Privacy Policy

In short: the website collects what you type into the waitlist and contact forms. The app collects your account details and your tutoring sessions, including the audio you speak, the screenshots you share and the files you upload, because that is how the tutor answers you. We do not sell your data, we run no advertising, we use no third-party analytics, and we do not train AI models on your sessions. You can delete your history or your whole account at any time.

Who we are

Leren AI Inc. (“Leren”, “we”, “us”) is a Delaware corporation. We operate the website at tryleren.com and the Leren AI tutor. Our team works from the United States and Japan. For anything in this policy, including access and deletion requests, email us at privacy@tryleren.com.

What we collect on this website

When you join the waitlist, we collect your name and email address, and note whether you visited from a Mac or a Windows computer, so we can welcome you, tell you when Leren opens and send you the right version. Every email we send has an unsubscribe link. We do not ask for a phone number and we do not send text messages.

When you use the contact form, we collect your name, email address and message so that we can reply. The email we receive also includes your IP address and browser details, which help us spot spam and abuse.

The website runs no analytics, no advertising and no behavioural tracking, and it sets no cookies. That is why you do not see a cookie banner here.

What we collect in the Leren app

Your account. When you sign up we collect your email address, and either a password, which we store only as a bcrypt hash so that nobody can read it, or the identifier of the Google or Discord account you sign in with.

Your study profile. During onboarding you tell us your name, country, school, grade level, subjects and language preferences. You type these in yourself; we do not work them out from your location.

Your tutoring sessions. During a session we receive your spoken audio, the text you type, screenshots of the window or screen you choose to share, and any files you upload, so the tutor can hear the question, see the material and answer it. While session history is switched on, we also keep a transcript of each session, meaning what you asked and what the tutor replied, together with that turn’s audio and screenshot, so you can review it later and build notes and practice sets from it.

Your study material. We keep the explanations, notes, project files and practice sets you save, and your attempts at them.

Usage records. We record which features are used and when, and subject and difficulty labels for the questions asked, so we can see what is working and where students struggle. These records contain no question text, no IP address, no device identifier and no location.

Error reports. When something crashes or fails, the app sends us the error message, the app version, the platform and the screen you were on, so we can fix it.

Payments. When you subscribe, we keep your Stripe customer identifier, your plan and your subscription period. We never receive or store your card number; Stripe handles payment details directly.

Messages you send us. If you contact us from inside the app, we keep your message so we can reply to it. If you ask to reset your password, we send the reset email from our own mail server.

Updates. The desktop app checks our server for new versions. Like any request to a server, that check shows us your IP address and the app version you are running.

We do not ask for government identification, and we do not use your voice to identify you.

What we do not do

We do not sell or rent your personal information, to anyone, for any purpose. We run no advertising and no ad tracking, on the website or in the app. We use no third-party analytics; the usage records described above are our own, stored in our own database, and there is no Google Analytics, Mixpanel, PostHog or similar anywhere in Leren. We do not use your voice as a biometric identifier; audio is transcribed so the tutor can answer you, and that is all.

Screen sharing

Screen sharing never starts by itself. You choose the window or screen, your operating system or browser asks you to confirm, and you can stop at any time. While sharing is active, the app captures a screenshot for the turn you are asking about and sends it to be answered.

A screenshot captures whatever is in that window, including anything private that happens to be on screen. Close messages, email and anything sensitive before you share. If you tell us we have captured something we should not have, we will delete it.

Who processes your information

These are the companies that handle your information on our behalf. Each receives only what it needs to do its job.

OpenAI understands your question, writes the tutor’s answer, and turns your speech into text. It receives your spoken audio, transcripts, the text you type, the screenshots you share and text taken from files you upload. OpenAI does not train its models on what we send through its API.

ElevenLabs, and Fish Audio as an alternative, turn the tutor’s written answer into speech. They receive the text of the tutor’s reply only, and never your audio, your screenshots or your files.

