Support & Troubleshooting

GUIDESUBSCRIPTIONS

Stego processes images on your device. We cannot access your hidden content. This guide covers common issues and Stego Pro billing.

1. Quick Start

Hide text or image

Pick a large cover image (PNG preferred).
Choose algorithm (LSB is default for PNG output).
Enable Social Media Mode only if you plan to share via apps that resize images.
Save the exported PNG without recompressing to JPEG.

Extract

Use the same algorithm that was used to hide data.
If extraction fails, the app shows a friendly reason (e.g., corrupted or no payload).
Re-shared chat images often break LSB payloads—use original files when possible.

2. Common Failure Reasons

Internal diagnostics use reason codes such as:

no_data:no_magic_header — no Stego payload detected
no_data:crc_mismatch — payload was altered
no_data:truncated_payload — file was cut or recompressed
image_too_small — cover image too small for chosen algorithm

3. Improving Reliability

Keep PNG lossless end-to-end.
Avoid Instagram/WeChat/WhatsApp recompression when possible.
Stay within the capacity indicator.
For JPEG covers, try GN-QIM or DCT modes.

4. Stego Pro & Billing

Stego Pro removes in-app ads; steganography features are unchanged.
Purchases are billed through Apple or Google. We do not store your card details.
Manage or cancel: device Settings → Apple ID / Google Play → Subscriptions, or use Manage subscription in Stego Settings.
Restore purchases: Settings → Stego Pro → Restore purchases.
Refunds: request through the App Store or Google Play.

Subscription terms: Terms of Use

5. Privacy & Ads

Your stego images and hidden content are not uploaded to us. The free tier uses Google AdMob; see the Privacy Policy for advertising and RevenueCat subscription disclosures.

Include: device model, OS version, algorithm used, error message (not your secret payload).

We cannot recover destroyed payloads if the image was recompressed or corrupted after embedding.
