Privacy Policy

1. The Short Version

• SimulATe performs all calculations locally on your computer. Your project files, drawings and results never leave your machine unless you explicitly export or share them.
• This website uses no cookies, no analytics and no advertising trackers. The only thing stored in your browser is your language preference (localStorage).
• We do not sell, rent or trade any personal data. Ever.

2. Who We Are

SimulATe Engineering Software is developed and operated by Akin Turcan (Belgium) — the data controller for the processing described in this policy. Contact: info@simulate-software.com.

3. This Website (simulate-software.com)

3.1 Hosting

The site is a static website hosted on Cloudflare Pages. Like any web server, Cloudflare technically processes your IP address to deliver the pages and to protect against abuse. Cloudflare acts as our infrastructure provider under its own privacy policy. We run no server-side code and keep no visitor database.

3.2 Fonts

Page fonts (Inter, JetBrains Mono) are loaded from Google Fonts. When your browser requests these font files, your IP address is technically visible to Google, which acts as an independent controller under the Google privacy policy. No other Google service (analytics, ads, tags) is used on this site.

3.3 Contact form

If you use the contact form, the name, e-mail address, subject and message you enter are relayed to our mailbox (info@simulate-software.com) via the FormSubmit relay service. We use this data solely to answer your message and keep the correspondence only as long as needed for that purpose. Legal basis: GDPR Art. 6(1)(b) — steps taken at your request.

3.4 Purchases

Checkout, billing and subscription management are handled entirely by Lemon Squeezy, our merchant of record. Your payment details are entered on Lemon Squeezy's pages and are never visible to us; we receive only the information needed to issue and manage your license (name, e-mail, license key, subscription status). See the Lemon Squeezy privacy policy.

3.5 What we deliberately do not do

No cookies. No analytics or measurement scripts. No advertising or social-media pixels. No newsletter tracking. Your language choice is stored only in your own browser's localStorage and is never transmitted.

4. The Desktop Application

4.1 Local by default

All engineering calculations run locally. Project files, calculation results, drawings and reports are stored on your computer and are not transmitted to any server, except in the specific user-visible cases below. The built-in AI Copilot is a fully local, rule-based assistant — your questions and chat history never leave your computer.

4.2 License activation & verification

When activating or verifying a license, the application transmits your license key, an anonymous one-way hardware hash (Computer ID — not reversible to identify hardware components) and the software version to the license service. No project data is ever included. Legal basis: GDPR Art. 6(1)(f) — legitimate interest in license enforcement. Retention: for the duration of the license.

4.3 Weather display (optional)

The home screen may contact two third-party services to suggest a local ambient temperature: an approximate IP-location service (ipwho.is) and a weather service (open-meteo.com). As with any internet request your IP address is technically visible to these services, which act as independent controllers. No project data, personal identifiers or license information is sent. Without internet access the feature is silently skipped.

4.4 Document timestamping (user-initiated)

If you use the timestamp-proof feature, only a cryptographic hash (digest) of the document is sent to public OpenTimestamps calendar servers. The document itself never leaves your computer and the hash cannot be reversed to reconstruct its content.

4.5 Crash reports (manual only)

Error reports are sent only if you choose to send them, via e-mail. They contain the error type and traceback, software version, operating system and the tray configuration at the time of the error (dimensions only — no personal data, no project content). Nothing is ever sent automatically.

4.6 No telemetry

The application contains no usage tracking, analytics, advertising identifiers or hidden "phone home" mechanisms of any kind.

5. QR Field Labels & Online Share

5.1 QR field labels

The calculation snapshot shown when a printed QR label is scanned is encoded, compressed and integrity-signed inside the QR code itself. The decoder page (simulate-decoder.pages.dev) decodes it locally in your browser with JavaScript. We do not store QR snapshot data on our servers, and the decoder keeps no database of scanned labels. Treat a printed QR label like the paper drawing it replaces: anyone who can physically scan it can read the engineering data it carries.

5.2 Online Share (user-initiated)

If you explicitly use the "Share Online" feature, a snapshot of the selected calculation section is uploaded to our share endpoint and a short link is returned. Shared snapshots expire and are automatically deleted after approximately 90 days. Anyone who obtains the link can view the snapshot — do not share confidential project data. No project is ever uploaded automatically. Legal basis: GDPR Art. 6(1)(b) — performance of your request.

6. Your Rights (GDPR)

If you are in the EU/EEA, you have the rights set out in GDPR Articles 15–22: access, rectification, erasure, restriction of processing, data portability and objection. To exercise any of these rights, e-mail info@simulate-software.com. You may also lodge a complaint with the Belgian Data Protection Authority (GBA/APD): www.dataprotectionauthority.be.

7. Changes & Contact

We may update this policy as the product evolves; material changes will be announced on this page with a new "last updated" date. Questions about this policy or about data protection: info@simulate-software.com.
