1. No-account analysis
Core analysis in FresnelPath works without creating an account. You can place a gateway, run a full ITU-R path analysis, and export results without providing any personal information. No registration wall, no email required.
When you use the tool anonymously, the only data recorded is usage telemetry (see §2 below).
2. Telemetry we collect
FresnelPath collects anonymous usage telemetry to understand how the tool is used and to maintain service reliability. The categories of data collected are:
- Analysis parameters: selected country, LoRaWAN region, frequency band, and propagation model. These help us understand which regions and use cases the tool serves.
- Gateway location: the latitude and longitude of the gateway you place on the map. This is stored at analysis time for debugging and quota purposes. We do not build profiles of individual users' deployment sites over time.
- Request timing: how long analysis requests take to complete. Used to identify performance regressions.
- Error events: when an analysis fails, the error category (not the full stack trace or your inputs) is logged. Used to identify defects.
- Feature usage: which tabs, export formats, and analysis types you use. Used to prioritize development.
Telemetry is not linked to a personally identifiable identifier for anonymous sessions. We do not sell telemetry data to third parties.
3. Accounts
If you create a FresnelPath account, we store your email address and a hashed password for authentication. Your saved projects (analysis configurations, node placements, named gateways) are stored and associated with your account.
You can delete your account at any time by contacting us. Account deletion removes your email, authentication credentials, and all saved project data.
4. Share links
When you create a public share link for an analysis, the analysis snapshot is stored and accessible at a public URL. Share links are blocked from indexing by search engines (see /robots.txt). If you share a URL with someone, they can view the analysis. Anyone with the URL can view it — treat share links like any other link-shared document.
You can delete your share links from the app interface at any time.
5. Third-party services
FresnelPath uses the following third-party services during operation:
- Formspree — processes messages submitted through contact forms on this site. Your name, email, and message are forwarded to Formspree's servers. See Formspree's privacy policy for details on their data handling.
- PVGIS (European Commission) — when you run a solar analysis, the candidate site coordinates are sent to the PVGIS API to retrieve irradiance and battery autonomy data. No other user data is forwarded. PVGIS is operated by the EU Joint Research Centre.
- Copernicus / AWS CloudFront — elevation data for your analysis path is fetched from public Copernicus GLO-30 tiles. The tile requests include geographic coordinates (the bounding box of your analysis). No user-identifying data is included in these requests.
- OpenStreetMap / MapLibre tile sources — map tiles for the interface are loaded from public tile services. Tile requests include the geographic area you are viewing. No user-identifying data is included.
FresnelPath does not ship Google Analytics, Sentry, Segment, or similar third-party analytics SDKs in the landing page or the application. This statement is verifiable by inspecting the page source.
6. Cookies and local storage
FresnelPath uses browser local storage (not cookies) to persist your analysis state between sessions — the map position, selected country, frequency preset, and analysis parameters you last used. This data stays in your browser and is not transmitted to our servers except as part of an analysis request.
Authentication sessions use a secure, HTTP-only session token. It is not accessible from JavaScript.
7. Data deletion
To request deletion of your account, associated project data, or a specific share link, contact us via the form on the press page. State clearly what you want deleted. We will process the request within 10 business days.
Anonymous telemetry records cannot be linked back to you after the session ends, so they cannot be specifically deleted — they are aggregated and age out of the system on a rolling basis.
8. Changes to this policy
This policy will be updated if we change what we collect or how we handle it. The "Last updated" date at the top will change. We will not retroactively apply new data practices to data already collected.
