Stego

Stego lets you hide private text or images inside ordinary photos and extract them later on your iPhone or iPad.

Your cover images and hidden payloads are processed on your device—they are not uploaded to Japality Limited.

FREE & STEGO PRO
Stego is free to use with ads. Stego Pro (monthly or yearly subscription) removes banner, interstitial, and app-open ads. Payment is charged to your Apple ID. Subscriptions renew automatically unless canceled at least 24 hours before the end of the period. Manage subscriptions in Settings → Apple ID → Subscriptions, or in Stego → Settings → Stego Pro.

PRIVACY
See our Privacy Policy for how ads (Google AdMob) and subscriptions (RevenueCat) handle data. Steganography operations themselves stay on your device.

IMPORTANT
Stego is for lawful personal use only. You are responsible for complying with applicable laws. Steganography is not encryption—anyone with the original file may detect or lose hidden data if the image is recompressed.
