About DentroChat
DentroChat is an AI chat service operated by DentroInnovation OÜ in Tallinn, Estonia. The product bundles text chat, image generation, web search, file and voice workflows, memory and workspace tools behind Fast, Thinking and Creative modes.

The company publishes terms, privacy, legal notice and a subprocessor list; no public DPA or security-certification page was found during this refresh.

Questions & Answers
6 questions
Where is my data stored?
DentroChat says account data and chat history are handled on its Hetzner servers in Germany. Encrypted backups are stored at Hetzner in Germany and Scaleway in France. AI requests may pass through the EU or Swiss AI and search providers listed on its subprocessor page, then results are stored on the German application servers.
Which AI and search providers process my prompts?
Chat messages are routed via Cortecs in Austria to Mistral AI, Nebius, Infomaniak, Inceptron, Tensorix or AKI.IO for language-model inference. Image generation is processed by Black Forest Labs in Germany, and web search by Linkup Technologies in France.
Is DentroChat subject to the US CLOUD Act?
The published legal notice identifies DentroInnovation OÜ in Estonia as the operator. The privacy and subprocessor pages say DentroChat does not use US-based subprocessors or US cloud services, and no US parent or subsidiary is disclosed on the public site. Based on those public sources, this profile marks CLOUD Act exposure as none.
What's included in the paid plan?
The public pricing section lists one unlimited plan with Fast, Thinking and Creative modes, memory across conversations, web search, image generation and file uploads. Users start with 15 free messages after signup; after that, the site advertises a 7-day €1 trial, then €12 per month or €97 per year.
Does DentroChat train AI models on my conversations?
DentroChat's privacy policy says it does not use chat conversations to train AI models. It also says AI providers process prompts solely to generate responses and do not retain customer data for training.
Does DentroChat publish a DPA or security certification page?
DentroChat publishes public terms, a privacy policy, a legal notice and a subprocessor list. During the 2026-06-24 refresh, /dpa, /data-processing-agreement, /security and /trust returned 404 responses, so no public DPA, security page or certification page was recorded.
