Privacy Policy

LoopLab app for iPhone, iPad, and Android

Core Principle

Your account holds only what you practise, and you can delete it anytime.

The app shows the loops and words you saved in LoopLab for Chrome. To do that it needs your LoopLab account: your email address and the data you synced. No ads, no tracking, no data sold or shared for advertising.

No Password

You sign in with a code we email you.

No Tracking

No advertising IDs, no ad networks, no usage analytics in the app.

Only Your Devices

Your synced data is readable only by your signed-in devices.

Delete Anytime

Me → Delete account deletes your email and all synced data at once.

Data In Your LoopLab Account

  • –Email address: to sign you in with a code (no password) and to match your phone with LoopLab for Chrome
  • –Saved loops: times, subtitle text, video title and link, language, favorite
  • –Word Booklet: words, meanings, status (learning / known), the sentences and video moments you saved them from
  • –Library: video titles, links, last position, length, favorite

It comes from LoopLab for Chrome when you turn on Sync there. Changes you make in the app (a word marked known or deleted, a loop starred) are saved to your account and reach the extension too. It is used only to provide these features. On the phone, the app keeps your sign-in in the system keychain / secure storage.

Services The App Uses

Supabase (LoopLab account)

While you are signed in

Stores your account and synced data (above). Only your signed-in devices can read it.

Resend (email delivery)

When you ask for a sign-in code

Your email address, to send you the code.

App Store / Google Play and RevenueCat

Only when you buy or restore LoopLab Pro

Apple or Google handles the payment. RevenueCat (our purchase service) checks the purchase with them and tells our server, linked to your LoopLab account ID. We never see your payment details.

YouTube

When you practise a loop

The video plays in YouTube's embedded player inside the app, as on any website with a YouTube video. Google's privacy policy applies to the player.

Your phone's voices

When you tap 🔊

Words and sentences are read aloud by your phone's own speech voices, on your device.

Your phone's translator

When you choose a meaning language other than English

The meaning is translated on your device (Apple Translation on iPhone and iPad, Google ML Kit on Android). The language pack is downloaded once from Apple or Google; the words you look up are not sent for this.

LoopLab server and Anthropic (Claude)

Only when you press ✨ AI explanation (signed in)

The word, its sentence, and the two language codes, to explain the word in that sentence. Answers are stored without your account so other learners get the same answer faster; your account is used only to count your daily explanations. Anthropic processes the request under its commercial terms and does not train on it.

Offline dictionary (Cloudflare R2)

When you download a dictionary in Me

A normal file download; nothing about you or your words is sent.

Wikimedia (Wiktionary)

When you tap a word for its meaning

The single word (and its base form) to fetch its meaning. No account or video information. Wikimedia's privacy policy applies to that request.

Emails You Send Us (Website)

When you use the Support form or Notify me about Pro on this website, we receive your email address, the product and topic you choose, your message, and any image you attach. They are delivered to us by email through our email provider (Resend).

We use them only to reply to you or, for Pro sign-ups, to tell you when LoopLab Pro is released. We do not sell them or add you to other mailing lists. To have your messages or sign-up deleted, contact us through the Support page.

Deleting your account. In the app: Me → Delete account (or in LoopLab for Chrome: Sync → Delete account). This deletes your email address and every synced loop, word, and video from our servers at once and signs you out. Loops saved in LoopLab for Chrome on your computer stay there. Signing out keeps the account. You can also ask Support to delete it.

Purchases. LoopLab Pro in the app is bought through the App Store or Google Play; RevenueCat verifies the purchase for us. We keep a record of the plan, its status, and its end date, linked to your LoopLab account, so Pro also works in LoopLab for Chrome; never your payment details. Pro bought on the website (LoopLab for Chrome) is handled by Polar. Manage or cancel a store subscription in your App Store or Google Play account.

Children. LoopLab is not directed at children under 13 and does not knowingly collect personal information from them.

Changes. Changes to this policy will be posted on this page with a new date.
