Privacy policy

Euclium Contact app and euclium.com website. Last updated: 18 October 2026. This translation is provided for information only; the French version prevails.

This policy explains which personal data are processed by the Euclium Contact mobile app and by the euclium.com website, for what purpose, how long they are kept and how to exercise your rights.

1. Data controller

The data described in sections 2 and 4 are processed by FSC SASU, a French simplified single-shareholder joint-stock company (société par actions simplifiée unipersonnelle) with share capital of €100, registered with the Brest Trade and Companies Register (RCS) under number 101 895 787, with its registered office at 435 rue Lucie et Raymond Aubrac, 29490 Guipavas, France, trading as “Euclium”.

For any question about your personal data: admin@euclium.com.

2. Data processed by the Euclium Contact app

Euclium Contact is a professional tool, used by the employees and associates of Euclium’s client companies. It is not intended for children.

Your user account

• Data: email address, name, the company you belong to.
• Purpose: to create and secure your access to the app, and to link you to your company.
• Legal basis: performance of the contract between Euclium and your company, and our legitimate interest in securing access to the service.

Your professional profile

• Data: work phone number (optional), role and department within your company. Your name and phone number are visible to your colleagues in the same company, so that they can reach you.
• Purpose: to organise the team’s work.
• Legal basis: performance of the contract between Euclium and your company.

Content you add

• Data: messages exchanged with your colleagues, notes, photos and documents attached to a request. Photos are sent without their location metadata (EXIF).
• Purpose: to follow up on requests.
• Legal basis: performance of the contract. This content belongs to your company (see section 3).

Your location

The app reads your location only when you tap “Ma position” (My location), and only while you are using it. It is used to suggest the matching address, obtained from the French public Géoplateforme service (IGN). The location itself is not stored: only the address you confirm is.

Notifications

If you allow them, the app stores a token specific to your device, to notify you of a new request or message. This token is routed through Expo and Apple (APNs) or Google (FCM). It is detached from your account when you sign out.

Google Calendar (if your company enables it)

If you link your Google account, the app keeps that account’s address and an encrypted access authorisation. It uses them to add your appointments to your calendar, as private events, and to read your busy time slots. You can disconnect at any time from Profil › Agenda (Profile › Calendar).

Crash logs

• Data: technical description of the error, device model, operating system and app version. Neither your name, nor your email address, nor the content of your records. Sent to Sentry, hosted in the European Union.
• Purpose: to detect and fix errors in the app.
• Legal basis: our legitimate interest in providing a reliable app.

The app collects no advertising identifier and displays no advertising. Your data are neither sold nor rented.

3. Data entered for your company

The leads and customer records entered in the app belong to the company that uses Euclium Contact. That company is the controller of this data.

For this data, Euclium acts as a processor within the meaning of Article 28 of the GDPR: we host and process it solely to provide the service, on the company’s instructions, and we do not use it for our own purposes.

If your data appear in these records, for example because you are a customer or prospect of a user company, please address your requests to that company. If you write to us, we will forward your request to it.

4. The euclium.com website

The website sets no cookies and uses no audience measurement tool, no third-party script and no tracker. Its fonts are hosted on the website itself. It has no forms.

Its host, Cloudflare, processes the technical data needed to deliver the pages and keep them secure (IP address, browser type, date and time of the request). Legal basis: our legitimate interest in providing an available and secure website.

5. Hosting and service providers

The data are processed with the help of the following providers, who act as Euclium’s processors:

• Supabase (Supabase, Inc.): the app’s database and authentication, hosted in the European Union, in Paris (France).
• Expo (650 Industries, Inc., United States), EAS service: distribution of app updates and delivery of notifications.
• Sentry (Functional Software, Inc.), data hosted in the European Union: crash logs.
• Resend (Resend, Inc., United States): sending of service emails (invitation, password).
• Google (Google LLC, United States), only if you link your calendar: Google Calendar.
• IGN, Géoplateforme public service (France): address search.
• Cloudflare (Cloudflare, Inc., United States): hosting of the euclium.com website.

Within Euclium, only authorised persons access the data, and only to the extent their role requires.

Where data are transferred outside the European Union, in particular to Expo, Resend, Google and Cloudflare, these transfers are governed by the EU–US Data Privacy Framework, to which these companies have adhered, and failing that by the standard contractual clauses adopted by the European Commission.

6. Retention periods

• User accounts: 3 years after the last sign-in, then deletion.
• Technical logs, including crash logs: 12 months.
• Client company data (leads, customer records): kept for the periods set by that company, then purged within 30 days after its contract is terminated.

7. Security

Exchanges between the app, the website and our servers are encrypted (HTTPS). Each company’s data are isolated at database level: a user can only access their own company’s data.

8. Your rights

Under the General Data Protection Regulation (GDPR) and the French Data Protection Act (loi Informatique et Libertés), you have the following rights over your data:

• access: to know which data concerning you are processed and to obtain a copy;
• rectification: to have inaccurate data corrected;
• erasure: to have your data deleted;
• portability: to receive your data in a machine-readable format;
• objection: to object to processing based on our legitimate interest.

To exercise them, write to admin@euclium.com, preferably from your account’s address. We reply within one month. If we have reasonable doubts about your identity, we may ask you for proof of identity.

To delete your account, follow the account deletion procedure.

If you believe your rights are not being respected, you can lodge a complaint with the French data protection authority, the Commission nationale de l’informatique et des libertés (CNIL), 3 place de Fontenoy, TSA 80715, 75334 Paris Cedex 07, France.
