bule.ai helps you practice speaking English with a friendly AI tutor. You talk, the tutor listens, and — if you turn your camera on — it watches you and replies like a patient teacher. This page explains, in plain words, what we do and do not do with your information.
What we never do
- Your voice is never recorded. Your audio is processed in real time so the tutor can understand you and reply. At most about 30 seconds is briefly held in memory during a turn, then discarded. Nothing is written to disk.
- Your camera is never recorded. Turning the camera on is optional. If you do, the tutor looks at the current video frame in real time. Frames are discarded immediately after use.
- Your audio and video are not sent to third-party AI companies. Speech recognition, the tutor's AI model, and its voice all run on our own servers. Only text is ever sent to an outside AI provider, as listed in section 4.
- No advertising, no data sales. We do not show ads, we never sell or rent your personal data, and we run no third-party analytics trackers on our sites.
1. Who we are
bule.ai is operated by Iridian Labs, LLC, a Delaware limited liability company. We run this website (bule.ai), the app at app.bule.ai, and the bule.ai mobile apps. We are the data controller for your information. If you have any questions, email us at [email protected].
2. What we collect
Unless we say otherwise, we collect the items below only for signed-in users, and only what we need to run your tutor.
- Account. Your email address, used to send you a one-time code to sign in.
- Conversations. Text transcripts of what you and the tutor said, plus metadata such as when a session happened and how long it lasted.
- Memory. Short facts the tutor keeps about you between sessions (for example, "preparing for IELTS"), extracted from your transcripts.
- Recaps and Words. After a session, a short Recap of how you did, the English words you used or were reaching for, and your daily challenge results. With Premium, your Recap also has Notes the tutor wrote after reading your conversation back.
- Profile. The answers you give in the few questions we ask before your first session: what to call you, your native language, how well you speak English, what you are practising for, and how you heard about us. We do not ask your age. We also record the country your connection comes from, which we read from the network rather than asking you. We use these to make your first conversation personal and to understand who is using bule.ai; the tutor itself only ever sees your name, your goal, and your native language.
- Using bule.ai without signing in. If you practice without an account, we do not keep transcripts or memory — the conversation is gone when it ends.
- Payments. In the mobile app, Premium is bought through the app store you installed bule.ai from — Google Play on Android, or the Apple App Store on iPhone and iPad — which handles the payment as seller. The store and RevenueCat (which manages subscriptions for us) share with us only what we need to run your subscription, such as an anonymous purchase ID, the product, the store country, and subscription status. On the web (app.bule.ai), payment is handled by Stripe, and Link (a Stripe company) is the seller. You give your name, billing address, and payment details to Stripe and Link at checkout, not to us. We keep the subscription record Stripe sends us (your Stripe customer and subscription IDs, the plan, its status and dates, and Stripe's reference to the saved payment method, not the card itself). Either way, we never see your card number.
- Technical. Standard server and error logs, which may include your IP address and device or browser information.
- Early-access form. If you fill out the early-access form on our marketing site, we collect the phone number you submit.
3. How we use your information
We use your information to:
- run the service;
- let the tutor remember you across sessions;
- keep a long conversation on track, by summarising its earlier part;
- write your Recap after each session, including the Notes if you have Premium;
- show you your conversation history;
- fix errors and keep the service reliable;
- respond to your support requests;
- send you service emails, such as sign-in codes and important account or billing notices. We do not send marketing spam.
4. Service providers we rely on
We use a small set of trusted companies to run bule.ai. Each one receives only what it needs to do its job.
| Provider | What it does | What it receives |
|---|---|---|
| Supabase | Database and sign-in | Email, transcripts, memory facts, profile answers |
| OpenRouter, which passes the request to OpenAI | Reads conversation text to (1) pick out the tutor's memory facts after a free conversation, (2) write the Notes on your Recap if you have Premium, and (3) summarise the earlier part of a long conversation so the tutor can keep up | Transcript text only (no audio or video), plus the memory facts the tutor already has when picking out new ones, and your native language and English level when writing a Recap. We set OpenRouter to use only OpenAI's own service and only providers that do not keep or train on this data. |
| Google Play or the Apple App Store | Payments, taxes, and refunds for Premium bought in the app | Billing details you give the store at checkout |
| Stripe, Inc. and Link (a Stripe company) | Checkout, payments, taxes, receipts, and refunds for Premium bought on the web. Link is the seller of these purchases and may contact you about your order. | Your email address and account ID, plus the name, billing address, and payment details you give at checkout |
| RevenueCat | Manages Premium subscriptions and tells us their status | Your account ID, purchase and subscription status, store country |
| Sentry | Error tracking | Error reports, which may include your account ID and email |
| Resend | Sends our emails | Your email address, and early-access phone number notifications |
| Cloudflare | Hosts our websites and routes our email | Standard web traffic data |
| Grafana Cloud | Monitors that our servers are healthy | Server metrics and technical logs (never conversation content) |
| Akamai/Linode | Runs our self-hosted call server | Your audio and video pass through it live during a session (not stored) |
| Our own GPU servers | Speech recognition, tutor AI, and voice synthesis | Live audio, video frames, and conversation context during your session (not stored) |
These providers may process data in other countries (for example, the US or the EU). We use them under their standard data-protection terms.
5. How long we keep your data
We keep your transcripts and memory facts while your account exists, so the tutor can remember you. You can see every memory fact on your Profile screen and delete any of them at any time. You can delete your whole account yourself: open the Profile tab in the app and tap Delete account, or email [email protected]. We delete your transcripts, memory, and account data. Logs and error reports expire on their providers' standard short schedules. See Delete your account for the steps, exactly what is deleted, and what is kept and for how long.
6. Your rights
You can access, correct, delete, or export your data, or object to how we process it. Just email [email protected] and we will answer within 30 days. We honor these rights for everyone, regardless of country, including under the GDPR where it applies.
7. Children
bule.ai is not for children under 13, and we do not knowingly collect their data. If we learn that we have, we delete it. Users aged 13 to 17 need a parent or guardian's permission to use bule.ai. We do not ask your age when you sign up, so we do not knowingly record that any user is a minor. Guardians can contact [email protected] about their child's data.
8. How we protect your data
We encrypt your data in transit using TLS, and we limit access to only what is needed to run the service. Still, to be honest, no system is perfectly secure.
9. Changes to this policy
If we make material changes to this policy, we will announce them on the site — and by email to account holders — before they take effect.
