Terms of use

These terms cover your use of Lookupper for Windows, free or with Pro.

Parties

The licensor is Aleksei Vekhov, creator@lookupper.com, who owns the copyright in Lookupper. The licensee is you, the person using the app.

Accepting these terms

By installing or running Lookupper for Windows, whether from lookupper.com or the Microsoft Store, you accept these terms in full.

Lookupper for Mac is available only in the App Store and is licensed under Apple’s standard license agreement, not these terms.

What you get

You get a non-exclusive, worldwide license to install Lookupper for Windows on computers you use, run it and use its features as intended. The license is free. Pro is paid, at the price on the purchase page, under the terms of sale.

Without Pro, some features are limited and some aren’t available; the Pro purchase page shows which. Pro removes these limits for the period you pay for, and a lifetime key removes them for as long as these terms last. A Pro key can be active on several computers at once; the purchase page shows how many. You can unbind all computers from a key with the Unbind all button in My keys and activate it again as often as you like.

Cloud features and AI answers

Cloud features are cloud dictionaries, cloud translation and pronunciation. They run over the internet on Lookupper’s servers. The licensor aims to keep the servers available at least 99% of the time but can’t guarantee it: outages, maintenance or connection problems can make cloud features temporarily unavailable.

Cloud features and offline translation use AI to generate their answers, which can be inaccurate or incomplete. The models and services behind these features may change.

Abuse of cloud features

The license lets you send cloud requests only from Lookupper, while you’re using it. Abusing cloud features isn’t allowed. That means sending requests with scripts, bots or macros, sending them straight to the server instead of through the app, or sending more than a person could read.

If you abuse cloud features, the licensor may limit them on the computer the requests came from or block your Pro key without a refund. The licensor emails you about a blocked key at the address used to buy it and may refuse that buyer new Pro keys.

Third-party components

Lookupper includes code, models and dictionaries made by others, which are covered by their owners’ licenses. You can find the list and the license texts in the app under Settings → Lookupper → Third-party notices.

You may not remove or hide copyright and license notices in Lookupper. You may use third-party code from Lookupper outside the app only if its license allows it. These terms give you no more rights to Microsoft’s code than to the rest of Lookupper and don’t limit the rights of Microsoft and its suppliers under their licenses.

Changes to the app and these terms

The licensor may change Lookupper’s features: to keep it working with new versions of Windows and with AI models and services, to keep cloud costs under control, or to fix and improve it. Old versions may stop working after Windows updates or major server changes, and then you’ll need to update Lookupper. Updates are free.

The licensor may publish a new version of these terms on this page, with its date. It applies to you from the first time you launch Lookupper after it’s published. If you don’t agree with it, you can end these terms as described below.

Ending these terms

These terms have no end date. To end them, email creator@lookupper.com saying that you’re ending them and asking for your data to be deleted. They end on the day the licensor receives your email. Uninstalling Lookupper doesn’t end them or delete your data. If you use Lookupper again later, these terms apply again.

Once the terms end, your data is deleted within the periods in the privacy policy. Refunds for Pro follow the terms of sale.

Disputes

If something goes wrong, write to creator@lookupper.com. The licensor believes any problem can be solved and will try to solve it. You can go to court at any time without waiting for a reply, including in the country where you live.

Nothing in these terms limits your rights as a consumer under the law of that country. If any part of these terms turns out to be invalid, the rest still applies.