Railway runs our servers, database and file storage in the United States. It holds everything the app stores, along with standard server request records that include IP addresses.

Stripe handles subscriptions and payments. It receives the payment details you give it directly, and your email address.

Sentry tells us when our server hits an error. It receives error details only: we have configured it not to send personal data, and request bodies, cookies, authentication headers and query strings are removed before anything leaves our server.

Google and Discord provide optional sign-in. If you choose one of them, they share your email address and basic account details with us. They never share your password.

Tally runs this website’s waitlist form and receives what you type into it. Formspree delivers the contact form and receives what you type into it. Loops keeps our waitlist and sends our emails to the people on it. Vercel hosts this website and sees standard server request records. Google Fonts supplies the website’s typefaces and sees your IP address as part of the ordinary request for a font file.

Training and improving Leren

We do not use your tutoring sessions to train AI models. Your audio, transcripts and screenshots are sent to the providers above for one reason: to work out what you asked and write the answer you get back. They are stored on your account so that you can review the session afterwards, and for nothing else.

If we ever decide to use session content to train or develop models, we will tell you before it starts and ask for your agreement first. We will not apply such a change to sessions recorded before you agreed.

Separately, the tutor uses your own past questions to pitch its explanations to you. That is personalisation for you alone, it never leaves your account, and you can switch it off in Settings.

Staff access

A small number of people at Leren can reach the systems that hold your information, and that access is used to run and fix the service and to investigate abuse. Because our team works from the United States and Japan, your information may be accessed from both countries. Our internal dashboard shows counts and labels only, never your transcripts, audio or screenshots.

Where your information is held

Our servers, database and file storage are in the United States, in Railway’s San Francisco region. If you use Leren from outside the United States, your information is transferred to the United States and handled under this policy and United States law.

Staying signed in

We do not use cookies. When you sign in, the app stores a sign-in token in your browser’s local storage, or on your device in the desktop app, along with small settings such as whether you asked to stay signed in. Clearing your browser or app data removes them. Google and Discord may set their own cookies on their own websites during sign-in, under their own policies.

Your controls

Session history. In Settings you can turn session history off. Doing so immediately deletes every stored tutoring session on your account, along with the subject and difficulty labels taken from them. Saved explanations, notes, project files and practice sets are kept, because they are study material you made deliberately.

Personalised teaching. Also in Settings, this controls whether the tutor uses your own past questions to pitch its explanations to you. Turning it off stops that.

Deleting your account. You can delete your account from the app. We ask for your password first if you signed up with one. Deleting cancels any active subscription and removes your account and its records.

How long we keep things

Your sessions, recordings, screenshots and uploaded files are kept until you delete them, either by deleting the session, by turning session history off, or by deleting your account. We do not delete them on a timetable.

Waitlist details are kept until we launch and you have had the chance to create an account, or until you ask us to remove them. Messages you send us are kept while we deal with your enquiry and for a reasonable period afterwards. Records we need for accounting, such as payment history, are kept as long as the law requires.

If something goes wrong

If we discover a security breach that affects your personal information, we will tell you without undue delay, explain what happened and what we are doing about it, and notify the authorities where the law requires us to.

Your rights

Depending on where you live, you may have the right to ask what personal information we hold about you, to correct it, to delete it, to object to how we use it, or to ask for a copy. To make any of these requests, email privacy@tryleren.com. We will not charge you and we will not treat you differently for asking. If you are in the European Economic Area or the United Kingdom, you also have the right to complain to your local data protection authority.

Age

Leren is made for college students and other learners aged 18 and over. We do not knowingly collect information from anyone younger. If you believe someone under 18 has created an account, email privacy@tryleren.com and we will delete it.

Changes to this policy

If we change this policy we will update the effective date above. If a change matters to you, such as a new use of your session content, we will tell account holders and waitlist members by email before it takes effect.
