Privacy
Your day, your device.
Knowday isn't on the App Store yet. This policy describes how the app and this website handle data today — and it's honest about a couple of things we may add later.
The short version
- No account. Knowday works the moment you open it — and your settings sync privately through your own iCloud.
- Your location is used to fetch the forecast — and isn't tied to who you are.
- We don't sell your personal data. We may add usage analytics and possibly ads later — and we'll say so here first.
A note while we're getting started. Knowday isn't on the App Store yet. This policy describes how the app and this website handle data today, and it is honest about a couple of things we may add later (like understanding how the app is used, and possibly showing ads). If those change, we'll update this page and the App Store privacy details before turning anything on.
The short version
- No account. You don't sign up, log in, or give us your name or email to use Knowday.
- Your location is used to get your forecast — and that's all it's for. It isn't tied to your identity.
- We don't sell your personal data.
- We may add basic usage analytics and possibly ads in the future. If we do, we'll say so here first and update our App Store privacy details. (See "What might change later.")
What the app does with your data today
To tell you what today is good for, Knowday needs to know roughly where you are:
- With your permission, the app uses your device location to fetch the forecast for your area. You can also type a city or ZIP code instead.
- Your approximate coordinates are sent to our weather data provider (Open-Meteo, see below) to retrieve the forecast. They're used to get the forecast and nothing else.
- Knowday rounds location to an area grid (about an 11 km cell) rather than a pinpoint, so a precise spot isn't needed to give you a useful read.
- There is no account, so your location and your settings aren't connected to an identity.
- Your preferences (the lenses you pin, units, etc.) are stored on your device.
Syncing your settings across devices
Your Knowday settings — such as your saved locations, the activity lenses you pin, and your preferences — sync through your own iCloud account so they stay consistent across your devices. This data is stored in Apple's iCloud under your Apple ID; Knowday can't read it, and if you're not signed into iCloud the app works exactly the same with your settings kept only on your device. Only the places you save sync — your device's current location is never synced; each of your devices figures out where you are on its own.
Third-party services
- Open-Meteo provides our forecast data. To get your forecast, the app sends Open-Meteo your approximate coordinates. We don't send a name, email, device ID, or account — there isn't one. See Open-Meteo's terms and privacy information at open-meteo.com.
What might change later (told honestly, up front)
We want Knowday to get better, and to keep it sustainable. So we may, in the future:
- Add usage analytics / telemetry to understand how the app is used (for example, which features people rely on and where the app is confusing), and
- Show advertising.
If we do either, it could involve things like device identifiers, usage data, and third-party analytics or advertising tools. We're disclosing this now so it isn't a surprise. Before we turn any of it on, we will update this policy and update the privacy information shown on our App Store listing, and — where it applies — give you a way to opt out (see "Your choices"). We are not doing these things today.
App Store privacy details — how we answer the questionnaire
This is the conservative, honest mapping we use for Apple's App Privacy questions, for the current (pre-analytics, pre-ads) build.
| Data category | Current state | Notes |
|---|---|---|
| Location (coarse / approximate) | Collected — App Functionality. Not linked to you. Not used to track you. | Sent to Open-Meteo only to fetch your forecast; no account, no identity. |
| Usage Data | Not collected today. May collect in the future (analytics). | Will be re-declared before enabling. |
| Identifiers | Not collected today. May collect in the future (analytics / ads). | Will be re-declared before enabling. |
| Diagnostics (crash / performance) | Not collected today. May collect in the future. | No third-party crash SDK today; if standard crash reporting is added, this row will be re-declared before submission. |
Rule we follow: when in doubt, we pick the more conservative answer and disclose the future possibility in plain language rather than under-declaring.
iCloud-synced settings (your saved locations, pinned lenses, and preferences) are stored in your own iCloud under your Apple ID. They're not collected by us and Knowday can't read them, so they aren't part of this developer data-collection table.
Children
Knowday is not directed to children under 13, and we don't knowingly collect personal information from children under 13.
Your choices
- Location: you control Knowday's location permission anytime in iOS Settings → Privacy & Security → Location Services, or skip it entirely and enter a city / ZIP instead.
- Analytics / ads (if and when added): if we add usage analytics or advertising, we'll provide a way to opt out at that time and explain it here. Until then, there's nothing to opt out of.
Data retention & where processing happens
- Your preferences live on your device and are removed if you delete the app. When you're signed into iCloud, they also sync through your own iCloud account (see "Syncing your settings across devices").
- Forecast data is cached on your device for a short time to keep the app fast and to limit network calls, then refreshed.
- We don't run a Knowday server that stores your personal data. Forecast requests are handled by Open-Meteo to return your forecast.
This website
Our marketing site (knowday.app) currently uses no analytics. If we ever add privacy-respecting, cookieless analytics — aggregate page-view counts only, with no profile of you — we'll update this page first.
Changes to this policy
If we change how we handle data, we'll update this page and change the effective date at the top. For meaningful changes (like turning on analytics or ads), we'll update our App Store privacy details too.
