Privacy Policy

Account information: your name and email address. We sign you in with a one-time code sent to your email, no password, and no sign-in through Apple or Google today. Usage data: the lessons, words, and exercises you interact with, your progress, and your streaks. Purchase information: when you start a free trial or subscribe, Apple or Google handles the payment. Through RevenueCat, the service that manages our subscriptions, we receive which plan you chose, when it started, when it renews or ends, whether it is a trial, and the country of your store account. We never see or store your card or bank details. Advertising measurement: when the app is opened, an account is created, setup is finished, or a free trial or membership starts or renews, the app tells Meta (Facebook and Instagram) that this happened, with an identifier Meta's software creates for this installation of the app (not your phone's advertising ID), so we can see which of our ads work. Where the law asks for it, the app asks your permission first. We do not send Meta your name, your email, or what you are learning. Crash and error diagnostics, collected automatically through Sentry when something goes wrong, with no personal profiling. Push notification device tokens, only if you turn notifications on, which you control anytime in Profile settings or your device settings. How you found us: if you answer "Where did you hear about Poly Bla Bla?" in the app, we save your answer to your account. On Android, Google Play also tells the app which of our links led to your install (for example, a link we shared on WhatsApp), and we save that to your account too. When you tap one of our download links, we count the click with only the link name and the type of device, nothing that identifies you. We use this only to see which channels bring people to Poly Bla Bla, and we never share it. Website form data: if you sign up for launch news, contact support, or request account deletion on this website, we collect the name, email, and other details you enter in that form. Website analytics: anonymized page-view and click data collected through Vercel Analytics and through Atomic Business Kit, the platform this site runs on, so we can see how the site is used. AI features: if you agree to use Poly's AI, we collect what you type for it: an answer in a Spelling exercise that our own checks marked wrong, and your messages in Practice Talking. Voice: in the app's next update you can speak to Poly in Practice Talking instead of typing, in English, Spanish and French. Your phone's own speech recognition (from Apple or Google, under their privacy policies) turns what you say into text, and only that text comes to us, exactly like a typed message. We never record, receive or store your voice. The app uses the microphone only when you tap it, and asks your permission the first time; you can turn it off in your phone's settings and type instead. Poly's spoken replies use your phone's own voice, and the Pronunciation exercise uses your phone's own speech features: nothing from them is sent to us except your exercise result.

We use your information to provide and improve the app, respond to support and account requests, personalize your learning experience, and comply with legal obligations. Memberships are bought only in the app, through the App Store or Google Play. We use your purchase information to give you access, show your plan in your profile, remind you before a free trial ends (by notification and by email), and count how many Founders Club places are taken. We use the country of your store account to show your price in your own currency. We never collect or store card or bank details. We use what you type or say (as text) for the AI features only to run them: to check whether an answer you typed is also right, and to reply to you in Practice Talking. When an answer is checked, we keep the result so the same answer is not checked again, and to improve the list of accepted answers. In Haitian Creole, an answer the AI is unsure of may be reviewed by our team.

We work with a small set of vendors to run the app and this website: Supabase (database and sign-in), RevenueCat (subscription management), Titan (sending our emails, such as trial reminders), Sentry (crash and error reporting), Meta (measuring our ads), Expo (notifications), Anthropic (the Claude AI behind Poly's AI features), Vercel (hosting and site analytics), and Atomic Business Kit (aggregate website analytics). Apple and Google process your payments under their own privacy policies. Each vendor processes your data only on our behalf and cannot use it for its own purposes. Meta receives the limited ad-measurement data described above under its own privacy policy. We don't sell your information to anyone. When you use the AI features, Anthropic receives only what is needed to answer: the word or conversation, what you typed or said (as text), and the languages involved. It never receives your name, email or account. Anthropic does not use this data to train its models.

We retain your personal information for as long as your account is active or as needed to provide the app. You can request deletion at any time, see the section below. Practice Talking messages are deleted after 30 days. Answers checked by the AI are kept, so the same answer is not checked twice.

We implement industry-standard security measures to protect your personal data. No method of transmission over the internet is 100% secure, so we can't guarantee absolute security, but we take it seriously.

You can access, correct, or delete your data. Two ways to delete your account and data: inside the app, go to Profile then Erase My Data, or use polyblabla.com/delete-account from any browser. Both are processed within 7 days. You can withdraw consent for optional data collection at any time, for example by turning off push notifications in Profile settings or in your device settings. Deleting your account does not cancel a subscription: Apple or Google bills it, so cancel it in your store's subscription settings first. You can also turn off Poly's AI at any time in Profile; with it off, nothing you type is sent to the AI.

We use cookies and similar technologies on this website to understand how it's used. You can control cookie settings through your browser.

Our services are not directed to children under 13. We do not knowingly collect personal information from children under 13.

We may update this privacy policy periodically. We'll post the new policy on this page when we do.
