Aire sin sustos app (com.jrsoft.alergiasaire) · Last updated: 14 October 2026
In one sentence: this app has no user accounts and your allergies and your places never leave your phone. To give you the forecast it only sends our data website what is essential: the area of about 50 km the place is in and, for the weather, its coordinates rounded to one kilometre.
The data controller is JR Soft, trade name of Javier Román Sáez, the developer of the app. You can get in touch at demual@gmail.com.
This information is kept in the app's private storage and does not leave it. It is completely removed if you uninstall the app or clear its data in Android settings.
In addition, the “More apps by JR Soft” screen checks your SIM card's country at that moment (or, if there is none, the system region) to show only the apps available in your country. It is neither stored nor sent. The Google Play links on that screen carry a tag saying they come from Aire sin sustos, with no data about you.
Android backup. Since version 1.0.3, the app does not let Android's automatic backup upload your allergies, your places or your settings to Google's cloud. It does allow the direct phone-to-phone transfer you make yourself when you change phones (Android 12 or later), so you don't lose them. Earlier versions, which only reached the closed test, could store them in your Google account's backup if you had it turned on: encrypted, managed by Google and with no access by the controller.
This data is generated every day from the models of the Copernicus Atmosphere Monitoring Service (CAMS) and published on our data website, aire-sin-sustos.pages.dev, hosted by Cloudflare. The website is split into half-degree squares (about 50 km across), and the app downloads the one for the place you are looking at. The request only carries the name of the square (for example, “37.0_-4.0”), not the coordinates of the place. We have no servers of our own (the website and its intermediate server run on Cloudflare) and keep no logs; Cloudflare receives your IP address, like any web server, and handles it under its own policy.
The weather comes from the Norwegian Meteorological Institute (MET Norway), but the app does not ask it directly: since version 1.0.3 it asks our data website, on Cloudflare, sending the coordinates of the place rounded to two decimal places, about one kilometre. The website asks MET Norway on its behalf, identifying itself as JR Soft, and keeps the forecast for each point, with nothing about who asked for it, until a day after it expires, to give it to everyone who asks for it. So MET Norway receives no requests from your phone: it gets the coordinates, but not your IP address or anything else about you. We keep no logs of who asks: to stop abuse, the server only counts, for one minute, the requests from each IP address, stored as a cryptographic digest that cannot be turned back into the address and is deleted automatically after two minutes. Cloudflare receives your IP address, as with the pollen data. Versions before 1.0.3 asked MET Norway directly, which, according to its terms, stores the IP address and the coordinates of each request in its logs, in its data centre in Oslo.
When you use your location, the app asks Android itself for the name of the place at those coordinates, and the city search sends Android the text you type. On most phones that service (Android's geocoder) is provided by Google, which handles it under its privacy policy.
As with any app that connects to the internet, the servers the app talks to receive your IP address: Cloudflare (pollen, air and weather data) and Google (place names, advertising and, if configured, remote configuration).
Google may use that IP address to estimate an approximate location, at the level of a city or region, to choose and measure ads and to prevent fraud.
The app includes Google's advertising SDK (AdMob) and therefore declares the com.google.android.gms.permission.AD_ID permission, which gives access to the Android advertising ID. This ID can be reset or deleted in Android Settings → Google → Ads.
Besides the advertising ID, the AdMob SDK collects the app set ID, interactions with the app and with ads (app launches, taps and video views) and diagnostic data (launch time, hangs and energy use). Google uses them to serve and measure ads, for analytics and to prevent fraud, under its own policy, linked under “Third parties involved”.
In the European Economic Area, the United Kingdom and Switzerland, the app shows Google's consent form (UMP) before serving personalised ads. You can change your choice at any time in Settings → Ad privacy.
The ad consent message is shown by Google with wording shared by all its advertising partners, which is why it mentions precise geolocation. According to Google, its ads SDK only uses the approximate location inferred from the IP address, and this app does not pass it the GPS location. You can refuse that use under “Manage options”.
Your allergies and your places never reach the ads. Ad requests are sent without any of that data. If you decline consent, you will see non-personalised ads and the app works exactly the same: no feature is locked.
| Service | What for | Their policy |
|---|---|---|
| Cloudflare | Hosts the website with the pollen, dust and air quality data, and the server that requests the weather from MET Norway | cloudflare.com/privacypolicy |
| MET Norway | Weather forecast, through our website | met.no/en/About-us/privacy |
| Google (Android geocoder) | Place names and the city search | policies.google.com/privacy |
| Google AdMob | Advertising and the consent form | policies.google.com/technologies/ads |
| Google Firebase Remote Config | Adjusting ad slots without publishing a new version (optional) | firebase.google.com/support/privacy |
The pollen, dust and air quality data contains modified Copernicus Atmosphere Monitoring Service information; neither the European Commission nor ECMWF is responsible for any use that may be made of it. The weather forecast is from MET Norway. Both are published under the CC BY 4.0 licence. This app is not affiliated with Copernicus, ECMWF or MET Norway.
The health data you choose (your allergies) is processed only on your device and under your control: it is not disclosed to third parties and the controller holds no copy of it. Location is used to provide the service you ask for, the forecast for your area, and only if you choose to use it. For personalised advertising, the legal basis is your consent, collected through Google's form (UMP) and revocable at any time from the app settings. Non-personalised advertising (if you do not give consent or withdraw it), its measurement and fraud prevention are based on the controller's legitimate interest in funding a free app with advertising (Art. 6(1)(f) GDPR); you can object in Settings → Ad privacy.
Everything the app stores remains until you uninstall it or clear its data.
Google LLC (advertising and the Android geocoder) and Cloudflare, Inc. (our data website) may process data in the United States. Both participate in the EU-U.S. Data Privacy Framework, which the European Commission found adequate on 10 July 2023. MET Norway processes data in Norway, within the European Economic Area.
If you live in the European Union, the GDPR gives you the rights of access, rectification, erasure, restriction, portability and objection. In practice, since this app keeps no data linked to you outside your phone:
You can also lodge a complaint with the data protection authority of your country (Art. 77 GDPR). In Spain it is the Agencia Española de Protección de Datos.
This app is not directed at children under 16 and does not knowingly collect data from them.
If this policy changes substantially, the new version will be published at this same address with a different update date.
This app is not a medical device. It reports environmental levels of pollen, Saharan dust and pollution; it does not diagnose, treat, cure or prevent any illness and does not replace the advice of your doctor or allergist. Levels come from forecast models and, for some pollens, from an indicative calendar: they may not match what is on your street. If you have difficulty breathing, call your local emergency number (112 in Europe).
