Privacy Policy for Atag One Control

Effective Date: January 25, 2023


In contrast to the majority of products, our Privacy Policy for Atag One Control is brief and transparent.
This Privacy Policy applies to our mobile application Atag One Control (our “Service”).
Please do not install or use Atag One Control if you do not agree to this Privacy Policy.

The Service allows you to control and monitor your ATAG One thermostat. To achieve this, the app communicates via a secured HTTPS connection with the ATAG server. All results are shown in the Service and do not leave your device in any way.


i) The Service uses Firebase Crashlytics for the diagnostics purpose as described in article 2:

Data collected:
– Crashlytics Installation UUIDs
– Crash traces
– Breakpad minidump formatted data (NDK crashes only)

Refer to Examples of stored device information for more detail on the types of user information gathered.

Retention: Firebase Crashlytics retains crash stack traces, extracted minidump data, and associated identifiers (including Crashlytics Installation UUIDs) for 90 days.

The data is collected under the Firebase account of iMKapps and is retrievable via the Firebase Portal. Access to this portal is restricted to 1 employee of iMKapps.

Note that Crashlytics is a different product from Firebase than Analytics. The Firebase Analytics SDK is not integrated in the Service and explicitly disabled in the Service by setting FIREBASE_ANALYTICS_COLLECTION_DEACTIVATED to YES.

  • The Service does not monitor or collect any other information.
  • No other (personal) information whatsoever is send to a server.
  • The Service does not use any (third party) analytics.


We use the information we collect to:
– Improve the quality of the Service by understanding the root causes of app crashes and preventing them by releasing app updates.


As listed in article 1, we do not have any users’ personally identifiable information in our possession.
Nevertheless, we will not sell, trade, or rent any information to others, whether it’s anonymous or users’ personally identifiable information.
We may share your (anonymous) information with Law Enforcement, if required to do so by applicable laws.


The Service does not contain any (third party) ad serving technologies.


iMKapps follows generally-accepted industry standards and maintains reasonable safeguards to attempt to ensure the security, integrity and privacy of the information in iMKapps’ possession.

This includes protection of your ATAG user credentials, which are securely stored locally in your device Apple Keychain.

To keep data safe, Firebase employs extensive security measures to minimize access:
– Firebase services encrypt data in transit using HTTPS and logically isolate customer data.
– Firebase restricts access to a select employees who have a business purpose to access personal data.
– Firebase logs employee access to systems that contain personal data.
– Firebase only permits access to personal data by employees who sign in with Google Sign-In and 2-factor authentication.


Any translation of this document into languages other than English is intended solely as a convenience to the non-English-reading public. The official text is the English text and any differences in the translation are not binding and have no legal effect.


We will periodically update this Privacy Policy to reflect changes in our information practices. Please check back regularly, as your continued use of the Service indicates your acceptance of any changes to this Policy.


This Privacy Policy is governed by Dutch law excluding its choice of law provisions.
