# Terms of Service

## Who provides the service

Adinspire sp. z o.o. provides the service. Company details: ul. Grzybowska 87, 00-844 Warszawa, Poland. District Court for the Capital City of Warsaw in Warsaw, XIII Commercial Division of the National Court Register, KRS 0000476999. NIP 5272702144. Share capital: PLN 5,000. Write to mch@adinspire.com.

## What the service is

Knock, knock, AI! is a PHP app that you install on your own server. It is free. It is covered by the Free Use Licence: you may install and use it on your own websites and on the websites of your clients, and you may not sell it, distribute a modified version or publish it under a different name. You can download it from this website: [knock-knock-ai.zip](https://knockknock-ai.app/download/knock-knock-ai.zip). A PRO version is planned, and these terms cover the free version.

Three functions run through an Adinspire service at `api.adinspire.com`: the Access view, the Common Crawl check and the check for updates. The rest of the app works without it.

## Limits

You get 3 Access checks per day per installation. The free version of the Common Crawl check covers 20 addresses. What goes to the service is described in [What the app stores and sends](https://knockknock-ai.app/docs/privacy-and-data/).

## Technical requirements

You need hosting with PHP 8.2 or newer and the extensions json, hash, zlib, session and pcre. You need write permission in the app folder and access to the access log file of the server (the app reads it directly, or cron copies it, or the app fetches it over SFTP or FTP, or you upload log files downloaded from your hosting panel). A cron job in your hosting panel is preferable; without cron you count the data with the button "Recalculate now". The [install guide](https://knockknock-ai.app/install/) has the details.

## Rules of use

Do not use the service to send unlawful content. Use the Access check only for domains you run or look after.

## Warranty and liability

The app and the service come without warranty. To the extent the law allows, neither the author of the app nor Adinspire is liable for damage that results from using them; the Free Use Licence says the same about the app. This does not limit the rights a consumer has under mandatory law.

## Contract and ending it

The contract starts when you begin to use the service and lasts until you stop. You can end it at any time by deleting the app and stopping the checks. Adinspire may change or end the service, including the checks at `api.adinspire.com`, after notice on this website at least 30 days in advance. Adinspire may block the checks for an installation at once if it breaks the rules of use. Without the service the app keeps working, except the three functions listed above.

## Complaints

Send complaints about the service to mch@adinspire.com. We answer within 14 days of receiving it.

## Law

These terms are governed by Polish law. A consumer keeps the protection that the mandatory law of the country where they live gives them. A dispute with a business goes to the court competent for the seat of Adinspire in Warsaw; a dispute with a consumer goes to the court competent under the general rules.
