## What is LocalStamp?

LocalStamp is a lightweight tool dedicated to local batch watermarking. It is designed for creators and everyday users who want to protect multiple photos quickly before sharing them to social networks or portfolios.

All processing happens directly on your device. Photos are not uploaded to any server, and the app does not read or collect your photo library contents beyond what is needed to apply watermarks. There are no ads or promotional pop-ups, keeping the experience clean and focused.

### Key Features

- Batch watermarking: Select multiple photos at once and apply a unified watermark to save time
- Text watermark: Customize text content, font (including common Chinese fonts), size, color and opacity
- Image watermark: Use a logo or PNG image as a watermark, ideal for protecting creative work
- Layout and style: Adjust watermark position, margins, repetition density and alignment so marks remain clear without covering the main subject
- Local processing: Watermark generation runs entirely on-device, without relying on remote servers
- No ads: No banner ads, no full-screen ads and no disruptive promotions

### Purchase and Usage

- Try the full set of features for a limited time before deciding to unlock
- One-time purchase unlocks all watermark capabilities permanently, with no subscription and no auto-renewal

Actual pricing is determined by the App Store in your region.

### Privacy and Network Usage

- Photos and watermark content stay on your device; the app does not upload your images
- Network access is used only to communicate with Apple servers when validating purchase status
- No third-party analytics or advertising SDKs are integrated, and no usage tracking is performed
