Privacy policy

1. Who we are

Hi Speakers is developed and operated by Thiago Luiz Rodrigues, an individual developer based in the United States (“we”). We are responsible for the data described here. For any question or request about your data, write to hispeakers01@gmail.com.

2. Data we collect

We only collect what the app needs to work:

• Account: your name and email, which come from Apple or Google when you sign in. We do not receive or store your Apple or Google password.
• Preferences: app language, native language, appearance (light or dark) and time zone.
• Your content: the decks and cards you create (phrases and words), the idea requests you make to Isabella and the reference audio of each card, generated with a synthetic voice.
• Your progress: your practice history, with scores, the sounds and words you got wrong, and the grammar patterns behind each mistake.
• Anonymous technical device data: operating system and version, device model, memory range, whether the AI model downloaded and ran well, and a random installation code. This report has no name, email or account, and it does not store your IP address or the exact time.
• Profile photo: if you choose one, it stays on your device only.

3. What stays on your device

Your voice is recorded and scored on your phone. The audio of your recordings is never sent to us or to anyone else. The AI model that scores pronunciation runs on the device, and so does the speech recognition of Say it in English.

4. What we use data for

We do not use your data for advertising and we do not sell it.

• Making the app work: signing in, storing your decks and cards, scoring and showing your progress.
• Generating the content you ask for: card ideas, translations, explanations of your mistakes, sentences and word explanations.
• Improving the app with the anonymous technical data, for example deciding which devices to support.

5. Who we share it with

We may also share data if the law requires it.

• OpenAI: receives the text needed to generate content: the topic you ask Isabella for, the phrases and words on your cards, the phrase you type and the transcript (text) of what you said in Say it in English. It also generates the reference voice from the text of the phrase. It never receives the audio of your recording.
• Amazon Web Services (AWS): where the server, the database and the cards' audio files are, in data centers in the United States. If you use the app from another country, your data is sent to and processed in the United States.
• Cloudflare: delivers the AI model download the first time you open the app. As with any download, Cloudflare sees the IP address of whoever downloads.
• Apple and Google: for sign-in. If you use Sign in with Apple, when you delete your account we revoke access in Sign in with Apple.

6. Shared reference voice

To avoid generating the same voice many times, we keep the synthetic audio of each text in a cache shared among users. It is not linked to any account: the file is identified only by a signature of the text. Even so, the text may have been written by you, so avoid putting personal data (such as your full name, phone number or address) on cards. Because the cache has no owner, it is not deleted when you delete your account.

7. How long we keep it

We keep your data while your account exists. When you delete a card or a deck, its data and audio are deleted. The anonymous technical device data is not linked to anyone, so it is not part of account deletion.

8. Your rights and how to delete your account

You can delete your account at any time, inside the app, on the profile screen. Deletion is permanent and removes your decks, cards, attempts, preferences, the audio of your cards, your login sessions and your user, and revokes access in Sign in with Apple. An access token already issued may work for a few more minutes, but there is no data left for it to open.

If you cannot use the app, or want to ask for a copy, a correction or deletion of your data, write to hispeakers01@gmail.com. We answer within 45 days. If you live in California, you have the right to know what personal information we hold, to have it corrected and deleted, and not to be treated differently for using these rights. We do not sell your personal information and we do not share it for advertising. If the law of your country grants other rights (such as the GDPR in Europe or the LGPD in Brazil), they apply here too.

9. Security

The credentials we store are encrypted, the connection to the server uses HTTPS and the keys to our services are kept outside the app and the code. No system is perfect, but we treat data protection as part of the product.

10. Children

Hi Speakers is not directed to children under 13 and we do not knowingly collect their data. Signing in requires an Apple or Google account, which those companies reserve for people who meet their own age requirements. If you think a child under 13 created an account, write to hispeakers01@gmail.com and we will delete it.

11. The website

The hispeakers.com website uses no tracking cookies, no audience analytics and no ads. The fonts and images come from the site itself. It remembers your language choice only in your own browser.

12. Changes to this policy

If something important changes, we update this page and the date at the top. Changes that significantly affect your data will also be announced in the app.
