MountainCSV is made by one person. You'll get a reply from the developer, not a ticket bot — usually within two working days.
MountainCSV is sold through the Microsoft Store for £19.99, once. There is nothing to activate and no code to enter: your purchase is tied to your Microsoft account, so there is nothing to keep safe and nothing to lose.
Sign in to the Microsoft Store with the same account and reinstall — you won't be charged again. Your purchase follows the account, not the machine.
Yes. The Store allows installation on your own devices under one account. Please don't share it outside your own use — it's a one-person product sold on trust.
The 7-day trial is the complete app with nothing held back. When it ends, buy it from the Store and carry on — your files, settings and recent-file list are untouched.
Store purchases are refunded by Microsoft — request one from your Microsoft account's order history. If that gives you trouble, email us and we'll help chase it, no argument and no form to fill in. The 7-day trial is there so you can be certain before you pay, but the offer stands regardless.
The quickest route is from inside the app — Help → Send feedback — which attaches your app version and operating system automatically so we can reproduce it. You can also email us directly.
Useful things to include: what you expected, what happened instead, and — if you can share it — a small sample file that reproduces the problem. Never send data you can't share; a handful of dummy rows that show the same fault is far more useful than real records.
No. MountainCSV makes no network calls with your data — no telemetry, no analytics, no account. Bug reports are the one exception, and they only contain what you type plus your version and operating system. Your files are never attached automatically.
Purchases go through the Microsoft Store, which acts as the merchant of record and handles VAT — your invoice is in your Microsoft account's order history. If you're having trouble finding it, email us and we'll point you the right way.
Purchase problems, refunds, bugs, feature ideas — all to the same address.
