1. Data controller
The website gpx-edit-pro.ovh is published on a personal basis by Damien ANNE. For any question relating to the protection of your data, you can contact the controller at the following address:
2. Intellectual property
The source code, user interface, design, text and all content published on gpx-edit-pro.ovh are the exclusive property of GPX Edit Pro (Damien ANNE), unless explicitly stated otherwise. Any reproduction, representation, distribution or commercial use, even partial, is prohibited without the prior written permission of the rights holder. The open-source libraries used (Leaflet, JSZip, jsPDF, etc.) remain subject to their own respective licences.
3. Data collected
GPX Edit Pro collects no personal data. The tool runs entirely in your browser (client-side processing, JavaScript). Files you import (GPX, FIT, TCX, KML) are never transmitted to a remote server: they stay on your device and in your browser's temporary memory for the duration of the session.
Certain optional features (elevation correction, route calculation, weather) transmit only the GPS coordinates needed for the calculation to public third-party APIs. No personal data is ever attached to these requests.
4. Cookies and trackers
This site uses no cookies, no advertising trackers and no audience-measurement tools (Google Analytics, Matomo, etc.). No persistent session identifier is ever placed on your device.
5. Local storage (sessionStorage)
To preserve your work if the page reloads, the application uses your browser's sessionStorage to temporarily save tracks you're mid-edit on. This data is stored locally on your device, never on a server, and is automatically cleared when the tab or browser closes.
In accordance with Article 5 of ePrivacy Directive 2002/58/EC (transposed into Article L.32-3 of the French Postal and Electronic Communications Code), this strictly functional, session-only storage does not require prior consent.
6. Track-sharing feature
The link and QR-code sharing feature — whether for a track or a 3D view — involves transmitting and storing your route in a hosted JSON file on OVHcloud's servers. This storage is technically necessary: without it, the recipient of the link could not view the track. No other feature sends your files to a server. This data is stored with no information that could personally identify you, and is accessible only via the unique URL generated. To request deletion of a shared track, you can contact the controller at the address given in section 1.
7. Hosting
The site is hosted by OVHcloud (SAS, 2 rue Kellermann, 59100 Roubaix, France), a European provider subject to the GDPR. OVHcloud may collect technical access logs (IP address, timestamp, URL) for security and maintenance purposes, in line with its own legal obligations. These logs are kept for a maximum of one year.
8. Legal basis (GDPR)
Since GPX Edit Pro itself collects no personal data, Regulation (EU) 2016/679 (GDPR) does not directly apply to the processing carried out by the tool. Any processing carried out by the host relies on legitimate interest within the meaning of Article 6(1)(f) GDPR.
9. Your rights
Under the GDPR and French Data Protection Act No. 78-17 of 6 January 1978 (as amended), you have the following rights: access, rectification, erasure, restriction, objection and portability. Since no personal data is stored by this service, exercising these rights applies only to the hosting provider's logs, for which you can contact OVHcloud directly.
You also have the right to lodge a complaint with the CNIL (French Data Protection Authority) — www.cnil.fr.
10. Security
All exchanges between your browser and the server are encrypted via HTTPS/TLS. Since your GPS files never pass through our servers during editing, they are exposed to no risk of a server-side data leak.
11. External links
This site contains links to third-party sites (OVHcloud, CNIL, etc.). GPX Edit Pro does not control the content of these sites and accepts no responsibility for their privacy practices. Visiting these sites is subject to their own privacy policies.
12. Disclaimer — Limitation of liability
Data provided by GPX Edit Pro — altitudes, surfaces, distances, elevation gain, weather forecasts, route suggestions — is provided for guidance only, drawn from third-party sources (OpenStreetMap, EU-DEM/Copernicus, SRTM, Open-Meteo). GPX Edit Pro guarantees neither the accuracy, nor the completeness, nor the fitness of this information for any particular purpose.
Any decision relating to outdoor activities — particularly in the mountains, on technical trails, or in difficult weather conditions — remains the sole responsibility of the user. GPX Edit Pro cannot be held liable for any direct or indirect damage resulting from the use of this data.
13. Governing law
This policy is governed by French law.
14. Changes
This policy may be updated to reflect changes to the service or to applicable regulations. The date of the last update is shown at the top of this document.
15. Technical details
This section is published for information, to allow the privacy commitments described above to be verified in concrete terms.
Architecture. The editor is a web application with no framework and no application server: HTML, CSS and JavaScript run in your browser. Reading GPX, FIT, TCX and KML files, editing, ascent calculation, simplification and export generation all happen entirely client-side. No account, no user database.
Libraries used. Leaflet (mapping), Three.js (3D relief visualisation), jsPDF and html2canvas (PDF export), JSZip (archives). These libraries are served from the site's own domain, not from a third-party CDN. Typefaces (Archivo, JetBrains Mono) are hosted locally: no request is ever sent to Google Fonts.
External services called. These services receive only the geographic coordinates needed for the requested calculation — never your file, never any personal data: OpenStreetMap and map-tile providers; BRouter and OSRM for route calculation; Nominatim for search and reverse geocoding; the Overpass API for points of interest; Open-Meteo for forecasts; EU-DEM / Copernicus and SRTM for elevation correction; PMTiles vector tiles for surface detection.
Hosting and storage. Site hosted with OVHcloud (France). Track sharing relies on flat JSON files, with no database. The source code is not public.
