Privacy Policy

Last updated: 17 October 2026

Coachers gives a child an AI Chinese-speaking relative. The relative writes to them in Chinese, listens to whatever mix of Chinese and English they say back, and helps them say it a little better. Coachers is meant to be set up by a parent or guardian, usually on the child’s own phone.

This policy covers coachers.ai and app.coachers.ai. It explains what we collect, why, which companies help us run Coachers, and what you can do about it. “Coachers”, “we” and “us” mean the operator of Coachers.

The short version

• Coachers keeps what your child says to their relative, so the relative can answer and remember them.
• An AI company writes the relative’s replies, and a speech company turns your child’s voice into text. We don’t keep the voice recordings.
• We don’t sell personal information, we don’t show ads, and nothing your child says is made public.
• Our analytics tools run only on coachers.ai, the pages that describe Coachers. None of them run in the app at app.coachers.ai, where your child talks to their relative.
• You can ask to see or delete your child’s information at any time by emailing hello@coachers.ai.

What we collect

When Coachers is set up

The sign-up form asks for your child’s name (the one the relative will call them), their age, what they like, which relative they’ll talk to, and how they read Chinese (Traditional or Simplified characters, with zhuyin or pinyin). It also records your device’s time zone, so messages arrive at sensible hours, and a founding-family code if we gave you one.

When your child talks to the relative

• Voice. When your child holds the microphone button and speaks, the recording is sent to our speech-to-text provider and turned into text. We don’t store the recording.
• The conversation. We keep the text of what your child said (including what the speech recognition heard and how sure it was), the relative’s messages, and the answers it suggested.
• Notes. After a conversation, the AI may write up to three short notes about things worth remembering, such as what your child mentioned, how they seemed and what they care about, so the relative can bring them up next time. The AI is told never to note anything that would identify or locate your child, such as a surname, an address or a school.
• Progress. The phrases the relative taught, and whether your child used them again later.
• Activity. When conversations happened and how long they lasted, and when reminders were sent.
• Notifications. If notifications are turned on, the address of your device’s push service and the keys used to encrypt messages to it.
• Safety records. If your child says something about wanting to hurt themselves, or about someone hurting them, a record of which of the two it was and when. Our Safety page explains what happens then.

When a parent creates a login

Your email address, your password (stored only as a one-way hash, never in readable form) and, if you give it, your name.

When you pay

Payments are handled by Stripe, on Stripe’s own page, so we never see your card number. We keep the Stripe customer and subscription IDs, your plan, and when it renews or ends.

Automatically

• Cookies and browser storage. A sign-in cookie keeps your family signed in on that device for up to a year. Another cookie remembers your language. A few settings are saved in the browser, such as whether English meanings are shown under the relative’s lines and whether a tip was dismissed.
• Analytics. On coachers.ai, the pages that describe Coachers, we use Google Analytics, PostHog, Grain and a simple visit counter we run ourselves to understand how those pages are used. None of them run in the app at app.coachers.ai: not on your child’s screens, the sign-up and sign-in pages or the parent page. On coachers.ai they collect things such as the pages viewed and their addresses, clicks, the device and browser, approximate location based on IP address, and a random ID stored in the browser. Grain can also record what a page shows, with what’s typed into forms and email addresses masked.
• Server logs. Our servers use your IP address to deliver pages and to limit abuse, for example by limiting how many sign-ups can come from one address. Our logs record technical events and, when something goes wrong, can include short excerpts of a conversation.

How we use it

• To run Coachers: write and speak the relative’s messages, understand what your child says, show the parent page and send reminders.
• To let the relative remember your child from one conversation to the next.
• To show you, on the parent page, a few things your child said, the phrases they learned and how often they talked.
• To take payments and manage your plan.
• To keep Coachers working and secure, prevent abuse, and understand how it’s used so we can improve it.
• To reply when you write to us, and to meet our legal obligations.

We don’t sell personal information, we don’t share it for advertising, we don’t show ads, and we don’t train AI models on your child’s conversations. The companies below process information for us under their own terms and policies.

Who we share it with

We share personal information only with the companies that help us run Coachers, and each gets what its job needs.

• Anthropic writes the relative’s messages and notes. It receives your child’s name, age and interests, the relative’s notes about them, the phrases they’ve learned, and the conversation.
• Groq turns your child’s voice into text. It receives the voice recordings.
• Microsoft provides the relative’s voice. It receives the text the relative speaks, which can include your child’s name and phrases based on what your child said. We may use Cartesia for the voice instead, which would receive the same text.
• Google, Apple, Mozilla or Microsoft, depending on your device, deliver reminders if notifications are on. Each reminder is encrypted, so they can’t read it.
• Stripe processes payments. It receives the payment details you enter on its page, the name and price of your plan, and a random ID for your family. We don’t send it your child’s name.
• Google (Google Analytics), PostHog and Grain provide analytics on coachers.ai, as described above. They receive nothing from the app.
• Hetzner hosts our servers in Finland, where Coachers’ information is stored.
• Cloudflare handles our domain name and our email routing, so email you send us passes through it.

