2. Data Collected
2.1. Data Provided Directly by the User
When logging in or using the service, the following data may be collected:
- First and last name
- Company name
- Postal address
- Email address
- Landline and/or mobile phone number
Login is passwordless.
The user authenticates solely via a one-time code (OTP) sent by email, securely managed by Supabase Auth.
No password is created, stored or processed by CODALUX.
2.2. Data Related to NFC Plates / QR Codes
When an NFC plate or QR Code is scanned, the following data may be recorded:
- scan date,
- scan time,
- device type used (e.g., Android, iOS),
- browser type used (e.g., Safari, Chrome, Firefox, etc.).
This data is completely anonymous and cannot in any way identify an end user. No personal identifier is collected during a scan.
2.3. Technical and Usage Data
- IP address
- Device type and operating system
- Connection logs
- Actions performed on the website or in the application (e.g., modification of review links)
2.4. Website Audience Measurement
The website counts its visits in order to know its actual audience. This measurement complements Google Analytics statistics, which only cover visitors who accepted analytics cookies.
For the first visit of each session, the following is recorded:
- the truncated IP address: the last group of digits is replaced by zero, which designates a range of addresses rather than a device,
- the country,
- the browser, the operating system and whether the device is mobile,
- the page viewed and the referring page.
The full IP address is never stored. The browser's technical identifier ("user-agent") has no longer been kept since 13 September 2026: only the three facts derived from it are. Values recorded before that date are erased by the automatic 90-day deletion, by 12 December 2026 at the latest.
A cookie named maf_vlog prevents the same visit being counted twice. It is a session cookie: it disappears when the browser closes. It contains no identifier, only the value "1", it is inaccessible to page scripts, and it is read by no other website.
This data is kept for 90 days, then deleted automatically. It is used solely to produce counts, is cross-referenced with no other processing, and is passed to no one.
This measurement does not require your consent, under the exemption provided for audience measurement tools, whose conditions it meets: a purpose limited to audience measurement on our own behalf, anonymous statistics, no cross-site tracking, and short retention periods.
2.5. Location Data
No geolocation data is collected.
The application does not access the user's GPS location.
2.6. Data Collected via the Mobile Application
- Push notifications: yes
- Camera access: yes (solely for scanning QR Codes)
- Storage access: no
- NFC access: no
- Advertising tracking (ATT): no
- Update checks: when opened and when brought back to the foreground, the application asks Expo's service whether a new version is available (see section 5)
2.7. Website Cookies and Trackers
Set without consent, as they are necessary for the service:
cc_cookie: stores your cookie choices. Kept for 6 months.detected_country: country inferred from your connection, used to offer the right language and support phone number. Kept for 1 year.maf_vlog: visit counting, described in section 2.4.maf_ref: when you reach the website through a link from a Mon Avis Facile business introducer, this cookie stores that introducer's code so the sale can be credited to them and their commission calculated. It only contains this code, no data about you, is not read by any other website and expires after 30 days.
Set only with your consent:
- Statistics: Google Analytics cookies (
_ga,_gid), themaf_vidcookie (random visitor identifier, kept for 90 days) and themaf_touchpointshistory stored in your browser (source of your last 50 visits). They measure the effectiveness of our acquisition channels. - Marketing: Google Ads cookies (
_gcl_*), which measure the conversions of our advertising campaigns.
You can change your choices at any time with the "Cookie settings" link at the bottom of every page. When you refuse or withdraw your consent, the cookies and trackers of that category are deleted from your browser.
