This Privacy Policy describes Our policies and procedures on the collection, use and disclosure of Your information when You use the Service and tells You about Your privacy rights and how the law protects You.
We use Your Personal Data to provide and improve the Service. Using the Service does not constitute consent to optional telemetry or advertising tracking. These choices are made separately.
The words of which the initial letter is capitalized have meanings defined under the following conditions. The following definitions shall have the same meaning regardless of whether they appear in singular or in plural.
For the purposes of this Privacy Policy:
Affiliate means an entity that controls, is controlled by or is under common control with a party.
Application means the software program provided by the Company downloaded by You on any electronic device, named DR-DeviceTools.
Company (referred to as either "the Company", "We", "Us" or "Our") refers to DR-ONLINE SP. Z O.O., Aleje Jerozolimskie 155/U3, 02-326 Warsaw, Poland (VAT/NIP PL5223068517).
Country refers to: Poland.
Device means any device that can access the Service.
Personal Data is any information that relates to an identified or identifiable individual.
Service refers to the Application.
Service Provider means any natural or legal person who processes the data on behalf of the Company.
Usage Data refers to data collected automatically through the use of the Service.
You means the individual using the Service, or the entity on behalf of which such individual is using the Service.
The Application has no user account and does not ask for Your name or email address. Technical identifiers and IP addresses may constitute personal data even when we do not know your name. If you contact us by email, we process the information you provide to respond.
The Application is a diagnostics toolbox: it reads information about the device it runs on and shows it to you. Depending on the screen, this includes the processor, memory and storage, battery state, display, graphics, thermal readings, sensors, cameras and audio hardware, supported media codecs, USB and Bluetooth capabilities, network interfaces and connectivity details, and security features. Some readings need a system permission (for example location for Wi-Fi and satellite details, Bluetooth, camera or microphone metadata, local network access, or physical activity and body sensors for live step-counter and heart-rate readings); your operating system asks before they are granted, and refusing only hides the readings that depend on them. Step counts and heart-rate readings are shown on the device while the sensor row is open; the Application does not store them and does not send them anywhere. The hardware test can use the microphone to show a live input level and the camera to show a live preview while you check them; the sound and the picture are shown on the device only and are never recorded, stored or sent anywhere.
These readings are shown on your device and are not transmitted to Us or to any third party. They are not stored by the Application beyond what is needed to display and refresh the screen you are looking at. Benchmark and test results are shown to you and kept only on your device.
The only server operated by Us that the Application contacts is Our licence service, used to confirm purchases as described under "Purchases" below. Each such request necessarily carries your IP address and basic connection metadata, which We keep only in ordinary server logs for security and troubleshooting.
On Android and iOS, optional telemetry is disabled until you make a choice. You can separately enable "Crash reports" and "Usage statistics". Both choices are initially off. Refusing does not limit any feature of the Application, free or paid. You can change either choice in Settings. An earlier default-enabled setting is not treated as consent; an earlier explicit opt-out is respected.
Optional telemetry is processed on the basis of your consent (Art. 6(1)(a) GDPR). Google Firebase receives the selected data to help us diagnose failures and understand and improve the Application. Data can contain installation or app-instance identifiers and is not described as anonymous. We disable the use of these Analytics data for advertising personalization, and the Application never sends the device readings or your benchmark results as part of telemetry.
If enabled, Firebase Crashlytics receives error stack traces, app and device information (model, operating system version, application version), the screen that was open and whether the paid version is active, and installation identifiers. Crash reports may be stored locally and transmitted on a subsequent launch if crash reporting remains enabled.
Automatic Crashlytics uploads are disabled. Pending reports are discarded when crash reporting is disabled. Withdrawing your choice stops future optional reporting; it does not recall data already transmitted or a transmission already in progress. Crashlytics can keep crash records locally even when sending is disabled.
If enabled, Firebase Analytics collects app-instance identifiers, device/app details, screen and feature usage, session information, benchmark and test runs, and purchase-flow events (such as viewing an offer, starting or completing a purchase). The same choice covers Firebase In-App Messaging, which uses these events to show occasional messages inside the Application and records whether they were displayed or tapped. This service follows the separate "Usage statistics" choice. It is not enabled by the crash-reporting choice or the advertising choice.
For service data, retention periods and processing details, see Firebase Privacy and Security and Google Privacy Policy. Firebase Crashlytics retains crash traces and associated identifiers for 90 days before beginning removal. Analytics retention depends on the Analytics property configuration. Contact us for information or to exercise your data rights.
