The deal, in plain language

Ostler Desktop is made and sold by Greulich Labs LLC. “We” and “us” below mean Greulich Labs LLC; “you” means the hotel or person buying the license. Reach us at support@getostler.com.

One purchase ($499) buys a perpetual license to run Ostler Desktop for one hotel property on one computer at a time. Moving to a new computer is fine — restore a backup and activate there; retire the old install. The license covers every update we release for Ostler Desktop, delivered automatically.

If you buy and something genuinely doesn’t work for your hotel, write to support@getostler.com within 30 days of purchase and we’ll refund it. A refunded key is deactivated.

Your data lives on your machine, so backups matter: the app automates them and nags you gently, but keeping at least one backup somewhere other than the front-desk computer is your job. Your email and OTA accounts are yours — their fees and terms are between you and them.

We build Ostler carefully — money is integer-arithmetic, every change is journaled, the database is snapshotted before updates — but no software is faultless. Ostler is provided as-is; to the extent the law allows, our liability is capped at what you paid for the license. Nothing in these terms removes protections your local law gives you.

Activation, updates, and opt-in crash reporting are the only things that ever touch Ostler’s infrastructure — and the app functions fully if all of it disappears. That isn’t just architecture; treat it as a term: your ability to run the software you bought never depends on us staying in business.
