Please read this policy carefully and ensure that you understand it.

3. What Does This Policy Cover?

This Privacy Policy applies only to your use of our website. Our website may contain links to other websites. Please note that we have no control over how your data is collected, stored, or used by other websites and we advise you to check the privacy policies of any such websites before providing any data to them.

4. What Is Personal Data?

Personal Data is defined by the General Data Protection Regulation (EU Regulation 2016/679) (the “GDPR”) and the Data Protection Act 2018 (collectively, “the Data Protection Legislation”) as ‘any information relating to an identifiable person who can be directly or indirectly identified in particular by reference to an identifier’.

Personal Data is, in simpler terms, any information about you that enables you to be identified. Personal data covers obvious information such as your name and contact details, but it also covers less obvious information such as identification numbers, electronic location data, and other online identifiers.

5. What Are My Rights?

Under the Data Protection Legislation, you have the following rights, which we will always work to uphold:

  1. The right to be informed about our collection and use of your Personal Data. This Privacy Policy should tell you everything you need to know, but you can always contact us to find out more or to ask any questions using the details in paragraph 14.
  2. The right to access the Personal Data we hold about you. Paragraph 13 will tell you how to do this.
  3. The right to have your personal data rectified if any of your personal data held by us is inaccurate or incomplete. Please contact us using the details in paragraph 14 to find out more.
  4. The right to be forgotten, i.e. the right to ask us to delete or otherwise dispose of any of your Personal Data that we hold. Please contact us using the details in paragraph 14 to find out more.
  5. The right to restrict (i.e. prevent) the processing of your Personal Data.
  6. The right to object to us using your Personal Data for a particular purpose or purposes.
  7. The right to withdraw consent. This means that, if we are relying on your consent as the legal basis for using your Personal Data, you are free to withdraw that consent at any time.
  8. The right to data portability. This means that, if you have provided Personal Data to us directly, we are using it with your consent or for the performance of a contract, and that data is processed using automated means, you can ask us for a copy of that Personal Data to re-use with another service or business in many cases.
  9. Rights relating to automated decision-making and profiling. We do not use your personal data in this way.

For more information about our use of your Personal Data or exercising your rights as outlined above, please contact us using the details provided in paragraph 14.

It is important that your Personal Data is kept accurate and up-to-date. If any of the Personal Data we hold about you changes, please keep us informed as long as we have that data.

Further information about your rights can also be obtained from the Information Commissioner’s Office (“ICO”).

If you have any cause for complaint about our use of your Personal Data, you have the right to lodge a complaint with the ICO. We would welcome the opportunity to resolve your concerns ourselves, however, so please contact us in the first instance, using the contact details in paragraph 14.

6. What Data Do You Collect and How?

We only collect Personal Data directly from you via our website contact form. We do not sell your contact information.

As a data controller, we only collect Personal Data about you which does not include any special types of information. This does, however, include your name or email address, company or personal address, and contact telephone number if you provide one which you exchange with us in the course of setting up a business relationship with us.

The translation function on our website runs on your device. The text you enter is processed entirely on your device and never leaves it. For the avoidance of doubt, we do not transmit, process, retain, or store the text you enter or its translation.

When you select a language pair, your browser downloads a translation model from our site. We may count how times each model is downloaded.

Your device automatically transmits certain data for technical reasons when you access our website. We do not normally log access to our website except to count how often each translation model is downloaded. However, if the site malfunctions or consumes large amounts of bandwidth, we may temporarily log IP address, user agent (including browser and operating system version), date and time, HTTP referer, and names of files accessed to diagnose and rectify the problem.

Our translation models are trained on publicly available text, including crawls from public web sites. These data sources may contain your Personal Data.

7. How Do You Use My Personal Data?

We need to know this basic Personal Data in order to communicate with you in order to provide you with service information and support services.

We do not use any of the text you enter for translation and do not have access to it. We may count how often languages are selected on our website to inform which languages to prioritize and improve the product.

