How do I restore my Pro purchase on a new browser or machine?

Go to tidemill.io/pro and paste the license key from your purchase receipt email into "Already bought Pro?". There is no account to sign into — the key itself is the receipt, and pasting it unlocks Pro on that browser immediately.

Where is my data stored?

All data is stored in this browser's local storage, encrypted, and nowhere else. There are no servers, no cloud sync, and no account. Clearing your browser's site data or switching machines does not carry it over — use Pro's encrypted backup (on the /pro page) to move data between browsers.

I cleared my browser data. Can I get my tool data back?

Only from a Tidemill Pro encrypted backup file made beforehand (Download encrypted backup, on /pro). There is no server-side copy to restore from. Your Pro license itself is not affected — paste your key on /pro to restore Pro even if the underlying tool data is gone.

A tool isn't loading correctly. What should I try?

First, hard-refresh the page (Ctrl/Cmd+Shift+R) and try a different browser to rule out an extension or cache issue. If it persists, email us with the tool name, your browser and version, and what you were doing when it happened.

Can I move my data to another browser or computer?

Yes — on the /pro page, Pro includes an encrypted backup and restore: download an encrypted file from the old browser, then restore it in the new one with the same passphrase. This is the only way, since nothing is stored on our servers.

I was charged but Pro isn't showing as unlocked.

Check your email for the receipt containing your license key, then paste it into "Already bought Pro?" on tidemill.io/pro. If you can't find the key or it won't verify, email us from the address you paid with and we'll reissue it.

Do the tools work offline?

Yes — every Tidemill tool runs entirely in your browser and keeps working without a network connection once the page has loaded. Some tools (WiFi Pulse, Zero Remote) talk to devices on your local network but never require internet access.
