Tempered StudioToday Hub is designed to keep your information on your device. This policy explains, in plain terms, what the app accesses, what it sends, and what it doesn't do.
The short version
Today Hub reads your calendar, reminders, and meal plan directly on your iPhone to show them back to you. That information never leaves your device and is never sent to us — we don't operate a server that receives it. Your habits and the days you log, including anything you write in a day's note, are backed up to your own private iCloud account, which we cannot read. The only data that leaves your phone and reaches a third party is your approximate location, sent to a weather provider to fetch your local forecast. We have no account system, run no analytics, show no ads, and sell nothing.
What the app accesses on your device
- Calendar & Reminders. With your permission, the app reads your events and reminders to display today's schedule and the week ahead. It can also mark a reminder complete or change its due date at your request — these changes are written back to Apple Reminders on your device (and sync through your own iCloud account, if enabled). None of this data is transmitted to us or stored anywhere outside your device and your iCloud.
- Meals. If you designate a calendar for meals (for example, one you export from a recipe app), the app reads those entries the same way it reads any calendar — locally, on your device.
- Habits. Habits you create in the app — their names, the dates you marked them complete, and the order you arranged them in — are stored on your device and backed up to your private iCloud database. See Habits, logged days, and iCloud below.
- The days you log. A day's rating, the note you write about it, and a snapshot of that day's habit count, event count, completed reminders and weather are stored on your device and backed up to your private iCloud database, the same way habits are. The note is free text you write yourself and is the most personal thing the app holds; it is never transmitted to us and never leaves your own iCloud. The Look Back screen reads these entries back to you on your device and sends nothing anywhere.
- Location. With your permission, the app requests your location at reduced accuracy — roughly city-level, not your precise position — to fetch local weather. You can skip location permission entirely and type a ZIP code instead.
- Notifications. With your permission, the app schedules a morning and evening summary, and a reminder to log your day. These are local notifications, composed and delivered on your device. Their contents are never sent anywhere.
- App settings. Your preferences — which calendars to include, meal calendar, units, theme, notification times, haptics — are stored locally using iOS's standard settings storage, in a container shared with the Today Hub widget.
Opening other apps
Some rows in Today Hub hand off to the app that owns the thing you tapped: an event opens Apple Calendar, a reminder opens Apple Reminders, and — if you turn it on in Settings — a meal opens the recipe app you chose. These handoffs pass only what iOS needs to open that app to the right place. Nothing about you is sent to us, and no third-party code runs inside Today Hub.
The meal setting lists a small, fixed set of recipe apps and shows whether each is installed. That check is made by iOS on your device against a list declared in the app, and the answer stays on your device.
Habits, logged days, and iCloud
So your habits and logged days survive a new phone or a reinstall, they are synced through your own private iCloud database using Apple's CloudKit. This is the same mechanism Apple's own apps use, and the important detail is who can see it: the data lives in your personal iCloud account, governed by Apple's privacy policy. We have no access to it, no ability to read it, and no copy of it. There is no Tempered Studio server involved at any point.
Habit completion history is kept to a rolling 365-day window; older entries are discarded automatically. If you sign out of iCloud or turn off iCloud for Today Hub in iOS Settings, the app keeps working and stores habits and logged days only on your device.
To support this sync, the app receives silent background notifications from Apple telling it that your iCloud data changed. These carry no content of their own and are not marketing messages.
What leaves your device
To show weather, the app sends your approximate latitude and longitude to:
- Apple Weather (WeatherKit) — for temperature, precipitation chance, UV index, and sunrise/sunset. This is the app's usual source, and requests are handled under Apple's privacy policy.
- Open-Meteo (open-meteo.com) — the same forecast details, used only when Apple Weather is unavailable. The app tells you which source answered.
- National Weather Service (weather.gov) — for any active severe-weather alerts in your area (United States).
The Today Hub widget makes these same weather requests independently, so it can stay current while the app is closed.
These requests contain only coarse location coordinates. They do not include your name, your device identifier, your calendar, your reminders, your habits, your logged days, or your meals. The coordinates are used to return a forecast and are not linked to your identity by the app. Please refer to each provider's own privacy terms for how they handle incoming requests.
Purchases
Today Hub offers an optional one-time purchase, Today Hub Premium, which unlocks your full history in Look Back, unlimited habits, the additional color themes, and the alternate app icons. Purchases are handled entirely by Apple through the App Store. We never see or receive your payment details, card number, or billing address — the app only ever learns whether an unlock is active on your Apple Account.
What we don't do
- No user accounts, sign-in, or profiles.
- No analytics, tracking, crash reporting, or advertising SDKs.
- No selling or sharing of personal data.
- No cross-app or cross-site tracking. The app does not use the Advertising Identifier (IDFA).
- No servers of our own. There is nowhere for us to collect your data even if we wanted to.
Data retention and deletion
Because your calendar, reminders, meals, habits, and logged days are never collected by us, there is nothing on our side to retain or delete. App settings, habits and logged days stored on your device are removed when you delete the app. Anything already backed up to iCloud is removed by turning off iCloud for Today Hub, or by deleting the app's data in iOS Settings › your name › iCloud › Manage Account Storage. Your underlying calendar and reminder data is managed by iOS and is unaffected by removing this app.
Children
Today Hub is a general-audience utility and does not knowingly collect information from anyone, including children.
