Frequently asked questions

Do you offer any discounts?

Yes! We offer volume discounts for all our services. The more data you need, the less you pay per datapoint. We also offer discounts for our returning customers as part of our customer advocacy programme.

We provide over 100 languages from around the world. Check out our European languages here as an example, or contact us for more information. Our network of over 110 million native speakers means you’ll have access to even the rarest of languages, allowing you to scale your projects to almost any language.

How are you privacy compliant?

We designed our technology to be compliant with the strictest privacy laws in the world since day one. We understand the importance of keeping up with everchanging privacy regulations across the world and we enable you to do so easily. In projects where personal data needs to be transferred, we sign data processing agreements before starting cooperation in line with the GDPR. We follow a strict eight-step process to ensure privacy compliance.

Find our more detailed information in our Cyber Security Policies and our Cyber Security Framework.

How do you ensure data security and transfer data?

We protect your data at every stage. We store the data on ISO-27001-certified cloud servers which are all located within the EU. Once a dataset is ready, the easiest way to receive it is on your cloud provider's storage solution, such as a bucket, or to download it with password-protected download links that we provide to you.

How can you accommodate such quick delivery times?

Our technology provides access to over 110 million native speakers around the world. With no training required, our network is ready to get to work on your tasks as soon as your project specifications are ready. They also verify each other’s work, making our quality control efficient. This is how you’re able to benefit from increases in turn-around of an average of 50% compared to traditional methods.
