Vantero is an AI-powered chat and productivity platform that provides access to various large language models through a unified interface. The platform is offered as a web application and as a mobile app (iOS/Android). Personal data is processed during use insofar as this is necessary to provide the service, ensure security, and fulfil legal obligations.
In the course of using Vantero, we process the following categories of personal data:
The processing of your personal data is based on the following legal grounds:
The processing of account data, chat content, uploaded documents, and usage data is necessary for the performance of the user agreement (provision of the AI platform). This includes in particular:
Based on our legitimate interests, we process data for the following purposes:
We obtain consent where legally required, in particular for:
Consent may be withdrawn at any time with effect for the future.
Where we are subject to statutory retention obligations (e.g. tax law retention periods for billing data), we process your data on this basis.
Vantero offers the following login methods:
When registering with email and password, your password is stored exclusively as a cryptographic hash. The plaintext password is never stored. You will receive a verification email to confirm your email address.
When using the magic link method, you receive a one-time login link by email that expires after 10 minutes. No password is required or stored.
In the mobile app, a six-digit one-time code can alternatively be requested by email, which expires after 10 minutes.
When logging in via Google, your name, email address, and, where applicable, your profile picture are transmitted to us by Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. The use of Google OAuth is based on your consent (Art. 6(1)(a) GDPR). Google's privacy notice: https://policies.google.com/privacy.
The authentication solution is based on Better Auth, an open-source library that runs entirely on our own infrastructure. No authentication data is transmitted to external third-party services (except to Google when using Google OAuth).
All persistent user data (account data, chat histories, documents, workspace data, assistants) is stored on servers operated by IONOS SE in Frankfurt am Main, Germany. No replication of this data occurs outside of Germany.
Vantero offers a data zone model in which you can choose the geographic region where your AI requests are processed. The data zone is determined by the selected AI model. Only the chat input (prompt) and any attached files are transmitted to the respective AI provider – no account data, email addresses, or other master data.
| Data Zone | Provider | Server Location | Legal Basis for Transfer |
|---|---|---|---|
| Germany | IONOS SE, STACKIT (Schwarz IT KG) | Frankfurt a.M., Heilbronn (DE) | No third-country transfer |
| France | Mistral AI SAS | Paris (FR) | No third-country transfer (EU) |
| Europe | Microsoft (Azure), Amazon Web Services, Google Cloud | EU regions (DE, FR, BE, FI) | No third-country transfer (EU Data Boundary) |
| USA | Perplexity AI, Inc. | USA | EU Standard Contractual Clauses (SCCs) pursuant to Art. 46(2)(c) GDPR; EU-US Data Privacy Framework where applicable |
Processing in the "USA" data zone only occurs if you actively select a model from that zone. Without an active model selection, only models from the "Germany" zone are used.
A transfer of personal data to third countries (countries outside the EU/EEA) only takes place in the following cases:
When selecting an AI model from the "USA" data zone, your chat inputs are transmitted to Perplexity AI, Inc. (registered office: San Francisco, USA). The transfer is safeguarded by the following guarantees:
Only the chat input data (prompt content) is transmitted. Account data, email addresses, or other master data is not shared with Perplexity AI.
When using Google login, a connection is established with Google servers. While Google Ireland Limited is based in the EU, it may transfer data to Google LLC in the USA. The transfer is safeguarded by the adequacy decision for the EU-U.S. Data Privacy Framework and by SCCs.
We engage the following data processors to provide our service, with whom data processing agreements (DPAs) pursuant to Art. 28 GDPR have been concluded:

This applies to all available AI models across all data zones. We have concluded contractual agreements with all AI providers that prohibit the use of transmitted data for training purposes.
Pursuant to Art. 50(4) of Regulation (EU) 2024/1689 ("EU AI Act", in force since 1 August 2024, transparency obligations applicable since 2 August 2025), we inform you of the following:
Vantero is a technical platform providing access to AI models. The AI systems accessible through Vantero are classified as general-purpose AI systems pursuant to Art. 51 et seq. EU AI Act. The providers of these models bear responsibility as AI model providers within the meaning of the regulation. As the deployer, we fulfil the transparency obligations incumbent upon us, inter alia through this privacy policy.
No automated individual decision-making within the meaning of Art. 22 GDPR takes place via Vantero. All AI responses are to be understood as assistance and do not constitute legally binding statements.

Third-party analytics, advertising, and marketing technologies are not currently active.
You can access current information about these technologies at any time via the "Privacy Settings" link or button. We also provide our consent management for future optional categories there.

Emails are sent via an SMTP service. No email marketing or newsletter distribution takes place.
Payment processing for paid plans (Basic, Pro, Team), extra seats, and token packages is handled by Armitage Labs OU (Creem) (“Creem”) as Merchant of Record.

Creem collects and processes the data required for payment processing, invoicing, tax calculation, and fraud prevention (e.g. name, email address, billing address, payment information, business and tax details) as an independent controller. We receive from Creem via webhook or API only the reference data necessary for assignment and contract fulfilment:
Credit card or bank data is never transmitted to us or stored on our servers. Creem’s privacy policy can be found at: https://www.creem.io/privacy.
Legal basis: Art. 6(1)(b) GDPR (performance of contract).

Providing your email address is required to use Vantero (contract conclusion). Without providing an email address, no user account can be created and the service cannot be used.
