Data used in our studies

Your public videos and our market studies

Studio PIANA produces market studies on Instagram, and studies of how media cover the news, on Instagram, TikTok and YouTube. To understand which videos work in a field (wellness, food, crafts…), we look at the public posts of many professional accounts in that field. If you are reading this page, your account may have been part of one of these studies. You can object at any time, without giving a reason.

Who we are. GUALDONI PARIS WIEN SAS, trading as Studio PIANA, SIREN 983 001 298, France. Contact: theo@studiopiana.fr.

What data.

• the account name, its number of followers and posts;
• for each video studied: its date, caption, views, likes and number of comments;
• for some studies, the text of public comments, made anonymous as soon as it is collected: we keep neither the name, the account nor the picture of their author, and we remove names mentioned in the text;
• a temporary copy of the video, analysed by an artificial intelligence tool to describe its format, topic, hook and what is said.

We do not collect private accounts, follower lists, messages, or the identity of people who comment.

Where it comes from. Public posts only: through the official interfaces of Meta (Instagram) and YouTube when they provide them, otherwise through a collection provider (Apify) or a copy of the public page, without any account or login on our side.

Why. To produce market studies: compare the videos of a field and draw trends from them (formats, topics, lengths). Our clients receive overall results. A video may be quoted as an example, with the account name and a link to the original post. For news studies: measure the place of each topic in media posts and how the public receives them. We do not sell your data, we do not contact you for marketing, and we make no decision about you.

Legal basis. Our legitimate interest in analysing the market for public professional content (Article 6(1)(f) GDPR), balanced against your rights, including your right to object.

How long.

• video copies: deleted 30 days after their analysis;
• comment texts: deleted 30 days after their analysis;
• analysis results and public figures: 24 months after the end of the study, then deleted;
• if you object: only your account name is kept, on an exclusion list, so that you are never studied again.

Who has access. Studio PIANA and its technical providers: hosting and database (Vercel, Supabase), video analysis (Google), report writing (Anthropic), Instagram interface (Meta), collection of public pages (Apify). Some are based in the United States; transfers are covered by the safeguards provided for by the GDPR: the European Commission's standard contractual clauses and, where applicable, the EU–US Data Privacy Framework.

Your rights. You can request access to your data, its correction, its erasure, the restriction of its use, and object to its processing. You can also lodge a complaint with the French data protection authority, the CNIL (cnil.fr).

How to object. Email theo@studiopiana.fr with the subject “Objection” and your Instagram, TikTok or YouTube account name (or use the form below). Within one month at most, we delete your account's data, add it to our exclusion list and confirm it to you in writing.
