Keep your Mac’s paths.
Free space with your external disk.
DataDance · 外盘智管 — 路径不丢的外盘空间管理
DataDance relocates Safe-tier data to your external SSD and leaves symlinks at the original paths — so apps and workflows keep working.
How it works
Three clear steps. You stay in control of every move.
Choose your external volume
Pick the SSD once. DataDance remembers it by volume UUID and watches free space on your internal drive.
Review Safe-tier candidates
Old downloads, Xcode DerivedData / DeviceSupport, caches — you decide what moves. Dry-run first, always.
Relocate with paths intact
Data is copied, verified, then replaced with a symlink or stub portal. Original paths keep working. One-click restore when you need it back.

What we never do

-
No silent deletesWe copy, verify, then link — not wipe without a trail.

No password exfiltrationFull Disk Access (optional) is for scanning locations you choose — not reading Mail or Messages.

Pricing
Mac App Store in-app purchase is the primary path. A direct $49 one-time checkout (Gumroad, DataDance) is the backup once payout clears and the product is published — draft is not linked here until live.

FAQ
Short answers to common questions.
Is this a junk cleaner?
No. DataDance is a path-preserving storage relocation tool. It moves data you choose to an external volume and leaves links at the original paths. It is not an optimizer, antivirus, or “speed up your Mac” utility.
What happens if I unplug the external disk?
Automatic relocation pauses. Already-moved items that need the volume will prompt you to reconnect — they should not crash the app that opens them.
Do I need Full Disk Access?
Only if you want scans of protected locations. You can use DataDance with narrower access; grant FDA only when you are comfortable.
What will DataDance never do?
It is not a junk cleaner or “speed up your Mac” tool. It does not silently delete your files. It does not relocate mail or chat libraries. It does not take over your whole iCloud Drive. Relocations are path-preserving and reversible.
How do I buy DataDance?
Mac App Store in-app purchase is the primary paid path. A direct $49 one-time Gumroad checkout is the backup once published. Neither App Store IAP nor Gumroad is live yet — we will not publish fake payment links. Direct Developer ID download is available below.
Will it be on the Mac App Store?
Yes — we are submitting / connecting DataDance (外盘智管) to the Mac App Store. App Store IAP is the main monetization plan. Availability will be announced when approved; until then, treat App Store CTAs as “coming soon.”
