Pluvio Privacy Policy

At a Glance

Pluvio is a virtual rain gauge for the contiguous United States. It has no accounts and shows no ads. To read the rain at your places and send your alerts, Pluvio's server receives the places you save — where they are and the names you give them — and keeps them until you delete them. Usage statistics and crash reports help us fix and improve the app. We do not sell your information.

1. Information We Process

1.1 Your Places

When you save a place — with your location, by searching an address or by dropping a pin — Pluvio sends its coordinates and its name to our server. The server uses the coordinates to find the radar cell, about a square kilometer, that the place falls in, and uses that cell to compute the place's rainfall, check your alerts and write your 7 AM report. The name appears in your notifications. A name that comes from an address search can be the street address itself; you can rename any place.

1.2 Location Permission

Pluvio asks for your location only when you tap "Use my location", and only for while you are using the app. If you decline, you can search an address or drop a pin instead. You can change the permission at any time in iOS Settings → Pluvio.

1.3 Alerts, Reports and Settings

Your alerts (which place, what amount, over what window, and whether they arrive right away or in the morning report), whether you receive the 7 AM report, and your time zone, language and units are stored on our server, because the server decides when a rain day ends and when an alert fires.

1.4 Notifications

If you allow notifications, your device's push token is registered with our server together with its identifier for vendor (IDFV), device model, iOS version, app version and language, so that alerts and the 7 AM report can be delivered through Apple Push Notification service. You can turn notifications off at any time in iOS Settings → Pluvio.

1.5 No Account

There is nothing to sign up for. Pluvio identifies each installation with a key created through Apple's App Attest service. The key is held in your device's secure hardware; our server stores the key's identifier to recognize requests from your installation and to keep other apps and devices from using Pluvio's service.

1.6 Usage Statistics, Diagnostics and Ad Attribution

To understand how Pluvio is used and to find and fix problems, Pluvio sends us:

usage events, such as app opens, screens viewed and taps on Pluvio's controls, and purchase events (product, price, currency and transaction identifiers);
crash reports, hang reports and performance measurements, such as stack traces and how long requests take;
App Store ad attribution: if you installed Pluvio after tapping an Apple Search Ads ad, Apple's AdServices framework gives Pluvio a token that we use to learn which campaign led to the install, together with your tracking-permission status and country. Pluvio does not access your device's advertising identifier (IDFA) and does not ask for permission to track you.

These carry a random installation identifier that Pluvio stores in the iOS keychain, where it can remain after you delete and reinstall the app, along with your app version, device model, iOS version and language.

1.7 Feedback

If you send feedback from Settings, we receive your message, any photos you attach (re-encoded, which removes their location and other metadata), your device model, iOS and app version (you can switch these off), and an email address if you choose to enter one, so that we can reply.

1.8 Stored on Your iPhone

Pluvio also keeps your places, the readings it has fetched, your settings and your gauge log on your iPhone, where its widgets read them. Your gauge log — the amounts you record from your own rain gauge — is not sent to our server.

2. How We Use Information

We use this information to:

compute rainfall for your places and send your alerts and the 7 AM report;
deliver notifications;
recognize your installation and protect Pluvio's service from misuse;
diagnose crashes and failures, measure performance and improve features;
understand which App Store campaigns bring people to Pluvio;
respond to your feedback.

We do not sell your information, and we do not share it with third parties for their own advertising.

3. Apple Services and Service Providers

Maps and address search use Apple's MapKit. What you type into search and the map areas you view are sent to Apple and handled under Apple's privacy policy.
Purchases are processed by Apple through the App Store. We never see your payment details.
App Attest, push notifications and ad attribution are provided by Apple.
Rainfall data comes from NOAA's Multi-Radar/Multi-Sensor System, which our server downloads; no information about you is sent to NOAA.

Our servers run on cloud infrastructure that processes data on our behalf. Data may be processed in countries other than the one where you live, including outside the United States. Where required, we use appropriate safeguards for international transfers.

4. Retention and Deletion

Your places, alerts and settings stay on our server until you delete them. Deleting a place in Pluvio removes it and its alerts from our server.
Settings → Privacy → Delete my data removes your installation from Pluvio's server — places, alerts, report history and settings — and erases Pluvio's data on your iPhone. Your Pluvio Pro subscription stays with your Apple ID.
Deleting the app does not delete your places from our server. Use Delete my data first.
Delete my data does not remove usage statistics, diagnostics or your device's notification registration. Usage events are deleted after 90 days, performance measurements after 30 to 90 days, crash reports after one year, and ad-attribution and purchase records after two years. Statistics computed from them, such as daily totals, may be kept longer.

5. Your Choices

You can rename or delete any place, turn alerts and the 7 AM report on or off, and use Delete my data at any time. Location and notification access can be changed in iOS Settings. Depending on where you live, you may have rights to access, correct, delete or receive a copy of your personal information; contact us to exercise a right that is not available directly in the app.
