Tiny Days privacy policy

Last updated: 11 November 2026

Tiny Days is a mood tracker. This page explains what happens to the information you put into it.

The short version

Your moods, notes, tags, medication, symptoms, period days and trackers are stored on your device and, if you use iCloud, in your own private iCloud account. We cannot see them, and we run no server that receives your entries. You sign in with Apple or Google, and we keep a small account with your name and email (see below). If you join a friends circle, the people in it see your daily mood and anything else you choose to share.

What the app stores

• Your entries. Moods, notes, tags, medication names and doses, dose times, symptom ratings, period days if you choose to track your cycle, and the trackers you add, such as sleep, calories, water, caffeine, steps and exercise. These are saved on your device. If iCloud is turned on for Tiny Days, they are also saved in your private iCloud database so they appear on your other devices. That data is held by Apple under your Apple Account, and we have no access to it.
• Your settings. Reminder times and similar preferences, stored on your device.

Your account

You sign in to Tiny Days with Apple or Google. We keep a small account on our server: a random account ID, the ID Apple or Google gives us for you, your name if you share it, and your email address (which may be a private relay address from Apple). We use it to keep your place and your Pro purchase for Tiny Days on other platforms. Your entries are not stored in your account; they stay on your device and in your iCloud.

RevenueCat links your purchases to your account ID.

Emails from us

By signing in, you agree that we may email you about Tiny Days: new features, tips, offers and news such as Tiny Days coming to other platforms. Every email has an unsubscribe link, and unsubscribing doesn't affect your account or the app. We don't sell or share your email address.

If you live in the EU, the EEA, the UK, Switzerland or Canada, we only email you about your account unless you tell us you'd like news too.

You can sign out or delete your account in Settings. Deleting it removes it from our server straight away, and if you signed in with Apple it also revokes Tiny Days' access to your Apple ID.

Friends circles

Circles are off unless you start or join one. A circle is shared through iCloud, not through your Tiny Days account, and the shared information is held by Apple in iCloud, not by us. We cannot see it.

People in your circle see your character, its name and your mood each day. They also see your last seven days or a short note only if you turn those on. Your notes in the app, tags, trackers, medication, symptoms and period days are never shared. People in a circle can send each other nudges.

Leaving a circle removes your information from it. Ending a circle you started removes everyone and deletes what was shared in it.

Summaries and suggestions

The patterns Tiny Days shows are worked out on your device.

AI summaries are off unless you turn them on. If you do, Tiny Days sends a few sentences describing your patterns (averages, streaks, the names of your tags and symptoms, and how your mood shifts through your cycle) together with an anonymous install ID to our server, which passes the sentences to an AI provider (Google or OpenAI) to write the summary. Your notes, medication, trackers (such as sleep or calories) and individual days are never sent. We do not store what is sent or what comes back. You can turn AI summaries off in Settings at any time.

On iPhones with Apple Intelligence, a summary can instead be written by the language model built into the phone, and then nothing is sent anywhere. Summaries are not medical advice.

The answer you give to "Which describes you?" when setting up the app stays on your device.

Purchases

Tiny Days Pro is sold through the App Store. Apple handles payment, and we never see your card or billing details.

We use RevenueCat to check whether a purchase is active. RevenueCat receives an anonymous, randomly generated ID for your install, the products you bought and when, and basic device information such as the app version and country of the App Store account. It does not receive your name, your email address or anything you have logged in the app. RevenueCat's privacy policy is at https://www.revenuecat.com/privacy.

Notifications

Reminders are scheduled on your device. Nothing about them is sent anywhere.

Analytics and advertising

Tiny Days has no advertising and does not track you across other apps or websites. This version does not collect usage analytics.

Deleting your data

• "Erase all entries" in Settings deletes every mood, dose, symptom, period day and tracker amount you have logged.
• Deleting the app removes its data from your device. To remove the iCloud copy, go to Settings, your name, iCloud, Manage Account Storage, and delete Tiny Days data.

Health information

Tiny Days is a personal journal. It is not a medical device, it does not diagnose or treat any condition, and it is not a substitute for advice from a doctor.

Children

Tiny Days is not directed at children under 13.

Changes

If this policy changes, the new version will be posted at this address with a new date.
