Maps and projects loaded in the application
JPEG, PNG and WebP files loaded from your device are stored locally in the browser, notably through IndexedDB. Without an account, they are not uploaded to the GeoCalque server. Project settings and preferences are stored locally so work can be resumed. Complete .geocalque exports are built in the browser and include the project images.
When you import an IIIF resource, the image is requested directly from the IIIF server you specify. That third-party server therefore receives the browser request.
Account and cloud save
Creating an account is optional. If you explicitly choose Save to cloud, a complete project archive including local images and georeferencing data is uploaded to GeoCalque and stored in private storage outside the public web directory. E-mail address, login sessions, project metadata and quota information are processed to provide this service.
Passwords are never stored in plain text. Sharing links use random, unindexed tokens; anyone with an active link may access the shared version. The project owner can delete the project, invalidating its shared access.
Geolocation
Use my location is optional and requires browser permission. In the current France-specific helper, coordinates may be sent to geo.api.gouv.fr to identify a municipality. GeoCalque keeps only useful place/centering information, not your precise GPS position.
External basemaps
Map tiles are loaded from providers identified in the interface, including OpenStreetMap, OpenTopoMap and, for France-specific layers, IGN/Géoplateforme. As with any remote web resource, these providers receive the IP address and technical request information required to deliver tiles.
Server logs
The server may record standard technical logs including IP address, date/time, requested URL, response code and browser information. They are used for security, diagnostics and internal traffic statistics. The intended production configuration limits retention to a maximum of 30 days, except where a specific security need requires otherwise.
Contact form
When you use the contact form, category, optional name/e-mail, subject, message, referring page and browser information are sent to the server so the message can be delivered by e-mail. The form content is not stored in a GeoCalque database. Temporary anti-abuse counters based on a non-reversible IP fingerprint may be kept for a few days.
Cookies and analytics
GeoCalque does not use an advertising network or third-party analytics service at launch. Local storage required for project saving/preferences stays on your device. Internal traffic statistics are based on local analysis of server logs.
Retention and deletion
Browser projects remain until you delete them or clear site data. Cloud projects remain associated with the account until deletion; several recent versions may be retained for restoration. Server logs follow the retention period above.
Your rights
For questions or to exercise rights concerning data processed by the GeoCalque server, contact mathiaspaicheler@hotmail.com. Data stored only in your browser is not accessible to the site operator.
Annotations, photos and public contributions
Annotations are private by default, saved locally or in your private cloud project. Personal annotations are excluded from project archives delivered through GeoCalque sharing links.
If you explicitly choose to publish an annotation, its title, description, geometry and optional photo become accessible to people who enable the public heritage layer. Published photographs are recompressed to remove embedded metadata. You can withdraw publications at any time from the project or your account.
Public contributions can be reported and hidden for moderation.
