Retrospectrum — Privacy Policy

Last updated: 29 October 2026

Retrospectrum is a diary of how evenings felt: what happened, how fun it was, how planned, and who was there. That is about as personal as data gets, so this page says plainly where it goes. Mostly, nowhere.

The short version

Your events never leave your device for us. There is no Retrospectrum server that receives them, no account to sign in to, and nothing we can read.

There are no adverts, no analytics, no tracking, and no third-party SDKs of any kind.

What stays on your device

All of this is stored in the app's own storage on your device, and is included in your device backup if you have one:

WhatWhy
Your events: label, date, optional time, the two ratings, people, places, tags and a one-line noteIt is your diary
Ratings made later: predictions before an event, and re-ratings afterTo show how memories and predictions shift
A photo, if you add one to an eventA downscaled copy (at most 1600 pixels), re-encoded so none of the original's metadata — including its location — is kept. Your original photo is untouched
Settings: app lock, reminders, how long events stay on the compass, widget labelsSo the app behaves the way you left it
A small summary for the widgets: event positions, and labels only if you turn labels onSo the widgets can draw your compass. It is stored in a container shared only with Retrospectrum's own widgets

Deleting the app deletes all of it.

What the app can reach, and only when you turn it on

Each of these is off until you choose it, and each can be turned off again in the app or in your device's Settings.

Calendar (read). If you allow it, the app reads your calendar on the device to send you a "how was it?" prompt when an event ends, or an offer to predict one before it starts. A calendar event's title is only a suggestion: nothing from your calendar is saved unless you save the entry yourself.

Health (write only). If you turn it on, each rated event is written to Apple Health as a State of Mind: its Foul-to-Fun rating, its date and any matching associations (such as friends or family). The Intentional-to-Impulsive rating is not written. Retrospectrum never reads anything from Health. Not available on the Mac.

Photos. When you add a photo, you pick that one photo with the system picker; the app has no access to the rest of your library.

Notifications. Reminders — a month-later re-rate, an anniversary, a prediction to rate, a calendar prompt — are scheduled on your device. There is no push server. A reminder can name the event or calendar event it is about; with app lock on, none does, since notifications show on a locked screen.

Siri and Shortcuts. Logging an event by voice or from a shortcut writes it to the same store on your device. Apple processes the speech under Apple's own terms; Retrospectrum receives only the event.

Face ID, Touch ID or passcode. App lock asks the system to check it's you. The app never sees your face, fingerprint or passcode, only whether the check passed.

iCloud sync (Pro). If you turn it on, your events sync between your devices through your own iCloud account's private database. Apple stores it, encrypted, under your account; we cannot read it. With sync off, your events are only on the device you made them on.

What you choose to send

Exports and share cards. Export writes your events to a file, and the annual recap can make a share card or a poster image. Each file is made on your device and goes only where you send it. A share card or poster leaves names out unless you ask for them.

What we never do

Purchases

Pro and any other purchase go through the App Store. Apple handles payment; we receive no card details, and no name or email address.

Deleting your data

Delete an event and it is gone from the device (and from Health, if you also choose that when deleting). Deleting the app removes everything it stored on the device. With iCloud sync on, your synced copy is in your iCloud account, where you can delete it from iCloud settings.

Children

Retrospectrum is not directed at children and collects nothing from anyone. It has no accounts, no messaging, and nothing anyone else can see.

Changes

If this policy changes, the date at the top changes with it, and material changes are noted in the app's release notes.
