We act as the controller for the personal data described in this policy (account data, billing contacts, support correspondence, and similar). That is the ordinary role for PVMath as a SaaS product.
The project data you store on the Platform — site coordinates, parcel boundaries, slope and terrain figures, layout geometry, capacity, yield and economic parameters — is primarily geospatial and technical. In ordinary use it does not identify natural persons. Labels or free-text fields can still relate to identifiable people in edge cases. We do not collect landowner names, addresses, or other third-party personal data as a product feature — please do not enter such data into free-text fields.
We do not design the Platform as an Article 28 processing service where customers upload third-party personal data for us to process on their documented instructions. If your organisation still requires a data processing agreement (for example for account/admin contacts or a specific contractual arrangement), contact contact@pvmath.com — a DPA is available on request. See Terms § 9b for the contractual position. Roles ultimately depend on the purposes and means of processing in each case.
Wir sind Verantwortlicher für die in dieser Erklärung beschriebenen personenbezogenen Daten (Konto, Abrechnungskontakte, Support u. ä.). Die Plattform ist nicht als Auftragsverarbeitung nach Art. 28 DSGVO für hochgeladene Drittpersonen-Daten ausgelegt. Ein Auftragsverarbeitungsvertrag ist auf Anfrage verfügbar — contact@pvmath.com; siehe AGB § 9c.
When you create an account at app.pvmath.com, we collect your email address, optional name, and a hashed password. This is required to provide access to the platform.
If you save a project, we store project metadata you provide (project name, country, location label, site boundary coordinates, workflow settings, and analysis snapshots) in Supabase so you can reopen projects later. You can delete saved projects from your account.
We store counts of analyses and related product events for account administration, support, and product improvement. Paid plans are limited by named seats, not by analysis credits (see pricing). Legacy free accounts may still be limited to a small number of screenings without export.
If you submit the contact form on pvmath.com, we receive your name, email, company (optional), topic, and message. Submissions are transmitted via FormSubmit to contact@pvmath.com. We do not store form submissions in our application database beyond the email inbox and ordinary mail retention.
Account data, saved projects, and usage counts are stored in Supabase, hosted in the eu-central-2 (Zurich, Switzerland) region — a jurisdiction the European Commission recognizes as offering an adequate level of data protection under the GDPR. Privacy policy: supabase.com/privacy
