AirTruth privacy policy

Last updated: 27 October 2026

Who we are

AirTruth is a free air quality app for India, made by AYERIQ AI LABS. It has no accounts, no ads and no analytics. This policy explains what the app keeps on your phone, what it sends and when, and what you can do about it.

What stays on your phone

• Your location. The app uses it to find the nearest air quality monitor, and an approximate location is enough. It is kept in memory only, with one exception: if you allow location during the first run, the app saves your position at that moment as a place called “Home”, so the morning digest has somewhere to report on. You can rename or delete it in Places.
• Your saved places: the names you give them and their positions or monitors.
• Your settings, such as the advice group, theme and alert choices.
• Cached air quality data, so the app can show the last readings when it cannot refresh.
• An install id: a random number that identifies this installation of the app, not you.
• The app’s signed configuration, which the app downloads.

You can clear the cached data in Settings → Clear cached data. Uninstalling the app removes everything on this list.

What leaves your phone and when

Every time the app refreshes, it downloads public air quality data and the app’s configuration. These requests go to:

• OAQ’s servers, including its session service on Google Cloud;
• the AirTruth server on Cloudflare;
• OpenFreeMap, for the map tiles.

Like any request on the internet, each one carries your phone’s IP address. None of them contains your coordinates. But the app asks for the readings of the monitor nearest you and for the map tiles around you, so these services can tell roughly which area you are in. The AirTruth server also uses your IP address to limit abuse, and Cloudflare keeps the server’s request logs for a few days.

Only if you turn on alerts (the morning digest or a place’s alerts), the app sends these details to the AirTruth server:

• the install id and your phone’s push token, so that pushes reach this phone;
• your time zone and digest time, and whether the digest is on;
• the alert level you chose (Poor, Very Poor or Severe);
• the time you turned alerts on, as the record of your consent;
• for each saved place: the name you gave it (such as “Home” or “Riya’s school”), whether its alerts are on, and either its position rounded to about 110 metres or the id of the monitor you saved.

The place names appear in the pushes you receive. Turning alerts on is your consent to this. Nothing on this list is sent while alerts are off.

To send the alerts, the server also keeps, for your installation, a hash of a secret that only your phone holds, the day it last sent your digest, and for each place the last level it saw and when it last sent a push, so that it does not repeat an alert. All of it is deleted with your registration.

Why

The details above are used only to send you the alerts you asked for: which places to check, how bad the air must get before we tell you, and when to send the digest. They are not used for anything else, not sold and not shared, except with the push services listed under Third parties, which deliver the pushes.

Retention

A registration that the app has not updated for 90 days is deleted from the server automatically.

Your rights

• Erasure. Settings → Delete my alert registration deletes your registration from the server at once and turns your alerts off.
• Access and correction. The server holds exactly the details listed above, and the app’s Settings and Places show every one of them, where you can also change them. The server knows your installation only by its random install id, never by your name or email, so we cannot match an email to a registration. For any question about your data, email privacy@ayeriq.com.

Children

AirTruth is not directed at children under 18, and it collects no information about age.

Third parties

• OAQ provides the air quality data, and its session service runs on Google Cloud.
• Cloudflare hosts the AirTruth server and this site.
• OpenFreeMap serves the map tiles.
• Push delivery. When alerts are on, the AirTruth server hands each push, including its text, to Expo’s push service. Expo delivers it through Google’s Firebase Cloud Messaging on Android, and through Apple’s push service on iOS.

Crash reports

This version of AirTruth sends no crash reports. If a later version adds them, they will be off unless you turn them on, will contain no personal data, and this policy will be updated first.

Grievance and contact

For any question or complaint about your data, write to our grievance contact at privacy@ayeriq.com. We acknowledge every message within 72 hours. This policy is written to follow India’s Digital Personal Data Protection Act, 2023. For anything else about the app, write to airtruth@ayeriq.com.

Changes to this policy

When this policy changes, the date at the top changes with it. A change to what the app sends is made here before the version of the app that makes it is released.
