How to use Marlek on your iPhone and iPad

Translate

Open Marlek and type in the top box in Spanish: the Marlek code appears below instantly. Tap the swap button to reverse the direction and paste a secret message to read it in Spanish. You can then copy the result.

The system keyboard

To write Marlek inside other apps, turn the keyboard on once: Settings → General → Keyboard → Keyboards → Add New Keyboard… → Marlek. Then, in any app, tap the globe icon 🌐 on the keyboard until you pick "Marlek." No "Full Access" required.

The table

Open the "Table" tab to see the full key sheet: every letter, number, and symbol with its Marlek equivalent. Handy for learning the code or writing it by hand on paper.

Practice

The Practice tab has four games to learn the code without the table: Time Attack (90 seconds), Write the Letter, Decode the Message and Choose the Answer. Your day streak and your rank are saved automatically.

Share cards

In the translator, type a short message (up to 22 characters) and tap Share as card. Choose what to show (secret message, translation or your rank) and the format (story or square).

My Messages

Tap Save in the translator and the message goes to the My Messages tab, where you can give it a title, search it or delete it. If you use iCloud, you see it on all your devices.

Frequently asked questions

What is Marlek?

Marlek is a cipher language: a secret code where every letter, number, or symbol is swapped for another character or emoji following a fixed table. Its creator (Slime@YT) invented it. The app translates from Spanish to Marlek and back.

Do I need internet to use it?

No. All translation happens on your device. Marlek works offline.

Why do emoji look odd if I retype them?

Some Marlek symbols are emoji with invisible marks. Copy them with the copy button instead of retyping them by hand; that keeps them exact so translating back works perfectly.

Do my messages sync between iPhone and iPad?

Yes, if both have iCloud turned on with the same account. Your saved messages and your Practice progress are kept in your own iCloud, which we cannot access. Without iCloud, they stay on each device only. More details in the privacy policy.

Can the keyboard see what I type?

No. The Marlek keyboard works without “Full Access”: it only converts what you type into Marlek. It does not save what you write and has no internet access.

Does Marlek collect my data?

No. Marlek collects no data. No accounts, no ads, no tracking. More details in the privacy policy.

Which devices does it work on?

Marlek is for iPhone and iPad. On iPad it adapts with a sidebar and a comfortable reading width.