We may also use Personal Data contained in server access logs to manage bandwidth consumption and diagnose errors.

We will not collect any Personal Data from you that we do not need and third parties will not have access to your Personal Data unless the law allows them to do so. If you pay us, your contact information will be shared with our accounting and finance providers enumerated later in this document.

We process Personal Data in the UK and, for the purposes of IT hosting and maintenance, this information is located on servers within the UK.

We use text crawled from public websites to mine for translations. These translations are used to train translation models.

8. How Long Will You Keep My Personal Data?

We will store your Personal Data only for the duration of statutory retention periods, insofar as these prescribe the retention for the respective types of data.

9. How and Where Do You Store or Transfer My Personal Data?

We will mainly store your Personal Data within the UK or European Economic Area (the “EEA”). The EEA consists of all EU member states, plus Norway, Iceland, and Liechtenstein. This means that your personal data will be fully protected under the Data Protection Legislation, GDPR, and/or to equivalent standards by law.

Our employees may work remotely, particularly from from Canada or the United States, and remain bound by agreements covering the privacy of our users.

11. Do You Share My Personal Data?

We will not share any of your Personal Data with any third parties for any purposes, subject to the following exceptions.

If we sell, transfer, or merge parts of our business or assets, your Personal Data may be transferred to a third party. Any new owner of our business may continue to use your Personal Data in the same way(s) that we have used it, as specified in this Privacy Policy.

In some limited circumstances, we may be legally required to share certain Personal Data, which might include yours, if we are involved in legal proceedings or complying with legal obligations, a court order, or the instructions of a government authority.

If any Personal Data is transferred outside of the EEA, we will take suitable steps in order to ensure that your Personal Data is treated just as safely and securely as it would be within the UK and under the Data Protection Legislation.

Our e-mail is hosted by Easyspace Ltd and our website is hosted by OVHCloud. The website also accesses static data hosted by Amazon Web Services. If you agree to pay us, your contact information will be shared with our accounting providers Arcata Ltd. and FreeAgent Central Ltd. Our bank Tide will also know transaction information.

We may publicly post or sell collections of translations mined from publicly available websites. If your Personal Data already appeared on public websites, it may be included in these collections.

12. How Can I Control My Personal Data?

In addition to your rights under the Data Protection Legislation, set out in Part 5, when you submit Personal Data via our website, you may be given options to restrict our use of your Personal Data. In particular, we aim to give you strong controls on our use of your data for direct marketing purposes (including the ability to opt-out of receiving emails from us, which you may do by unsubscribing using the links provided in our emails, writing to us, OR at the point of providing your details.

Regarding data crawled from the web, you may write to us with URLs or strings that relate to you. We will exclude them from the next release of the data and models. If you allow us to retain the list you provide, we will use it for the purpose of excluding it from future releases as well.

13. Can I Withhold Information?

You may access certain areas of our website without providing any Personal Data besides data sent automatically by your browser. However, to use all features and functions available on our website you may be required to submit or allow for the collection of certain data.

We do not use cookies, so there is no ability to restrict cookies.

14. How Can I Access My Personal Data?

If you want to know what Personal Data we hold about you, you can ask us for details of that Personal Data and for a copy of it (where any such Personal Data is held). This is known as a “subject access request”.

All subject access requests should be made in writing and sent to the email address shown in paragraph 14. There is not normally any charge for a subject access request. If your request is ‘manifestly unfounded or excessive’ (for example, if you make repetitive requests) a fee may be charged to cover our administrative costs in responding.

We will respond to your subject access request within 21 days and, in any case, not more than one month of receiving it. Normally, we aim to provide a complete response, including a copy of your personal data within that time. In some cases, however, particularly if your request is more complex, more time may be required up to a maximum of three months from the date we receive your request.

If we have publicly posted translations mined from the web, it can be viewed at paracrawl.eu.
