Volsira
Privacy Policy
This policy covers Subnet Calculator and every other Android application published under the Volsira name. Volsira is operated by Muammer Aksu, an individual developer based in Türkiye.
What we collect
Nothing. Volsira applications do not collect, transmit, or store any personal information about you. There are no accounts, no sign-in, and no user profiles.
Data stored on your device
Subnet Calculator saves your calculation history so you can return to earlier results. This history is written to your device's local application storage and never leaves the device. It is not backed up to our servers, because we do not operate any servers.
You can erase this history at any time from the History screen. Uninstalling the app also removes it permanently.
Third parties
Volsira applications contain no advertising networks, no analytics services, no crash reporting services, and no third-party tracking of any kind. No data is shared with anyone, because none is gathered in the first place.
Network access
Subnet Calculator performs all calculations locally on your device and does not send network requests during normal use.
Children
Our applications are not directed at children under 13. Because we collect no personal information from anyone, we collect none from children either.
Your rights
Privacy laws such as the GDPR and the CCPA give you rights to access, correct, or delete personal data held about you. We hold no personal data about you, so there is nothing for us to retrieve or erase. Data stored on your device remains entirely under your control.
Changes to this policy
If a future release begins collecting data, this policy will be updated before that release ships, and the effective date above will change. Material changes will also be described in the app's release notes on Google Play.
