Privacy Policy
Last updated: September 2026
Nanga, operated by Spark Digital Agency (SAS), is committed to protecting personal data. This policy describes the data collected via the nanga.spark.do website and the conditions of processing.
Data collected
Nanga only collects data voluntarily provided by visitors: name, email address, and company name via contact and demo request forms, as well as information entered in the Creative Benchmark (Spark) access form. No data is collected automatically beyond strictly necessary technical cookies.
Purpose of processing
Collected data is used to respond to contact and demo requests, grant access to the Creative Benchmark, and send communications about Nanga services if the visitor has consented.
Hosting and storage
The site is hosted on Vercel (European infrastructure). Creative Benchmark data is stored on Supabase (EU hosting). No personal data is transferred outside the European Economic Area, except for the data you choose to share with a third-party AI assistant through the connector described in section 8.
Data retention
Data is retained for the duration necessary for the purposes described above, and no longer than 3 years after the last contact.
User rights
Under the GDPR, every user has the right to access, rectify, delete, port, and object to the processing of their personal data. These rights can be exercised by email at the address below.

Cookies
The site uses only technical cookies necessary for operation. No advertising or third-party tracking cookies are used.
AI assistant connector (ChatGPT, Claude)
If you choose to connect your Nanga account to a third-party AI assistant (OpenAI's ChatGPT, Anthropic's Claude) through our connector, the following categories of data may be shared with that assistant, only when you explicitly ask it to from your own assistant account: account and advertising campaign metrics (spend, purchases, purchase value and similar figures, for one company and period you choose), the content of your already saved marketing analyses (findings, recommendations, metrics), your company's Company Brain text (business context, positioning, priorities) and your dashboard names. No data from any company other than the one chosen at connection, no password and no access token is ever shared with the assistant. This sharing relies on your explicit consent, given per capability at connection time, and its recipient is the provider of the assistant you use (OpenAI, LLC or Anthropic, PBC, both established in the United States): it therefore involves a transfer of personal data outside the European Union, This transfer happens at your own request, from your own account with that provider, and is governed by the contract between you and that provider: Nanga never shares this data on its own initiative. Nanga only keeps technical connection records (assistant, company, authorized capabilities, timestamps) and content-free product events (tool called, outcome, duration), never a copy of the text shared; the assistant provider retains the data it receives under its own terms. You choose, per capability, which data categories each connection can access, and you can revoke a connection at any time from the connections page in Nanga or from your assistant's settings; revoking blocks future reads, while data already shared remains with the assistant under its own rules.
