Hale Privacy Policy
Hale collects no data. Your readings stay on your iPhone.
Hale is an iPhone app for AirGradient air quality monitors, made by Taylored Labs. This page explains what Hale does with information on your phone. In short: we have no servers, and nothing leaves your device for us unless you send it yourself.
What we collect
Nothing. Hale has no account, no analytics, no advertising, no crash reporting service and no third-party SDKs. We never receive your readings, your location or your monitors, and we receive nothing about how you use the app unless you send it to us yourself, such as an email or a diagnostic report (see below).
Your monitors
Hale reads your AirGradient monitors directly over your home Wi-Fi. Readings, history and settings are stored on your iPhone and shared only with Hale's own widgets on the same device.
Your AirGradient account (optional)
If you add an AirGradient API token, Hale stores it in the iPhone Keychain and uses it only to fetch your monitors' data from AirGradient's servers (api.airgradient.com) when you are away from home. That exchange is between your phone and AirGradient, under AirGradient's privacy policy.
Public outdoor monitors and location
To compare indoor air with outdoor air, Hale downloads AirGradient's public list of outdoor monitors. If you ask it to find the nearest one, Hale reads your location once and does the matching on your iPhone. Your location is never stored and never sent anywhere.
Apple Home
If you set up Home actions, Hale uses Apple's HomeKit on your iPhone to run the scene or switch the accessory you chose. Hale does not copy your Home data anywhere.
Purchases
Hale Pro is bought through the App Store. Apple handles payment; Hale only learns whether Hale Pro is active on your Apple Account, so it can unlock the features. See Apple's privacy policy.
Crash and hang reports
If Hale crashes, freezes or runs slowly, iOS gives Hale a report about it the next time it opens. Hale keeps the newest ten, for up to 30 days, on your iPhone only (they are left out of iCloud and computer backups), in Settings → Diagnostic reports, where you can see or delete them. Each report is written by iOS. It describes what Hale's code was doing when the problem happened, with device and app details such as the app version, iPhone model, iOS version, region and Low Power Mode. Hale adds none of your readings, locations or account details.
A report reaches us only if you email it to us from that screen: a short summary you can read and change, with the full report attached. Separately, if you have chosen to share analytics with app developers (Settings → Privacy & Security → Analytics & Improvements on your iPhone), Apple may share crash reports with us. That is Apple's feature, covered by Apple's privacy policy.
Children
Hale collects no personal information from anyone, including children.
Changes
If this policy changes, the new version will be posted here with a new date.
