning your code, or by coming across it in the list of someone who follows you or whom you follow. There is no search. Your email address is never shown to anyone.
• Your profile can be opened by anyone signed in who has your handle. It shows your handle, the month you joined, your XP, your XP on each of the last seven days, your current streak, how many words you've learned in each language, and who you follow and who follows you — nothing else. Not your words themselves, and not your conversations, lessons or notes. Your time zone isn't shown.
• Following is one-way. Anyone who knows your handle can follow you without asking, and then sees each new milestone of yours in their feed. You can see who follows you, and remove anyone; someone you remove can't open your profile or follow you again unless you let them, and you're left out of any list they look at.
• Who you follow, up to 100 people, and who follows you.
• Hearts: who hearted which milestone. On yours, you see who hearted it; everybody else sees only how many.

When you pay

The sale is made through Link, Stripe's merchant-of-record service, on Stripe's own checkout page. There you give Link your name, email address, billing address and card or other payment details; Link also sees your IP address. It uses them to take the payment, to work out and pay the sales tax or VAT that applies where you are, and to prevent fraud, under Link's privacy policy. No card number ever reaches this service. We can see, in Stripe's dashboard, the name, email address and billing address you gave at checkout, and the invoices.

Where your writing goes

When you talk to a character, ask for a hint, or have your answer checked, what you wrote is sent to a language-model provider to produce the reply. It is sent for that purpose and no other. We do not use your writing to train anything.

Some requests contain nothing about you at all — the sentences that practise a word, the words that go with another word, a recording of a word being read aloud, the app's own notes put into your language. Those answers are kept and reused for everyone learning that language, because they would otherwise be generated again identically. Nothing you typed is ever shared this way.

Who else is involved

• Supabase — stores your account, your notebook and the waitlist, in a data center in Oregon, United States.
• Cloudflare — serves this site, runs the service between the app and the model provider, and forwards mail sent to hello@animelang.com.
• Retool — the dashboard we run the service from. It shows us the waitlist, the invitations, and each account's email address, plan and usage, but nothing in your notebook.
• Anthropic — the language model that writes the replies, and so receives what you write in the app, as described above.
• Resend — sends your invitation off the waitlist, and the emails that confirm your address and reset your password.
• Stripe and Link — take the payments and handle the tax on them, as described above.
• Google — mail you send to hello@animelang.com is read in Gmail.
• Microsoft — Azure AI Speech reads words aloud when your device has no voice for them, as described below.

Words are read aloud by your device's own voices when it has one for the language. When it doesn't, or you choose the server's voice in Settings, Microsoft Azure AI Speech reads them instead. It receives only the text to be read — a word, an example sentence, or a line the tutor or a character says, which can include something you told them, such as your name — and never your account details. Each recording is kept and reused for everyone who needs the same words.

Like any website, these services see your IP address when you connect, and Supabase and Cloudflare keep short-lived logs of requests for security and to find faults.

Cookies

None for advertising or analytics. Your browser stores your sign-in so you stay signed in, plus small preferences — chosen voice, how the word list is sorted, the language you read the site in. Those never leave your device, except the language, which is kept with your notebook once you have an account. Stripe's checkout page sets its own cookies, for payments and fraud prevention.

Taking it with you, and deleting it

Settings has an Export button. It writes one file containing everything: every word, group, conversation, lesson and note. It works whether or not you are still subscribing. Friends isn't in it: your handle, who you follow and who follows you stay here.

To delete your account and everything in it, write to hello@animelang.com from the address you signed up with. Everything is removed, apart from the payment records Stripe and Link must keep for tax purposes. You can ask Link directly to delete what it holds.

Children

This service is not intended for children under 13, and accounts are not knowingly created for them.

Changes

If what is kept or who it is shared with changes, this page changes with it and you are told by email before it takes effect.
