3. Principles of Personal Data Processing

When processing your data, we follow these principles:

• lawfulness, fairness and transparency (Personal Data is collected and processed only where there are legal grounds for it, and so that you understand why and how we use your data);
• protection of the rights and freedoms, privacy, personal and family secrets of citizens and (or) their other rights, freedoms and legitimate interests;
• data minimisation (we collect only the minimum necessary Personal Data, whose content and volume correspond to the original purposes of processing);
• purpose limitation (Personal Data is collected only for specified purposes and is not processed for other purposes);
• accuracy (Personal Data is corrected, clarified and updated in good time to keep it reliable);
• integrity and confidentiality (we take organisational, legal and technical measures to protect your Personal Data).

4. What Data We Collect

We may process the following categories of Data about you when you use our Website or Application, or when we provide services:

• account data: email address, name, interface language, registration date and sign-in method; for sign-in with Google, your Google identifier and profile picture; for sign-in with a password, the password as an irreversible hash (we never store the password itself); whether your email address has been verified;
• sensor and location data you add: device identifier, location name, its coordinates and elevation, installation parameters (for example for water-level sensors), and the sensor’s measurements;
• device technical data: local IP address on your network, signal strength, supply voltage, uptime and firmware version;
• SMS messages received by the SIM card of an LTE gateway, if you use one: sender number, text and time of receipt;
• group membership and invitation data, if you joined a group: the group, your role, and the email address an invitation was sent to;
• a push-notification token, if you allowed notifications in the Application;
• technical visit data: IP address, HTTP headers, browser and device information, date and time of requests, and cookies.

With your permission, the Application can use your device’s location to choose the nearest city. The location is processed on your device only and is not sent to us.

5. Legal Basis and Purposes of Personal Data Processing

We cannot use your Data without sufficient legal grounds. AirMQ therefore processes Personal Data only if:

• you have given your consent to the processing of Personal Data (in electronic form);
• the processing is necessary for AirMQ to fulfil its contractual obligations to you, including ensuring the operation of the Website and the Application;
• we process Personal Data available in public sources, or Data to which you have given access to an unlimited number of persons.

We use Data about you for specific purposes and process only the Personal Data relevant to them. We may process your Data:

• to give you access to the functions of the Website and (or) the Application;
• to ensure the operation of the devices that measure air quality;
• to offer and provide our services to you;
• to tailor our services to your needs;
• to contact you with notifications, requests and information about our services, the operation of the Website and (or) the Application, and the handling of your requests;
• to send you promotional messages and materials;
• to carry out analytical research by AirMQ or our partners;
• to protect your rights and the rights of AirMQ.

The location, name and measurements of a public location are published on the AirMQ map and through the open programming interface, and are licensed under CC BY 4.0 — by your decision when you add the location (Terms of Use, §4). Your name and email address are not published.

6. How We Protect Your Data

We process your Data in a way that ensures its proper security, including protection against unauthorised or accidental access, destruction, alteration, blocking, copying, provision, distribution and other unauthorised or unlawful processing, against accidental loss, destruction or damage, and against other unlawful actions.

To protect Personal Data during processing, we have implemented a set of legal, organisational and technical measures.

7. Who We Share Your Personal Data With

To achieve the purposes set out in Section 5 of this Policy, with your consent, we may share Personal Data with:

• Brevo (Sendinblue SAS, France) — to send email, for example to verify your email address upon registration;
• Google (Google LLC, USA) — for sign-in with a Google account;
• OpenStreetMap Nominatim (OpenStreetMap Foundation, United Kingdom) — to determine the town from a location’s coordinates when the location is added;
• OpenWeatherMap (OpenWeather Ltd, United Kingdom) — for weather data at a location’s coordinates to assist sensor calibration;
• Firebase Realtime Database (Google LLC, USA) — for the news feed in the Application;
• public air-monitoring projects that show air quality data on a map (sensor.community, narodmon.ru) — only if you enabled data sharing for your location;
• third parties to whom we are required to provide information under applicable law (for example, at the request of state authorities).

8. Where Your Data Is Stored and Processed

Your Personal Data is stored on the territory of the Republic of Belarus in full compliance with applicable law.

Some of the recipients listed in Section 7 process Data in other jurisdictions: Brevo in the European Union, Google in the USA, OpenStreetMap Nominatim and OpenWeatherMap in the United Kingdom. We maintain a proper level of protection for Personal Data in other jurisdictions. Once your Data is transferred to another jurisdiction, all the legal means of data protection remain fully available to you.

By using the Website or the Application, you consent to the cross-border transfer and processing of your Data in other jurisdictions.

9. How Long We Retain Your Data

We keep your Data for as long as necessary to achieve the purposes for which it was collected, and to comply with applicable law and (or) perform a contract with you.

Email-verification links are valid for a limited time and are then deleted. If you remove (archive) a location, its publication stops; measurements already published under CC BY 4.0 remain with those who have received them.

10. Your rights

You have the right to:

• provide Personal Data to the extent you consider necessary and possible;
• withdraw your consent to the processing of your Data at any time without giving reasons (“right to withdraw consent”);
• receive information about which Data we collect and use, for what purposes, on what basis and how, including information about the provision of Personal Data to third parties;
• access the Personal Data we process about you (“right of access”);
• if your Personal Data is incomplete, outdated or inaccurate, demand that it be corrected (“right to rectification”);
• demand that the processing of your Personal Data be stopped, including its deletion and (or) blocking (“right to be forgotten”);
• take other measures provided by law to protect your rights;
• file a complaint with the supervisory authority where you permanently reside or work, or where the alleged violation of your privacy occurred.

How you can exercise your rights

We will assist you in exercising your rights in the manner prescribed by applicable law.

You can change your name and language in your account settings.

Deleting your account. You can delete your account yourself in the account settings of the management panel (panel.airmq.cc) or of the Application, by confirming your email address. Your account and the personal data in it are then deleted, and you are signed out on all devices. The locations and devices you added are not deleted: they stay on AirMQ and are handed over to the administrators, without your name or email address. If you want a location to stop being published, remove (archive) it before deleting your account.

To exercise any of the rights above, send us a request stating your full name, address and the nature of your request to info@airmq.by.
