Privacy Policy
Effective September 22, 2026
1. Who we are
Dublo Learn (dublolearn.app and the learner and tutor panels under its subdomains, together the "Service") is operated by Konit LLC, a company organized in the United States ("Konit", "we", "us"). This policy explains what information we collect when you use the Service, how we use it, and the choices you have. Questions: [email protected].
2. Information we collect
Account information: your email address and the name you enter. Sign-in uses one-time codes sent to your email; we do not store a password.
Learning data: your answers, unit progress, test scores, XP, streaks, word-practice memory, difficulty ratings and the settings you choose (level, goal, reminder hour, time zone, assistant persona).
Messages with Dublo AI: the questions you type into the in-app assistant and its replies, together with the screen context the assistant needs to answer (for example the question you are looking at). Feedback you give about the app is recorded so the team can act on it.
Country: on your first visit we read the country of your network address to show prices in your currency. We store the country code only, not your IP address.
Payment information: subscriptions are processed by Stripe. Your card details are entered into Stripe's secure fields and never reach our servers. We store the card brand and last four digits, your subscription status and a record of payments and payment errors so we can support you.
Live session audio: when you join a live lesson or a speaking club, the audio of the room is recorded. Video is never recorded. The recording is turned into text and read automatically by a moderation model so that we can look into reports of harassment, unsafe or fraudulent behaviour. You are told before you join, you accept it once, and the room shows a visible notice for as long as it is recording. If you report someone from inside a room, we store who reported, the reason, and the automatic assessment of that session.
Device and usage information: browser type, screen size, the pages and screens you open and how long you stay, error reports, and, if you allow notifications, a push subscription for your device.
3. How we use it
To provide the Service: run your course, remember where you left off, adapt reviews to what you know, and show the right price for your country.
To bill you: start, renew, change or cancel your subscription through Stripe, and issue receipts.
To support you: answer questions through Dublo AI and by email, investigate errors and payment problems.
To send you what you asked for: the daily reminder at the hour you chose, the weekly summary email, sign-in codes and important account or billing notices. You can turn reminders and summaries off in Settings.
To improve the Service: understand which units are hard, which questions are confusing and where the app fails. We use this in aggregate.
We do not sell your personal information and we do not show third-party advertising.
4. Service providers
We rely on a small number of providers who process data on our behalf and under contract: Supabase (database, authentication and hosting of our application logic), Stripe (payments), Cloudflare (website hosting and delivery), Resend (transactional email, including the sign-in codes we send you), Anthropic (the language model behind Dublo AI, and the model that reviews live session transcripts for safety) ElevenLabs (audio for course content, and speech-to-text for live session recordings) and LiveKit (the live audio and video connection for lessons and speaking clubs, and the recording of that audio). These providers may be located in the United States or elsewhere; by using the Service you understand that your information may be processed outside your country.
Our sign-up and sign-in forms are protected by Cloudflare Turnstile, which checks that a request comes from a person rather than a bot. It runs silently, without showing you a puzzle, and Cloudflare processes the technical signals it needs for that check. Cloudflare does not use this data to profile you or to serve you advertising. See Cloudflare's Turnstile Privacy Addendum at https://www.cloudflare.com/turnstile-privacy-addendum/ for the details.
5. Retention
We keep your account and learning data for as long as your account exists. Deleting your account from Settings removes your profile, learning data, messages and push subscriptions. Payment records are kept for as long as we are required to keep them for accounting and tax purposes. Backups are overwritten on a rolling basis.
Live session recordings: the audio of a lesson or speaking club is deleted after 30 days. The text of that audio is deleted after 90 days. The automatic safety assessment of a session is kept for one year. If a session is the subject of an open report, its recording and text are kept until that report is closed, and then deleted on the same schedule. Analytics events about how you use the app are deleted after 90 days; only anonymous daily totals are kept after that.
6. Your choices and rights
Live session recordings: you can ask us for a copy of a recording you took part in, or ask us to delete it, at [email protected], for as long as we still hold it. We cannot delete a recording while it is the subject of an open report, because it is the evidence in that report. If you do not want to be recorded, you can choose not to join live lessons and speaking clubs; the rest of the Service does not record you.
You can read and change your name, bio, time zone, notifications and learning settings in the app. You can reset your training or delete your account in Settings at any time. You can cancel your subscription in Billing; access continues until the end of the paid period.
Depending on where you live you may have rights to access, correct, export or delete your personal information, or to object to certain processing. To exercise them, email [email protected] from the address on your account. We will respond within the time required by applicable law.
7. Cookies and local storage
The Service uses browser storage to keep you signed in, remember your theme and where you left off in a unit, and to make the app work offline as an installed app. We do not use advertising cookies. A single cookie shared across our subdomains records whether you last used the learner or tutor panel.
8. Children
The Service is intended for people aged 13 and older. We do not knowingly collect personal information from children under 13. If you believe a child has created an account, contact us and we will delete it.
9. Security
Data is encrypted in transit, access to our systems is restricted to the people who need it, and payment data is handled entirely by Stripe. No system is perfectly secure; if we learn of a breach affecting your information we will notify you as required by law.
10. Changes
We may update this policy as the Service changes. The date at the top shows the current version. If a change materially affects how we use your information we will let you know in the app or by email before it takes effect.
