How to check DeepL in your own company
- 01Find out which plan each account is on. The vendor's terms differ between DeepL Translator and Write (free version) and DeepL Pro, API Pro and Write Pro. People who signed up with a personal address are on the personal terms, whatever the company bought.
- 02Open the account or administrator settings and look for the data-controls or model-training setting the vendor's page describes. Note what it is set to today and who is able to change it.
- 03Read the vendor's own page, linked under each fact below, and check that the sentence quoted here is still there. Pages change; the date shows when this one was read.
- 04Compare with your contract or order form. Where a data processing agreement or negotiated terms exist, they take precedence over the public pages.
- 05Record the plan, the setting and the date in your AI inventory, so that the answer exists the next time a customer or auditor asks.
What to ask the vendor
Neutral questions for the points the vendor's public pages left open. Ask for the answer in writing.
- 01How long are prompts, files and outputs kept by default, and can an administrator shorten that period?
- 02Is a zero-retention option available on our plan, and what does it exclude (for example abuse monitoring logs)?
- 03How do we request deletion of our data, and within how many days is it completed, including backups?
- 04Can your staff or contractors read our inputs? In which cases, and is that access logged?
- 05Is single sign-on available on our plan, and can sign-in with personal accounts be blocked for our domain?
- 06Is SCIM provisioning available, so that leavers lose access automatically?
- 07Are audit logs available to administrators, and can they be exported to our security tooling?
- 08Is there an administrator console where data controls can be set for every account in our organisation?
- 09Where is our data processed and stored, and can a region be chosen?
- 10Do the statements on your public pages apply to our contract as written, or do negotiated terms override them?
