Accounts, authentication, contracted features, support and billing are processed to perform the contract or take pre-contractual steps. Tax and accounting records are processed to comply with law.
Security, abuse prevention and defence of legal rights rely on legitimate interests with minimisation safeguards. Google Analytics relies exclusively on consent and refusal does not restrict the service.
Visits to the Android application page, APK downloads and application opens are counted for distribution, integrity and operational support based on legitimate interests. The visitor identifier is cryptographically derived from technical data and does not expose the raw IP address to administrators.
On the first public visit, we derive only the approximate country locally from the IP address to propose the interface language. We do not use precise location, send the IP address to an external service for this operation, or store the result separately; a manually selected language always takes priority.
