2.3 Automatically Collected Data


  • Device type and operating system
  • App usage logs and crash reports
  • IP address


3. How We Use Your Data


We use your personal data to:

  • Create and manage your account
  • Match customers with the nearest available verified tradesman
  • Enable real-time GPS tracking during active jobs
  • Process payments and subscriptions via Stripe
  • Send push notifications about job status, matches, and payments
  • Verify tradesman identity and professional qualifications
  • Resolve disputes between customers and tradesmen
  • Comply with UK, Greek, and EU legal obligations
  • Improve the App based on usage patterns

We do not use your data for advertising or sell it to third parties.


4. Location Data


Customers: We collect your location when posting a job to find the nearest available tradesman. Location is not tracked continuously.

Tradesmen: When you accept a job and mark yourself as online, your real-time GPS location is broadcast to the matched customer for tracking purposes. This broadcasting stops when the job is completed or you go offline. You can withdraw consent at any time by toggling offline in the App, though this will prevent job matching.

Location data is stored as part of your job records for dispute resolution purposes and deleted after 12 months.


5. Third-Party Services


We share data with the following processors, all subject to GDPR-compliant data processing agreements:
