Where Your Files Live, and Who Can Read Them
A folder lives in one of two places. Who opens it is always your pick.
On Folder· 5 GB free
Your Mac
iPhonecoming soon
over HTTPS
Folder
Cloudflare storage in the EU, in our account.
Delete Account on the web deletes your account and every file you keep on Folder.
In Your Cloudflare· Cloudflare's bill, usually $0
Your Mac

Your Cloudflare R2
Your account, your bill: about $0.015 a GB a month after 10 GB free.
Keys are checked inside your account, so the folder works even if folder.dev is down. Uninstall removes every trace.
Who Can Get In
Sign in with Apple
No password to make up or forget. The same sign-in on the Mac and the web, and in the iPhone app when it comes.
A Key Inside Each Device
Each Mac signs its requests with its own key, kept in its Secure Enclave, so a token copied off it opens nothing in your Cloudflare.
Remove one in Settings and it is out of every folder.
Every Change Kept
Every overwrite and every delete is kept, with who made it. Put any version back from Finder or the web.
Share Links
One choice per file. Only a link nothing else protects carries a random id, so it can't be guessed. It ends on a date you pick, or never; Revoke turns it off.
| Who can open it | Its link |
|---|---|
| Only me | no link |
| Anyone with the link | /q3-report-x8k2 |
| Anyone with the password | /q3-report |
| Anyone | /q3-report |
Share links work for a folder in your Cloudflare. A folder on Folder opens only for you.
ChatGPT and Claude
Only on the folders you tick. They never delete or move a file, and each change is a version you can put back.
Disconnect in Settings › Connected Apps.
Not End-to-End Encrypted, and Why
Files are encrypted on the way and at rest, but not end to end: on Folder they sit in our Cloudflare account, where we could open them, and in your Cloudflare they sit in your account, not ours.
Locking files to your devices would switch off ChatGPT and Claude and change how share links and the web work, and losing every device would lose the files, so it is designed, recovery key first, and not in 1.0.
