Privacy policy
As of October 2026
Controller
The data controller is Lestra Engineering AG, Grabenmattweg 4, 3436 Zollbrück, Switzerland. Data-protection contact: support@leglink.ch.
Data we process
We process account and contact data, platform usage data, and the LEC, metering-point and billing data you enter.
Purposes and legal bases
Processing serves contract performance, compliance with legal obligations (incl. the Swiss CO and GeBüV) and legitimate interests, in line with the revised Swiss Data Protection Act (revDSG).
Disclosure to third parties
We only share data with carefully selected processors (hosting, payment, email delivery) that are contractually bound to confidentiality. The exceptions are swisstopo's map services and, if you show one of its maps (rebate areas or vZEV), the grid operator's, which your browser calls directly (see “Map of a municipality's LEGs”).
Map of a municipality's LEGs
When a LEG is made visible, signed-in users see it on its municipality's map: with its name, pitch, number of participants and, from three participants on, the total PV capacity. We show the participants' location only approximately, as one circle per building whose centre is moved by 60 to 150 metres. Names, addresses and exact positions are not shown.
Your browser loads the map, the municipal boundaries and the municipality for a click on the map directly from the Federal Office of Topography swisstopo (geo.admin.ch). For technical reasons, swisstopo receives your IP address and the map section shown or the point clicked; we do not pass on any other data.
If you show one of the grid operator's maps on this map (currently BKW: rebate areas or vZEV), your browser loads that map directly from the grid operator. For technical reasons, the grid operator receives your IP address and the map section shown; we do not pass on any other data. Without such a map shown, the grid operator is not contacted.
Data location
Processing and storage take place in Switzerland. For any disclosure abroad we ensure adequate protection through appropriate safeguards.
Retention
We retain personal data only as long as necessary for the stated purposes or required by statutory retention periods.
Your rights
You have the right to access, rectification, erasure, restriction, data portability and objection. You may also lodge a complaint with the FDPIC.
Cookies and analytics
We use technically necessary cookies. Analytics or marketing tools are only used with your consent.
