守钓

StashMap ShouDiao
A fishing spot management tool for anglers. Your spots stay on your phone, never uploaded to the cloud.

Core Features

- Map Pinning: Mark fishing spots on a map, recording location, target species, time, notes, photos, and videos.
- Hand-drawn Bottom Structure Layers: Sketch underwater structures directly on the map with 22 semantic structure types (deep water, shallow flats, weeds, reefs, fish runs, spawning grounds, etc.).
- Encrypted Sharing: Generate encrypted files; share the decryption key separately via a different message to trusted anglers. The recipient must enter the code to open it.
- Encrypted Backup: One-click export of all data into an encrypted file, ensuring no loss of data when switching phones.
- Fishing Log: Review every trip in chronological order with photos, videos, catches, weather conditions, and water temperature.

22 Underwater Structure Layers

View your waters like nautical charts. Hue distinguishes families (depth / vegetation / obstacles / hydrology / structures), patterns distinguish specific structures, and strokes indicate boundary characteristics (clear / dynamic / gradient / regular / scattered).

Layers drawn by anglers carry complete semantics. When shared, it’s not just an image, but “underwater intelligence.”

Encrypted Sharing · Security by Default

Want to share with trusted anglers? Generate a .fspot encrypted file (AES-256-GCM). Send the key and the file via two separate messages.

The server never handles the encrypted file or stores the key. Without the key = cannot open. Screenshots or forwarded copies are useless.

Design Philosophy:
Fishing spots are an angler’s asset, not platform content.
We built this tool because we are anglers ourselves—we don’t want our fishing spots seen by anyone, including the app’s servers.
