This policy explains what data DigiStella processes for the digiseer.app website and the DigiSeer service, why, for how long, and how to exercise your rights.
This website
digiseer.app sets no advertising or tracking cookies. Audience measurement uses Matomo, hosted by DigiStella, configured without cookies and with anonymised IP addresses.
IP addresses are truncated (2 bytes masked) before anything is stored, no cookie is set and your browser’s “Do Not Track” setting is respected. Visit details are deleted after 25 months; only anonymous totals (page views, countries, referrers) are kept. These statistics are only used to improve the website and are not passed on to anyone. The same cookie-free audience measurement applies to the DigiSeer application (app.digiseer.app).
The country, sometimes the region, is derived from the already truncated IP address: never a precise location.
For the address of the page you came from, Matomo keeps only the site and the page, without the end of the address, which could contain personal data.
No account identifier is sent to Matomo, and the addresses of the application’s pages are sent to it without their parameters.
If you opt out of audience measurement with the form below, your browser keeps this choice in a small marker, used for nothing else.
You can also opt out of this audience measurement:
Cookies
The digiseer.app website sets no cookies: there is nothing for you to accept or refuse. The only exception: if you opt out of audience measurement, a small cookie remembers that choice.
The app.digiseer.app application only uses session cookies, which are needed to stay signed in.
They are protected and cannot be accessed by the page’s scripts.
The DigiSeer chat installed on our customers’ websites sets no cookies for their visitors.

Contact and demo requests
When you write to us, through the contact form or by email, we use your name, email address, website if given, chosen subject and message to reply. The message reaches us by email; it is not stored on the website. Legal basis: our legitimate interest in answering you. Retention: 3 years after our last exchange.
Newsletter
If you tick the subscription box, in the contact form, when creating your account or in the app dashboard, we use your email address to send you the DigiSeer newsletter (what’s new and tips, at most once a month), together with the language chosen and the date you subscribed. Legal basis: your consent, which you can withdraw at any time with the unsubscribe link in each newsletter or by unticking the box in the app. Your address is only used for this: it is never sold or passed on. Sent by Brevo (France). Retention: until you unsubscribe.
Customer accounts
For DigiSeer customers we process account, billing and usage data to provide the service and invoice it. Legal basis: the contract. Authentication is provided by Supabase, payments by Stripe and service emails by Brevo.
Retention: for the duration of the contract, then 30 days. Invoices are kept for 10 years, as required by law.
The DigiSeer assistant
Questions typed in the assistant are sent to DigiSeer to produce an answer, and processed in the European Union: hosting in France, Mistral AI’s model through its European endpoint. For this data, DigiStella acts as a processor for the website that uses DigiSeer. DigiSeer sets no cookies for visitors and builds no profiles.
- IP addresses: never stored in clear. They are replaced by an encrypted fingerprint, used to limit the number of questions per day, and deleted after 13 months.
- Questions: email addresses, phone numbers and long numbers are masked before storage. Questions feed the statistics of the website concerned and are deleted no later than 30 days after its contract ends.
- Visitor suggestions: an email address left with a suggestion is deleted after 12 months.
- Answers: each answer from the assistant is stored with its question and the list of website pages read to produce it, so that the website can check what its visitors were told. Answers are deleted after 12 months.
- AI model: Mistral AI does not use this data to train its models and keeps exchanges for 30 days to detect abuse.
- What DigiStella never does with it: this data is never sold, rented or handed over to third parties; it is not used for our search engine ranking, our own content, advertising, or to answer visitors of other websites. No one at DigiStella looks at it, except at the request of the customer website (support) or for the security of the service.
Sub-processors and transfers
Our sub-processors are listed on the Sub-processors page. Customers’ content and visitors’ questions do not leave the European Union. Account data is hosted by Supabase in Frankfurt; as Supabase, Inc. is a US company, any access from the United States is governed by its data processing agreement. Payment data is processed by Stripe Payments Europe, in Ireland, which may transfer it to the United States under the Data Privacy Framework.
Your rights
You can delete your DigiSeer account yourself from the My account page of the app: it is deleted 30 days after your request, with your sites. To access, correct or port your data, or object to its processing, write to us from the Contact page. If you are a visitor of a website that uses DigiSeer, contact that website first: we will help it answer. You may also contact the CNIL (cnil.fr).
