SCBA Squad Calc Privacy Policy Effective date: July 6, 2026 SCBA Squad Calc (the "App", published in Russian as "ГДЗС: расчёты") is a training calculator for iOS: it computes gas and smoke protection service (GDZS) squad parameters for work in breathing apparatus using the methodology of EMERCOM of Russia Order No. 640 of 27 June 2022, and shows the worked solution. All computation happens on your device. This Privacy Policy explains, plainly, what the App does and does not do with data. The App is provided by Sergey Makarov (the "Developer"). Questions: feedback@smkrv.net. Summary The App works fully offline. It collects no personal data, has no user accounts, no analytics, no telemetry, no advertising, and no tracking. The Developer runs no server that receives your data. The App makes no network connections on its own. The only time anything opens outside the App is when you tap the "Open the source" link on the methodology screen, which opens the normative document's text in your web browser - see section 3. 1. What the App does on your device - Calculations: pressures, squad composition, switch-on time and results are processed on your device. Nothing you enter is sent anywhere. - Journal: the App stores completed calculations (inputs, result and time) on your device only. You can delete entries at any time. - Apparatus: apparatus you add and their specifications are stored on your device only. - Settings: your appearance choice, pressure units, edits to the k and Q coefficients and your "verified by you" marks are stored on your device. This data never leaves your device. The Developer never receives it. 2. What the Developer does not collect The Developer does not collect, receive, store, or transmit: - the pressures you enter, squad composition, calculation results, or the journal; - your contacts, files, location, or device identifiers; - usage analytics, telemetry, or crash reports sent to the Developer; - any account information - the App has no accounts and no sign-in. The App contains no advertising and no third-party tracking or analytics software. 3. Network On its own the App makes no network connections: the calculations, formulas and apparatus specifications are bundled inside the App and need no internet. The methodology screen offers an "Open the source" link. If you tap it, the App opens the page with the normative document's text in your web browser. Nothing beyond that page's address is passed along, and the request is made by your browser, not the App. What the source website does with the visit is governed by its own privacy policy. If you never tap that link, the App makes no network connections. 4. If you obtained the App from the App Store Apple distributes the App and handles any purchases and updates. Apple may collect information about that under Apple's own Privacy Policy at https://www.apple.com/legal/privacy/. The Developer does not receive your identity from Apple; at most the Developer sees aggregate, non-identifying App Store statistics. 5. A note about results The App is a training tool for practice and self-checks. Data and formulas are shown as-is and require your own verification; calculation results are for training and are not meant for use in real emergencies or outside training self-checks. 6. Your rights The Developer holds no personal data about you, so in most cases there is nothing for the Developer to access, correct, export, or delete. The data you create with the App - the calculation journal, your own apparatus, coefficient edits - is on your device and under your control; you can view or delete it yourself at any time. 7. Children SCBA Squad Calc is a specialized training tool and is not directed at children. 8. Changes to this policy The Developer may update this Privacy Policy to reflect changes in the App or in applicable law. The effective date above shows when the current version took effect. 9.
