Privacy Policy

This policy explains what VibeCurrent LLC (“we”, “us”) collects when you use the Vocalibrate iPhone app and this website (together, the “Services”), why, who it is shared with, and how to delete it.

In short: you can study without an account, and then your progress stays on your phone. Sentences you write or say are sent to our server and to OpenAI to be checked. With an account, your progress is stored on our servers so it can be restored. We don’t show ads, sell your data or track you across other apps and websites.

1. Who we are

• Company: VibeCurrent LLC, a Florida limited liability company
• Address: 7901 4th St N STE 300, St. Petersburg, FL 33702, USA
• Email: support@vibecurrentlabs.com

2. Studying without an account

Without an account, your progress, settings and answers are stored only on your phone. We don’t receive them, and deleting the app deletes them.

To check a sentence you write or say, the app creates an anonymous ID with Firebase Authentication, so our server can limit how many checks each person makes. That ID is not linked to your name, email or Apple ID.

3. What we collect

Your account

An account is optional. If you create one, we collect:

• your email address, and a password that Firebase Authentication stores in hashed form, so we never see it; or
• if you use Sign in with Apple, an identifier from Apple, the email address Apple shares (which may be a private relay address) and your name, if you choose to share it.

Your study data

With an account, the app uploads your study data so it can be restored on a new phone or after a reinstall. When you create an account, the progress already on your phone is uploaded too. Study data is:

• the decks you study, how many new words a day you chose and your reminder time;
• each word’s progress and the date of its next review;
• a record of each exercise: the word, the answer you typed or said, how it was rated, how long you took, any hint you used and the time;
• for decks in a second language, the corrected version of your own sentence and its translation.

We use the exercise record to run your schedule and to improve how Vocalibrate times reviews, by studying how well words are remembered.

Sentences you write or say

Some exercises ask you to use a word in a sentence. To check it, the app sends the sentence, with the word it is about, to our server, which sends it to OpenAI. The reply says whether you used the word with its meaning, with a short tip. For decks in a second language, a sentence you got right may also be sent to be corrected and translated, so you can review it later. Our server doesn’t keep the sentence after the check, except as part of your study data if you have an account.

Please don’t put personal details, about you or anyone else, in your sentences.

Your voice

The app uses the microphone only after you tap its microphone button to say a sentence. Apple’s speech recognition turns your speech into text, on your phone where it can; otherwise Apple may process the audio under its own privacy policy. Only the text is used. We never receive, keep or upload recordings of your voice.

Technical information

Our server keeps short operational logs, such as “a sentence was checked”, with your account or anonymous ID, the deck, the word, the result and how long it took. The logs never contain your sentences, answers or email address. Our hosting providers may record your IP address, as any web server does, to deliver the Services and keep them secure.

What we don’t collect

• your location, contacts, photos or health data;
• recordings of your voice;
• an advertising identifier. The app has no ads, no advertising SDKs and no analytics SDK.

4. Reminders

If you allow notifications, the app schedules its reminders on your phone. Your reminder time is stored with your study data if you have an account. We don’t send push notifications from a server.

5. How we use information

• to run the Services: your sessions, your schedule, checking your sentences, and syncing and restoring your progress;
• to manage your account and answer you when you contact us;
• to improve the Services, such as review timing and how sentences are checked;
• to keep the Services secure and limit abuse;
• to meet legal obligations.

We don’t sell or rent personal information, share it for advertising, or use it to track you across other companies’ apps and websites.

6. Who we share it with

We share information only with the providers that run parts of the Services for us, under their own privacy terms:

• Google Firebase (Authentication and Cloud Firestore): sign-in, and storing account study data.
• Fly.io: hosting our server.
• OpenAI: checking, correcting and translating the sentences you write or say, and the answers to the website’s placement test, sent with the words they are about and never with your name or email. OpenAI handles them under its API data policies, under which data sent through its API is not used to train its models by default.
• Apple: Sign in with Apple, speech recognition and the App Store.
• Our website host: serving this website.

We may also disclose information when the law requires it, to protect the rights and safety of our users or of VibeCurrent LLC, or to a successor in a merger, acquisition or sale of assets, which would remain bound by this policy.

7. This website

The website uses no cookies, no analytics and no advertising. Our host keeps standard server logs, such as IP address and pages requested, to deliver and protect the site.

The placement test (Calibrate) sends the meanings you type to our server, which sends them to OpenAI to be checked, with the words they are about. We don’t keep your answers. We keep only each word’s score, with no name, account or IP address, to improve the test. Our host checks that the test’s requests come from a browser rather than a script, and your IP address is used only to limit how many rounds can be checked.

8. How long we keep it, and deleting it

• Account data is kept until you delete your account. In the app, go to Settings, then Delete account. That deletes your sign-in, settings, progress and exercise records from our servers straight away. If you used Sign in with Apple, the app also asks Apple to revoke Vocalibrate’s access.
• Data on your phone is deleted when you delete your account, sign out or delete the app.
• Server logs are kept for a limited time, then deleted.

You can also ask us to delete your data by writing to support@vibecurrentlabs.com from the email address on your account.

9. Security

Data travels between the app and our servers encrypted, and the app never reads or writes the database directly: only our server does. No method of storage or transmission is completely secure, so we can’t guarantee absolute security.

10. Your rights

Depending on where you live, including in the European Union, the United Kingdom and California, you may have the right to:

• access the personal information we hold about you, and get a copy of it;
• correct it;
• delete it;
• object to or restrict how we use it;
• withdraw consent you have given.

To use any of these rights, write to support@vibecurrentlabs.com. We will answer within the time the law allows and won’t treat you differently for asking. You may also complain to your local data protection authority.

Where the GDPR applies, we use your information to provide the Services you ask for (performance of a contract), for our legitimate interests in improving and securing them, and to meet legal obligations.

11. Where your data is processed

We are based in the United States, and our providers may process your information in the United States and other countries. Where the law requires it, we rely on safeguards such as the European Commission’s standard contractual clauses.

12. Children

Vocalibrate is for people aged 13 and over, and anyone under 18 needs a parent’s or guardian’s permission. We don’t knowingly collect personal information from children under 13. If you believe a child under 13 has given us personal information, write to support@vibecurrentlabs.com and we will delete it.

13. Changes to this policy

If we change this policy, we will post the new version here with a new effective date. If a change is significant, we will also tell you in the app or by email before it takes effect.

14. Contact us

Questions about this policy or your data: support@vibecurrentlabs.com, or VibeCurrent LLC, 7901 4th St N STE 300, St. Petersburg, FL 33702, USA. Our Terms of Service also apply to your use of the Services.
