Privacy for Calculator 365
These notices cover the Calculator 365 app for iPhone, iPad and Android and its pages on srmedia.app. Local calculations, store functions and Google services are described separately.
Controller & contact
The controller is SR-Media, Stefan Remberg. The legal notice provides the address and legally required contact details. For Calculator 365 and privacy questions, email hello@srmedia.app.
Calculations and local app storage
The calculation functions process your inputs on the device. Calculation history, including inputs, results, timestamps and your labels, calculator settings, custom buttons and layouts are saved in local app storage. Language, onboarding steps, counters for limited free uses and information about unlocked features are also held there.
The reviewed calculation path does not upload history to an SR-Media calculation server. Store and advertising functions continue to use external services. Disabling Firebase Analytics and Crashlytics for this release does not disable those separate processing activities. Operating-system backups may also include local app data.
Purchases and unlocking features
Purchases and subscriptions are handled by Apple App Store or Google Play. The app processes product and transaction information, the current entitlement status and, where provided by the store, subscription expiry to enable Pro features and restore purchases. The app does not receive payment card details. The store processes account and payment information under its own responsibility.
The locally cached entitlement status is checked against store information. Uninstalling does not delete store purchase records or cancel a subscription.
Advertising videos and Google Mobile Ads
Google Mobile Ads is included for optional advertising videos. It may process and transmit to Google information including the IP address and approximate region derived from it, device and advertising identifiers, advertising views and interactions, and technical performance and diagnostic data. These are used to deliver and measure advertising and prevent abuse. Ads may involve additional advertising partners.
Watching an advertising video is optional. Advertising privacy choices are updated when the app starts. Once UMP permits ad requests, the advertising SDK can also be initialized; its processing therefore does not necessarily begin only when a video starts. Banners and automatically displayed full-screen ads are disabled in this version.
Before requesting ads, the app checks the current permission status provided by Google's User Messaging Platform (UMP). Where UMP requires a privacy-options entry point, the app displays it under About in Settings. Advertising choices do not replace any separately required Apple tracking permission.
Firebase Analytics and Crashlytics are disabled
Firebase Analytics and Firebase Crashlytics are disabled in Calculator 365 1.0.8 (build 36). App startup does not activate these services, and their native collection controls are off. The app therefore does not use these services for usage analytics or crash reports. Google Mobile Ads and its consent management remain separate; their processing is described in the advertising section.
Website and email contact
When these static pages are requested, technically necessary connection data such as the IP address and requested address are transmitted to the webservers involved. The fonts, images and scripts of these pages are served from srmedia.app. This website source includes neither an analytics pixel nor a website integration of AdMob or Firebase.
When you contact us by email, your sender address, message and any information you provide are processed to handle your request. Provide only the information needed for your enquiry.
When you contact us by email, we process your sender address and message to handle your request. Include only the information needed for that purpose.
Purposes and legal bases
Providing the requested app functions locally and processing the store information needed to unlock Pro and restore purchases serve the relevant app and purchase services (Article 6(1)(b) GDPR, to the extent personal data is processed). Where advertising processing requires consent, Article 6(1)(a) GDPR applies; consent-dependent storage or access on your device additionally falls under section 25(1) TDDDG. Choosing an optional advertising video does not replace that consent.
Withdrawal applies to future processing and does not retrospectively invalidate earlier lawful processing.
Recipients and processing outside the EEA
Recipients can include Apple and Google as store providers, Google for advertising and the partners identified in the advertising dialog. Depending on the service and account, group companies and service providers outside the European Economic Area, particularly in the United States, may also process data.
Google describes its role for the standard AdMob service in its Controller-Controller Data Protection Terms. These terms identify Google Ireland Limited as Google's controller for European personal data. Google describes a worldwide infrastructure for its advertising services. For international transfers, Google identifies mechanisms including the EU-US Data Privacy Framework and, where applicable, standard contractual clauses. Its transfer information explains the mechanisms and safeguards it describes. Other advertising partners actually involved have their own notices.
Retention and deletion
Local settings remain until changed or the corresponding app data is removed. History entries can be deleted individually or cleared completely, and the app limits the total number stored. Device backups, shared content and records held by Apple, Google and other recipients have their own deletion options and retention rules.
Your rights
Where the legal requirements are met, you may request access, rectification, erasure, restriction and portability, and object to processing based on legitimate interests. You may withdraw consent for future processing. Email hello@srmedia.app to make a request.
You may also complain to a data-protection supervisory authority, particularly where you normally live, work or believe an infringement occurred. The State Commissioner for Data Protection and Freedom of Information North Rhine-Westphalia is an appropriate authority for the operator based in that German state.
