Privacy policy

Effective date: 07.11.2026

1. General information

This Privacy Policy explains how the Airlytica mobile application (the “App”), including its widgets and App Clip, uses data.

The App is provided by Kacper Kalicki Tryhard Solutions, Wielogórska 72B/1, 59-220 Legnica, Poland, e-mail: airlytica@tryhard-solutions.app (the “Developer”). The Developer is the controller of the personal data described below.

The App has no accounts. It never asks for your name, email address or phone number.

2. Data we process

2.1. Location and the places you check

If you allow it in iOS, the App uses your device's location while you use it. It uses it to show where you are on the map, to find nearby stations, and to show air quality, pollen and weather for that place. Location is optional. You can also pick places on the map or save your own places. Saved places and favourite stations are stored on your device.

To get data for a place, whether your location, a saved place or a point on the map, the App sends that place's coordinates to these services:

• The Developer's server (Google Firebase Cloud Functions). It receives the coordinates and the App's language and fetches air quality, forecasts and pollen from the Google Air Quality API and Pollen API. Before it asks Google, the server rounds the coordinates to an area of about 2 km for air quality and about 20 km for pollen. It keeps results for that area in a cache for about a day; the cache isn't linked to you. It doesn't save your exact coordinates.
• Apple Weather (WeatherKit), for weather and weather alerts, under Apple's Privacy Policy.
• sensor.community, a citizen network of air sensors, to show sensors near that place on the map.

Data from GIOŚ and from ESA (Educational Anti-Smog Network) is downloaded as station lists and measurements. The App doesn't send them your location.

2.2. Protection against abuse

To protect the server from too many requests, it stores a salted one-way hash of your IP address with a daily request count. These records are deleted automatically after about two days. Firebase App Check, which uses Apple's App Attest, confirms that requests come from the real App.

2.3. Usage statistics (Google Firebase Analytics)

The App uses Google Firebase Analytics to see how the App is used and what to improve. It records events such as:

• screens opened, onboarding steps, map layers and data modes chosen, and searches (the number of results only)
• whether air quality, pollen and weather loaded successfully
• favourites and saved places added or removed (counts and station type, not where they are)
• alert, location and notification permission choices, the App's language and your plan
• paywall views and purchase steps

Firebase also collects technical data: device model, iOS version, app version, an identifier for this installation, and an approximate region worked out from your IP address. Analytics doesn't receive your coordinates. The App doesn't set a user ID, never asks for permission to track you, and can't use your device's advertising identifier.

2.4. Feature requests (WishKit)

In Settings you can open a list of feature ideas, vote, and suggest your own. This uses WishKit. If you submit or vote, WishKit stores your suggestion, your votes and a random identifier. If you choose to enter it, it also stores your email address.

2.5. Purchases

Apple processes subscriptions and lifetime purchases through your Apple Account. The Developer never sees your payment card or full billing details.

2.6. Data on your device

Favourite stations, saved places, alerts and settings stay on your device and are shared only with the App's widgets. Alerts and the daily summary are local notifications. To prepare them, the App refreshes data in the background for your saved places.

3. Purposes and legal bases

• Showing data for a place, alerts and widgets: performing our contract with you (Art. 6(1)(b) GDPR). Access to location is based on the permission you give in iOS, which you can withdraw at any time.
• Protection against abuse and usage statistics: the Developer's legitimate interest in a secure, working and improving App (Art. 6(1)(f) GDPR). You can object at any time.
• Feature requests: your choice to take part (Art. 6(1)(a) GDPR).

Data isn't used for advertising or profiling, and the Developer doesn't sell it.

4. Service providers and transfers

• Google (Firebase Cloud Functions, Firestore, App Check, Analytics, Air Quality API, Pollen API): Firebase privacy information, Google Privacy Policy
• Apple (WeatherKit, App Attest, App Store purchases): Apple Privacy Policy
• sensor.community: sensor.community
• WishKit: wishkit.io

The Developer's server runs in the United States (Google Cloud, us-central1), and some providers may process data there. Those transfers rely on the EU–US Data Privacy Framework or the European Commission's standard contractual clauses.

5. Data retention

• Data on your device: until you delete it or the App.
• Exact coordinates: not stored on the server. Cached data for an area (not linked to you): about a day. IP hash: about two days.
• Usage events: kept by Google for up to 14 months.
• Feature requests: until you ask us to delete them, or until the list is closed.

6. Your rights

Under the GDPR, you have the right to:

• access your data
• have it corrected
• have it deleted (“right to be forgotten”)
• restrict how it's used
• receive it in a portable form
• object to processing
• withdraw consent
• complain to a supervisory authority: in Poland, the President of the Personal Data Protection Office (UODO)

To use these rights, write to airlytica@tryhard-solutions.app.

7. Security

All connections are encrypted. The server accepts requests only from the genuine App (App Check) and stores IP addresses only as salted hashes. Location access is controlled by iOS and can be withdrawn at any time in Settings.

8. Children

The App is not meant for children under 13, and the Developer doesn't knowingly collect their data.

9. Changes to this Privacy Policy

This Privacy Policy may be updated when the App's features or the law change. The current version is always available at this address.