The Application offers optional paid features. Payments are processed entirely by Google Play or the Apple App Store — We never receive or store your payment card details.
To confirm that a purchase entitles you to the paid features, the Application sends the store's purchase token to Our licence service. We store the fact that a purchase exists, the product purchased, and its status. This lets Us restore your purchase on a new device and honour it briefly while your device is offline. This processing is necessary to perform the contract with you (Art. 6(1)(b) GDPR).
We display advertisements in the free version of the Application using Google AdMob. AdMob may collect and process certain data to serve ads, including:
Depending on your consent choices, you may receive:
In the European Economic Area, the United Kingdom, Switzerland and US states whose laws require it, the Application asks for your advertising choices through Google's consent form (Google User Messaging Platform, a certified consent management platform) before any ads are requested. On iOS, the system tracking permission (ATT) is requested only after that form, and not if you have refused consent in it.
You can manage your ad preferences at any time through the Application settings ("Manage Ad Preferences", shown where these laws require it) or through your device settings:
Processing of advertising data is based on your consent (Art. 6(1)(a) GDPR). Advertising choices are separate from telemetry choices. Non-personalized ads may also require consent; withdrawing consent does not automatically authorize another form of advertising data collection. The iOS tracking permission (ATT) is a separate system permission. The paid version of the Application shows no advertisements.

We process your data only when we have a legal basis, including:
Under GDPR, You have the right to:
To exercise your rights, contact us at: [email protected]
We may use Personal Data for:
Providing and maintaining the Service, including answering the requests described above and confirming your purchases.
Contacting You: To respond when You contact Us.
Analyzing how the Service is used via Firebase Analytics, when You have enabled usage statistics, to improve our Application.
Diagnosing failures via Firebase Crashlytics, when You have enabled crash reports.
Displaying advertisements: To show you ads through Google AdMob in the free version, based on your consent preferences.
We do not share your personal data with third parties except in the following cases:
The Company will retain Your Personal Data only for as long as is necessary for the purposes set out in this Privacy Policy. We will retain and use Your Personal Data to the extent necessary to comply with our legal obligations, resolve disputes, and enforce our legal agreements and policies.
Purchase records are kept for as long as the purchase is valid and as required by tax law. Server logs of the requests described above are kept for a short period for security and troubleshooting. Firebase retains telemetry data per its policies, as described above.
Your information, including Personal Data, is processed at the Company's operating offices and in any other places where the parties involved in the processing are located. It means that this information may be transferred to — and maintained on — computers located outside of Your state, province, country or other governmental jurisdiction where the data protection laws may differ than those from Your jurisdiction.
Firebase and its infrastructure may transfer data outside the European Economic Area. Such transfers are secured by standard contractual clauses or other legal mechanisms accepted under GDPR.
Accepting optional telemetry does not waive your rights regarding international transfers.
The Company will take all steps reasonably necessary to ensure that Your data is treated securely and in accordance with this Privacy Policy and no transfer of Your Personal Data will take place to an organization or a country unless there are adequate controls in place including the security of Your data and other personal information.
If the Company is involved in a merger, acquisition or asset sale, Your Personal Data may be transferred. We will provide notice before Your Personal Data is transferred and becomes subject to a different Privacy Policy.
Under certain circumstances, the Company may be required to disclose Your Personal Data if required to do so by law or in response to valid requests by public authorities (e.g. a court or a government agency).
The Company may disclose Your Personal Data in the good faith belief that such action is necessary to:
We use reasonable safeguards to protect Your information. However, no method of transmission over the Internet, or method of electronic storage is 100% secure. While We strive to use commercially acceptable means to protect Your Personal Data, We cannot guarantee its absolute security.
Our Service is not intended for users under 13. We do not knowingly collect data from children under 13. If you believe we have, please contact us to delete it.
If We need to rely on consent as a legal basis for processing Your information and Your country requires consent from a parent, We may require Your parent's consent before We collect and use that information.
Our Service may contain links to other websites that are not operated by Us. If You click on a third party link, You will be directed to that third party's site. We strongly advise You to review the Privacy Policy of every site You visit.
We have no control over and assume no responsibility for the content, privacy policies or practices of any third party sites or services.
We may update this Privacy Policy. Updates will be posted here and, where appropriate, notified to you via the Application.
You are advised to review this Privacy Policy periodically for any changes. Changes to this Privacy Policy are effective when they are posted on this page.