We may also disclose information if the law requires it, to protect someone’s safety or our rights, or as part of a merger, sale or reorganisation of the business, in which case this policy continues to apply to it.

Children’s privacy

Coachers is made for children, so this section matters most. In the United States, the Children’s Online Privacy Protection Act (COPPA) gives parents of children under 13 rights over their child’s information. We give every family the same rights, whatever their child’s age.

What we collect from children, and why. Everything under “When your child talks to the relative” above, plus the name, age and interests entered at sign-up. No analytics run on your child’s screens. We use it only to run the conversation, help the relative remember your child, show the parent page, and keep Coachers working and safe, never for advertising.

Who sees it. Our team can see it, and the companies listed under “Who we share it with” process it for us. Nothing your child says is made public, and Coachers has no way for your child to message other people. The parent page shows only part of what your child said. We store the full conversation on our servers, and you can ask us for a copy. Before your child says anything, the chat screen tells them that you can see what they say, and that our team and the companies that help us can see all of it.

How Coachers is set up. Coachers isn’t taking new families right now. We closed sign-ups on 17 October 2026, and we’ll open them again once Coachers asks for a parent’s permission, in a way that checks it really is the parent, before it collects anything from a child. Families who joined before then can keep using Coachers. Their sign-up form was addressed to the parent and asked for the child’s name, age and interests, and the first conversation started as soon as it was sent. A parent login with an email address was optional. We did not verify that the person setting up Coachers was the child’s parent or guardian. If you think your child started using Coachers without your permission, email us and we’ll delete the account.

Your rights as a parent. At any time, you can:

• Review your child’s information. We’ll send you a copy, including the full conversation.
• Delete it. We’ll delete your child’s profile and everything linked to it on our servers: conversations, notes, phrases, activity, notification details, safety records and the stored audio of the relative’s lines. We keep one number that isn’t linked to anyone: a yearly count of how many times the safety protocol showed a crisis line, which California asks us to report.
• Stop further collection. We’ll stop collecting your child’s information. Coachers can’t work without hearing your child, so this means closing the account.

To do any of these, email hello@coachers.ai. If you have a parent login, write from that address; if you don’t, include your family code. Before we share or delete anything, we’ll take reasonable steps to make sure you’re the child’s parent or guardian. Some information can remain for a while afterwards in server logs, and with the companies listed above under their own retention rules. For example, Stripe keeps payment records as the law requires.

Safety

Every time your child speaks, what they said is checked for talk of wanting to hurt themselves or of someone hurting them. If the check finds it, the relative stops teaching, sends fixed messages written by people, and a card with a crisis line comes up on your child’s screen. If it was about hurting themselves, you’ll see a notice on the parent page. Our Safety page explains all of it, including what the check can miss.

How long we keep information

We keep your family’s information for as long as the account exists. There is currently no automatic deletion: we delete it when you ask us to (see “Your rights as a parent”). Voice recordings are never stored.

Security

We use encrypted connections (HTTPS), store passwords only as one-way hashes, sign the sign-in cookie so it can’t be forged, check that each family can reach only its own information, and limit repeated attempts. No system is perfectly secure, so please keep your family code private. Until you create a parent login, anyone who has the code can open your family’s Coachers on another device, including the conversation and the parent page. Once you have a login, the code only leads to the sign-in page, and it never reveals your email address.

Where information is processed

Coachers’ servers are in Finland. The companies listed above may process information in the United States and other countries.

Your choices

• Notifications. Turn them off at any time in your device or browser settings.
• Analytics. Analytics run only on coachers.ai, never in the app. There’s no setting to turn them off there yet, but browser settings and extensions that block tracking can stop much of it.
• Signing out. Signing out, or clearing cookies, removes the sign-in from that device. It doesn’t delete anything.
• Your own information. You can change your password on the parent page. To get a copy of your information, correct it or delete it, email us.
• Do Not Track. Coachers doesn’t respond to browsers’ Do Not Track signals. Google and our other analytics providers may be able to recognise your browser on other websites that use their services.

Changes to this policy

When we change this policy, we’ll update the date at the top of this page. If a change affects what we collect from children, or how we use or share it, we’ll tell parents who have given us an email address before it takes effect, and ask for permission again where the law requires it.
