## What is Picin?

Thousands of photos lie silent in your library, rarely revisited. PicIn is not another photo editor—it helps you rediscover the moments worth keeping, turning them into a living time portfolio you can view, share, and live with every day.

Roam through time. Reconnect with every frame.
1. Infinite 3D Roam Canvas · Auto-Cruise Pinch to zoom, drag to glide—thousands of photos drift effortlessly into view in 3D space. Double-tap the blank canvas to toggle Auto Roam, letting your album unfold like a moving scene.
2. 4 Dimensions · 19 Curated Roam Lenses See time through a different lens:  Time — On This Day / Time Rewind (dual-slider range) / Seasonal Moments / Season Slice / Year Slice / Vintage Years  Footprint — Nearby Stroll / City Drift / Faraway Escape  Light — Golden Hour / Midnight Atelier / Morning Glow  Curated — Pure Live Photos / Panoramas Wide / Favorites Highlight  Pro Exclusive — Custom Multi-Dimensional Filter: Freely combine time, place, season, and media traits to pinpoint exactly the memory you want.
3. Smart Random Discovery Every day, a themed recollection is shaken up from time, light, and footprint combinations—Old Town Tales, Late Night Live Frames, Right Now Across Time… every shuffle brings something new.
4. Evening Memory Letters + Sunday Weekly Slices A gentle, photo-rich push notification lands each night. Every Sunday at 20:30, a Weekly Time Slice arrives, wrapping up the past 7 days of quiet, cherished moments.
5. Golden Narrative Seal Easter Eggs Special photos auto-earn a glowing gold badge, paired with warm storytelling captions: "You pressed this shutter on the same day, 3 years ago." "Taken a thousand miles away — that distant corner no map ever names."
6. Lucky Pick · One-Tap Inspirations Auto-picks 5–6 photos from the canvas, randomly pairs a high-end template with an art texture, and instantly generates a wallpaper or collage. A fresh surprise every time.
7. High-End Atelier Studio 5 templates (Polaroid / Chrono Slices / Wet Emulsion / Hanging Film / 3D Accordion) × 10 art backdrops (Oak, Bauhaus, Obsidian, Sunset, Concrete, Pine, Noir, Vintage, Lavender, Indigo). Pixel-perfect presets for all iPhone & iPad models, desktop wallpapers, and multiple aspect ratios — up to true 4000px lossless export.
8. Satisfying Curation Mark favorites to sync with the system library. Removing clutter dissolves the frame into an elegant particle grid. Tidying up never felt so good.

【Purely Local & Privacy First】
Your memories belong 100% to you. PicIn runs entirely on-device. All photo reading, filtering, reverse geocoding, and HD rendering are processed locally. No cloud servers, no forced logins—your privacy is completely protected.
