Data privacy
Last updated: 4 November 2026
ArdhSolutions builds LardhGIS, LardhTraffic and LardhPedestrian. This page explains what we collect when you create an account, download and use our technologies, and what we do not collect. The short version: your maps, layers, projects and simulation results stay on your computer. We keep only what is needed to run your account and licence.
What we collect
- Account details: username, email address, and the full name and organisation you choose to add; whether you registered as a personal or business account; the apps you asked for.
- Sign-in security: your password is stored only as a salted hash, never in readable form. We record when you last signed in and used each app.
- Licence and computer: to keep a licence on one computer, the desktop app sends the computer name and an identifier derived from the machine (a hash, not the original value). We use it only to bind and check your licence.
- Orders and contact: the plan you order, the order number, your organisation, phone number and notes you type in, and your messages to us.
- Technical records: basic server logs (time, address and request) used for security and to keep the service running.
What we do not collect
- The contents of your projects, layers, simulations and exports. They are created and saved on your computer.
- Payment card numbers. Orders are paid by invoice or bank transfer arranged with our team; no card is stored on the website.
- Advertising or cross-site tracking data. We do not sell your data.
How we use it
- To create and secure your account, confirm your email and sign you in.
- To issue, bind and check your licence, and to tell the desktop app when a new version is available.
- To process orders and send you the payment details and your order number.
- To answer your questions and send service messages about your account. We do not send marketing email without your agreement.
Cookies and local storage
The website uses one session cookie to keep you signed in. Your language and theme choices are kept in your browser. We do not use advertising cookies.
Who can see your data
Only the ArdhSolutions team that runs the service and our email provider (which delivers account and order messages). We do not share your data with other parties unless the law requires it. If you use the AI assistant in LardhGIS with your own provider key, the questions you send go to that provider under its own terms, from your computer.
How long we keep it
We keep your account and licence records while the account exists. When you ask us to delete your account we remove your account, licence and device records; order records may be kept for the period our accounting rules require.
Security
The website is served over HTTPS, passwords are hashed, licence tokens are signed and tied to one computer, and administration is limited to the owner account.
Your choices
You can change your name, organisation and password from your account page. To see, correct, export or delete your data, write to info@ardhsolutions.com.
