Saturn
Remembers everything. Shares nothing.
Type or speak it the way you'd say it out loud. On-device AI turns your words into perfectly scheduled reminders — and not one byte ever leaves your iPhone.
How it works
Say it once. Saturn does the rest.
Watch a real phrase become a real reminder — the same flow that runs on your phone, offline, in a fraction of a second.
-
You talk like a person
“Pay credit card bill on the 15th every month.” No fields, no pickers, no date wheels.
-
Apple Intelligence reads it
Apple's on-device model extracts the title, category, date, time and repeat rule. A built-in parser covers every other iPhone.
-
You confirm — it schedules
Reminders fire a week before, the day before, and on the day. Mark done or snooze right from the notification.
Features
Built for the life you actually live
Bills that never sneak up
Rent, cards, loans, subscriptions. Get nudged a week out, the night before, and the morning of.
Medicine, on the dot
“Take blood pressure medicine every morning at 8.” Daily doses, refills, checkups — handled.
Plans you don't drop
Appointments, birthdays, flights. Saturn understands “next Friday” and “every mon wed fri at 7pm.”
Speak it, don't type it
Dictation runs entirely on-device. Your voice is transcribed on your phone and never uploaded.
Insights, for your eyes only
Completion rate, streaks, and a two-week activity chart — computed on device, shared with no one.
Nothing is ever lost
Undo any delete. Restore anything you finished. Pause a reminder instead of throwing it away.
Privacy
Private by architecture,
not by promise.
Most apps promise not to misuse your data. Saturn simply never has it. There is no server to send it to — the app makes zero network requests.
- ✓ No account, no sign-in, no email
- ✓ No cloud sync, no servers, no network calls
- ✓ No analytics, no trackers, no third-party SDKs
- ✓ AI parsing and voice run on your device
Saturn remembers everything.
And shares nothing.

Privacy Policy
There is no account, no server, and no analytics. The app makes no network requests of its own. Everything you write, say, and schedule stays on your iPhone. The rest of this page simply explains that in detail.
What we collect
Nothing. Saturn has no backend, no user accounts, no sign-in, no email capture, no advertising identifiers, no crash reporting service, no analytics SDK, and no third-party libraries of any kind. Our App Store privacy label reads “Data Not Collected” because there is nothing to collect.
What stays on your device
Saturn stores the following locally, in Apple's on-device database, and nowhere else:
- Your reminders — titles, notes, categories, dates, and repeat rules
- The original phrase you typed or spoke, kept so you can review what was parsed
- Your completion history, used for the Done list and Insights
- Your settings, such as default reminder times
This data is protected by iOS file-system encryption and is included in your encrypted iPhone or iCloud device backup, exactly as any other app's local data is. Saturn itself never uploads it. Deleting the app deletes all of it.
Artificial intelligence, on your phone
When you write “pay credit card bill on the 15th every month,” that sentence is interpreted by Apple's Foundation Models framework — a language model that runs entirely on your device. On iPhones without Apple Intelligence, Saturn falls back to its own built-in parser, which is also fully on-device. Your words are never transmitted to us, to Apple, or to anyone else.
Microphone and speech recognition
If you choose to dictate a reminder, Saturn asks for microphone and speech
recognition permission. Transcription is pinned to on-device recognition
(requiresOnDeviceRecognition), so your audio is converted to text
on your iPhone. Saturn does not record, store, or transmit audio. If you never
tap the microphone, these permissions are never requested.
Notifications
Reminders are delivered as local notifications, scheduled by your iPhone itself. Saturn uses no push server and no remote notifications, so no device token is ever created or shared.
The one time the network is touched
Saturn makes no network requests. In one situation, iOS may make one on its own behalf: the first time you dictate in a given language, the operating system may download that language's speech-recognition model, the same way it does for the system keyboard's dictation. That download is performed by Apple's software, is governed by Apple's Privacy Policy, and carries none of your reminder content. We mention it because we would rather over-explain than let you find a surprise in a network log.
Insights
Saturn's Insights screen — your completion rate, streak, and activity chart — is computed on your device from your own reminders, each time you open it. Nothing is aggregated, uploaded, or shared. They are statistics for you, not about you.
Children
Saturn is rated 4+ and is safe for all ages, for the simple reason that it collects no personal information from anyone, children included.
Your rights
Regulations such as the GDPR and CCPA grant you rights to access, correct, export, and delete the personal data a company holds about you. We hold none. Your data lives on your iPhone, under your control: edit or delete any reminder in the app, or delete the app to remove everything at once.
Changes to this policy
If Saturn ever gains a feature that changes any of the above — it has no such plans — this page will be updated before that version ships, and the change will be described in the App Store release notes. The date at the top of this page always reflects the current version.
