Privacy Policy
Last updated: May 9, 2026 · Version 1.0
1. Preamble
TruckerMaster (hereinafter “the Application”) is a web and mobile application intended for professional truck drivers. It is published in a non-professional capacity by a working truck driver (cf. legal notices). This policy describes how your data is collected, processed and stored in compliance with the General Data Protection Regulation (GDPR — EU Regulation 2016/679).
2. Data processed
The Application processes the following data when you use it:
- Driver card data (chronotachygraph): surname, first name, card number, validity dates, issuing authority, vehicle identifiers, places of service, driving/working/rest hours.
- Payslip data (extracted by OCR from your scans): hourly rate, hours paid, allowances, bonuses, gross salary.
- Manual entries : company name, permit number, full name, collective agreement parameters.
3. Data storage
100% of your data remains stored locally on your device (web browser or phone), via LocalStorage / IndexedDB technology. No data is sent to a remote server in the current version.
An option of encrypted cloud backup will be offered in future versions. She will stay strictly optional and will require your explicit consent.
4. Reading the driver card
Reading your driver card goes through a local software bridge (pcsclite) installed on your computer. This bridge only communicates with your browser, on the address localhost. No card data passes over the internet.
5. Optical recognition (OCR) of pay slips
The OCR of the files uses Tesseract.js, an open source library that runs entirely in your browser. Your pay slip images are not never uploaded to a third-party server.
6. Cookies and trackers
The Application does not use no advertising cookies or third-party trackers (Google Analytics, Facebook Pixel, etc.). The only local storage used is necessary for the operation of the app (preferences, history).
7. Your rights (GDPR)
In accordance with the GDPR, you have the following rights over your data:
- Right of access — you can export all your data from Settings → Tools → “Export my data” (readable JSON format).
- Right of rectification — all values can be edited manually in the app.
- Right to erasure — Settings → Tools → “Clear entire cache” deletes all your data from your device.
- Right to portability — JSON export includes all of your data in an open and standard format.
8. Security
Since your data is stored locally on your device, its security depends mainly on the security of this device (screen lock, antivirus). We recommend:
- Do not share your device without precautions.
- To use a password/biometric lock on your phone.
- To purge the app via Settings → Tools in the event of resale of the device.
9. Preservation
No server-side retention period (no server). The data remains on your device until you delete it yourself or uninstall the app.
