About Lowkey Fluent

Lowkey Fluent helps parents understand the slang their kids use, a few minutes at a time. It's for understanding, not for talking like a teenager: get it, don't say it.

How it works

  • Pick what a word means, then see where it comes from and who says it.
  • Miss one? It comes back a few posts later.
  • After 10 you'll get a good place to stop.
  • Heard something just now? Tap 🔍 at the top to look it up. If we don't have it yet, send it to us and we'll research it.

The categories

  • This week: 5 brand-new words every Monday, the same 5 for everyone.
  • Words, Acronyms, Emojis, Memes: what kids say and send.
  • Check Yourself: how your texts come across to them.
  • Retry: the ones you missed.
  • Mature, Political: crude or political slang worth recognizing, with a note for parents. Only shown if you open them.

How words are checked

  • Each entry is researched in several sources: dictionaries, slang trackers like Know Your Meme, and news explainers for parents.
  • Every entry is fact-checked before it goes in, and the whole list is re-checked regularly. Words that fall out of use are removed.
  • Slang changes fast and can mean different things in different places. If your kid says we got one wrong, they may well be right.

It's a beta

A starter set of words for now, so you might run out quickly. Lots more are coming.

We count anonymous visits to improve the app. No cookies, no personal info.

Privacy Policy

Effective October 22, 2026

Lowkey Fluent is run by Hopwhale, LLC ("we"). We collect as little as we can. There are no accounts, no ads, and we never sell or share your information.

What stays on your phone

Your progress (the words you've answered, your name and your icon) is saved in your browser on your device. It isn't sent to us. Clearing your browser data, or tapping Start over on the Me tab, deletes it.

What we collect

  • Anonymous answer counts. The first time you answer a word, we count whether it was right or wrong, with nothing about you attached. That's how the app shows "X% of players got this one right".
  • Anonymous usage statistics. We use PostHog, an analytics service based in the US, to count visits and actions in the app (for example, answering a word, finishing This week's 5, or sharing a card), along with the site that sent you, your device and browser type, and your approximate location (country or city). PostHog receives a shortened version of your IP address, with the last part removed, and uses it only to work out your approximate location. No cookies are used, nothing is stored on your device for this, and we don't build a profile of you.
  • Your email, only if you give it to us. If you sign up to hear when we're out of beta, we keep your email address and the date you signed up. We only use it to tell you about the launch and big updates. You can unsubscribe at any time.
  • Words you send us. If a search finds nothing and you send us the word, we keep the word, the date, and the note and email address if you add them. We use them only to research new words and, if you gave your email, to tell you when we add it. Your searches themselves aren't saved, and suggestions are never shown to anyone else.
  • Technical logs. Like every website, our hosting provider (Railway, in the US) briefly keeps standard technical logs, such as IP addresses, to run the service and keep it secure. Our own server uses your IP address only in memory, to prevent abuse, and doesn't store it.

Who we share it with

Only the services that run the app for us: Railway (hosting) and PostHog (usage statistics). We don't sell, rent or share your information with anyone else, and we don't use it for advertising.

Children

Lowkey Fluent is made for parents and other adults. It isn't directed at children under 13, and we don't knowingly collect personal information from them. If you think a child has given us an email address, write to us and we'll delete it.

Your choices

To unsubscribe, delete your email address, or ask what we hold about you, email hello@hopwhale.com. We'll reply within 30 days.

Changes

If we change this policy, we'll update it here with a new effective date. If the change is significant and you've signed up, we'll email you.

Terms of Use

Effective October 21, 2026

These terms apply when you use Lowkey Fluent, which is run by Hopwhale, LLC ("we"). By using the app, you agree to them.

What the app is

Lowkey Fluent is a free educational app that explains the slang of Gen Z and Gen Alpha to parents and other adults. Slang changes fast and means different things in different places. We research and check every entry, but we can't promise every meaning is complete, current or right for every situation. Please don't rely on it for anything important, such as safety, school or legal matters.

Mature and Political content

The Mature and Political categories explain crude, sexual, sexist and political slang so you can recognize it. They're only shown if you choose to open them. Explaining a word doesn't mean we endorse it.

It's a beta

The app is in beta. Features and content may change, stop working or be removed, and saved progress could be lost.

Using the app

You may use the app for your own personal, non-commercial use. Please don't misuse it, for example by trying to break, overload or copy it in bulk, or by interfering with other people's use.

Our content and other sites

The app's text, design and logo belong to Hopwhale, LLC. The slang itself belongs to everyone. Links on the Sources page go to other websites, which we don't control and aren't responsible for.

No warranty

The app is provided "as is", without warranties of any kind. To the extent the law allows, Hopwhale, LLC isn't liable for any loss or damage that comes from using the app or relying on its content.

Changes

We may update these terms. If we do, we'll post the new version here with a new effective date. If you keep using the app after that, you accept the updated terms.

Governing law

These terms are governed by the laws of the State of Washington, USA.
